Abstract
Alkalinity losses resulting from nitrification in laboratory mud‐water systems treated with compounds used for ammonium fertilizers agreed with stoichiometric calculations of potential alkalinity losses. Each milligram/liter of nitrogenous compound can destroy the following amounts of total alkalinity (in milligrams/liter as CaCO3): NH4NO3, 1.25; (NH4)2SO4, 1.52; (NH4)2HPO4, 1.14; NH4H2PO4, 0.87; urea, 1.67: Poly N (10–34‐0 liquid fertilizer), 0.72. These data may be used to estimate the amounts of agricultural limestone required to neutralize the maximum acidity that could result from complete nitrification of ammonium applied to ponds in these fertilizers. Amounts of limestone needed to neutralize the maximum acidity possible from other nitrogenous fertilizers may be calculated from stoichiometric relationships.This publication has 0 references indexed in Scilit:
