Most farmer friends can understand how extensive compound fertilizers are currently used in agricultural production. Compound fertilizers contain many elements, and many people use them. But when buying compound fertilizer, many people will make the following mistakes, let's take a look.
Misunderstanding 1: Imported compound fertilizer is better than domestic compound fertilizer
In fact, we can't say which one is better. Imported compound fertilizers do have good fertilizers, but relatively speaking, the price is not cheap. Considering the cost performance, there are still many good compound fertilizer brands in China.
Misunderstanding 2: Granular fertilizer is compound fertilizer
In fact, in addition to compound fertilizers, there are also single-element fertilizers such as large particles of urea, large particles of ammonium bicarbonate, nitrogen-containing formula fertilizers, and large particles of ammonium sulfate. When purchasing, you must look at the active ingredients marked on the package to determine.
Misunderstanding 3: Good fertilizers that will dissolve quickly
Generally speaking, nitrogen fertilizer is the easiest to dissolve, while phosphorus and potassium fertilizer dissolve more slowly. Generally speaking, the ones that dissolve quickly are absorbed quickly, and are also easier to lose, and the fertilizer effect is short. Therefore, the type of fertilizer to be purchased should be determined according to the need for fertilization.
Misunderstanding 4: High-concentration compound fertilizer is better than low-concentration compound fertilizer
In fact, the advantages of high-concentration compound fertilizers are high nitrogen, phosphorus, and potassium content and low consumption. However, in high-concentration compound fertilizers, the contents of nitrogen, phosphorus, and potassium are high, and the corresponding proportions of middle elements such as calcium, magnesium, and sulfur are reduced. If high-concentration compound fertilizers are used for a long time, calcium, magnesium, and sulfur will appear. Lack of symptoms.
Misunderstanding 5: White granular compound fertilizer is a good fertilizer
In fact, the color of compound fertilizer (compound fertilizer) is not necessarily related to the quality of compound fertilizer. What you really need to be careful of is those over-white compound fertilizers, perhaps just single-element fertilizers.
In summary, in agricultural production, fertilizers are very critical, and have a certain effect on the increase and yield of crops. Therefore, everyone must try to avoid misunderstandings when choosing fertilizers.
