What are the Benefits of Mixing Chemical Fertilizers with Bio-Organic Fertilizers?
The application of mixed fertilizer is a clever way to improve agricultural products. The benefits of mixing fertilizers with bio-organic fertilizers are many. Let us understand the benefits of mixed application of chemical fertilizers and bio-organic fertilizers.
First, the combined application of chemical fertilizers and bio-organic fertilizers can improve the fertilizer efficiency of fertilizers. If calcium perphosphate or the like is applied to the soil and is easily fixed by the soil, it will be mixed with the bio-organic fertilizer and applied, which reduces the contact surface between the fertilizer and the soil, reduces the fixation of nutrients, and the fertilizer can also be absorbed and preserved by the bio-organic fertilizer. Reduce nutrient loss.
Secondly, it can also reduce some of the side effects that may occur after the application of chemical fertilizers. When the application of large quantitative fertilizer or uneven application of chemical fertilizer is easy, it will easily cause toxic and side effects on crops. For example, long-term application of physiological acid fertilizer will make the soil acidic, and produce excessive toxic substances such as active iron and active aluminum, such as excessive free acid. The superphosphate is used as a seed fertilizer to affect seed germination and seedling growth. If it is mixed with bio-organic fertilizer, it will not occur.
The combined application of chemical fertilizers and bio-organic fertilizers can also increase crop nutrients. Fertilizers can only provide one or several nutrients for crops, and long-term application can lead to deficiency. Bio-organic fertilizer contains comprehensive nutrients, stable and long-lasting fertilizer, and contains a large number of beneficial microorganisms and organic matter, which can improve soil physical and chemical properties and microflora, enhance enzyme activity in soil, and facilitate nutrient conversion.
In addition to supplying various nutrients to crops, organic fertilizer can also renew and accumulate soil organic matter, promote soil microbial activities, facilitate the formation of soil aggregate structure, coordinate soil fertility factors such as water, fertilizer, gas and heat, and enhance soil fertility. Fertilizing capacity. Fertilizer has the characteristics of high nutrient content and fast fertilizer efficiency, but the duration of fertilizer effect is short and nutrients are single. If the two are scientifically matched, it will not only prevent the loss of the active ingredients, but also greatly improve the fertilizer efficiency and meet the nutrient needs of the crops in each growth period. The benefits are quite a lot:
First, it can provide nutrients for crop growth more comprehensively. Organic fertilizer contains more nutrients, and the fertilizer effect is stable and long. It can not only supply crops, but also supply soil microbes such as nitrogen, phosphorus and potassium, as well as vitamins and growth hormones. After the application of organic fertilizer, the enzyme activity in the soil is enhanced, which is beneficial to nutrient conversion. For example, organic fertilizer mixed with superphosphate can promote the growth of autotrophic nitrogen-fixing bacteria in the soil and increase crop nitrogen nutrition.
Second, it can improve fertilizer efficiency. Fertilizers such as superphosphate and trace elements are easily fixed after being applied to the soil to reduce the effectiveness of nutrients. If the fertilizer is mixed with the organic fertilizer, the nutrient is reduced by reducing the contact surface between the fertilizer and the soil, thereby reducing the nutrient fixation. Another example is that after mixing a lot of chemical fertilizers with organic fertilizers, chemical fertilizers can be absorbed by organic fertilizers to reduce losses. Furthermore, the blending of chemical fertilizers and organic fertilizers can also promote the decomposition of organic fertilizers and improve fertilizer efficiency.
Third, it can reduce the side effects caused by the separate use of fertilizer. When the application of larger quantitative fertilizer or fertilizer application is not uniform, the concentration of soil solution is often high, which affects crop absorption. In addition, if the physiologically acidic fertilizer is applied alone for a long period of time, the soil becomes sour, resulting in soil compaction. If the fertilizer is mixed with organic fertilizer, this can be largely avoided.
Fourth, it can accelerate the decomposition of organic matter. Fertilizer can supply inorganic nutrients for microbial growth and development, and farmyard manure is an energy source for microbial life. For example, when straw is returned to the field and unfertilized organic fertilizer is applied, the addition of chemical nitrogen fertilizer can prevent crops from affecting growth due to early nitrogen deficiency.
