肥料

Farmers are scrimping on fertilisers to replenish the soils they plunder

有些农民在施肥方面精打细算，为的是可以给他们吞占来的土地上再添加肥料

Data of nutrient contents in diets and in slurries were obtain by feeding experiment and analyzed.

通过饲养试验得到摄入养分含量和猪粪便中肥料成分含量的实测数据，对其进行统计分析。

His experiment is to build mathematical model in order to estimate fertilizer value of raw swine slurries based on nutrients intake.

本试验旨在建立基于摄入养分含量的数学模型，用来预测猪粪便肥料成分含量。
