Bullet Potassium Silicate 5L

Potassium Silicate will be deposited in cell walls where it increases turgidity, making cells more resilient to environmental stress, pests, turf diseases and improved stimp speeds. Silicon is one of the most abundant chemical elements in any soil but the vast majority is not available to plants. Silicon is particularly useful for grass plants, the addition of Potassium Silicate to turf crops can have a dramatically positive effect on growth and health.

Silicon treatments are protective, not curative, so need to be applied before the plant becomes stressed/attacked.

The silicon to carbon ratio (S:C) is extremely important to a grass’s ability to resist pathogens and drought stress. With increasing levels of CO2 in the air, this ratio has been compromised. Silicon is also now known to be key to resisting stresses related to urban locations, particularly ozone and heavy metal stresses which are common in built up or industrial areas. Bullet Potassium Silicate can be used to raise soil pH similar to liming with the additional benefits of crop protection.
