Resource problem soil

Soil problems.
In Soil Soil (Soil) is a natural physique that a result of decomposition of various rocks and minerals. Mix, mix with organic matter. Earth's surface is covered in a thin layer. The object of sustained growth and balance of plant
Problems associated with resource soil
Problem soils found in each region are as many (Night town, 2538).
1. Lack of fertile soil.
Cause of lack of soil fertility and crop plants such as redundant Cultivation and land preparation is not a method The soil erosion Or soil erosion (Soil Erosion).
2. Soil conditions, pH or salt
Acid soil conditions or soil pH (Acid Soil) refers to the chemical reactions in soil acidity over the other or alkaline pH.
(PH) soil pH below 7 or alkaline soil conditions (Alkaline Soils) means that the chemical reactions in soil pH. With a pH over 7.
3. Soil organic peat soil or soil organic matter (Organic Soils) refers to land degradation caused by rotting vegetation decay of the wood. Nature depends on the watershed basin bath coop Killed deposition of thousands of years as long as thick litter layer caused by the deposition of this Dark red to brown. Or dark brown to black Organic matter is an element of more than 20% below the clay soil conditions are acidic areas.
The word for "swamp" is defined as the lowland flooding in the whole year based on the vegetation and deposition of dead. For several thousand years. The layers of soil organic matter Uu pure thick layer of uncertainty. But the heart of the thick peat most
4. Organized sandy (Sandy Soils).
Means that the soil is sandy clay or sandy loam of years. The layer thickness is greater than 50 cm soil contains.
Other sand sizes are quite rough. Is the porosity. Water seepage into the soil below easily. Can not absorb water
Or collect moisture in the soil. Leach plant nutrients to be easy. This gives a low fertility. Crops will not work.
5. Shallow soil.
Shallow soil (Shallow Soils) means the gravel laterite soils. Pebble or rock fragments in a number of shallow soil over 50 cm Or layers of rock. The barrier to root thread of the volume. The soil less And lack of reservoir of moisture and nutrients for plants. To deter abuse. Planting different crops.

6. Pollutants in the soil means the status of land received in the amount of contaminants.
Greater rate of decomposition or degradation effects of substances that cause.
The accumulation of various toxins or pathogens. Which causes harm to. Growth and reproduction of organisms in this ecosystem.
