Silicon availability in terrestrial soils (especially those used in intensive agriculture) is potentially declining due to effects of ecosystem management, and the yearly withdrawal by crop harvest (given that many crop plants are Si accumulators). Silicon is the perfect background element for BioGuano+ and serves numerous purposes. Cells are the building blocks of a plant’s framework. Silicon can increase the rigidity of plant cell walls and strengthen branches to better support large fruits and flowers associated with modern plant genetics. Stronger cells form thicker stems. The thicker cell walls create bigger stalks with bigger pathways that uptake and transport more water and more nutrients. This fortifying, synergistic effect will help to facilitate bigger plants, faster growth, and protection against sap sucking insects. Plants also express increased resistance to various pathogenic fungi such as grey mould and powdery mildew.

Silicon is also used to stabilise and increase the dispersion rate of BioGuano+. This stops it inherently sticking to itself after the fine milling process, which ensures more consistent application is achieved.
