In developed countries, the ideas of ecological agricultural production, continuous cycle, and waste-free production technologies have gained popularity. The effect from the production and consumption of ecological agricultural products is determined by the least harm to the environment, increasing the competitiveness of products, and receiving additional profit from increasing prices for higher quality products. The production of organically safe products is based on the principle of biologization, i.e., the widespread use of biological preparations, a high proportion of legumes (sources of nitrogen), and avoiding chemical plant protection products, transgenic plants, and genetically modified organisms (GMOs). This study aims to increase the productivity of safflower and improve the physicochemical and biological indicators of dark chestnut soils through the use of biologized technologies in the organic farming system. Standard methods for assessment and statistical analysis of physical and chemical parameters of soils were carried out in zone 1 of West Kazakhstan. This made it possible to identify the most optimal technology for the cultivation of safflower. The study results showed that under the influence of the phytomeliorative action of safflower in the 0–20 cm layer of dark chestnut soils, one could note an increase in the content of nitrate nitrogen by 5.95%, an increase in the content of mobile phosphorus by 5.22%, and soil loosening by 0.010 g/cm3, with the structure of the soil being 64.43%. Strong biological activity of the soil was established by the crops of safflower. The highest yield of safflower oil about 0.23 t/ha with an oil content of 30.1% was obtained using the biologized technology option. The use of biological technology, along with biological yields, increases oil yield by 0.06 t/ha or 28.06%.

Internationalization of farms involved in agricultural production requires ensuring appropriate quality of products, compliant with requirements of specific markets. Consumers from developed countries more and more often draw attention to the origin of food products and confirmation that they were produced in accordance with recognized environmental standards, while simultaneously respecting human rights. The aim of this research study was to assess the extent of changes in production technology and in the management system under conditions of implementing the GLOBAL G.A.P. system on selected fruit and vegetable farms associated in producer groups. The second aim was to evaluate the quantity of sold products along with specific certificates. The research was conducted in 2016; 91 vegetable farms and 71 fruit farms were studied. The results of the conducted research show that implementation of standards required creation of a quality management system on all the studied farms. The implementation of standards required creation of procedures for production management as well as the traceability system. The implementation of standards caused the necessity to change the infrastructure for storage and use of plant protection products and fertilizers, as well as infrastructure improving workers’ social conditions. The study results indicate that changes associated with the implementation of the GLOBAL G.A.P. standard applied more to vegetable farms than fruit farms. The implementation of the GLOBAL G.A.P. standard significantly increased producers’ chances to introduce products on the market through commercial networks and by selling them to foreign markets.

Agriculture is one of the basic human activities. This activity, however, also had a negative impact on the environment. For decades, organic farming, understood as a system of management of sustainable crop production and livestock within the farm, has been developing. Constantly increases both the number of organic producers and the area of organic farming. Organic agriculture is currently supported with success through the development of the law in this area, both on the world market, European and Polish. Thanks to regulations gradually entered into force a consumer acquiring products referred to as organic is convinced that they are free from contamination, such as residues of plant protection products and hormones, and when their production not used chemical fertilizers and genetically modified organisms.

The changes of the soil’s humus soil within the rural areas are investigated for the organic farming system. The most significant impact of organic agriculture on humus content over 55% was observed on soddy podzolic soils (V>75%), the lowest –7,5% on typical chernozem (V≈16%). Changes in the qualitative composition of humus for the introduction of various types of organic substrates are analyzed.

While there is growing recognition of the positive role played by organic farming in the reduction of the negative externalities due to conventional agriculture, there is uncertainty about the effect of the latter on the economic performance of the farms. In this scenario, the present paper aims at investigating the effect of organic farming on technical efficiency in Italian olive farms. A cross-section dataset was analyzed through the stochastic frontier function, where the adoption of organic farming was explicitly modeled. Then, to obtain an unbiased estimate of the impact of organic farming on technical efficiency, a propensity score matching method was implemented. The findings reveal that organic farming increases technical efficiency in Italian olive farms by approximately 10%. The highest impact of organic farming is observed in small farms. As for the propensity to become organic, we found that the production and the direct sales of a higher quality of gross marketable output, as well as the intensity of labor and machines, increase the probability to adopt organic farming. Conversely, farm localization, the availability of family labor, and financial capital discourage conversion to the organic farming system.
