The advantage of organic fertilizer is that it is a complete fertilizer with many kinds of nutrients, a variety of massive and micronutrient elements, and contains active substances such as vitamins. The most prominent feature is that it can increase and supplement soil organic matter.
Organic matter can improve the physical and chemical properties of soil, improve soil tillability, water seepage ability, improve soil water storage, fertilizer, fertilizer supply, drought and waterlogging resistance, increase yield obviously, which can not be achieved by chemical fertilizer.
Although, organic fertilizer has so many advantages, but a single use is not feasible, because after all, a large number of elements in organic fertilizer nitrogen, phosphorus and potassium are still very short, can not meet the needs of crops for nutrients, so organic fertilizer with chemical fertilizer is an ideal way to fertilize.
Quick effects of chemical fertilizers (as long as they are used properly) are important for sustaining stable and increased agricultural yields. We should follow the principle of fertilizing “mainly with organic fertilizer, supplemented by chemical fertilizer”, so as to achieve fertilizer soil yield increase. Research shows that the benefits of organic fertilizer with inorganic fertilizer are mainly reflected in 5 aspects.
Benefit one
The nutrient content of chemical fertilizer is high, the fertilizer efficiency is fast, but the duration is short, the nutrient is single, organic fertilizer is on the contrary, the mixture of organic fertilizer and chemical fertilizer can learn from each other, to meet the needs of crop nutrients in each growing period.
Benefit two
After fertilizer is applied to soil, some nutrients are absorbed or fixed in the soil, reducing the availability of nutrients. When combined with agricultural fertilizer, the contact surface between chemical fertilizer and soil can be reduced, the probability of chemical fertilizer being fixed by soil can be reduced, and the availability of nutrient can be improved.
Benefit three
Generally, chemical fertilizers have high solubility, resulting in high osmotic pressure on the soil after application, which affects the absorption of nutrients and water by crops and increases the chance of nutrient loss. If it is mixed with organic fertilizer, it can overcome this drawback and promote the absorption of nutrients and water by crops.
Benefit four
If acidic fertilizer is applied to alkaline soil only, ammonium is absorbed by plants, and the remaining acid roots combine with hydrogen ions in the soil to form acid, which will lead to increased acidity and intensified soil compaction. If it is mixed with organic fertilizer, it can improve the buffer capacity of soil, effectively adjust the ph, so that the acidity of soil does not increase.
Benefit five
Because organic fertilizer is microbial life energy, chemical fertilizer is to supply microbial growth and development of inorganic nutrition. The combination of the two can promote the vitality of microorganisms and promote the decomposition of organic fertilizer. Soil microbial activities can also produce vitamins, biotin, nicotinic acid, increase soil nutrients, improve soil vitality, promote the growth of crops.
