Stubble burning in the fields. (file photo)
Punjab produces huge quantity of rice straw, which is a precious organic resource. It contains 0.5% N. 0.1% P205, 1.5% K2O, 40% carbon and 0.1% Sulphur. Rice straw of one acre contains about 20 kg N, 6 kg P205 and 40 kg K2O approximately. Burning of rice straw leads to the loss of nitrogen, sulphur and carbon as their oxides. Phosphorus is burnt partially. Burning not only the required nutrients but also the soil of cause environmental pollution. The oxides of nitrogen, carbon and sulphur cause global warming and lead to acid rains.
The residue can be handled efficiently and environment friendly ways. The residue can be removed from field and used for making good compost. It can be incorporated in the soil by direct in corporation. The residue can be managed by happy seeder machine, which plants wheat in standing stubbles.
The incorporation of residue will increase the organic carbon of soil in addition to other plant nutrients. The organic matters support the soil biota and improve physical and chemical properties of soil favourably.
Looking on above aspects, rice residue should not be burnt rather it should be managed efficiently to reach the soil.
