Wollastonite at work in a Tropical No-Till System

Surface application of limestone and calcium-magnesium silicate in a tropical no-tillage system Research paper summary Although lime is currently the most commonly applied material for soil acidity correction in Brazil, calcium- magnesium silicate application may efficiently replace this source due to its higher solubility and silicon supply, which is beneficial for plant development. This study […]

Wollastonite in Water: A Clear Difference!

Last month, we discussed the role of wollastonite in managing phosphorus.

That prompted some Ontario residents to begin experimenting with adding wollastonite to pond water. With the recent heat and drought across much of the province, ponds and small bodies of water on farms, golf courses, and rural properties are especially subject to excessive algal growth – an unpleasant and unhealthy condition, as these photos demonstrate.

Wollastonite: A win-win for sustainable phosphorus management

In the summers of 2014 and 2015, massive algal blooms in Lake Erie made headlines across North America, particularly in 2014 when toxins produced by microcysts in the blue-green algae shut down Toledo’s water works, leaving hundreds of thousands of people without access to safe drinking water. The problem affects lake and rivers across the continent, threatening […]

Re-Blog: Silica – The Hidden Cost of Chemicals

Interest in the role of silicon in crop production and protection has been growing around the world for several years now. Some might say that North America is a bit behind the curve! We recently came across a comprehensive article from 2010 on the website of an Australian agricultural consulting company. It begins: A major mineral […]

A Natural Solution to Control Grub Damage?

Last summer, an interesting thing happened on a field of turf north of Toronto. The grower was testing a new soil amendment as a source of calcium, magnesium, and plant-available silicon. Research indicated it could lead to healthier, more disease-resistant grass. Sure enough, the grass on the test area grew better –  so much better […]

Video: Silicon, A Valuable Fungicide

Canadian Wollastonite isn’t the only organization doing research on the value of plant-available silicon in agriculture. Agriculture and Agri-Food Canada, in partnership with Laval University, and Les Fraises de l”Ile-d’Orléans is investigating how supplying soluble silicon to strawberry plants can increase resistance to diseases like powdery mildew and reduce the application of fungicides. Watch the […]

Introducing … Canadian Wollastonite!

Welcome to the Canadian Wollastonite blog. This is where we’ll share the latest information on our activities, whether they’re happening at the mine site, at research facilities, or on farms and gardens. In the first post, we’ll give a brief overview of our research activities and the on-farm trials that have been taking place over […]
