Selected Properties of Soils for Long-Term Use in Organic Farming

Abstract

The goal of organic farming with respect to plant production is to create high-quality products while minimizing human impacts. The aim of this paper was to assess soil properties in selected organic farms in terms of the achievement of general and specific objectives of organic farming. Fifty five (55) organic farms were selected for the research; twenty five (25) of those farms additionally had conventional animal production with cattle breeding. Soil samples were collected from each farm and, the following parameters, deciding about the suitability for agriculture were determined: pH, content of organic carbon, available phosphorus and potassium, mineral nitrogen, and Total nitrogen content. The content of available phosphorus and mineral nitrogen was very low or low in most of the studied soils, which can lead to disturbance of homeostasis of agroecosystems. Potassium content in these soils was high. The properties of the studied soils indicate a high risk of chemical and biological degradation. Without implementing actions that control the pH and increase the content of nitrogen and phosphorus elements, the degradation will increase. Soil properties in the group of farms with animal production were more beneficial from the point of view of crop production, compared with farms that do not breed animals.

The Impact of a Controlled-Release Fertilizer on Greenhouse Gas Emissions and the Efficiency of the Production of Chinese Cabbage

“…Reducing the total amount of elements introduced into the soil environment raises the risk of reducing yields, which agricultural producers fear [7]. Liang [37] has indicated the high effectiveness of subsidizing technological innovations in agricultural production in terms of limiting the negative impact on the environment [46][47][48][49][50][51][52][53][54]. Linking subsidies with pro-environmental measures in agriculture can bring positive effects in reducing GHG emissions.…”

Inconsistencies in the Dynamics of Sustainable Development Dimensions in Central and Eastern European Countries

“…(1) Organic farming Organic farming represents one important potential contributor to environmental, economic, and social sustainability [40] (p. 1), and is often perceived to have beneficial impacts on the environment, compared to conventional farming [41][42][43][44][45]. Thus, it is gaining recognition as a relatively friendly production system and, as Hansen et al [46] (p. 11) remarked, in general, the risk of harmful environmental effects is lower with organic than with conventional farming methods, though not necessarily so.…”

Renewable Energy Promotion Instruments Used by Innovation Brokers in a Technology Transfer Network. Case Study of the Enterprise Europe Network

“…Among the different types of involvement of innovation brokers [10,11], their interaction in collaborative projects represents one of their more complex, rich, and engaged roles. In addition to developing and supporting the partnership, they engage in co-creative innovation activities with colleagues, in a process of greater co-creation and joint development [12][13][14][15][16][17][18][19].…”
