The benefits of rice husks include soil improvement (improved aeration, better drainage, soil softening), heat and moisture retention, suppression, silica supply, and recyclability as a resource. Rice husks are a readily available material that can be obtained for free, and their major advantage is their diverse functions that improve soil physics and promote crop growth.
Main Benefits
Soil Improvement Effects:
Improved Aeration and Drainage: The gaps in rice husks supply air to the soil and improve drainage.
Soil Softening: Especially when mixed with clay soil, it softens the soil and makes it easier for roots to grow.
Improved Water Retention (after charring): Rice husk charcoal (kun-tan), made from charred rice husks, enhances soil water retention and provides a habitat for soil microorganisms.
Heat and Moisture Retention Effects:
Stabilized Soil Temperature: Spreading on the ground surface protects the soil from sunlight and outside air, suppressing rapid changes in soil temperature.
Moisture Retention: Suppresses moisture evaporation from the ground surface, preventing soil from drying out.
Suppression Effect:
Spreading on the ground surface blocks sunlight and suppresses growth.
Silica Supply:
Rice husks are rich in silica, which is said to strengthen plant stems and leaves when absorbed by crops.
Value as a Resource:
Since large quantities are produced every year, it is a reliable material that can be used as an alternative to finite natural resources.
In addition to soil improvement, it can be used for various purposes such as livestock bedding and drainage materials.
