16;16;16;5 MARKALI NPK O‘G‘ITINING FIZIK KIMYOVIY XUSUSIYATLARINI LABORATORIYA SHARTLARIDA O‘RGANISH
Kalit so‘zlar:
NPK, ammafos, karbamid, KCl, NH4SO4, azot, fosfor, kaliy, laboratoriya, eruvchanlik.Abstrak
Ushbu maqolada 16;16;16;5 markali NPK o‘g‘itining fizik-kimyoviy xususiyatlari o‘rganildi, laboratoriya sharoitida ammafos, karbamid, kaliy xlorid va ammoniy sulfatlari maydalanib aralashtirildi va kerakli kattalikda donador o‘g‘itlar olindi. Laboratoriya sharoitida olingan bu markali NPK granulalarining ko'rinishi, ichki tuzilishi va sifati baholandi. Xususan, NPK granulalarining sirt tuzilishi, zarracha shakli va intergranular yopishish darajasi (aglomeratsiya) Euromex Microscopen B. V. mikroskop yordamida vizual va mikroskopik tahlil qilindi.
