Humic Acid Good Effect

Jul 12, 2017

Humic acid fertilizers are suitable for all kinds of soil, Humic Acid but under different soil conditions, the yield effect is different.

Production test proved:

① the lack of organic matter in the barren and low yield field, Humic Acid the application of humic acid fertilizer yield increase; Humic Acid fertile soil in high yield fertilizers on the application of humic acid fertilizer can also increase production, but the magnitude of relatively poor barren soil

② poor structure of sand, Humic Acid saline soil, acid red soil soil humic acid fertilizer, yield effect is particularly evident.

③ Soil nutrient content had a great effect on the yield of humic acid fertilizer. Humic Acid The results showed that the yield of ammonium humic acid was higher than that of humic acid, Humic Acid and the effect of humic acid on the soil was low. Less, nitrogen and phosphorus serious imbalance in the soil, Humic Acid or on the fast-acting fixed soil more strongly, the fertilizer effect is more significant.

④ humid acid, humic acid fertilizer can absorb water, Humic Acid improve the breathable condition, the emergence of crops, hair root favorable; dry and dry land, humic acid, humic acid fertilizer can absorb water, Humic Acid water, Maintain soil moisture, reduce evaporation, and enhance crop drought resistance. Humic Acid It should be noted that humic acid fertilizer is hi water fertilizer, dry soil with irrigation, Humic Acid the effect will be better.

First, the humic acid fertilizer is selected according to the application method. If used as Chong Shi, drip irrigation or foliar spraying, it is recommended to use potassium humate, Humic Acid ammonium humate or potassium fulvate, ammonium fenvalerate. If used as a base fertilizer application, Humic Acid it is recommended to choose ammonium humic acid or ammonium nitrate humate and other fertilizers, the application should pay attention to buried in the soil, because humic acid ammonium humic acid and ammonium bicarbonate is the product of the combination, Humic Acid easy to volatilize, Shi or leaf spray. In addition, do not apply sodium humate in soils with high pH (saline).

Second, Humic Acid according to crop preferences and growth nodes choose humic acid fertilizer. To fruit trees, for example, the emphasis on fertilization in the fall of fertilizers, potash fertilizer, Humic Acid spring fertilization focus on nitrogen fertilizer, Humic Acid germination and differentiation of the focus on phosphate fertilizer and potash fertilizer, to the fruit enlargement period will need to focus on nitrogen fertilizer, potash, Humic Acid calcium and micro-fertilizer. In addition, but also with the preferences of crops fertilization. For example, fruit trees, Humic Acid eggplant vegetables, tobacco, sugar cane, etc. Humic Acid are hi potassium crops, Humic Acid the best application of potassium humate fertilizer.

Finally, humic acid fertilizers are selected based on crop category and cost. Humic acid fertilizer according to the type and quantity of nutrients divided into humic acid element fertilizer, humic acid compound (mixed) fertilizer, humic acid organic fertilizer, Humic Acid humic acid organic - inorganic compound fertilizer, humic acid trace elements fertilizer.

For the vegetable and fruit trees, Humic Acid you can choose humic acid organic fertilizer, humic acid organic - inorganic compound fertilizer or humic acid trace element fertilizer, these fertilizers, Humic Acid the use of humic acid, In the organic matter can reach 20% to 45%, Humic Acid can effectively improve the crop taste and color. If used as a spray or foliage spray, Humic Acid it is recommended to choose humic acid or fulvic acid-containing water-soluble fertilizer, although the price of the fertilizer is higher, Humic Acid but quick, effective, Humic Acid and therefore used for higher value of economic crops. Although humic acid can be used in the whole growth period of crops, but for economic reasons, after the crop transplanting, before the flower, swell, turn the four key period of the impulse 1 ~ 2 times, the expansion period and the color Combined with the spray effect will be better
