described low SOC content in Indonesia (Ave. = 1.39%, n = 44) resulting
from the widespread practice of burning rice straw at the end of the crop-
ping cycle. Our data reveals that SOC contents in the organic rice paddy
soils were higher than in the conventional managed soils, due to appropri-
ate organic matter input such as bochashi.
Organic farming helped to reduce the cost of rice production (Figure
4). For example, conventional farmers had to pay 1,410,000 Rp (rupiah)
for chemical fertilizers, while organic farmers only had to pay 30,000 Rp
for the bochashi organic fertilizer. Therefore, organic farming could cut
90% of the total cost of rice production.
