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.

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 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
