Hisoblash: S = 0,5 ga maydonga ega bo'lgan uchastkada unumdor tuproq qatlamining hajmi va vazni qo’yidagiga teng bo'ladi:
, .
Moddiy muvozanat tenglamasiga muvofiq cho'kindilarning massasini aniqlash uchun avvalo bir kilogramm cho'kindiga mis va nitratlarning konsentratsiyasini topishingiz kerak:

.
Mis va nitratlar uchun ruxsat etilgan maksimal cho'kindi massasini aniqlash uchun aralashtirishdan keyin ularning har birining kontsentratsiyasini maksimal ruxsat etilgan kontsentratsiyasiga (REK) teng deb olamiz.

.
Hisob-kitoblar shuni ko'rsatadiki, mis va nitratlar uchun ruxsat etilgan cho’kma massasi har xil, shuning uchun loyni joylashtirish uchun siz yotqizilgan cho’kma massasining minimal qiymatini tanlashingiz kerak, ya'ni.
.
Mis uchun hisoblangan va 804,8 tonnaga teng bo'lgan cho'kindi massasini tanlashda aralashgandan keyin cho'kindagi nitratlarning konsentratsiyasi quyidagicha bo'ladi:
,
ya’ni, ruxsat etilgan kontsentratsiyadan kam.
Maydonga joylashtirish uchun mo'ljallangan maksimal hajm ( ) va cho'kindi balandligi ( ) quyidagicha bo'ladi:
, .
Vazifa. Guruh ro'yxati tartib raqamga ko'ra tanlangan variant bo'yicha S hududda m massasini, hajmini V va balandligi h ni, shuningdek S hududida qishloq xo'jaligi ob'ekti uchun o'g'it sifatida ishlatilishi mumkin bo'lgan barcha tarkibiy qismlarning kontsentratsiyasini aniqlang.
