Organic Fertilizer and Chemical Fertilizer

When buying fertilizer or fertilizer machine, many friends may be confused withorganic fertilizer and chemical fertilizer. Which fertilizer to choose? So letslearn something about them.

The Benefit of Organic Fertilizer Comparing With Chemical Fertilizer

1. Organic fertilizer contains rich organic and various nutrient elements. Thedecomposed organic fertilizer provides energy and nutriment formicroorganism, promoting their activity and expediting organic decomposition.The active substance produced can promote the growth of the plants andincrease the products quality. Chemical fertilizer is now still the importantagricultural production in many countries. However, the single nutrient in it isnot good for the overall effect of soil. It has also caused single food,impoverished nutrition element and unbalanced nutrient substance in food.

Organic fertilizer can improve the physicochemical property and bioactivity.Too much chemical fertilizer can decrease the quality of product.

2.Organic fertilizer can improve the quality of soil. It can strengthen the abilityof water retention and fertilizer retention. Frequent use of chemical fertilizermay cause soil hardening.

3.The investment of organic fertilizer is far lower than that of chemical fertilizer.And the price is lower.

Then can we mix organic fertilizer and chemical fertilizer? The answer isyes. The chemical fertilizers that can be blended with organic fertilizer arecalcium superphosphate, powdered phosphate rock, urea and so on. Lets seethe advantages.

1. Organic fertilizer can absorb chemical fertilizer and promote its utilizationratio. Using chemical fertilizer alone may cause the nutrient fixed and runningoff. By mixing chemical fertilizer and organic fertilizer, the organic fertilizer willbe sooner decomposed, highly improving the fertilizer efficiency.

2. Adding the plants nitrogen nutrition. For example, by blending organicfertilizer with calcium superphosphate or calcium magnesium phosphate, wecan promote the growth of nitrogen-fixing bacteria in soil and rhizobium ofleguminous crop.

3. Since organic fertilizer has much nutrient, the nutrition of soil will be largelyincreased.

4. Applying chemical fertilizer singly or excessively will cause high watersolubility of soil, which is not good for plants absorbing water, and even causeseedling burning. By mixing chemical fertilizer and organic fertilizer, thisphenomenon will not arise. Besides, long time using acidic chemical fertilizerwill make the soil acidic, which is harmful to plants. Adding organic fertilizercan neutralize soil acidification.

5. Purify the living environment of people and plants. Make applying chemicalfertilizer safe, economical and effective.

Although there are so many advantages, some points should be noted toavoid mistakes.

1. Decomposed organic fertilizer cant be mixed with alkali chemical fertilizer,as ammonium nitrogen fertilizer is easily volatilized.

2. When decomposed organic fertilize is mixed with neutral or acidic chemicalfertilizer, it should be used immediately.

3. Nitrate nitrogenous chemical fertilizer is not suitable to mix withundecomposed organic fertilizer, for denitrification may cause nitrogen

volatilization.

4. Fresh grass and straw are not suitable to mix with nitrorgenous fertilizer,otherwise nitrogen would be absorbed and fixed by microorganism, then it willbecome slow fertilizer.
