Saving Water in livestock (Portugal)

Livestock is commonly defined as domesticated animals raised in an agricultural setting to produce labour and commodities such as meat, eggs, milk, fur, leather, and wool. Saving water in Livestock production plays an important role in Portugal.

The training programme will be focused on different methods used by various farmers and specialists to lower the consumptions of water on animal farms. It will also consist on topics such as usage and recycling of water in agriculture, using water for farm animals in welfare, way of education and consultancy, EU subsidies and taken governmental measures.

Prados de Melgaco (Goat farm)

As part of a project to exchange good experience and practice, we had the opportunity to visit an organic goat farm Prados de Melgaco. There are kept 240 female goats, 2 male goats and 1 donkey on this family farm. Goats are housed in the stable freely in various groups. Animal welfare is maximally ensured in the stable. According to the owner, a subsidy from the European Union was used to meet all the conditions for goat welfare. The hutchs are equipped with drinking water drinkers, scratchers and hay cribs. Into the trough, goats receive complete core feed in granular form, which is purchased from the production of feed mixtures in the area. Hay owners also buy from farmers on the border with Spain. Thus, all feed is provided from purchased sources. Mineral nutrition of goats is carried out in the form of mineral licks placed in each hutch. There are no grazing conditions in the given locality, and therefore the goats are closed in the stable all year round. Classical music plays from the speaker for more animal comfort. Thanks to the provision of clean bedding and a good climate in the stables, goats produce milk of a good quality without any negative odors that could pass into the milk if the environmental conditions are not met.

Milking of goats is performed on a modern parallel milking parlor for 2 x 10 goats, with 10 milking parlors common for both sides of milking. This milking parlor is from the DeLaval brand. To motivate goats to milk, grain is added to the milking parlor in the form of whole barley.

After milking, the milk is transferred to cooling tanks, from where it is pumped for processing to a farm dairy, where mainly French-type cheeses are produced. This dairy was built with the support of the European Union. Due to high hygiene rules, it was not possible to see the dairy physically. The process of milk processing in the dairy was performed in the form of a video, where it was possible to see the process of processing the milk produced. Subsequently, the cheeses produced were tasted. In addition to fresh cheese, we also tasted ripened cheeses that ripen for 30 days and cheeses flavored with spices and wine after 40 days of ripening.

The owner explained how she uses water resources on the farm. The goats are fed in the form of drinkers with drinking tap water. Utility (rain) water is used on the farm mainly for rinsing and cleaning in the milking parlor and stable and for irrigation of vineyards (drip irrigation), which line all the surroundings of the farm and dairy.

Quinta de Pregal (Livestock)

The last breeding visited was the QUINTA DE PREGAL farm, which deals with the breeding of Barroso beef cattle, kept in a clean line. The owner of this farm comes from an agricultural family. He studied agricultural school and after returning from studies in 2018, he decided to resume beef cattle breeding and meat production. This farmer farms only 10 hectares of land and despite this small volume of land is profitable.

The animals are found outside on the pasture all year round, where calves are also born. The feed base of the cattle is mainly pasture rich in herbs, followed by corn silage and hay grown only on their own land. Animal welfare is taken care of in breeding.

After fattening, the farmer has the young cuts slaughtered and sells the meat directly from the farm in 10 kg packages. Its customers are also more luxurious hotels.

When it comes to water and water management, surface water is used there. This water is cleaned of impurities with the help of plants and then led through a riverbed around the pasture. The water is of high quality despite the fact that it is surface. Cows go to drink in the riverbed, as it is the only available source of water for the herd. Despite the fact that it is surface water, thanks to these channels there is a continuous movement of water and thus the safety of water.

In Chrudimi, 19. 8. 2021

Work up: ing. Marie Janecká, PhD

The mobility in the Czech Republic of the European Project #Savingwater took place in several organizations and farms from Chrudim and Prague from the 7th until 13th of November. Participants from Portugal, Spain and Bulgaria shared their ideas and knowledge to learn about saving and keeping water in nature.

