Results of preliminary studies on the production and agrucultural crops research of 'JAMB-70' polycomponent mineral fertilizers

摘要

The information on monitoring of the soil covering of the South Kazakhstan Region, mineral fertilizers and fertilizers in the Republic of Kazakhstan, neighboring and far abroad countries is provided. Materials on obtaining various types of mineral fertilizers by sulfuric acid extraction of phosphate raw materials and simple, mixed and liquid complex fertilizers are given. Materials on the production of prolonged action complex mixed mineral fertilizers on a pilot plant with a productivity of 500 kg per hour and their field testing on soil covering of the rural district of Zhaskeshu, Borsyksai LLP of the Tulkibas District, Mart LLP of Ordabasy District and Zhantas farm household agricultural crops are presented. The data on the production of variouscrops depending on the ratio of charge materials of "JAMB-70" multicomponent mineral fertilizers of prolonged action containing humectants, humates and minor elements are given. The possibility of obtaining polycomponent mineral fertilizers without preliminary chemical treatment of the phosphate material is shown. The benefits of obtaining "JAMB-70" fertilizer mixture in comparison with existing methods on the basis of the developed and offered for implementation technology of production of complex mixed polycomponent mineral fertilizers of prolonged action "JAMB-70" containing humectants, humates and microfertilizers are presented.
