Opis:
Thanks to precision farming technology, farmers are able to optimise input in the field with management-zones. Management-zones (the smallest treatment unit in the field) are defined on the basis of knowledge of local conditions, e.g. physical and chemical soil conditions, soil productivity, the presence of weeds and/or pests as well as the incidence of disease. Precision farming technology is able to materialize the requirements of sustainability and increase production. The application of precision farming technology elements go hand in hand with extra costs (the investment costs of new equipment and software; higher operating costs), simultaneously decreasing material costs (the costs of nutrition, herbicides, seeds). The aim of this study is to define motivation factors standing behind the adaptation of precision farming technology. According to 11% of interviewed farmers using precision farming technology on their farms and the research conducted, the main factors of adaptation were field quantity and the age of the farmer.
Celem badań było określenie czynników motywujących do wdrażania technologii rolnictwa precyzyjnego. Technologia rolnictwa precyzyjnego za pomocą stref zarządzania pozwala rolnikom optymalizować poziom ponoszonych nakładów. Podstawą do wyznaczenia stref zarządzania (najmniejszej jednostki pola podlegającej obróbce) jest wiedza na temat lokalnych warunków, np. fizycznych i chemicznych właściwości gleby, zachwaszczenia, występowania szkodników i chorób oraz produktywności gleby. Technologia rolnictwa precyzyjnego jest w stanie urzeczywistnić wymogi ochrony środowiska, zwiększając jednocześnie efektywność produkcji. Stosowanie elementów technologii rolnictwa precyzyjnego wiąże się z dodatkowymi kosztami w inwestowanie w nowy sprzęt i oprogramowanie, a także z wyższymi kosztami operacyjnymi, przy mniejszych wydatkach na materiały (koszt żywienia, herbicydów, nasion). Wśród ankietowanych 11% stosowało technologie rolnictwa precyzyjnego i głównym czynnikiem jej adaptacji była wielkość pola oraz wiek rolnika.

Introduction. Every farming method, whether conventional or organic, has been associated with some sort of risky behaviors leading to health issues among farmers. Substantial evidence is not available in the literature to determine whether the magnitudes of health outcomes vary between conventional and organic farmers. The study investigated whether selfreported neurological and mental health symptoms differ between conventional and organic farmers living in Indiana, USA. Materials and method. A self-reported questionnaire survey collected information from 200 conventional and 157 organic farmers of Indiana on demographic characteristics, depression and neurological symptoms. Statistical analyses were conducted to observe the differences in self-reported symptoms by groups of farmers. Results. It was observed that the conventional farmers had significantly higher age-adjusted mean neurological symptom score (p<0.01) than the organic farmers. Regression models revealed positive and significant associations of conventional farming with total (β =1.34; p=0.02), sensory (β =0.83; p=0.001) and behavioural (β =0.09; p=0.03) symptoms after accounting for age, income, education and years in farming. Positive but non-significant associations were also observed in conventional farmers with cognitive and motor symptoms, and with all subscales of depression symptoms in the adjusted models. Conclusion. The findings obtained suggest the importance of a larger study to further explain the difference in mental and neurological health effects in these two categories of farmers.

Children residing on farms with livestock may be at an increased risk for work-related injuries, compared to children who work on other commodity farms. This study characterizes children’s work tasks on Kentucky farms and assesses whether children who work on beef cattle farms are at an increased risk for farm work injuries. The results of a cohort study of children aged 5–18 years (N=999 at baseline) working on family farms in Kentucky, followed for two consecutive years after an initial enumeration five years previously, found that 70% of the children were involved in animal-related chores. Across all age groups, children on beef cattle farms devoted a greater number of hours per week to farm work, compared to children living on other commodity farms, especially during the school year. For all children in the study, working more than 180 days per year, performing farm work independently, and working on a beef cattle farm (compared to other commodity farm), increased the risk of a farm work injury. However, none of these associations were statistically significant. For male children only, the performance of work tasks independently was significantly associated with a 2.4-fold increased risk (OR = 2.41; 95% CI: 1.15–5.06; P=0.02) for a farm work injury, after controlling for days of working, age, period of data collection, and commodity type of the farm.

