Abstract

Nitrogen losses during the storage of liquid livestock manures were measured in short- and long-term model experiments (35–68/191–200 days) with cattle and pig slurries. The true nitrogen losses were strongly correlated with the storage time. They were also often higher than they were previously thought to be, even without aeration. Calculated on the ash content they ranged between 1·4 and 20·5% of the total nitrogen content after 35 days, and between 17·1 and 53·6% after 180 days. The differences did not depend on the species of animal, but on the origin of the slurries. Furthermore, they seemed to depend on the pH-value. Other alternating effects between the N-losses (ammonia volatilization) and any other parameter (e.g. mineralization rate) could not be derived from this investigation.

液态牲畜粪便贮存过程中氮的损失
采用短期和长期模型试验(35-68/191-200 d),测定了液态牲畜粪便储存过程中的氮损失。真氮损失与贮藏时间密切相关。即使在没有通风的情况下,它们也往往比之前认为的要高。根据灰分含量计算,35天后灰分占总氮含量的比例在1.4 ~ 20.5%之间,180天后灰分占总氮含量的比例在17.1 ~ 53.6%之间。这种差异并不取决于动物的种类,而是取决于浆液的来源。此外,它们似乎依赖于ph值。氮损失(氨挥发)和任何其他参数(如矿化率)之间的其他交替效应无法从本研究中得出。
