Research On Fertilization Of Soil Testing And NPK Fertilizer Development And Production Of Dedicated

This project is mainly for agriculture in Heilongjiang Province of the different economic zones of natural soil conditions and planting crops, the choice of soil type is black soil and meadow soil; crops are rice, corn, soybean, soil nutrient analysis and study of crop nutrient needs. The main method is in accordance with international "IPI" the Organization of the analytical methods provided for by sampling a large area multi-point detection, the establishment of arable land under different conditions of soil nutrient variation of nutrient databases and management information systems, of different soil cultivation system and a variety of internal cycle of nutrients and changes in the characteristics of the law; the application of GIS / GPS system for a variety of agricultural systems migration of nutrients, soil nutrient status of a variety of system characteristics and changes in position description and information graphics management, the establishment of balanced fertilization management system, establish a rational fertilization of farmland software. Information database through the use of data to determine the utilization of chemical fertilizers obstruct the limiting factor to improve and overcome the limiting factors to identify the best way. Eventually be applied to screen out the use of different crops in different soil and fertilizer compound fertilizer efficient formula, through the technology of production, and fertilizer products used in Daejeon display model tests to determine the economic benefits yielded.