Training course "Saving and keeping water in nature"

According to the project program, the mobility started with a seminar on "Hydroponics in science and research at KARP". The topic was presented by Mr. Petr Zábranský (Czech University of Life Sciences, Department of Agroecology and Plant Production). The participants got to know that in early1860 the scientist Julius Von Sachs compiled the world's first recipe for a nutrient solution, after which it was possible to grow plants without soil substrate. Despite that and unfortunately hydroponics is a new way of producing many plants in agriculture in Czech as well as in Bulgaria, and especially rarely used in the field of growing ornamental plants . The lecture was very detailed and supported by lots of photos. It was very useful that the lecturer showed us what kind of equipment he used. We leart aboutt very useful some of the technics in growing plants for decorative vertical green walls, also with implementing methods of saving water which can be used in the participants´countries of this project. We learned about the new projects examining the distribution of the root system and the size of the leaf area and considered the current topic of the use of intermediate crops in field crops. The lecture finished with a practical visit to the greenhouses at the university, where we saw the hydroponic systems and discussed issues that arose during the presentation. The results of Petr Zábranský from the projects examining the distribution of the root system will be really useful for us in own future similar experiments.

In the lecture of Petr Harašta, there were introduced the different cases of run off and soil erosion in the Czech Republic. The processes also transfers plant nutrients (Nitrogen, Phosphorus) and pesticides (PPPs). Entries of PPP can also be significantly reduced to acceptable levels with appropriate mitigation measures. Thanks to the lecture we confirmed and widen our usual list of measures other ones in the scope of land management of soil erosion for example: establish hedges and artificial wetlands/ponds, build bunds and terraces with retention structures; optimized irrigation and the size of the land blocks; changing crops; controlling patterns/ working across the slope, etc. For the mitigation of PPP with the water the following measures were discussed and these may have best implementation effect in our country: moving to organic farming of appr. ¼ of the cultivated or farm areas; better awareness when using fertilizers; different ways of controlling drifts like nozzles size, boom height and others; proper technical and spraying adjustment, maintenance and cleaning of machines, safety instructions when transporting PPP, etc. – all this is included in educational events for farmers twice a month in the Czech Republic. The legal framework for water protection in the EU includes surface, groundwater, and marine waters, as well as the regulation of plant products. During the seminar, the focus was placed on reducing the risks of pesticide use, education, and training of people who apply them. Other factors important factors presented were: volume and intensity of rainfalls, soil type and properties, landscape factors (eg. slopes), soil and crop management practices, and patterns of using the land. Priorities in erosion reduction measures are related to preventing the runoff of water surfaces, retaining them in the soil, etc. We got acquainted with the specific measures and their effectiveness.
The lecture was illustrated with many photos and figures, which made the information presented even more memorable and easy to understand. The measures point towards saving water in its quantity and in its quality.

The next seminar with the topic of "Water retention in the landscape", which was presented by ing. Jiří Janoš, was held in the High school of Agriculture in Chrudim. The school director was our kind host for few days.  Mr. Janoš introduced the audience to the country's reclamation system during the communist period - canals with concrete panels accelerating the water flow. This approach led to reducing groundwater levels and hindered plant access to life-giving water. Thus, the vegetation on the shores was extremely reduced. This led to disturbances in natural water resources and problems with drought or floods. These problems affect the crops and consequently people's lives. The good thing was that the lecture offered solutions that have begun to be implemented in the Czech Republic. They are a return to the natural and historical movement of water in winding riverbeds and menadras, which slow down the flow rate and increase infiltration. These problems were mitigated through government programs that focus on returning the natural beds of local rivers, more meanders, creation of small water ponds, and construction of rugged terrain - terracing, headlands with plants, ditches along the contour of the plots and roads. The revitalization takes averagely between 3-5 years and the process starts at first with planning and with a layout accomplished by specialists. The purpose of revitalization is to optimize river systems and thus to support the infiltration of water into the soil and to support raising the groundwater level. Fine and less permeable alluvial soil profiles have a high potential to retain water and slow its runoff from the landscape. Contrary to the beliefs of 50 years ago, the plots are now being divided into smaller ones and natural hedges and belts are left between them – with trees, grass, shrubs. One other way of keeping water in place is creating of beautiful artificial lakes and fitting into nature. An additional and big benefit of that of course is bringing the wild life back, because presence of water means life! The estimated cost of the projects exceeded 400,000,000 CZK (16,000,000 euros).

