THE TRAIN-METHODS OF DEFINITION OF SECURITY OF VEGETABLE CULTURES NUTRITION ELEMENTS
Abstract
Methods of definition of mineral connections of nitrogen, phosphorus and potassium in plants are founded on their extraction from weight crude vegetative weight of 0,2 M by a solution of an acetic acid at a parity of weight of a plant and a solution 1:10 with the subsequent definition of nitrogen of nitrates of ammonium and phosphorus - in the form of the painted connections, potassium - on an ardent photometer.
