soil. The naturally occurring material is eroded from the decomposition of rocks and minerals. The decomposition of dead plants and animals. Mixed compound Influenced by the environment, such as climate conditions and timing of developing different. There are various types of soil Earth's surface is covered in a thin layer. As an anchor and plant growth. As well as a source of food, water and other creatures. Residents of the soil and the soil on
agricultural soils have
a soil problem in agriculture means. Soil physical and chemical abuse or less suitable for cultivation. Plants can not grow and produce normal. Most of the soil occurs naturally saline soils are sandy clay soil, organic soil, gravel and shallow soils also include areas with high slope. If you already have an advantage in agriculture. The impact on the ecosystem and the environment severely. If you use these soils for crops already. Have managed to fix the soil properly before planting the usual manner before
the degradation of the soil,
soil degradation is a change physicochemical properties and biological properties of the soil. The soil quality has fallen and can not be used for agricultural production and permanently fixed forever. The result of the lack of ground handling is required. And the economic and social
problems of soil
, soil largely destroyed in the loss of fertility. Or ground beef due to human actions. And the loss of natural causes, we can not take advantage of the ground's full potential. Soil loss caused by
one. Erosion and erosion by water. A lot of water on the surface directly to soil erosion. The water passes through the The loss of surface area to a wider area. Or eroded a little groove, it depends on the strength. And the area of water runoff into the
second. The deforestation and burning forest harvesters make open ground. And can be easily washed by water and wind, the rain. The water was washed out with water, fertile soil. Soil quality deterioration
3. Planting and tillage are incorrect. Land preparation, planting, if not, it will be a disservice to the ground, for example. While tilling the soil, making the soil dry completely slip away with the wind. Or planting some plants will deteriorate rapidly burning forest soil or stubble in the field. Humus soil degradation will result in damage to the soil.