Conclusion:
Firstly it was very pleasant and informative for us to see live the countryside of Czech and compare it in my mind with the rural areas for example in Bulgaria in the autumn. What we noticed was that water in Czech Republic is well kept due to cooperation between the Czech scientists, Czech government and EU. In Bulgaria due to climate changes and bad practice the fields with crops are drier most of the time and rarely very wet due to heavy rains or flooded, which of course is not good for the crop producers. I suppose it’s will be of a benefit to we follow the same way to increase water retention in our lands. The Czech rural landscape is nice and although it is maintained by humans it has its close to natural vision. There were only a little areas which were not covered with plants or crops. What we saw also was lots of rivers and lakes, approximately small arable lands with belts between them with different wild plants preserved. We were also happy to see deer and other wild birds and animals.

Using plant and animal residues and waste as an alternative source of energy (Spain)

Check the reports on EPALE (Electronic Platform for Adult Learning in Europe) in different languages: Portuguese, Spanish, Bulgarian and Czech.

The use of plant and animal residues and waste as an alternative source of energy was another partial topic to be addressed in our project as examples of good practice. The Spanish partner organization Magenta Consultoría Projects S.L.U, which prepared a very interesting and very beneficial program on the topic, undertook this task very well. The first organization visited, was Lombriastur (Grao), which specializes in the production of organic fertilizer, the transformation of composted livestock manure into humus using California earthworms. Earthworms perfectly process organic residues, which they convert into organic matter rich in humic acids and cytokinins, so they have a very positive effect on soil fertility.

Lombriastur is one of the only organizations in Asturia that has been targeting California earthworms for over 30 years. On an area of 1.5 hectares, there are 41 belts with a water-permeable foil. To obtain 300 tons of humus, it is necessary to process 1000 tons of manure. The processed oranic mass is dried in a greenhouse so that the water content of the humus does not exceed 40 %. This process takes about 5 days in summer time and up to 3 weeks in winter time. The final drying takes place using a dryer, which artificially dries the humus. The temperature of this last stage of production does not exceed 60 degrees, so as not to disturb the natural microbiology of humus. Humus can be stored for a maximum of one year in a shady place.

Thanks to the incorporation of such a good quality humus into the soil, its physical, chemical and biological properties are affected and improve its properties and form its structure suitable for plant growth, their protection against the effects of toxic substances. Humus also maintains a stable water and a temperature regime of the soils, thus allowing the development and positive impact of edaphon. Sufficient humus in the soil ensures the desired water absorption and especially along floodplains, it can reduce the risk of flooding residential areas.

Visit to Pellets Asturias (Tineo)

Pellets are a universal fuel that you can use to heat various types of buildings, such as family houses, cottages, apartment buildings, guesthouses, restaurants and other facilities. Pellets are compressed sawdust that is compressed and heat bonded. Pellets are produced by pressing waste sawdust therefore they are ecological. The best quality pellets are made of sawdust, which is stripped of bark.

In Spain, in the region of Asturias, the firm "Pellets Asturias, S.L." is only one with 6 employees in 3 working shifts, 1 a technician and an administrative worker. The entire production process is fully automated.

