Agricultural productivity depends on the farmland quality, and a soil test can timely report a problem in crop growth conditions. Field suitability analysis helps choose the appropriate crops or decide on land use for farming. Regular soil testing is ultimately important not only for growers but can provide valuable field insights to all agribusiness players, including agri-coops, crop insurers, banks, input suppliers, or commodity traders. Nonetheless, designated laboratories describe only the current field properties. So, while analyzing soil test results for decisions on field amelioration, it’s better to combine lab reports with historical data from satellite imagery analytics.
It is the farmland analysis for multiple parameters like chemical content, toxicity, pH level, salinity, earth-dwelling biota, etc. Such tests also provide information on chemical contamination, humic or organic content, electric conductivity, cation exchange capacity, and other physical and chemical properties.
Valuable information on nutrients content allows accurate fertilization to support plant needs within precision agriculture implementations. This is why the chemical test for soil nutrients is the most common. Primarily, soil tests report on the content of nitrogen (N), phosphorus (P), and potassium (K), which are the most important nutrients for crops.
