Alternative uses of rice stubble Report
The rice stubble dilemma
Rice crops produce a significant amount of stubble (in rice 12 t grain = 15 t straw) which provides many challenges. Burning stubble is a quick fix with minimal cost that enables good establishment of the following crop. However burning is perceived as being detrimental to the environment and nutrients and organic matter are lost from the system. Stubble smoke can also impact on third parties. The uptake of alternative management practices to burning involves justifying the significant extra costs of the machine operations involved against the soil health benefits and the resultant environmental benefits.
