最大限度地发挥牲畜粪肥和无机肥的效益是经济上和环境上所期望的。已经发现在牧草生产中,奶牛厩液的氮肥有效成分变化很大。在牧草生长季节厩液的氮肥有效成分可变性可能是由于通过挥发或反硝化作用使氮受损失。反硝化作用是在无机氮肥和家畜厩液使用后发现的。当含硝酸盐土壤温度大于8℃时,厌氧微生物的小区扩展,反硝化作 The benefits of maximizing livestock manure and inorganic fertilizers are economically and environmentally desirable. It has been found that the effective components of nitrogenous fertilizer in dairy cattle manure vary greatly in pasture production. The variability in the active nitrogen of the manure during the forage growing season may be due to the loss of nitrogen through volatilization or denitrification. Denitrification is found after the use of inorganic nitrogen and livestock stables. When the nitrate-containing soil temperature is greater than 8 ℃, anaerobic microbial community expansion, denitrification
