In this study, an overview is made and a comparative analysis of articles, reports materials dealing with organic farming LWC, in the period 1970 to 2021 performed. After analysing literature, following conclusions are made: Cereals occupy particularly important place farming, main advantages their cultivation easy techniques, relatively mechanical weed control, disease control through rational crop rotation, opportunities for biological major pests. The soils better structured than those conventional agriculture. Organic practices related improving soil properties, including addition matter soil, increasing population earthworms, biodiversity, fertility more. Biological management provides more stable structure. larger pores observed have beneficial effect on physical properties such as water flow capacity. greater porosity good habitat microorganisms. contributes creating systems traditionally been based rotation. aim achieve balance between crops that reduce restore fertility. Crop rotation tool integrates maintenance development various aspects plant production systems. Specialised selection programmes varieties suitable too few due small number users high costs. most common practise includes testing suitability conditions, propagation distribution best sector. Sowing norms directly sowing density, well nutrient area each plant. Changing rates also excellent method controlling weeding fields. Concerning yields from agriculture, farms less productive ones productivity lower. But if environmental variables taken into account, show same or higher efficiency. A problem facing future protection fields pollution by genetically modified organisms. An option protecting maintain buffer zone farm neighbouring prevent accidental contamination GMOs.
