Soil assessment builds information for improved decision in soil management. It analyzes soil conditions with regard to agriculture crop suitability requirements [such as those given by FAO <https://www.fao.org/land-water/databases-and-software/crop-information/en/>] soil fertility classes, soil erosion, and soil salinity classification [<doi:10.1002/ldr.4211>]. Suitability requirements are for crops grouped into cereal crops, nuts, legumes, fruits, vegetables, industrial crops, and root crops.
