Silicon Produces Significant Yield Increases in Sugar Cane
By: Sugar Research and Development Corporation and CSIRO
The trials were conducted over a variety of locations across Queensland cane growing areas.
Materials used were a number of calcium silicate slags, cement kiln dust, wollastonite, diatomaceous earth, mill ash (from cane stalk furnaces), a liquid potassium silicate, acidulated serpentine
The trial work was dedicated to sugar cane.
- “Demonstrated significant yield responses were recorded” after additions of silicate material to sugar cane crops.
- In Innisfail there was “a 32% increase in yield, at Mossman a 35% increase and in Bundaberg a 23% increase over the controls” with crop cycles of two to three years.
- The same trial work showed that “the calcium silicate materials improved the nutrient exchange capacity (the cation exchange capacity) of the soils they were applied to”.
