Our friends the earthworms

Tea plantations that use organic methods avoid all conventional pesticides and fungicides. They limit the spread of undesirable elements through the use of natural predators or repellents. And to enrich the soil, to make up for the nutrients that the tea plants take up, especially in intensive farming, they need to add a significant amount of organic matter. Organic compost can be bought in, or even better, produced on the plantation. One way of doing this is using vermiculture, a fairly common practice in India. Millions of earthworms are fed cattle manure mixed with chopped up banana leaves, for example. The worms produce excrement, and it is this excrement that is deposited around the base of each tea plant.
