THE REACTION OF THE YOUNG CORN PLANTS TO THE NITROGEN, PHOSPHORUS AND POTASSIUM FERTILIZERS APPLIED IN SOIL

The test of fertilization with nitrogen, phosphorus and potassium of the plants, the test plants: corn hybrid OPH-98,-the young plants in the vegetation pots show: all three nutritive elements influence upon the growth and the content of these elements in above ground portion of the dry matter of plant; the nutritive effect of these elements is lower in the soil as compared to the quartz sand; the quantitative relation of these elements in the above ground part of plant dry matter is dependent upon the fertilization; the deremined nitrogen cycle in thti plants is not in concordance with ammonia and nitrate nitrogen in soil: the amounts of nutrients phosphorus and potassium applied in soil are confirmed by AL method of soil analysis
