Alginate microcapsules/microparticles loaded with biological agent (biofertilizers) and chemical agents (macro- or micronutrients) for agroecological production

Trends of encapsulation in agriculture are focused on the preparation of microparticle formulations involving biological and chemical agents. The main problems that should be solved here are: (i) to choose microparticle that can incorporate biological and chemically active agents and (ii) the presence of active agents in the same compartment should not diminish their activities. Due to benefits of crop protection and nutrition as well as high compatibility, Trichoderma viride spores (biofertilizers) and copper or calcium cations (micro- or macronutrient) were taken as a suitable couple of the chemical and biological agent. We have developed and characterized alginate microspheres and microcapsules (with chitosan layer) prepared by the ionic gelation using copper or calcium cations as a crosslinking agent and loaded with T. viride spores. Simultaneous loading in microparticles revealed that presence in the same compartment does not inhibit bioactivity either of T. viride spores nor gelling cations.
