In human waste, the addition of fine soil, turf, and other highly adsorbent materials can significantly enhance nutrient content and accelerate decomposition, leading to quicker fertilizer effectiveness. However, these substances are prone to nutrient loss, especially nitrogen. To mitigate this, incorporating soil or turf with strong adsorption properties into the septic tank—either by covering or mixing them with the waste—can effectively absorb urine and ammonia, thereby greatly reducing nitrogen loss. According to testing, adding 25% dry fine soil to human excrement can reduce nitrogen loss by approximately 10%.
Adding superphosphate to human waste is another effective method. Incorporating 3% to 5% superphosphate not only helps in minimizing nitrogen loss but also enriches the waste with essential nutrients like phosphorus.
Another option is the use of ferrous sulfate. Adding 250 to 300 grams of ferrous sulfate per 50 kilograms of human excrement helps protect nitrogen while also reducing odors, making it a practical and beneficial additive.
Gypsum powder can also be used. For each kilogram of human excrement, mix 5 kilograms of gypsum with 25 kilograms of water, stir thoroughly, and seal the mixture for 10 days. This process enhances the stability and usability of the waste.
When dealing with fresh cow dung, adding soy flour can improve its quality. Mix 50 grams of soy flour with 50 kilograms of fresh cow dung in a jar, seal it, and let it ferment for 3 to 5 days at 25°C. When applying this compost, it’s recommended to water it three times for better results.
Additionally, adding 2% superphosphate to the circular fertilizer (a type of compost) and allowing it to mature for about 20 days can more than double its fertilizer efficiency. This makes the final product more valuable for agricultural use.
By using these methods, farmers and waste management practitioners can significantly improve the quality and effectiveness of organic fertilizers while minimizing nutrient losses and environmental impact.
