What is the use of black soil, and what place does black soil refer to

1. Black soil.

Characteristics: 1) Precious black soil exclusive crops can be planted on the black soil to obtain high experience and high gold returns.

2) Ordinary land or red soil is planted on black soil.

crops, which can increase the yield bonus of crops by 20%.

3) Planting ordinary land or red soil crops on black soil can shorten the maturity time of crops by 20%.

4) The user must upgrade the black soil on the basis of the red soil.

5) There is a farm level limit for upgrading black soil, the higher the farm level, the more black soil plots can be upgraded.

20% reduction in growth time. Production increased by 20%.

Black soil refers to the black soil belt distributed in the Songliao River Basin of Heilongjiang and Jilin provinces in the shape of a crescent, which is the most fertile land in China. With a total area of 10 million hectares, more than 7 million hectares of cultivated land have been reclaimed, and its grain output has accounted for more than 60 percent of the two provinces, making it China's largest commercial grain production base.

Because the thickness of the black soil layer is 30 to 100 centimeters, people always use "one or two soils and two oils" to describe its fertility and preciousness. Black soil is a unique treasure given by nature to human beings, and it is a kind of soil with good characteristics and high fertility, which is very suitable for plant growth. There are only four major black soil areas in the world: the Ukrainian plain in Ukraine, the Mississippi plain in the United States, the northeast plain in China, and the Pampas steppe from Argentina to Uruguay in South America.

For those who have learned about the planting industry, they may have heard of the black soil, but they may not be too clear about what the black soil refers to.

The location of the black earthBlack soil in China generally refers to the black soil belt located in the Songliao River Basin of Heilongjiang and Jilin Provinces is the most fertile land in China, and the reason why it is black soil is because the land in this place is very fertile, so it is black.

Introduction to Black EarthBlack soil generally refers to a kind of soil with good traits and high fertility, which is very suitable for plant growth. At present, there are four major black soil regions in the world, namely the Ukrainian Plain of Ukraine, the Mississippi Plain of the United States, the Northeast Plain of China, and the Pampas Grassland from Argentina to Uruguay in South America, of which the Great Plain of Ukraine covers an area of about 1.9 million square kilometers; The black soil of the Mississippi River Basin in North America covers an area of about 1.2 million square kilometers; The area of the Northeast Black Soil Area of the Northeast Plain is about 1.03 million square kilometers; The area of black soil from Argentina in South America to the Pampa savannah in Uruguay is about 760,000 square kilometers. And except for the black soil of the Pampa savannah in South America, which is connected to Argentina in South America and Uruguay, the other three black soils are cold black soils.

For those who have learned about the planting industry, they may have heard that the black soil was talked about, but it may not be too clear what the black soil refers to, so let's take a look at it together.

Black soil in China generally refers to the black soil belt located in the Songliao River Basin of Heilongjiang and Jilin Provinces is the most fertile land in China, and the reason why it is black soil is because the land in this place is very fertile, so it is black.

Introduction to Black Earth

Black soil generally refers to a kind of soil with good traits and high fertility, which is very suitable for plant growth. At present, there are four major black soil areas in the world, namely the Ukrainian Plain in Ukraine, the Mississippi Plain in the United States, the Northeast Plain in China, and the Pampas Grassland from Argentina to Uruguay in South America, of which the Great Plain of Ukraine covers an area of about 1.9 million square kilometers; The black soil of the Mississippi River Basin in North America covers an area of about 1.2 million square kilometers; The area of the Northeast Black Soil Area of the Northeast Plain is about 1.03 million square kilometers; The area of black soil from Argentina in South America to the Pampa savannah in Uruguay is about 760,000 square kilometers. And except for the black soil of the Pampa steppe in the Americas and Argentina in the south to Uruguay, the other three black soils are cold black soils.

Black soils around the world are mainly used for growing cotton, wheat, corn, sorghum, rice, sugar cane or as pasture, with the largest area used for grazing. The natural fertility of black soil is very high, but the tillage is poor, and the availability of high water carrying points is low. Agronomic use varies depending on the climate, but their high clay content and low permeability during wet conditions make these soils suitable for waterlogged crops rather than timber forests.

The non-agricultural use of black soil often has many engineering problems. Roads, houses, pipelines, etc., will be displaced and distorted by the influence of soil expansion and contraction, so great attention should be paid to them. These soils have poor sewage absorption performance, and it is meaningful to measure their permeability value after soil moisture saturation and clay expansion, because if the permeability value is measured when the soil cracks in the dry season, it will be misunderstood that the soil permeability is particularly large, which is a problem that should be considered in the management of environmental culture delay.
