Sugar Cane

Calcium Silicate Benefits : Sugar Cane

Calcium silicates are emerging as one of the most effective sources of silicon in agriculture. Silicon is considered essential for sugarcane as it maintains the erectness of the plant, improves disease and pest resistance, and increases photosynthesis.

Sugarcane is a Silicon accumulator: an average crop can remove 100 to 175 kg/ha of silicon from the soil per average crop, and a very high yielding crop can contain over 250 kg/ha of silicon in the harvested biomass 1.

Flinders Agriculture’s Calcium Silicate is a unique product as it contains a high percentage of both Silicon and Calcium.
