Ground was broken for several reasons might have occurred because of the nature or may be caused by an activity.Of human beings. Causing the occurrence of soil waste may contain: 1. originating from the origin (the Parent materials), mineral make up some rocks when the degradation.May cause changes to soil properties may cause the soil is much more toxic, such as: The soil is acid or acidic soil, soil salinity. The soil contains kammantaphap rays With heavy metals in the soil, etc.2. the biochemical reactions in soil sediments such as clay soil that has accumulated a lot of objects and organic is always present. Soil organic matter in the digestion process will cause a condition.Acids accumulate in the soil, making the soil is acid, for example, in the central group. Ground Fireworks, etc. 3. chemical fertilizer, chemical, fertilizer, or caused by any of the nutrients of plants are usually located on the ground always.Not so much in the forest, less like the allowable quantity of fertilizer is much less pla. For the use of the land for a long time. When the population increases. To increase output.Provide a sufficient intake of one way was to increase the fertilizer in the soil. Chemical fertilizers are.More popular because it results in quick response, but the use of chemical fertilizers have many restrictions. If used without caution, the damage to the soil in the long run because.The movement. Many of the In the use of chemical fertilizer, such as the processing of a element. (Transformation), ion exchange, adsorption (Ionexchange) (Absorption) sedimentation (Precipitation) to freeze elements. (Fixations) absorb foodsRoot crops (Absorbtion by plant root) nutrient loss in gas (Gaseous losses), etc. Therefore, if the use of chemical fertilizers have to be careful. If used correctly, will give you the output.In the long term, but if you use too much of each other for a long time may cause effects.Damage to the soil, such as phosphate phosphorus fertilizer to make the soil more residues. Urea fertilizer will.The soil is very acid. Ammonia fertilizer to soil are more acid. Fertilizers containing calcium.An element will cause the physical structure of the Earth, worsening. Fix difficult. Fertilizers that containCalcium and magnesium are the elements to make the physical properties of the soil.Better. N-P-K fertilizer if sufficient activity of miniature holders Li notri in soil, but if too much activity.Of the microorganisms is reduced.
