Farmers can use devices such as mulchers (that cut up grass, leaves, etc., for use as mulch), rotavators (a machine with rotating blades for breaking up or tilling the soil), Happy Seeders and straw management system to manage and utilise stubble.
Happy Seeder is nothing but a tractor-mounted device which can cut and lift the previous crop (in this case the rice straw) and sow a new (wheat) crop in its place simultaneously. It also deposits the straw over the sown area as mulch. Mulch enriches and insulates the soil.
The straw management system involves the use of a machine attached to a harvester chopper, which spreads loose straw uniformly. Here, the straw serves as mulch.
Straw could also be used as feeder.
(However, farmers in these regions report a lower preference for paddy straw because of the comparatively high silica content in it. There are also reports of wheat straw rejection due to fuel spillover during harvesting by machines.)
