Conceptual model of the process of applying liquid forms of mineral fertilizers to the soil

Abstract

   Materials on the formation of a conceptual model of the process of applying liquid forms of mineral fertilizers into the soil are presented. The basis of this model is the scheme of interaction of the processes in the agroecosystem of wheat at the level of the conceptual model of the resource cycle. Mineral nutrition of vegetative plants and corresponding ordering of internal relations of the system are introduced into it as an additional block. It has been found that given the specifics of scientific research and technical capabilities, it is appropriate to use the “black box” model for further consideration. This model is based on practical human activity aimed at transforming used objects by means of material, energy or informational influences. The main interacting blocks of the system of crop production process management related to the provision of vegetative plants with the main factors of their development at the levels of above-ground and root-inhabited parts of agroecosystem, spatial distribution of liquid mineral fertilizers in the zone of their application in accordance with agrotechnical requirements, including simultaneously with grain sowing, have been determined. The block of nitrogen-phosphorus nutrition for vegetative plants is presented, which is realized through the application of technological and technical support for the main methods of liquid mineral fertilizers application using a set of trailed, mounted and mounted technological machines on the basis of existing tillage and sowing working bodies. The principle of formation of machine-tractor aggregates at its initial stage on the minimum of energy costs for their production and operation is recommended. The prospect of using pneumatic systems for delivery and distribution of liquid mineral fertilizers in the zone of their application has been established.
