Why Does the Content of Compound Fertilizer Not Exceed 56?

Who said there is no more than 56% compound fertilizer? Is 64% diammonium phosphate compound fertilizer? Is potassium dihydrogen phosphate containing more than 86% compound fertilizer? Compound fertilizer does not only contain the three elements of nitrogen, phosphorus and potassium, it can also contain two elements of nitrogen and phosphorus, or phosphorus and potassium. As an NPK Compound Fertilizer Manufacturer, share with you.

What is compound fertilizer?

Compound fertilizer refers to a kind of chemical fertilizer that contains two or more of the main nutrients such as nitrogen, phosphorus and potassium at the same time, which is called compound fertilizer. The two main nutrient elements are called binary compound fertilizers, such as diammonium phosphate and potassium dihydrogen phosphate. Containing three main nutrients is called ternary compound fertilizer, such as our commonly used ternary compound fertilizer of nitrogen, phosphorus and potassium. And those with more than three nutrient elements are called multi-element compound fertilizers.

NPK Compound Fertilizer

The nutrient types and matching ratios of various compound fertilizers are different, and their nutrient content and effective ingredients are also different. Generally speaking, the total nutrient content of compound fertilizer is mostly in the range of 25%-60%. Those with a total nutrient content of 25%-30% are low-concentration compound fertilizers, those with 30%-40% are medium-concentration compound fertilizers, and those with more than 40% are high-concentration compound fertilizers.

High-concentration compound fertilizers are a trend in the development of compound fertilizers. People tend to prefer compound fertilizers with high nutrient content in fertilizer selection. For example, compound fertilizer products with NPK content of 15-15-15 and 17-17-17 are very popular. Favor. In fact, if a fertilizer only has a high nutrient concentration and an inappropriate nutrient ratio, its yield increase effect is not good, and the fertilizer utilization rate is low.

For example, compound fertilizers with a nitrogen, phosphorus and potassium content of 15-15-15 are effective when used on newly reclaimed slopes with heavy phosphorus deficiency. However, for many farmlands, the ratio has a big problem, mainly due to the excessive phosphorus ratio. High, it should be used very cautiously on the cultivated ground. For example, we grow a lot of ginger here, and the three 15 compound fertilizer ginger farmers do not like to use it. Most of them choose the ternary compound fertilizer with higher potassium content, because ginger has a large demand for potassium.

Fertilizers with high nutrient content can give full play to their effects only under the premise of high utilization rate. Otherwise, not only will the cost be high, but it will also easily cause eutrophication of water bodies and pollute the environment such as water bodies.

At the same time, high-nutrient compound fertilizers are also toxic, such as killing seeds and burning seedlings. Farmers have some preferences. They do not look at the concentration of compound fertilizer, but apply it at the level of 45 they are using, which is likely to cause fertilizer damage.
