Clubroot problem is mainly showing up in the low pH soil of Alberta. Liming has been used as a control measure since the early 19th century. There is a close relationship between soil pH and Clubroot with acidic soils generally favoring Clubroot development.
SuperCal 98G pelletized lime a product which is 98% pure calcitic limestone, breakdowns rapidly and completely, thus raising pH in the first year has a good ft. According to the “Agriculture and Agri-Food Canada bulletin on Clubroot of Crucifers”, the scientific jury is still out on whether liming aids in disease control by raising pH or by increasing the calcium concentration.
We know that calcium is necessary for proper functioning of growing points particularly root tips. Also it forms compounds which strengthen cell walls and aids in cell division and elongation. Clubroot affects these processes in the plant.
Thus more research is needed to understand the effects of liming on Clubroot control and to establish additional recommendation. What is the effect of calcium placed in seed row or close to the seed building up local concentration as calcium is not easily translocated in plants, so a constant supply is required?

Gypsum is a product that contains 21% calcium and 17.5% sulfur, and has many benefits your soil. Gypsum interacts with water to reduce crusting. It loosens clay and compacted soil, improving the structure, aggregation and permeability which will allows for easier penetration of surface applied fertilizers. Gypsum increases soil calcium levels without affecting its pH. If your soil is high in sodium (or any other cation such as magnesium), it binds to the sulfur molecule in the gypsum. Since sulfur is mobile in the soil, it moves away from the root zone resulting in plant available calcium. This product also helps make phosphorous more plant available by attaching to the aluminum in the soil which frees up the phosphorous resulting in increased yields.

ENR would like to take this opportunity to congratulate Jason Trowbridge, one of our partners in the business, in completing both the International and Regional CCA exam. Jason’s experience and knowledge in agronomy strengthens our teams ability to continue the quest for solutions to increase production in local agriculture. Thank you for your hard work and dedication to agriculture.
Farmers are excited about the future of farming despite the lack of snow and moisture this winter. They are learning how to make the most out of their fields and environment by all the speakers here today including Terry Waddell from ENR.
Thank you Bruce Phos for the chance to speak with your clients, together we are growing the future of agriculture!
