Name (also credit rating) for the classification of the quality (creditworthiness) of agricultural objects under consideration. This can include certain plant traits, fruit condition or the nature of floors affect. In the latter, the soil composition and signs of aging are taken into account taking into account the groundwater and climatic conditions classified. Criteria for the creditworthiness are, for example, cultivation restrictions (main fruits), processing ability, thickness, subsoil, crumb cohesion, absorption (absorption capacity) and moisture (see also under water discharge and Water storage capacity ), and melioration effort (measures to increase the value of the soil). The soils are rated on a scale from 1 to 100, under 18 a soil is no longer usable for agriculture.
With a plant rating, the plant characteristics with the main points habitus (Growth), saplings / shoots, leaf characteristics, flower, fragrance and fruit characteristics, each with sub-items with partially specified information (e.g. leaf / top surface are hairy, glandular, glabrous, matt, shiny, woolly, frosted). Another criterion is the number of insects living on a plant. Protective and maintenance measures such as the use of spray agents or fertilizer be determined. Furthermore, this is a selection criterion for one vegetative propagation provided plants. Large-scale soil ratings in viticulture may also be based on the satellite NDVI (Normalized Differenced Vegetation Index), which is often the case with precision viticulture is common.
