Intercropping: Farmer R. Venkatrasa practises intercropping, the growing of two or more crops on the same field. Beneath coconut trees, fodder grasses are planted – hedge lucerne (Desmanthus virgatus) and CO4 hybrid napier grass . They not only provide food for cattle but contribute to nitrogen fixation (the conversion of nitrogen to ammonia, a compound of nitrogen and hydrogen that is necessary for plants to grow) .
Here are some features of an organic farm.
Superfood: Instead of commercial feed, cows and fish are fed azolla, an aquatic fern cultivated within the farm. The highly nutritious plant can beef up the growth of cattle and quality of milk. The fern lives in symbiosis with microscopic blue-green algae (Anabaena azollae, found in the cavities of the leaves). The algae fixes atmospheric nitrogen, allowing azolla to grow speedily. The fern can also be used as fertiliser.
