REMEMBER Carravita, the fertilizer additive that we featured in this blog just a few days ago? The latest report is that the Department of Science and Technology is partnering with the Department of Agriculture so that Carravita will be field tested in 4,000 hectares of farmers’ rice fields in the next planting season.
Carravita is derived from carrageenan or seaweed. The research using carrageenan as fertilizer additive was based on an earlier study conducted by the Philippine Nuclear Research Institute, an agency of DOST. Carrageenan was subjected to irradiation to degrade the substance into minute particles so that it can be readily absorbed by the plants.
