Anaerobic digestion is a remarkable and versatile biological process that can convert a diverse array of feedstocks into valuable resources. This includes plant biomass, animal manure, agricultural residues, municipal waste and any other biodegradable wastes. The end product of this process is known as digestate, which is the residue left after the anaerobic digestion of biodegradable material.
The transformation that occurs post-digestion is particularly noteworthy. Raw digestate, when enhanced with the right treatments and enrichment processes, can be converted into a nutrient-rich fermented organic fertilizer. This treated product holds the potential to significantly improve soil health and enhance crop production. The benefits of such organic fertilizers extend beyond nutrient supply; they contribute to the structure, moisture retention, and overall quality of the soil.

Feedstock
Standards (Issued by the regulatory commission / Government) typically regulate components like nutrient content, pathogen levels, heavy metals, contaminants, and other quality parameters to ensure the fertilizer's effectiveness and safety.
Nutrient levels that are too high, too low, or imbalanced.
For instance, excessive nitrogen can lead to nutrient leaching and groundwater contamination, while low nutrient content reduces the fertilizer's effectiveness.
Important physical parameters include, moisture content, particle size, texture, bulk density, water holding capacity, stability, maturity and odor.
Improper pH (alkalinity) and electrical conductivity (EC) can have several negative effects on soil health, plant growth, and the surrounding environment.
Results in soil nutrient imbalance and salinity, nutrient lockout, reduced crop yields, negative impact on microbial activity, root damage, seed germination and other environmental risks.
