Arable land is divided into good, medium, and bad quality land Good Quality Land - (fertile land) the following quality classes are distinguished, denoted by the symbols I, II, III (a).



Arable land is divided into good, medium, and bad quality land. Good Quality Land - (fertile land) the following quality classes are distinguished, denoted by the symbols I, II, III (a).

Class I - Arable soils of the best quality Class I soils are always found in good physiographic conditions. These soils are structured, abundant with nutritive components, easy to cultivate, warm, active, pervious and airy, but also sufficiently humid, non-encrusting and containing sweet humus to a well-developed humus level, as well as displaying good water and air proportions, and not requiring drainage. These soils are suitable for all types of plant production. They form part of very good and good wheat complexes. The following types of arable land are classified here: Chernozemic soils, silt alluvial soils, humic alluvial soils, some black soils, intrazonal soils, and loess-formed brown soils. Class II - Arable soils of very good quality Class II soils show similar properties as Class I soils, but they are found in slightly worse land-surface conditions. They display worse water proportions, are less pervious, less airy, and sometimes slightly more difficult to cultivate. They are either drained or do not require drainage. They are suitable for the same type of plant production as Class I soils, but under average agricultural conditions the crop yield is lower. This Class contains the same types of soil as Class I, plus some lessive soils and brown soils. Class III (a) - Arable soils of medium-good quality Class III (a) soils are characterised by a more reduced range of crop plants, due to their physical and chemical properties, as well as physiographical conditions, especially all water proportions are worse than those in Class I and Class II soils. The majority of soils in this Class show clear degradation symptoms. Some Class III (a) soils can also be more difficult to cultivate. These soils can usually be classified to good quality wheat soil complexes. The following types are classified as Class III (a) soils: brown and lessive soils, degraded Chernozemic soils, sandy alluvial soils, and some intrazonal soils, as well as peat-muck and peat soils not requiring drainage (or drained).
