Laws of Organic Farming

The level of soil fertility and crop yields is determined by how far the laws of agriculture are enforced. The Law of Return of Substances (J. Liebig, 1840). According to this law, mineral and organic nutrients that have been alienated from the crop or lost as a result of agricultural use must be returned to the soil in an equivalent amount. The law of minimum, optimum and maximum, or the law of limiting factors, is closely linked to the law of return. of plants depends on the factor or nutrient that is at a minimum when insufficient value of one factor, for example, temperature, limits the flow of nutrients into the plant, worsening The flow of physiological and biochemical processes in plants.The law of irreplaceability and equivalence of factors (moisture, elements of nutrition, air, heat, light, etc.) – none of the factors of plant growth can be replaced by another, even close in properties and effects on the plant.The law of optimal combination all factors of growth and development of plants (moisture, nutrients, air, heat, light) .The law of combined development of phytocenoses and places of cultivation – not only an individual organism, closely related to the place of cultivation, but also the vegetation cover as a whole The law of the complex action of all factors of plant growth and development, which is based on the theory of nutrition and photosynthesis.The law of constant increase of soil fertility – provided the return to the soil of nutrients and the involvement of significant elements of biogenic soil. This is the basic law that applies under all laws.
