THE IMPORTANCE OF MOBILE PHOSPHATES IN THE SOIL AND THE EFFECT OF NITROGEN FERTILIZERS ON INCREASING THE MOBILITY OF PHOSPHORUS UNDER DIFFERENT AVAILABILITY OF TYPICAL SEROZEMS
Journal Title: International scientific journal Science and Innovation - Year 2023, Vol 2, Issue 9
Abstract
The article presents data on the study of the content of mobile phosphorus in the soil, extracted by ammonium carbonate, dated in the early periods of the growing season, the beginning of the year, April-May, and the later months in autumn. The researchers found that the use of nitrogen fertilizers (urea), under cotton and prickly artichoke, especially ammonium sulfate in relation to ammonium nitrate and calcium nitrite, contribute to an increase in mobile phosphates in the soil due to the mobilization of the first groups of phosphates. Accordingly, the mobile phosphates extracted by ammonium carbonate solution, when ammonium sulfate and urea are added to the plants we study, increase with this nutrition element to a greater extent on medium-rich than on low-rich soil. Thus, the use of urea and especially ammonium sulfate, in comparison with other forms of nitrogen fertilizers, especially in comparison with low-availability phosphorus in the soil, enhances the growth, development and productivity of cotton and prickly artichoke, as well as biologically active substances (rutin, luteolin) in their tissues