Opis:
Crayfish are valuable invertebrates that are constantly in great demand in all corners of the Earth. Breeding crayfish is not only large-scale production as it can also be arranged in small volumes using pools and installations of closed water supply. Cultivation of crayfish generates profit after a certain period of time, if all biotechnological norms of cultivation are considered. Cultivation of crayfish is a rather promising production, in which it is possible to obtain from 200 to 300% of stable profits during 3–4 years old. The article gives an overview of the technology of growing crayfish, taking into account the characteristics of farming in Ukraine. The basic biotechnological stages of the establishment and operation of the economy are determined, calculations of capital expenditures for the establishment of the economy are presented and the profitability of the project for the production of freshwater crayfish is determined. Cultivation of river crayfish makes it possible to obtain environmentally friendly products that can compete on the markets of Ukraine or EU countries. Also, this way of growing crayfish allows getting stocking material for release in natural reservoirs in order to restore the populations of river crayfish.

Subject and purpose of work: The purpose of the study is to evaluate the utilisation of resources necessary for agricultural production as well as their protection in farms conducting ecological production. The deliberations undertaken in this paper focus on certified farms due to their specificity and character of their production, which is compatible with the principles of sustainable development. Materials and methods: The article uses the results of research from twenty ecological farms in the Chełm-Zamość subregion of Lublin Voivodeship. The deciding factor in selecting this region was the prominent role of agricultural production in this region when compared to the other ones in the voivodeship. Results: The research results have shown that there is a lack of correlation between actions taken by producers and caring for the natural environment. Farmers displayed little awareness with regard to the use of environmental resources and assets in agricultural production. Conclusions: Running a farm aimed at ecological production is connected with the implementation of solutions that have not found application in traditional agricultural production, with obtaining a certificate and the need for training and further study. This does not, however, translate into the introduction of pro-ecological solutions in agricultural production or the farm itself. A significant share of the investigated producers did not report the need for introducing such solutions. It indicates the need for continuous broadening of knowledge and creating ecological.
Przedmiot i cel pracy: Celem opracowania jest ocena wykorzystania zasobów niezbędnych w produkcji rolniczej i ich ochrony w gospodarstwach prowadzących produkcję ekologiczną. Rozważania podjęte w artykule koncentrują się na certyfikowanych gospodarstwach rolnych z uwagi na ich specyfikę i charakter realizowanej produkcji, która sama w sobie jest zgodna z zasadami rozwoju zrównoważonego. Materiały i metody: W artykule wykorzystano wyniki badań dwudziestu gospodarstw ekologicznych z terenu podregionu chełmsko-zamojskiego województwa lubelskiego. O wyborze podregionu zdecydowała znacząca rola produkcji rolniczej w regionie na tle pozostałych w województwie. Wyniki: Uzyskane wyniki badań wskazały na brak powiązania podejmowanych przez producentów działań z dbałością o środowisko przyrodnicze. Rolnicy charakteryzowali się niewielką świadomością dotyczącą wykorzystywania zasobów i walorów środowiskowych w produkcji rolniczej. Wnioski: Prowadzenie gospodarstwa ukierunkowanego na produkcję ekologiczną jest związane z wprowadzaniem rozwiązań nie stosowanych w tradycyjnej produkcji rolniczej, uzyskaniem certyfikatu, a także potrzebą szkolenia i dokształcanie. Nie przekłada się to jednak na wprowadzanie rozwiązań proekologicznych w produkcji rolniczej i w samym gospodarstwie domowym. Znacząca część badanych producentów nie wykazała potrzeby wprowadzania takich rozwiązań. Wskazuje to na potrzebę ciągłego poszerzania wiedzy i kreowania świadomości ekologicznej.

Abstract: In recent years, Bulgarian organic agriculture is one of the sectors that is developing rapidly despite of the overall stagnation in Bulgarian agriculture and is continuously growing in farming areas as well as in number of farmers. This development is related to the suitable conditions for its adoption in our country - ecologically preserved areas; awareness and willingness of consumers to eat healthy; the realization of the benefits to the environment and rural areas; institutional support for organic farming and the good perception of organic products on international markets. Aim: Examine the condition and opportunities for development of sustainable organic farming in Bulgaria. Design / Research methods: The methods used to complete the tasks are systematic and comparative analysis, an estimated constructive method; method of statistical groupings, inductive and deductive methods of forming generalizations. Conclusions / findings: Organic farming combines the best environmental practices, biodiversity heightening, nature conservation and high production standards. At the same time, it provides public goods in terms of rural development and responds to specific consumer demand for clean and healthy products.Originality / value of the article: Organic production is an international, European and national priority. Organic farming plays an important part in the Common agricultural policy of EU for the 2014-2020 period, as well as for Bulgarian agricultural policy as a tool in regards to the sustainable management of natural resources, the preservation of food quality and safety and the humane farming means.

