| Research Abstract |
Application of poly-silicate iron (PSI) sludge derived from water purification plants, unused waste, improved rice yields and brown rice quality, and decreased pecky rice damage caused by rice-feeding bugs in the organic rice farming system. PSI sludge and silicate application were effective in increasing rice root elongation and activity. PSI sludge showed the potential of decreasing methane emission in the organic-applied paddy soils. Application of PSI sludge and silicate fertilizer can contribute to establish the technology of environment-friendly paddy agriculture.
