Adding silicon to soil can help control clubroot in canola
Clubroot in canola can be reduced by up to 46% This article and study discuss the metabolic and physical changes that silicon provides canola. Silicon consistently shows improvements in plant metabolism enabling the plant to have more of the powerful molecules that attack the disease internally while at the same time silicon accumulates in cell walls to make them stronger. Cells hold the nutrients that diseases and pests need to access in order to grow and reproduce. Tougher cells greatly reduce the chances for a disease or pest to proliferate. Combined with a boosted immune system, silicon offers a double protection.
- Silicon fertilizer reduced incidence of clubroot 46%
- Article is unique in commenting on CO2 emissions associated with lime
- Authors suggest silicon’s protection works by changing gene expression and physically inhibiting the pathogen
- Lead researcher suggests wollastonite as a suitable source of silicon
- Compared with sodium silicate used in the experiment, wollastonite would increase the pH as well as provide abundant amounts of plant available silicon
