Database of hyperspectral images of phosphorus in soil.

The database is made up of the images associated with the hyperspectral cube of each sample, and four tables: the first describes the properties of the soil used to obtain the mixtures, the second the composition of the fertilizer used, the third describes the soil-fertilizer ratio to make up the samples, and the fourth was the laboratory analysis of the total phosphorus content of the analyzed samples. Hyperspectral images can be used to quantify the concentration of total phosphorus in soil samples. 152 soil samples were prepared, and a hyperspectral cube made up of 145 images in the VIS-NIR bands, between 420 and 1000 nm, was obtained from each of them. The images obtained were taken with the Bayspec OCIF Series hyperspectral camera, in push-broom function, using a platform that includes an illumination system that offers a continuous spectrum in the range of interest. The samples were prepared with a soil from the Santander de Quilichao region, Cauca, Colombia, and mixed with known concentrations of P2O5 fertilizer, so that a total mass of 50 g was obtained. Each sample was deposited in a round black plastic container, 6 cm in diameter and a depth of 1 cm. The soil samples were analyzed in the laboratory to establish the concentration of total phosphorus.本数据库包含与每个样本的高光谱立方体（hyperspectral cube）相关联的图像，以及四张表格：第一张表格说明制备混合样本所用土壤的属性，第二张表格记载所用肥料的组分，第三张表格描述配制样本时的土壤-肥料配比，第四张表格则为各待测样本总磷含量的实验室分析结果。 高光谱图像可用于量化土壤样本中的总磷浓度。本次研究共制备152份土壤样本，每一样本均获取了由可见光-近红外（VIS-NIR）波段（420~1000 nm）下的145张图像组成的高光谱立方体。所采集图像由Bayspec OCIF系列高光谱相机以推扫式（push-broom）成像模式拍摄，搭载的照明系统可在目标波段范围内提供连续光谱。 样本采用哥伦比亚考卡省桑坦德德基利查奥地区的土壤制备，并与已知浓度的五氧化二磷（P2O5）肥料混合，最终每份样本总质量为50 g。每份样本被置于直径6 cm、深度1 cm的圆形黑色塑料容器中。所有土壤样本均经实验室分析以确定其总磷浓度。
