Гидронефроз - туғма патология, болаларда жомча-сийдик найи сегмента тусиги билан пайдо бўлади. Учраш даражаси 1:500, 1:800 нисбатта учрайди. ( Коварский С.Л., Захаров А.И. Вазопексия при гидронефроза у детей. Детская хирургия 2016; (4); 175’7-)-Болаларда туғма гидронефрозни кўпинча туғма сабаблар чақиради, жомча сийдик найи сегмента стенози, клапани, букилиши, сийдик найини жом юкоридан чиқиши, битишма ва аберант кўшимча қон томирлар билан босиши.

In this work, cotton gin waste – CGW-phosphorus composts based on the waste of CGW and deposit Guliob phosphorite (GPh) were prepared, with wide mass ratios of CGW : GPh = 80 : 20; 75:25; 70 : 30; 65:35; 60 : 40; 55:45; 50 : 50; 45:55 and 40:60. The kinetics of the conversion of indigestible forms of phosphorus and calcium into a form assimilable for plants in poor GPh has been studied. It has been shown that an increase in the mass fraction of phosphate raw materials in relation to CGW leads to an increase in the content of the total form of phosphorus pentoxide in composts, but to a decrease in the relative content of the assimilable form of P2O5 and CaO. The longer the exposure time of CGW-phosphorite composts, the more forms of phosphorus and calcium digestible for plants.
