COMPLEX FERTILIZERS WITH MICROELEMENTS FOR MAIZE

摘要

The invention relates to production of mineral fertilizers, in particular, to production by chemical production units of complex fertilizers to be used in agriculture for cultivation of maize. Various compositions of complex fertilizers with microelement additions are presented that are intended for basal fertilizing before seeding and for foliar application to vegetating maize plants. Their agrochemical efficiency is described, the data have been obtained during field tests on sod-podzolic, light-loam and loose sandy-clay soils. Data are given on the effect of the complex fertilizes with modifying additives in accordance with the invention on the yield capacity and quality of maize herbage and grains. It has been found that application of the complex fertilizes with modifying additives both for basal fertilizing before seeding and for foliar application to vegetating plants increases maize herbage and grain yielding capacity, and at the same time improves quality indicators of products (yield of dry mass, feed units, raw protein and provision of a feed unit with digestible protein).