Opis:
Indonesia is an archipelago with a coastline of about 81,000 km and has enormous cultivation potential. The area that's the potential for aquaculture is estimated at 15.59 million hectares, consisting of 2.23 million hectares of freshwater cultivation land, 1.22 million hectares of cultivated land in brackish waters, and 12.14 million hectares of marine areas. Nowadays, only 10.1% freshwater, 40% of brackish water, and 0.01% of the marine area potentially suitable for cultivation are being used. However, land use for shrimp farming until 2017 has only reached 20% of the total potential. It is still very open to developing land for the extensification of shrimp farming. Shrimp is one of the non-oil and gas export commodities that play a crucial role. Besides the high price, shrimp also has a large market in various countries. Although the industry suffered disease outbreaks and environmental problems, Vannamei shrimp farming has recently seen a rapid expansion in Indonesia due to superior varieties and disease resistant shrimp. Vannamei shrimp is a new variety that’s some advantages, including more resistance or resistance to disease and low environmental quality, high stocking density, shorter rearing time, which is around 90-100 days per cycle. This study provides some necessary background for Vannamei shrimp farming in Indonesia. It focuses on the operating characteristics of shrimp farming in brief. Emphasis is placed on the impact of shrimp farming on the environment. Promising strategies for reducing nutrient release from shrimp farming are analyzed. Effective management measures to resolve or mitigate the adverse environmental effect of shrimp farming development have now become necessary and urgent. The sustainability of shrimp farming depends on many factors including the completeness of policies and regulations, good ecology, superior breeding and various kinds of cultivation technology and government support, advances in technology digitization and cooperation between industries shrimp farming.

Opis:
A one factor field experiment was carried out under the Beskid Niski mountain conditions in order to determine the impact level of yielding components on differences in yields of glumiferous oats cultivated in a traditional and organic system. The obtained results showed that the number of panicles had the greatest impact on differences in grain yields of oats grown using the two studied systems. The impact of this element was 61.4%, which was almost three times greater than that of the mass of a thousand grains. Of all the components of grain yield structure, the quantity of grains in a wisp had the lowest impact on the decrease in the grain yield of oats cultivated in the organic system compared to the traditional system; this impact was 18.2%. An average grain yield of oats grown in the organic system was ca. 10% lower than that of oats grown in the traditional system.
W jednoczynnikowym doświadczeniu polowym przeprowadzonym w warunkach górskich Beskidu Niskiego badano udział elementów plonowania w kształtowaniu plonu owsa oplewionego wysiewanego w systemie konwencjonalnym i ekologicznym. W wyniku badań stwierdzono, iż największy wpływ na różnice w plonie ziarna owsa oplewionego uprawianego w badanych systemach rolniczych miała liczba wiech na powierzchni 1 m2. Oddziaływanie tej cechy wynosiło 61,4% i było blisko trzykrotnie większe niż masy tysiąca ziaren. Udział liczby ziaren w wiesze w zmniejszeniu plonu ziarna owsa uprawianego w systemie ekologicznym w stosunku do konwencjonalnego był najmniejszy ze wszystkich elementów struktury plonu ziarna i wynosił 18,2%. Średni plon ziarna owsa uprawianego w warunkach górskich w systemie ekologicznym w porównaniu do systemu konwencjonalnego był mniejszy o ok. 10%.

