What is the main difference between water soluble fertilizers?

Massive element water soluble fertilizer concept

Water Soluble Fertilizer is a multi-component fertilizer that can be completely dissolved in water. It can be quickly dissolved in water, more easily absorbed by crops, and its absorption and utilization rate is relatively high. In addition, it can be It is applied to facility agriculture such as drip irrigation to realize the integration of water and fertilizer, and achieve the efficiency of water saving and fertilizer saving.

Implementation standards:

A large amount of water soluble fertilizer NY1107-2010

Containing amino acids: NY1429-2010

Trace element water soluble fertilizer: NY1428-2010

Containing humic acid water soluble fertilizer: NY1106-2010

Everything has a standard. The national standard refers to the standard issued by the national standardization authority, which is of great significance to the national economic and technological development and is unified throughout the country. The following series of ten questions and ten answers will be organized around these standards.

First, when it comes to water-soluble fertilizer, everyone is saying that there are too many water-soluble fertilizers in the market? Indeed, since the integration of water and fertilizer has been proposed, this water-soluble fertilizer has been imitated, but still can not surpass the reality, not to mention our farmers, sometimes our sales staff (including dealers and manufacturers) are not clearly defined Water soluble fertilizer type! A lot of very general sentence, I am doing water soluble fertilizer! This is worth thinking about, because the different types, its price, its effect is completely different, can not be confused, this will only hinder their progress, of course, will also hinder the progress of China's agricultural resources! (Please distinguish the type)

Second, is it cheap and expensive? Not the same, the regular manufacturers are sufficient, the content is only high, and the national standards are strictly enforced.

Some manufacturers like to play the ball, less than two pounds, and the number is too much. This is hard to say. Conditional friends can send their own products to check and see if they will be scared!

Third, the cheap and expensive is the source of the raw materials is the same? Not the same, for example, taking the nitrogen source, it can be derived from monoammonium phosphate, diammonium phosphate, potassium nitrate, urea ....., the source of raw materials is not only divided into varieties, but also the purity grade, a source of nitrogen is industrial The grade of diammonium phosphate, the other is urea, Imagine how much this price difference!

Fourth, a lot of water soluble fertilizer prices are low, the performance after use is also good. Why? Now most manufacturers are raising the nitrogen content, reducing the potassium content, or even not. For example, after 20-20-20 is used for 30-15-5 content, Miao Qi Miao Zhuang can be de-fertilized later. The final output will not go up. (Just give a chestnut)

5. Why is the effect of cheap water-soluble fertilizer better than that of brand-name water-soluble fertilizer? Here we must pay close attention to two concepts: "effective period" and "fat period". Water-soluble fertilizer is a kind of multi-component compound fertilizer. It can't explain to everyone's image. Borrowing big fertilizer, carbon ammonium is effective on the same day, the fertilizer effect period is 15 days; ammonium chloride is effective for three days, fertilizer effect period is 25 days, and later fertilizer is removed. Urea, effective in seven days, fat effect period of 45 days. The compound fertilizer is effective for ten days, and the fertilizer effect period is 90 days. Here in real life, our farmers' friends only pay attention to the immediate effect, but do not care about a continuous situation, which makes the good water soluble fertilizer to a certain extent passive.

6. How should we calculate the investment cost, is it correct and feasible? Cheap 4 bags of 20 kg each time, 200 yuan / mu. The regular water-soluble fertilizer is 10 kg each time, 180 yuan/mu, a good fertilizer that really saves money. In addition, regarding the crop harvest, I don’t think I have to say more!

7. Why do you think that the output of the cheap water and water soluble fertilizer has been rising since then? Here, we can use the nutrient return theory to make a good explanation. The crops take nutrients from the soil, and the nutrients in the soil will be less and less. Therefore, to restore the soil, all the nutrients should be returned to the soil and all the things taken from the soil should be returned. Otherwise the output will drop. Good fertilizer, the more fertile the land, the higher the output will not increase, but it can be guaranteed that there is a steady rise, poor fertilizer, the output is destined to be short-lived, if not stopped in time, it will gradually drift away!

Eight, why do some water-soluble fertilizers have certificates, the inspection is qualified, and the price is still much cheaper? Now the functional department only tests N, P, and K. If there are a lot of small factories, you can do a good job on the surface. Regular manufacturers have added trace elements, and on the content table, the number of labels will definitely contain how much, trace elements. A few tens of thousands of yuan per ton, plus or not, plus more plus less, this price of course varies greatly!

9. What is the difference between cheap fertilizer and regular fertilizer outsourcing? Based on experience, you can see if there are product execution standards, product generic names, and fertilizer registration numbers. Careful and professional, you can also check whether the heavy metal content is marked on the bag. The heavy metal ion content of a large number of elemental water-soluble fertilizers produced by regular manufacturers is lower than the national standard and is clearly marked. If the fertilizer packaging bag is not marked with heavy metal content, please use it with caution!

10. Is there any difference between water-soluble fertilizer and rushing fertilizer?

1, first of all conceptually:

Simply put, a water-soluble fertilizer is a multi-element compound fertilizer that can be quickly dissolved in water (with or without precipitation). The standard for this classification is the physical properties of the fertilizer, that is, its ability to dissolve quickly in water.

In addition, water-soluble fertilizer is an academic concept or legal concept, and flushing is a common name. The so-called academic concept means that in the strict classification of fertilizers, it can exist as an independent category. The so-called legal concept refers to the Ministry of Agriculture's fertilizer registration management method, which is a fertile variety that can be declared. It can be said that the application of fertilization is a common saying, this is just a statement that there is a method of use in the practice of fertilizer consumption.

Rushing and fertilizing is also called water-flooding. It is a kind of topdressing method, which is a method of fertilizing solid quick-acting fertilizer in water and using water to fertilize. The fertilization is the fertilization, and the irrigation method can be divided into well irrigation and irrigation, including drip irrigation and sprinkler irrigation. The raw materials used for the fertilization are relatively common. The first raw material: the material used for the fertilization can be a completely water-soluble raw material. The second raw material and the raw material used for the fertilization may also be an incompletely water-soluble raw material.

2. How to use fertilizer

The material used for water-soluble fertilizer is relatively strict. First, the liquid after water dissolution has no sediment. Second, the raw materials used must be quickly soluble in water. Third, the heavy metals contained in the water-soluble fertilizer raw materials cannot exceed the standard. The fertilization can be either a water-soluble fertilizer or a water-soluble fertilizer. As long as the water can be diluted into a liquid and then applied with the water, it can be called fertilization, such as compound fertilizer, human excrement, not originally fertilized, after you dilute it with water to apply liquid, they become flush fertilizer.

There are two completely different concepts for flushing and water-soluble fertilizers. Some manufacturers and distributors deliberately confuse them, and then take the opportunity to fish in troubled waters. Finally, I suffered from the people, messed up the market, and harmed the regular manufacturers... (191 agricultural capital)
