There are many benefits of using rice husks in vineyards
First, application method
Start by thoroughly mixing rice husks with topsoil and fertilizer, then fill the mixture back into the planting pit. Apply approximately 1,500 kg per 667 square meters. After one month of grape sprouting, spread a layer of rice husks about 1 to 1.5 cm thick over the ground surface.
Second, benefits of using rice husks
Rice husks significantly improve soil structure, enhance water infiltration, and promote healthy root development, which in turn accelerates seedling growth. They also help regulate soil temperature, encouraging microbial activity that speeds up the breakdown of organic matter, effectively enriching the soil. Additionally, they provide insulation and stability—helping to shield plants from intense summer sun and reducing heat stress. Each 50 kg of rice husks typically contains about 0.16 kg of nitrogen, 0.05 kg of phosphorus, and 0.29 kg of potassium. When decomposed, they become a rich source of organic fertilizer, increasing the overall nutrient content of the soil.
Third, important considerations
When applying rice husks, it's crucial to follow the recommended quantities. Using too much can lead to excessive heat buildup, potentially damaging plant roots. The thickness of the mulch should vary with the season—apply it thinner in early spring and thicker in early summer. If heavy rain occurs, make sure to lift the rice husks slightly to prevent them from becoming compacted and hindering root growth. In areas where rice husks are not available, alternatives such as wheat husks, sorghum husks, crushed peanut shells, or sawdust can be used effectively.
By following these guidelines, you can maximize the benefits of using rice husks in your agricultural practices while ensuring the health and productivity of your crops.
