organic fertilizer

Solid organic fertilizer can stimulate the activity of microorganisms so that the conditions of chemical, physical and biological soil better. in general, the benefits of solid organic fertilizer is as follows:

1. Adding Fertility Plants

Organic fertilizers, including compound fertilizer because it contains macro nutrients (N, P, K) and micro elements (Ca, Mg, Fe, Mn, Bo, S, Zn, and Co) which can improve the structure of soil fertility. Organic fertilizer can improve soil porosity. In the land of ugly clay-like structure with the addition of organic matter will reduce the stickiness so easy to be processed. while on sandy soil, adding organic fertilizer can increase the soil to hold water and nutrients.

2. Improving Soil Chemical Conditions

In acid soil, the ions that plants need in a condition likely to be bound. With the presence of organic fertilizer will be binding and ion release system in the soil so that it can support plant growth.

3. Improving Soil Biology condition

Organic fertilizers stimulate beneficial soil microorganisms like rhizobium, mycorrhizal, and bacterial decomposers or potassium phosphate. O2 and CO2 concentrations in soil associated with biological activity.

4. Improving Soil Physical Condition

water binding ability of organic fertilizer can make better soil porosity so that it can support respiration and growth of plant roots.

5. Safe use of Human

The use of organic fertilizers do not leave residue on the crop so that no negative effects to human health.

6. Not Pollute the Environment

Organic fertilizers do not pollute the environment. while chemical fertilizers are absorbed by plants about 30-60%, the rest being absorbed in the soil or washed away by water. agricultural land adjacent to settlements such as wetland water flow is also used for daily needs would jeopardize long-term health.
