What is the material of the fertilizer bag

There are two kinds of plastic woven bags: PP and PE

PP (polypropylene), whose chemical name is polypropylene, is non-toxic.

PE (polyethlene), polyethylene, is also non-toxic.

There are many kinds of fertilizers, and the letters on the fertilizer bag are also diverse. Many farmers don't know much about the letters on the fertilizer bag, and they don't know what those letters mean. Here's an explanation.

Today, let's learn what some common letters on fertilizer bags mean.

Letter summary of common fertilizer packaging bags

1. HNK

In the process of using chemical fertilizer, we sometimes see some chemical fertilizer bags marked with HNK on the market. After consulting relevant information, there is no fertilizer with this mark.

Generally, the compound fertilizer we encounter is marked with NPK, and N represents nitrogen; P stands for phosphorus, with

P2O5 indicates; K refers to potassium and K2O.

2. TE

Te indicates that the fertilizer contains trace elements.

Manufacturers usually explain the content and form of trace elements in fertilizers in their technical manuals. The added trace elements mainly include boron, iron, zinc, copper and molybdenum, among which the chelated trace elements are the best.

For example, balanced water-soluble fertilizer: 20-20-20 + te. It means that the total nitrogen content of this water-soluble fertilizer is 20%, the content of phosphorus pentoxide is 20%, and the content of potassium oxide is 20%. Te means that the fertilizer contains trace elements.

3. EM

EM is a complex flora. We often see that the fertilizer bag is marked with EM agent, which is mainly composed of several major flora. All kinds of microorganisms play an important role, and the core role is dominated by photosynthetic bacteria and Lactobacillus acidophilus.

Its composition includes:

(1) Photosynthetic flora

It can use the solar heat energy received by the soil or use ultraviolet light as energy to separate hydrogen sulfide in the soil and hydrogen in hydrocarbons, and turn harmful substances into harmless substances. It is the main force to enrich the soil and promote the growth of animals and plants.

(2) Lactic acid bacteria

Lactic acid bacteria (anaerobic type) produce lactic acid based on the intake of sugars and other substances produced by photosynthetic bacteria and yeast.

It can transform immature organic matter into effective nutrients for animals and plants, and effectively inhibit the proliferation of pathogenic bacteria caused by continuous cropping obstacles.

(3) Yeast flora

Yeast (aerobic type) uses amino acids, sugars and other organic substances to produce activated substances that promote cell division through fermentation.

(4) Gram positive actinomycetes (aerobic)

It obtains amino acids and nitrogen from photosynthetic bacteria as substrates, and produces various antibiotics, vitamins and enzymes, which can directly inhibit pathogenic bacteria. It can enhance the resistance and immunity of animals and plants to various diseases.

(5) Filamentous flora of fermentation system (anaerobic)

Aspergillus, which is mainly used in alcohol fermentation, can coexist with other microorganisms, especially for the formation of esters in soil.

4. HFK

According to relevant information, no relevant letter meanings were found. It may be the exclusive fertilizer of some manufacturers, or it may be some fertilizer used by some small manufacturers to play the edge ball.

If you encounter such a letter on the fertilizer packaging bag, you must be careful, and you must go to a regular agricultural means store to buy fertilizer.

5. HAK

The Chinese name of Hak is potassium humate. Sometimes, compound fertilizers containing Hak appear on the market. Generally, compound fertilizers containing potassium humate.

The humic acid functional group in potassium humate can absorb and store potassium ions, prevent them from losing with water in sandy soil and elusive soil, and prevent the fixation of potassium by cohesive soil.

In addition, some parts of potassium humate are low molecular humic acids such as fulvic acid, which can dissolve minerals such as potassium silicate and potassium feldspar, and can slowly decompose to increase the release of potassium and increase the content of available potassium.

6. HA

Ha is humic acid.

Most humic acids in our market contain yellow humic acid, black humic acid and brown humic acid. Among them, the yellow humic acid in it has a regulating effect, which belongs to a growth regulator like agent, which can promote the growth of crops and control the expansion of crop stomata.

At the same time, a certain amount of yellow humic acid and potassium oxide can be extracted from humic acid to make potassium yellow humic acid.

Current scientific research shows that soil fertility largely depends on the content of humic acid in the soil.

7. FA

FA is fulvic acid, which is a plant growth regulator. It can promote plant growth, especially properly control the opening of stomata on crop leaves, reduce transpiration, play an important role in drought resistance, improve plant stress resistance, increase production and improve quality. It can be mixed with some non alkaline pesticides, and often has synergistic effects.

Some fertilizer manufacturers will say that it contains FA factor functional fertilizer.

8. TM and R

TM is a trademark that is being accepted. As long as it is accepted, it will generally succeed, and others cannot use it. R is a trademark that has been accepted successfully, and others cannot use it.

Particular attention

When buying fertilizers on the market, the labels of compound fertilizers are generally n, P2O5 and K2O, so you need to be careful if you encounter some fertilizers that are not labeled like this.

For example, there is a package marked as compound fertilizer, but the following total nutrients are marked like this: n-p2o5-kom or n-p2o5-hak, and the last one may be something else, but it is not K2O.

In the market, there are some compound fertilizers marked with the word "Kom" on the outer package, including manufacturers or dealers who explain that it contains potassium fertilizer. In fact, professionals say that "Kom" has nothing to do with potassium fertilizer, "Kom" is just a soil conditioning substance, which has the effect of dissolving phosphorus and potassium.

When you encounter such compound fertilizer, you have to pay attention. Be careful not to be fooled!
