Foliar fertilizer

☆ ① About foliar fertilizer

Question 1. Why Use the Foliar Fertilizer?

▲Plants absorb micro nutrients through their leaves faster than their roots

▲Offers micro nutrients that crops need

▲Easy to use/water soluble

▲Certain foliar fertilizers offer specific function i.e. growth hormones

▲Correct micro nutrients deficiency

Question 2. Can foliar fertilizers replace traditional chemical fertilizers (N.P.K.)?

▲No chemical fertilizers (N.P.K.) are the main-stream macro nutrients that crops need. There are no complete alternatives to N.P. and K.

▲However, micro nutrient deficiency in soil needs to be corrected. Micro nutrients deficiency can be caused by:

1.Natural depletion of micro nutrients content in soil;

2.Loss of micro nutrients during harvest time;

3.Natural characteristics of soil which contains insufficient micro nutrients (i.e. Sandy soil is in lack of Boron etc.)

4.Even though some soil is rich in micro nutrients, it might not be able to release these nutrients for absorption through root

▲Since the introduction of foliar fertilizer, it has become more and more desirable in agricultural treatment of crops in large-scale field cultures. Generally foliar fertilizer comes in the form of a well-balanced mix of micro nutrients to influence the intensity of photosynthesis. If a product’s chemical content is properly prescribed, uptake of the whole dose lasts from several hours to several days. It is also estimated that foliar feeding with micro nutrients is 10 times more effective that soil fertilization.

▲Foliar fertilizer has been a popular form of fertilizer in the United States and Europe today. However, the concept of foliar feeding is relatively new in China. The introduction of foliar fertilizer for commercial utilization was in the 80’s. Since its launch, it has been well accepted by China’s farming communities as it is easy to use and economical.

☆ ③ The mechanism of Penshibao

The mechanism of “Penshibao”

(Institute of New Technique of Penshibao)

Penshibao (PSB) is a stable and very good fertilizer with the most effectiveness and the greatest extended area.

What is the mechanism of the activity of PSB with a such low spraying concentration (only75ml/ha in 750 kg water,i.e.1:10000) on the leaves ? This is the question that many Chinese and foreign specialists follow with interest.

Here is he mechanism which the specialists in this institute found. PSB is a product that mixed by the extraction from the natural plants as active ingredients with the necessary microelements. The mechanism as follows:

1. PSB contains many amino acids:

By the chemical analysis, the product of PSB contains many amino acids. The content of amino acids are shown in Table 1.

There are 8127.4 ppm amino acids (total) in PSB. If dilute 10000 times with water, the concentration is still 0.81 ppm. According to the literature, in general amino acids are active when the concentration is 1 ppm, and some of the amino acids are active enough when the concentration is only 0.1-0.01 ppm. If the concentration is too high, the inhibition effect will be appeared.

Recently, it is reported that some of the amino acids show very high physiological activity. They stimulate the growth of plants. It si concerned to the endogenous plant hormones ,i.e. when the amino acids are provides, they stimulate and increase the endogenous plant hormones (e.g. auxin, cytokinins, etc.) or inhibit some endogenous hormones (e.g. abscisic acid, ethylene, etc.).

The another function if amino acids is that they can stimulate the absorption of the nutrient elements, e.g. Glycine can increase the absorption of P,P,K; DL-lycine can increase the absorption of P,N; Aspartic acid and L-Serine can increase the absorption of P,K; DL-Alanine can increase the absorption of P,etc.

Amino acids and their derivatives have the ability to control some plant diseases, e.g. Methioine can control the root rot of rice, threonine, Lycine and Serine can control the black spot of lemon;Glycine, Valine, Isoleucine and the cupric salt of Tryptophane can control the sheath and culm blight of rice, etc. Amio acids also have the ability to form the complex with microelements and promote the absorpton and transportation of microelements.

　2. PSB contains many Vitamins:

Vitamins, as well as amino acids, are the nutrition resources for the growth of plants and animals. The content of vitamins in PSB are very high, especially Vit.B. The analysis results are showed in Table 2.

Some vitamins may be synthesized by plants, but the amount is not enough. Vitamins are the composition of coenzymes. Some of them have the effect of antioxidation and can regulate the bimembrances. Vitamins can stimulate the absorption of N, P, K and check the symptoms caused by the lack of Mg and Zn. Vitamins may build up the resistance of plant to air pollution and drought and other calmilies.
PSB contains many vitamins , which may stimulate the growth and development of plants, e.g. Vit. B1,B2,B6 and Vpp may stimulate roots. Nowadays they are used in agriculture. Other vitamins can also regulate the growth and development of plants directly or indirectly. It was reported that vitamin can used in seed soaking in concentration of 10-100 ppm, and Nicotinic acid ﹤ ppm is enough. The amount of vitamins in PSB is quite enough.

3. PSB contains different kinds of saccharides.

There are many kinds of saccharides in PSB. (Table 3).

Saccharides effect plants directly. The hydrolyzed products of polysaccharides have the strongest bioactivity, i.e. induce antibiotics in the plants, improve the ability of resistance of drought and other calmilities; realize the rapid reaction on the surface of cell and membrance, increase the permeation of the membrance and promote ions into the plants; effect the formation of endogenous plant hormones, thus effect the metabolism of plants. Saccharides can also release the injury caused by excess fertilizers. It was reported that amount of Tetrasaccharides and pentasaccharides are the highest in PSB and they are most effective.

4. PSB contains Fulvic acid:

Fulvic acid is a compound with the lowest molecular weight in Humic acids, and has the strongest bioactivity and chemical activity.
Fulvic acid in PSB, can decrease wht opening size of the stoma, decrease the evaporation of water on leave surface, maintain the water metabolism in normal, thus raise the ability of drought resistance. Fulvic acid can also transport from leaves to roots, stimulate root development and improve the ability to absorb water and soil nutrition. Fulvic acid may form complex with microelements, improve the absorption of microelements and transportation in the plants. It is benefit for the release physiological diseases owing to the lack of microelements.

5. PSB contains many microelements:

There are many microelements mixed in PSB, especially B and Zn. The content of B is 0.3% and Zn 1.0%. Most of them form complex with amino acids, Fulvic acids and other organic acids. The active concentration of these complexes is lower than that of in-organic ions about 10-100 times, so that PSB was diluted with 10000 times water, the activity of microelements is still apparent. For instance, if B is lack in cotton or Zn in rice, the symptom will be diminished obviously after spraying PSB.

6. Conclusion

PSB contains various amino acids, vitamins, saccharides and Fulvic acids and the plant demand microelements with strong bioactivity and chemical activity. PSB will realize the effect of growth regulation, drought resistance, fertilizer effectiveness, thus raise the amount of the chlorophyll, the activity of enzymes, respiratory intensity, promote the absorption of soil nourishment,finally make plants develop strongly, raise the yield, improve the quality, and give the god results.

We will report other mechanism of PSB further.
