Term (also bonitisation) for the quality classification (creditworthiness) of agricultural objects of observation. In agriculture, this includes all observations of the phenotype of a plant. This can relate to plant characteristics, fruit condition or soil quality. In the latter case, soil composition and ageing phenomena are classified, taking into account the influencing groundwater and climatic conditions. Criteria for creditworthiness are cultivation restriction (main crops), workability, thickness, subsoil, cohesion of the topsoil, adsorption (absorption capacity) and moisture, as well as melioration effort (measures to increase the value of the soil). The soils are rated on a scale of 1 to 100; below 18, a soil is no longer considered suitable for agriculture.
Using the encyclopaedia is not only time-saving, but also extremely convenient. What's more, the information is always up to date.
