How does the slope of the land affect soil erosion?

Slope Land Sloping cropland generally refers to cropland with a slope greater than 6° Sloping cropland generally refers to cropland with a slope greater than 6°. This type of cropland is a usually dry land with poor ground leveling, prominent water and fertilizer runoff, and low crop yield. Soil erosion refers to the process of soil or its parent material being stripped, destroyed, separated, transported, and deposited under the action of external forces such as water, wind, freezing and thawing, and gravity. According to different types of external forces, soil erosion is mainly divided into hydraulic erosion, wind erosion, gravity erosion, and freeze-thaw erosion. “Soil erosion is mainly divided into hydraulic erosion, wind erosion, gravity erosion, and freeze-thaw erosion.” Soil erosion on sloping land in China is mainly prominent in the loess soil on the Loess Plateau, the red loam soil in the upper Yangtze River hills, the purple soil in the Chuanzhong hills, and the black soil in the Northeast Plain. Among them, Loess Plateau is the most serious and concentrated area of soil erosion on sloping farmland in China. Severe soil erosion has caused thousands of hills and ravines, bare hills and bald mountains, and frequent disasters on

What’s the fiber materia of silt sock fabric HDPE?

HDPE High-density polyethylene (HDPE) is an environmentally friendly material, which is resistant to acids and bases, organic solvents, excellent electrical insulation, low temperature, can still maintain a certain degree of toughness. Surface hardness, tensile strength, rigidity, and other mechanical strength are very high. High density polyethylene (HDPE) is a thermoplastic polyolefin produced by copolymerization of ethylene. HDPE is typically manufactured using the Ziegler-Natta polymerization process and is characterized by the absence of branched chains in the molecular chain, resulting in a regular molecular chain arrangement and a high density. The process uses ethylene as the raw material in a tubular or kettle-type low-pressure reactor and initiates the polymerization reaction with oxygen or organic peroxide as initiator. Low water absorption; poor aging resistance, which can be greatly improved by adding antioxidants and UV absorbers to the resin. “Aging resistance can be enhanced by adding antioxidants and UV stabilizers to the resin.” Basic Properties High-density polyethylene (HDPE) raw material is an opaque white waxy material, lighter than water, specific gravity of 0.941 ~ 0.960, soft and tough, elongation, non-toxic, tasteless. Melting point is 142℃, decomposition temperature is 300℃. Flammable, can continue to burn after leaving the fire, the upper end of the

What are 3 major harmful effects of soil erosion

What are 3 major harmful effects of soil erosion?

Main Hazards Of Soil Erosion When soil erosion increases, it leads to loss of ecological balance and frequent droughts and floods, and the situation will become more and more serious.  There are many causes of soil erosion, which were mentioned in the previous article ——“What is the main causes of soil erosion?”. So what are the hazards of soil erosion? There are three main hazards. 1. Serious soil erosion leads to the loss of soil fertility The amount of food consumed each year in each country is considerable, and this requires that people who produce have the technology to maintain the fertility of land resources to deal with the increasing erosion. Soil erosion leads to a lack of effective accumulation of organic matter in the soil, which reduces the fertility of the soil, and the fertility of unvegetated slopes is greatly reduced when they are washed away by heavy rains. In addition, soil erosion can have a series of negative effects on the physical and chemical properties of the soil and the agricultural ecology. “Soil erosion destroys the original structure of the soil, causing the surface layer to harden and microbial activity to become difficult, which can affect the growth

What is the main causes of soil erosion?

What is the main causes of soil erosion?

Soil Erosion If human beings carry out reasonable production activities, they can make it impossible for these natural factors to be in a bad state at the same time, thus slowing down the frequency of soil erosion. In recent years, with the development of the world economy, the problem of soil erosion has been paid more and more attention. So, what are the causes and hazards of soil erosion? How to solve soil erosion? Let’s take a look below! In many countries, the main cause of soil erosion is due to poor natural conditions and unreasonable daily activities of human beings. The main causes of erosion are uneven ground with a high slope; soft soil texture, which is easily eroded; heavy rainfall in the rainy season, which covers the ground with forest and other vegetation. Human unreasonable daily activities such as some people do not have a strong sense of environmental protection and regularly cut down trees to open up the land, the grassland is flooded with cattle and sheep, overgrazing, excessive mining, etc. Soil erosion is the result of the interaction between natural and human factors. “Natural factors include the topography, geomorphology, climate, and soil of the country.”The human
