Sustainable farming is one of the priority goals of the "4 per 1000" concept with regard to the preservation of soil fertility and carbon sequestration. This paper presents a study on the use of a mixture of cover crops of self-grown oats ( L.) and sown white mustard ( L.) in organic farming under the agroecological conditions of Serbia. The main objective was to identify sensitive carbon pools (microbial carbon and nitrogen, basal respiration and a number of specific groups of soil microorganisms) in organic farming with and without cover crops. The inclusion of a mixture of white mustard and self-grown oats as a cover crop led to a significantly increased biogenity of the soil compared to a control after only a few years of investigation. The number of microorganisms, soil respiration and microbial biomass carbon were significantly higher in the cover crop treatment compared to the control soil on an organic farm in Serbia. This is the first study in Serbia to investigate the effect of self-grown oats as a cover crop. Further research will incorporate a wider range of variables and factors in order to develop a sustainable and effective site-specific system for organic crop production in Serbia.
就保持土壤肥力和碳固存而言，可持续农业是“千分之四”概念的优先目标之一。本文介绍了在塞尔维亚农业生态条件下，有机农业中使用自种燕麦（L.）和播种白芥（L.）的覆盖作物混合物的一项研究。主要目标是确定有机农业中有和没有覆盖作物时的敏感碳库（微生物碳和氮、基础呼吸以及若干特定土壤微生物组）。经过仅数年的调查，与对照相比，将白芥和自种燕麦的混合物作为覆盖作物纳入导致土壤生物活性显著增加。在塞尔维亚的一个有机农场，与对照土壤相比，覆盖作物处理中的微生物数量、土壤呼吸和微生物生物量碳显著更高。这是塞尔维亚第一项研究自种燕麦作为覆盖作物效果的研究。进一步的研究将纳入更广泛的变量和因素，以便为塞尔维亚的有机作物生产开发一个可持续且有效的因地制宜系统。
