At the early times it is made by local materials in the countryside, it comes from a wide variety of material sources, general including human and animal dung, heap compost manure, cake manure, soil compost, mud manure, humic acid fertilizer, crop straw returned to the field and a variety of organic waste. These are the traditional ways to make organic fertilizer. Recently the emerging eco-agriculture, organic agriculture in the United States, Western Europe, Japan, and so on ,they focused on the use of organic fertilizer, and take organic fertilizer as the main source of green food production. And the organic fertilizer devices are used widely and play an important role in the markets. we self-develop multi-functional organic fertilizer equipment, which has the advantages of compact structure small footprint, and reliable operation. 

The effect of organic fertilizer:

1 Organic fertilizer can increase soil organic matter, which is the main material basis of soil fertility, and can improve soil structure, nutrient, energy, water and air permeability. Having great effects on microbial activity .

2. It contains a large number of nutrients and micronutrients required by plants, and the nutrient supply is comprehensive and stable and lasting, providing necessary conditions for the production of high-yielding, high-quality and pollution-free green food

3.  Improve soil enzyme activity, improve soil water conservation, fertilizer conservation and air permeability, and create a good environment for plant growth.

4. Organic fertilizers decompose in soil, produce various humic acids, and promote the enzyme activity, material synthesis, transportation and accumulation in plants. Adsorbing heavy metal ions is beneficial to the production of safe and healthy green food.

 

At present the following ways are the main methods to make the organic fertilizer according to different raw materials.

1. Animal waste, animal manure, such as chicken, pig, cattle, sheep, horse, rabbit, animal residue, such as fish meal, bone meal, feather, fur, silkworm excrement, biogas residue, etc.

2.Agricultural wastes. Crop straw, vine, soybean mean, rapeseed meal, cottonseed meal, caster bean meal, tea seed meal, yeast powder, mushroom residue, etc.

3.Industrial waste. Vinasse, vinegar residue, manioc waste, filter mud, herb residue, furfural residue, etc.

4.Municipal sludge. River sludge, pound sludge, ditch sludge, sea mud, lake mud, sewage sludge, humic acid, turf, lignite, danty, organic fertilizer production line, fertilizer granules fly, ash, etc.

5. Household garbage. Kitchen waste, etc.

6.Extracted or concentrated organics, seaweed extract, fish extract, etc.
