What Is a Soil Map?
Soil map [1] is a map reflecting the distribution and characteristics of different soils. Soil maps have important application values in planning and guiding agricultural production, evaluating land resources, correctly selecting agricultural land, and planning the layout of agricultural enterprises. Soil maps represent thematic maps of various soil types, spatial distribution of soil physical and chemical properties, soil erosion, soil improvement zoning, and soil zoning. [2]

- Soil map [1] is a map reflecting the distribution and characteristics of different soils. Soil maps have important application values in planning and guiding agricultural production, evaluating land resources, correctly selecting agricultural land, and planning the layout of agricultural enterprises. Soil maps represent thematic maps of various soil types, spatial distribution of soil physical and chemical properties, soil erosion, soil improvement zoning, and soil zoning. [2]
- Soil maps are divided into two types: ordinary soil maps and specialized soil maps. The former includes soil type maps, soil zoning maps, etc., which are comprehensive, comprehensive, and versatile, and are the most basic map types in the soil map; the latter focuses on reflecting certain characteristics of the soil or the content required by a particular service object , Such as forest soil maps, engineering soil maps, soil nutrient maps, soil pH maps, soil infiltration maps, soil salinity maps, and soil erosion maps. Soil maps generally refer to soil type maps. The basic content of soil maps is to indicate the epigenetic categories of soil coversoils, subclasses, soil genera (groups), geographical distribution of soil species and varieties, and the mechanical composition and soil formation of soil Parentage. The soil map should reflect the horizontal and vertical zonality of the soil genesis, as well as the geographical distribution of the cultivated soil. Large-scale soil maps ( 1: 50,000) should indicate the quality, soil type, and variety of individual agricultural land for land planning and estimation of soil conditions. Medium-scale soil maps (1: 50,000 to 1: 500,000) should be reflected to the soil genus level and used for watershed planning and estimation of land resources in the region. The small-scale soil map (<1: 1 million) mainly reflects the geographical laws of the soil and represents soil types and subtypes. The soil zoning map is a regional zoning based on the combination of soil formation conditions, distribution rules, and agricultural production characteristics. It is directly based on soil genetics and serves agricultural production. Soil maps have important application values in planning and guiding agricultural production, evaluating land resources, correctly selecting agricultural land, and planning the layout of agricultural enterprises.
