Combining organic and inorganic fertilizers: recommended practice for sustaining rice yield: Rice Science for Decision-Makers

A PhilRice study (1993-2012) on continuous application of organic and inorganic fertilizers on irrigated rice shows that achieving nutritional balance between these two inputs results in better soil productivity and functionality than using either of them singly. The study also looked at farmyard and household wastes as alternative source of fertilizer for rice crops.
