After the rice harvest, many farmers use the leftover rice straw to cultivate mushrooms. Mushroom spores grow in the rice straw piles; with enough water and good care, the mushrooms will grow strong and healthy. The rice straw from 1000 m² and 12 bottles of mushroom spores are used. Spores are put into the straw and water is spread to develop the mushrooms. The farmers can collect 24 kilos of mushrooms in 15 days and receive a profit of 7000 VND/kilo. With costs calculated, farmers earn approximately 100,000 VND. Growing mushrooms is an easy job for farmers to quickly earn money. After the mushroom harvest, the rice straw can be used again as good fertilizer for all vegetables. Ánh Dương organizes training sessions about mushroom growing techniques to various communities.
