The difference between organic fertilizer, inorganic fertilizer and biological fertilizer Two
The advantages are rich in organic matter and a variety of nutrients required by plants. Organic fertilizer is also an excellent fertilizer for soil improvement and soil fertility, which has a good effect on improving soil structure, increasing soil nutrient capacity, enhancing soil fertility and water conservation capacity, adjusting soil ph, promoting soil microbial activity and improving soil nutrient availability. The disadvantage is that nutrient concentration is low and fertilizer effect is slow, so the effect of increasing yield is not as significant as that of chemical fertilizer.
3.Biological bacterial fertilizer
The advantage is that it can activate the fixed nutrients in the soil, stimulate the growth and absorption of the root system, and reduce the amount of fertilizer applied to the corresponding nutrients.The downside is that it does not contain any nutrients and does not provide nutrients to the crop for long time .
After understanding their advantages and disadvantages, it can be concluded that the combined application of chemical fertilizer with organic fertilizer and biological bacteria fertilizer is better than the single application.However, in order to achieve the best effect of fertilization, the following problems should be paid attention to.
How to them match reasonably!
with the application of organic fertilizer in the orgainc agriculture, with uniform size granules and packages by the new type organic fertilizer granlulator and automatid packing machine, the crops yield is increased and high income is imporved, and the orgainc fertilizer also solve the problems of environmental pollution from livestock and poultry dung.
First, application time, effect of organic fertilizer is slow, should apply ahead of time, in general was used one-time base fertilizer before sowing, had better carry on decompose before use, chemical Fertilizer effect is fast, generally it is used for base fertilizer and applied a weekin advance, top application should be applied before the peak period of nutrients absorption to meet crops needs. Microbial fertilizer can only play the role of bacterial inhibition after massive reproduction in the soil, so it should be applied early in the premise of planting, so that it has time for breeding and expansion, it also can be applied into the soil along with organic fertilizer, and also can be applied before or during planting.
Second, pay attention to the application method. Main effect of organic fertilizer is improving soil, providing nutrients, generally was taken as basal application into the soil, the application of chemical fertilizer is the full soluble quick effect fertilizer, such as phosphate and potassium, they can be quickly absorbed by vegetables after decomposition, with little effect on soil. The application of biobacterial fertilizer can be concentrated in the planting hole or along with the base of organic fertilizer.
Thirdly , pay attention to dosage. Different crops require different amounts of fertilizer at different growth periods, Fertilization should be carried out according to the different fertilizer proportion of the crop need, and at the same time, the content of nutrient elements in the soil should be considered comprehensively.
