Features of mineral nutrition of agricultural crops

Abstract

Purpose: to analyze the experience of applying mineral and organic fertilizers on dry and irrigated lands for the main agricultural crops. The overview of scientific research results, literature sources on applying a fertilizer system in agriculture, in which nutrients necessary for agricultural crops are introduced into the soil during the most critical periods of growth and development are presented. This paper considers the use of fertilizers, taking into account the utilization rates of available forms of nitrogen, phosphorus, potassium and other elements necessary for plants from fertilizers and the root layer of the soil, clarifies the need to compensate for the removal of nutrients by the vegetative and generative parts of the crop, the rate of consumption of mineral nutrition elements by agrocenoses. The timing and methods of using organic and mineral fertilizers depend on the granulometric composition of the soil, the predecessor, the level of groundwater occurrence, the agrochemical properties of soils, the efficiency of the drainage network, weather and climatic conditions, the growth and development phase of the cultivated crop. Conclusion. The study of the works of domestic and foreign scientists on the timing, norms, types and methods of applying mineral and organic fertilizers for various agricultural crops cultivated on dry and irrigated lands, and the analysis of the studies allow us to conclude that in the conditions of digitalization of agricultural production, there is no consensus about the systems the use of mineral and organic fertilizers in the conditions of precision (precision) farming. Research in this area is promising at the present time and in the near future, especially when using modern means of diagnosing deficiencies in plant nutrients.
