Abstract Controlled Release fertilizers (CRFs) are new generation agrochemicals which aid in decreasing
environmental pollution. In the present study, novel CRF beads are synthesized by the technique
of sol-gel polymerization. CMC polymer at various concentrations was used as a matrix and
kaolin was used as a binder to enhance mechanical properties of the beads. The study also
reveals the incorporation of Kaolin at different concentrations and optimization of the same.
Fe3+ was used as a cross-linker to obtain spherical beads. Also, a study was done to optimize
the cross linking time and concentration of cross linking solution. The usage of polymers… More >
