METHOD FOR PREDICTION OF CONTENT OF MINERAL FORMS OF NITROGEN IN SOIL UNDER SPRING GRAIN CROPS

摘要

Method for prediction of content of mineral forms of nitrogen in soil under spring grain crops includes determination of content of mineral nitrogen in soil by optical properties. Content of mineral forms of nitrogen in soil and determination of needed and timely feeding are calculated by levels of regression. At that dose for bringing in mineral nitrogen is determined by coordinates of color of culture leaves at photographs made in field in digital form.
