Organic fertilizer is a natural soil amendment derived from plant, animal, or mineral sources. Unlike synthetic fertilizers, it not only provides essential nutrients (N-P-K) but also improves soil structure, enhances microbial activity, and increases water retention. Common types include compost, manure, bone meal, and seaweed extracts. By releasing nutrients slowly and improving soil health, organic fertilizer promotes sustainable agriculture, reduces environmental pollution, and produces healthier crops. It is ideal for organic farming, home gardens, and any agricultural system aiming for long-term soil fertility and ecological balance.

EDDHA, is a chelate that protects nutrients against precipitation in a wide pHrange: 4-10, which is higher than EDTA and DTPA in pH range. This makes the EDDHA-chelates suitable for alkaline and calcareous soils .EDDHMA-Fe and EDDHSA-Fe are also available.
