Green fertilizer is a commonly used fertilizer that provides essential nutrients for plant growth. It is a nitrogen-rich fertilizer containing both ammonium and sulfur, making it a valuable source of these vital elements for plants. The use of green fertilizer offers several benefits in agriculture:

1. Rapid release of nitrogen as a source for fast plant growth.
2. Acidification of the soil, enhancing the absorption of nutrients by plants.
3. Supply of essential sulfur for protein formation in plants.
4. Versatile application for various crops and gardening.
5. Easily soluble in water for efficient nutrient uptake.
6. Low risk of nutrient leaching, resulting in minimal environmental impact.
