Wormcast, also known as vermicast, is a natural fertilizer produced by earthworms. It helps in improving soil fertility in several ways:

A. Enriching with Nitrogen: Wormcast is rich in nitrogen, a nutrient that is essential for plant growth. Nitrogen helps in promoting the growth of leaves and stems, and it is a major component of chlorophyll, the compound that plants use to convert sunlight into energy through photosynthesis.

B. Increasing Moisture: Wormcast has the ability to retain moisture, which is beneficial for the soil. Moisture is necessary for the germination of seeds and the growth of plants. By increasing the soil's moisture content, wormcast helps in improving its fertility.

C. Increasing Soil Air: Wormcast can improve the soil structure, making it more porous. This increases the soil's air content, which is necessary for the roots of plants to breathe. It also allows for better drainage, preventing water-logging.

D. Making it Dry: This is not a way in which wormcast helps in improving soil fertility. On the contrary, as mentioned above, wormcast helps in increasing the soil's moisture content.

So, the correct answer is A, B, and C. Wormcast helps in improving soil fertility by enriching it with nitrogen, increasing its moisture content, and increasing its air content.
