Where in China are lateritic soils distributed? Introduction to the crops suitable for growing there
Where in China are lateritic soils distributed? What is suitable for growing there? Lateritic soil is a deep red soil formed from soil in tropical rainforests or monsoon forests under a tropical monsoon climate, through intense allitization and biological enrichment, and is named for its soil color resembling fired

In which regions of China are yellow-brown soils distributed, and what crops are suitable for growing there?
In which regions of China are yellow-brown soils distributed? What are they suitable for growing? To understand these two questions, we first need to clarify what yellow-brown soil is. Yellow-brown soil is a soil developed under subtropical evergreen broad-leaved and deciduous broad-leaved mixed forests. Its main characteristics are that the profile contains

In which regions of our country are dark brown earth soils distributed, and what crops are suitable for planting there?
Dark brown earth is a zonal soil formed under a temperate humid monsoon climate and mixed coniferous-broadleaf forests, and is an independent soil type separated from brown forest soil after the founding of China. Total K content is 15.7-19.3, the profile configuration is O-AB-Bt-C, humus accumulates in the surface layer, and the entire profile shows a medium to slightly acidic reaction, with a base saturation of 60-80%. The clay and iron-manganese contents in the middle of the profile are both higher than those of the eluvial horizons above and below it. Dark brown earth is also known as dark brown forest soil, and was once called brown podzolic soil and gray-brown earth. It was not until 1960, after the first national soil survey, that it was formally established as dark brown forest soil, namely dark brown earth.

In which regions of China are cinnamon soils distributed, and what crops are suitable for growing there?
In which regions of China are cinnamon soils distributed? What are they suitable for growing? Cinnamon soil refers to a semi-leached soil developed in well-drained terrain positions in the warm temperate semi-humid region, with weak leaching and accumulation of carbonates, and a brownish soil with secondary clayification phenomena, also known as brown forest soil.

Where in China are chernozem soils distributed, and what crops are suitable for growing on them?
Where in China are chernozem soils distributed? What are they suitable for growing? Chernozem is a soil developed under meadow steppe and steppe vegetation in temperate semi-humid and semi-arid regions. It is the more humid type among calcareous soils, named for its dark, almost black soil color, and it lies at the easternmost edge of the steppe.

Where in China are chestnut soils distributed, and what are they suitable for growing?
Chestnut soil, as the name suggests, is a chestnut-colored soil formed under a temperate semi-arid climate and the natural vegetation of dry steppe. It has a soft surface horizon and a calcic horizon somewhere within 1 m. The typical profile configuration is Ah-Bk-C. The entire profile is base-saturated,
-
Where in China are brown calcic soils distributed, and what crops are suitable for growing there?
Brown calcic soil is an arid soil that forms a transition from chestnut soil in the temperate dry steppe zone to gray desert soil in the desert zone. Its formation is dominated by the humus accumulation process and calcic process of steppe soils, and it also has some characteristics of desert soil-forming processes. It has a thin humus loamy

Where in China are alpine meadow soils distributed, and what is suitable for growing on them?
Alpine meadow soil refers to soil developed under meadow vegetation above the closed canopy line of alpine forests. In China it was once called grass felt soil. Its main features are: the surface is layered or mound-shaped due to frequent frost cracking and soil sliding; the surface layer is a soft and tough grass felt layer interwoven by grass roots. Alpine

Where in our country are alpine desert soils distributed? What is suitable for growing there?
Alpine desert soil, also called cold desert soil, has as its parent material mainly residual and slope deposits from the weathering of various rocks, and also some glacial till. Organic matter accumulation in the soil is weak, 0.4-0.6%, salt content 0.5-1.6%, and calcium carbonate accumulation is obvious. White salt efflorescence and crusts are seen on the surface, mostly

What types of calcium fertilizer are there? These soils and crops are prone to calcium deficiency
The calcium fertilizers commonly used in production at present include quicklime, containing 94%-96% calcium (CaO); hydrated lime, formed by quicklime absorbing water, containing 64%-7526 calcium; carbonate lime, made by grinding limestone and marl, whose main component is calcium carbonate; and gypsum, whose main component is calcium sulfate.