Opis:
Aquaculture is the rational rearing of fish and other aquatic organism in man-made ponds, reservoir and cages. It is also referred to as fish farming. Aquaculture is still being practiced at subsistence level in Nigeria. It is essentially a rural, secondary and part-time activity taking place in small farms in small freshwater ponds. Aquatic organisms produced through aquaculture include fish, aquatic invertebrates, planktons and aquatic plants (seaweeds). Aquaculture came as a solution to wild stock which are been depleted, to meet the protein need of the rural population and to overcome the problems inherent in wild fisheries. The application of aquaculture has unveiled to an extent the degree to which fish farming can sustain the economy and provide the necessary protein need of the country. The management of aquaculture for fish production starts from the setting up of the farm until the ponds begin to yield. The major management problem of fishery conservation is how to control both man and the aquatic crops for the present and the future when the demand will probably be greater than now. Aquaculture is very important and is the fastest growing animal based food producing sector particularly in developing countries.

Opis:
This paper discusses the transformation from analogue to digital agriculture (smart farming) and the laws and regulations affecting the governance of agricultural data in the EU. It is argued that the current legal and policy framework in the EU is insufficient to serve the needs of responsible smart farming systems. Specifi c characteristics of farm data and patterns in farm data collection and use contribute to market failuresin agricultural data markets and hence to the insufficient provision of public goods through agriculture. The key parts of the smart farming data value chain are shaped by private contractual agreements between farmer and agricultural technology providers that do not take into account the potential negative externalities of established data flows. There is a strong rationale for a new data economy for EU agriculture, implying a greater involvement of the state in the smart farming data value chain. Interventions would be needed both to support the ecosystem for datadriven innovations in farming and to minimize the risk of new economic and social inequalities in the agriculture sector. The creation of an EU-wide farm data repository under the auspices of EU institutions andin tegrating public agricultural data with private farmers’ data subject to anonymisation and aggregation can be seen as a first step towards a new data economy for EU agriculture. Also, the Common Agricultural Policyshould be more involved in and committed to the process of the digital transformation of farming in the EU.

This present study seeks to provide a different perspective in curtailing the existing problem. The study indicated that as long as beef remains the most prominent source of red meat in Nigeria, the problem will still persist. The benefits and the challenges of ostrich farming were then discussed. The study recommends that there is a need to publicise the health benefits of ostrich meat so as to attract more consumers and players in the industry.

Considerable climate changes have been observed in the last 50 years – warming in every spatial scale (global, continental, regional and local), changes in atmospheric precipitation and several weather extremes, shrinking of cryosphere and sea level rise. The warming since the mid-20th century has predominantly been due to greenhouse gas emissions from human activities, in particular the combustion of fossil fuels, farming and other changes in land use. The paper presents the aspects of impact of climate change for farming and food security and the impact of farming for climate change in Polish and global scale. Agriculture holds a meaningful potential of reduction of greenhouse gas emissions and of carbon sequestration. It will be necessary to manage optimally advantageous changes and effectively adapt to adverse changes.

Soil erosion is a major factor leading to dams’ siltation and reducing their storage capacity. This study mapped the hot spots of soil erosion areas to predict the soil erosion/siltation in the Ghiss basin/dam (northeastern Morocco). In this context, various data has been prepared in the geographical information system for the estimation of soil erosion by integrating the universal soil loss equation (USLE). The result of this study revealed that soil loss rate ranges between 0 and 19 t∙ha−1∙yr−1. Therefore, the hot spots in the soil erosion area are to be found upstream, potentially leading to dam siltation over time. To avoid Ghiss dam siltation, we suggest terrace farming and reforestation in the soil erosion area hot spots.

Opis:
Allophane is a characteristic of Andisols whose presence can absorb soil organic matter. One of soil organic matter fractions called the “labile fraction” is currently an appropriate indicator in determining soil quality. However, there is limited information concerning the relationship between allophane and the labile fraction. This study assessed the content of allophane by selective dissolution methods and calculated the labile fraction of particulate organic matter and microbial activity related to the carbon (C) and nitrogen (N) soil cycles in organic and conventional vegetable farming systems of two depths (0–25 cm and 25–50 cm). The content of the labile fractions of C and N in organic farming systems is higher than in conventional farming systems, which is also higher in the upper layer compared to the lower layer. However, the availability of allophane in the upper layer and organic system tends to be low. Therefore, allophane has a strong negative correlation with the labile fractions of carbon and nitrogen. The results of this study estimate that phosphorus (P) sorption is higher in soils containing quite high allophane. Hence, an organic farming system that has low allophane content will result in higher P availability for plants.
