90% of imported water soluble fertilizer may be fake! Farmers buy fertilizers to pay attention to screening

In recent years, various kinds of "concept" marketing, "misleading" marketing, "lie" marketing, and "out of nothing" marketing have emerged in the new fertilizers, with the aim of deceiving farmers. Some common tricks and "misleading behaviors" of counterfeit and shoddy fertilizers are introduced as follows:

Foliar spray can be used without base fertilizer and top dressing

At present, it is impossible to meet all the nutrient requirements of plants by foliar topdressing alone. Foliar fertilizer can only be applied as a very minor topdressing method (accounting for less than 5% of fertilization in the whole growth period)! Nitrogen fertilizer, calcium fertilizer, iron fertilizer, etc.

Water-soluble fertilizer

Foreign imports are currently the most common propaganda slogan. In fact, more than 90% of the so-called imported water-soluble fertilizers are domestically produced. It is their true purpose to sell high prices under the banner of imports.

In addition, some concept compound fertilizers that have appeared in recent years are also the trick.

Hormone fertilizers are rampant. Some farmers used fertilizer for 12 hours, and as a result, greenhouse tomatoes were planted at the end of April, and fertilizers without hormones began to pull out in June. Note that most hormone fertilizers have a pungent odor.

A variety of "potassium fertilizer" smashed the world. Potassium is more expensive, so some fertilizers directly name it as “××potassium”. This kind of fertilizer is often labeled with “potassium fulvic acid” and “high potassium”. In fact, many of its certificates are trace elements. No. The potassium content is very low.

One way of fertilizing, without the use of topdressing, is to seize the psychology of saving labor, saving labor and saving money. Some scammers often use fake and shoddy high-nitrogen fertilizers to pretend to be high-potassium fertilizers. The focus of the propaganda is on “only need to use the base fertilizer, and not to apply fertilizer later”.

After application, the yield and tree potential are significantly reduced, which brings direct economic losses. For the fruit tree area, its damage will last for 2 to 3 years.

Note: The demand for nutrients in different growth stages of crops is different. It is difficult to find a kind of fertilizer that can meet the crops of different growth stages. Compared with the demand for nitrogen and phosphorus in the spring, the demand for potassium in the fruit growing period is large, so different periods It is more appropriate to use the corresponding proportion of fertilizer.

In addition, the role of chemical fertilizers in the soil is relatively quick-acting. At present, it is difficult to achieve the effect of slow release for more than half a year. For the cultivation mode in the north, “small times” is applicable to various soils.
