Dataset of chemical and Near-Infrared spectroscopy measurements of fresh and dried poultry and cattle manure

The dataset consists of 332 manure samples from poultry and cattle origin, sampled in farms located in major regions of livestock production in mainland France and Reunion Island. The samples were analysed for seven chemical properties following conventional laboratory methods : dry matter (DM), total ammonium nitrogen (NH4), total nitrogen (N), phosphorus (P2O5), calcium (CaO), magnesium (MgO) and potassium (K2O). Near-Infrared (NIR) spectra were acquired with three spectrometers on fresh homogenized and dried ground samples and standardized by PDS algorithm.

本数据集包含332份源自家禽与牛的粪便样本，采集自法国本土及留尼汪岛的主要畜牧生产区域内的养殖场。
按照常规实验室分析方法，对样本的7项化学性质进行了检测：干物质（dry matter, DM）、总铵态氮（total ammonium nitrogen, NH₄）、总氮（total nitrogen, N）、五氧化二磷（phosphorus, P₂O₅）、氧化钙（calcium, CaO）、氧化镁（magnesium, MgO）以及氧化钾（potassium, K₂O）。
通过三台光谱仪采集新鲜均质样本与干燥磨碎样本的近红外光谱（Near-Infrared, NIR），并采用PDS算法完成标准化处理。
