Rice plants (Oryza sativa L.) contain large quantities of silicon (Si) in form of phytoliths, which increase their resistance to abiotic and biotic stresses. The Si cycle through rice fields is hardly studied. We tested how increasing Si availability affects rice growth and the decomposability of the straw. Secondly we tested the role of straw recycling for Si availability. In a field experiment, we applied three levels of silica gel during one rice cropping season. In a follow-up laboratory… CONTINUE READING
