Rice, along with sugar cane is a know accumulator of soluble silicon from the soil matrix. The rice plant accumulates most of the soluble silicon in the stalk to help with rigidity (which in turn promotes better photosynthesis) and in the hull which helps protect the grain from damage.
There is over five decades of science that proves rice is dependent on good levels of plant available silicon in order to remain healthy. Most major rice growing nations such as China, Japan and Vietnam are aware of the problems caused by silicon deficiency and routinely add silicon to their rice crops.
MaxSil™ was trialled on rice in the Hay region in 2009 and the response was extremely positive. Further trial work was suspended until recently when a more durable pelletised material (rather than the powder originally used) was developed for this application.
MaxSil™ is being applied this season to rice crops across the Riverina at application rates of 100 kg per hectare.
