In which regions of our country is red loam distributed, and what crops is it suitable for growing?
Red loam is a zonal soil formed under the hot and humid climate of the southern subtropics through a relatively strong ferrallitic process. Its intensity of ferrallitization, soil nutrients and acidity fall between those of red earth and lateritic red earth. The regions where red loam is distributed and what crops it is suitable for growing are what many

Which regions of China have red soil and yellow soil distributed, and what crops are suitable for planting there?
Red soil and yellow soil are two different types of soil. Red soil, yellow soil and lateritic soil can be collectively called ferralsols. Below we will look at which regions of China red soil and yellow soil are respectively distributed in, and what crops they are suitable for planting. 1. The distribution regions of red soil and suitable planting

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

Where in China is brown earth distributed, and what is it suitable for growing?
Brown earth is a widely distributed soil type in northern China and is an important forest and agricultural soil. So, where exactly in China is brown earth distributed? And what is it suitable for growing? Brown earth, also called brown forest soil, forms under warm-temperate deciduous broad-leaved forests and mixed coniferous-broad-leaved forests.

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 is dark loessial soil mainly distributed, and what crops is it suitable for growing
Dark loessial soil is a type of chernozem-like soil developed on loess parent material with a residual argillic horizon (commonly known as the dark loessial soil layer). The upper part of the dark loessial soil profile has a dark gray humus layer with cryptic argillic characteristics; although this layer is relatively thick and loose, its humus content is not
