What are Worm Castings?
Vermicompost, also known as worm castings, is a nutrient-rich natural fertilizer produced by earthworms as they break down organic matter. Here are some of the key nutrients found in vermicompost:
Macronutrients
1.Nitrogen (N): 1.5-3.5% - essential for plant growth, leaf development, and protein synthesis.
2.Phosphorus (P): 1-3% - crucial for root development, flower and fruit formation, and energy transfer.
3. Potassium (K): 1-2% - important for overall plant health, resistance to disease, and water balance.
Micronutrients
1. Calcium (Ca): 1-5% - essential for cell wall development, root growth, and nutrient uptake.
2. Magnesium (Mg): 0.5-1.5% - crucial for photosynthesis, cell wall development, and nutrient uptake.
3.Sulfur (S): 0.5-1.5% - important for protein synthesis, plant defense, and nutrient uptake.
4. Iron (Fe): 0.5-1.5% - essential for chlorophyll production, photosynthesis, and plant growth.
5. Zinc (Zn): 0.05-0.15% - crucial for plant growth regulation, protein synthesis, and disease resistance.
6. Copper (Cu): 0.05-0.15% - important for plant defense, enzyme activity, and nutrient uptake.
7. Boron (B): 0.05-0.15% - essential for cell wall development, plant growth regulation, and nutrient uptake.
8. Manganese (Mn): 0.05-0.15% - crucial for photosynthesis, enzyme activity, and nutrient uptake.
Other Beneficial Compounds
1. Hormones: Vermicompost contains plant growth hormones like auxins, gibberellins, and cytokinins.
2. Microorganisms: Vermicompost is rich in beneficial microorganisms like bacteria, fungi, and actinomycetes.
3. Humic Acids: Vermicompost contains humic acids, which help improve soil structure, fertility, and water-holding capacity.
Vermicompost's nutrient profile can vary depending on factors like feedstock, worm species, and processing conditions. However, it is generally considered a rich and balanced fertilizer for plants.
