Features

1. Wide applicability
   

   “Hei Dan "is a kind of natural macromolecule organic polymer with complex structure. It has many functional properties such as complexation, chelation, ion exchange, dispersion and bonding. It is used in combination with inorganic nitrogen, phosphorus and potassium to achieve nutrient balance , The proportion of scientific purposes, can be used for vegetables, fruit trees, flowers, nursery stock, tobacco, oil, tea, herbs, wheat, corn, rice and other food crops and cash crops, basal and top dressing.

2. Improve the soil

   Improve soil structure:In particular for longterm single use fertilizer caused by soil compaction significantly improve effect.For comparison barren and Sandy soil, "black Dan" can increase the soil cation Exchange capacity, the soil is fixed on plant useful metal cations like (k +, mg +) into a can be absorbed form, and then to promote plants to nutrient absorption.In agglomeration of soil, humic acid can with soil in the beneficial bacteria role and thus the soil become soft structure, but also promote plants to nutrient absorption.

   In and soil of acidity：Harmonic soil PH. In alkaline soils many of the basic elements and trace elements are present in an unabsorbed form, and humic acid acts as a buffer against pH, converting these essential nutrients and trace elements into a form that plants can absorb. In acid soils, it can react with heavy metals to reduce heavy metal pollution. At the same time, phosphorus fixed in the soil by Ca3 + Fe3 + Al3 + can also be released by plants. In the soil with higher salt content, it can be replaced by the salt-based exchange capacity Absorbed by crops.

3. Purify the soil：“Hei Dan "adsorption complexing ability, can reduce the poisoning of heavy metals and pesticides, improve the natural soil purification ability and water retention of fertility, so that farmland due to long-term use of chemical fertilizers caused by soil damage improved well.

Core Technology

The use of two activation techniques has successfully solved the problem of the traditional humic acid fertilizer molecular chain is too large, the absorption is too slow and the effect is weak. After the activation technology and other cutting-edge technology, activated phytic acid eliminates the organic matter humification time, make the fertilizer season play a role, let the soil replenish energy in time. Thoroughly solve the serious problems of traditional organic manure, slow manure conversion, slow success, and malposition of needed nutrients in crops.
