Which new fertilizer is suitable for orchard application
New fertilizers include microbial fertilizers, controlled release fertilizers, and bio-organic fertilizers. Its role is to provide the necessary nutrients for crops, improve soil structure, and improve fertilizer efficiency. But there are so many new types of fertilizers on the market, which type is more suitable for orchards.
Microbial fertilizers are fertilizers that contain large amounts of beneficial microorganisms. They are mainly composed of beneficial microorganisms and the matrix required for microbial life activities. It includes anti-phosphorus and potassium-dissolving bacteria that can activate phosphorus and potassium nutrients, anti-bacteria that can improve the stress resistance of crops, and decomposing bacteria that can promote the conversion of organic substances.
Slow-release fertilizers combine or envelop substances that are insoluble or difficult to be degraded by microorganisms with fertilizer nutrients (mainly nitrogen), or make fertilizers into large particles, so that nutrients are slowly released after the fertilizer is applied to the soil. Therefore, the utilization rate of the fertilizer can be improved and the pollution to the environment can be reduced.
Humic acid or chelating agent can improve the availability of these nutrients in micro-fertilizers and soils by converting iron, manganese, copper, zinc, molybdenum and other elements that are easily fixed in the soil into substances that are easily absorbed by crops. . Because of this, some products refer to humic acids or chelating agents as "activators."
Farmers' friends should pay attention to the following two points when purchasing "new fertilizers": First, the efficacy, nutrient content and quality inspection standards of "new fertilizers" are not as clear as ordinary fertilizers, and fertilizer costs are relatively high. Therefore, more attention should be paid. Prevent counterfeit and shoddy products and use them with force. The second is to ask the experts or refer to the practice of others for the "new fertilizer" that they don't know yet. If you don't have a bottom in your heart, and you want to use it, you can try it on a small piece of land.
