INTER-NAW application for fertilization plan and nutrients accounting
The fertilization plan is the most important tool for managing NPK - essential nutrients in crop production. Developed in accordance with the principles of good agricultural practice, it takes into account the achievement of optimal plant yield and the reduction of the fertilization impact on the environment. In modern agriculture, advisory software is used to prepare a fertilization plan, supported by analyses of the content of NPK nutrients in the soil.
The INTER-NAW application is designed for planning fertilization of field crops with NPKMg and soil liming. Fertilizer rates are determined by the field surface balance method. The information necessary for the calculation includes crop species, expected yield, forecrop species, information on the management of by-products (harvesting/ploughing), type of manure, organic, and nutrient recycling fertilizers used, their rates and nutrient content, current soil nutrient content, and pH. Based on that information, the application determines the nutrient needs of the plant and the amount of NPK available from sources other than mineral fertilizers at a site and then calculates how many nutrients should be used in fertilizers. The use of an appropriate correction factor allows you to adjust the rates of fertilizers to the abundance of nutrients in the soil. The application allows calculating the amount of manure produced on the farm along with the NPK content, based on information about the animal stock density and its keeping. The free INTER-NAW application is used in the Polish agricultural advisory system and made available by the National Chemical and Agricultural Station at www.schr.gov.pl.
