Carbon and nitrogen dynamics and stabilization time of a swine manure-straw compost
猪粪秸秆高温堆肥过程中碳氮转化特征与堆肥周期探讨

An experiment was conducted to study the C and N dynamics and stabilization time of a swine manure-straw compost.Fresh swine manure and wheat straw were mixed at a 7:1 ratio and then composted in a self-built,static forced-air composting box (90 L).The outer wall of the box was insulated with 8cm plastic foam.Temperature was monitored every day and compost samples were taken 0,4,8,12,17,and 23 d after the start of the experiment.Ammonium (NH+4-N),nitrate (NO-3-N),organic N (Org-N),water-soluble organic C,or...