From an ecological point of view, the process of pellet production leads to the maximum possible use of tree biomass and it is prevented to the unused biological waste. It was very interesting to monitor the whole automated process directly thanks to the director's explanation. We were able to follow the entire production of pellets in detail and from different angles, which illustrated the view of this beneficial production activity.

Visit to eMULA project (Cabrales)

Management in the Picos de Europa National Park was very interesting for us. The eMULA company was established by the regional office for the purpose of using manure produced by breeding cows, goats and sheep. A representative of the company introduced their project to us, which is based on the traditional use and treatment of manure into the final compost form. The company buys manure from 3,000 suppliers 3 times a day and also uses wood residues from the forest mining for composting, which increases the absorption capacity. Beef cattle usually graze freely in the wild, where they unfortunately face a larger increase of the number of wild wolves, which cause considerable losses to farmers.

Dairy cattle are based on the traditional rotation of pastures near the farm. The actual production of composted manure consists in mixing all types of manure from cows, goats and sheep, so that the customer always obtains the same quality and the absorption capacity of composted manure was in maximum.

In this beautiful area, we also had the opportunity to visit a local farmer who is involved in this project. With the breeding of goats and sheep, he contributes as a manure supplier to the production of quality organic compost. It was also beneficial for us to see the production of goat and sheep cheeses in - queseria "El Cabriteru Arena de Cabrales" and the local museum of cheese production in the traditional way.

The herd at "El Cabriter" consists of about 150 Murcian goats and 250 Lacaune sheep. Their diet is carefully maintained, consisting essentially of dry fodder, mostly alfalfa and some cereals. Their food is carefully maintained, consisting essentially of dry fodder, mostly lucerne and some cereal. Animal welfare is a concern of the owners, allowing them to obtain superior quality milk with which they make their cheeses. The cheese dairy “El Cabriteru” started making cheese in 2016. After a decade as sheep and goat milk producers, they decided to take the leap and transform the milk of their goats and sheep into their own cheeses.

Being located in the region of Asturias, a region known for its variety of blue cheeses, the cheese dairy “El Cabriteru” did not limit itself to making DOP cheeses but went further by creating 3 signature cheeses, internationally awarded in 2016 (beginning of cheese production) and again in 2021 in the blue cheeses category of the “world cheese awards” contest, all its cheeses are produced with raw milk from its herd, having three different varieties: raw sheep’s milk cheese, raw goat’s milk cheese and cheese of raw sheep and goat milk.

The group was received and accompanied by the owner who, during the visit, carefully explained the whole process of raising the animals as well as the manufacture of the products, and processing of the produced manure in connection with the eMULA project.

Training course " Saving Water in the Crop Production "

ONDO is a smart farming solution created by farmers for farmers. The company’s team of agricultural experts and agronomists have very good experience in the building and integration of solutions for automated drip irrigation, precise plant nutrition and climate control for greenhouses and open fields. Together with a skilled team of experienced software and hardware specialists, they worked to create a reliable technology solution that meets the needs of farmers while keeping it easy to use.

The ONDO irrigation system is an automatic system. It consists of a water source (underground or surface), a pump, a control unit, pipes and nozzles. Equipment for the application of liquid fertilizers can also be connected to the system. This irrigation system can be used indoors (greenhouses) or outdoors (fields or gardens). It is used for row planting of vegetables, small fruits and flowers. Comaoerd to the convential irrigation systems used in Bulgaria, this system can save up to 30 % of water, reduce fertilizer consumption by up to 20 % and increase yields by up to 20 %. The system also delivered abroad eg. Greece, Romania, North Macedonia, Turkey ans Serbia. The company is constantly developing and improving the system. The current system is already the 3rd generation.

THE BOTANICAL GARDEN BORIKA

 
 

 

 

The Botanical Garden Borika was established in 2016 in the village of Borika. After graduating from the Department of Landscape Science and Environmental Protection at the Faculty of Geology and Geography, Sofia University "St. Kliment Ohridski ”, its founder, Mr. Yassen Ivanov, succeeded in making true his dream to create a place that promotes the environmental protection and let everyone learn new about nature, see rare plant species from Bulgaria and other parts of the world.


The owner of the botanical garden also showed us weeds that are invasive and unpleasant for farmers for weeds in fields and other green areas such as Japanese knotweed (Reynoutria japonica).

PAISII HILENDARSIKY UNIVERSITY

Nowadays the faculty of biology has more than 50 years of history. Annually over 1000 students study at the faculty in several bachelor courses –Biology, Biology and Chemistry, Ecology and preservation of the environment, Molecular biology and Bioinformatics, Ecology and biotechnological production and Medical biology, Biology and Physics. There is a separate laboratory for genetic engineering, within the department of plant physiology and molecular biology. Hundreds of publications (also including treatises) in Bulgaria and many other countries testify to the scientific research of the highly qualified faculty staff.


There we met a team of educators who showed interest in our project and also presented their water protection project focused on water contamination and its impact on aquatic animals. At the same time, they showed interest in cooperating and building the new ecological project. The exchange of experiences and ideas was very beneficial for both parties.

ROSE FIELDS AND DESRILLERY

40 km from Plovdiv, in the Brezovo village of Zelenikovo, the largest rose brewery on the Balkan Peninsula has been built. The distillery is 93 years old and at the time was among the most modern in this part of the world - a distillation system using French technology for the extraction of rose oil. The great experience, knowledge and striving for perfection of the owners of the then company "Shishkov and co", representing the largest producers and traders of rose oil in Bulgaria in the period from the 19th century to the mid-40s of the 20th century, were invested in its construction. century. After the nationalization, the rose brewery is managed by the former state company "Bulgarian Rose" Currently, this is the only fully preserved and authentic rosary in Bulgaria, declared a cultural monument as an architectural and technological value. There are rose fields to the destillery.
The plants bloom for two months from ½ May to ½ July. Rose leaves are collected early in the morning from 4 to 5 o'clock and until the air temperature reaches 20 degrees C, then the oil from the leaves begins to evaporate. 3 tons of rose leaves are needed to produce one liter of rose oil. Simple atmospheric distillation is used for the distillation of rose oil, whereby heat is obtained by burning fuel oil and water to coolers for condensation of water with oil droplets is obtained from an underground well. Subsequently, the heated water is freely discharged through the storage tank back into nature.

BOTANICAL GARDEN SOFIA

The University Botanic garden - Sofia was founded in 1892 by the first professor in botany Dr. Stefan Georgiev. On the inauguration day Bulgarian King Ferdinand I planted an oak (Quercus robur L.) lying a golden coin in its roots. Today the oak tree with its powerful trunk and crown gives cool shade reminding the vast oak forests covering Sofia region in the past.
Its Global Strategy for Plant Conservation mission statement “is a catalyst for working together at all levels - local, national, regional and global - to understand, conserve and use sustainably the world's immense wealth of plant diversity. The international co-operation across EU boundaries throughout a strategic partnership involving high education institutions, conservation and research organizations (botanic gardens, gene banks, universities, research institutes, non-governmental organizations) may meaningfully contribute to create a better understanding of plant diversity problems and their possible solutions. Botanical garden implement HEI PLADI project relays on a constructive cooperation and integration between five Universities, research institute and organization all providing strong expertise in the field of plant biodiversity characterization, management and conservation and in lifelong learning.

SUMMARY

The last mobility in Bulgaria has integrated the aims and objectives of our project "Saving water" very well. In this beautiful part of Bulgaria, we had the opportunity to compare approaches and technologies of organic farming, we learned about the possibilities of using arid crops and their use in the food industry. Rose plantations and their subsequent use in the pharmaceutical and cosmetic industries were a real experience for the participants, because Bulgaria has a historical tradition and value in this area. Very kind and nice mentors willingly shared their experiences and answered questions. Mutual exchange of experience is always mutually beneficial.
