SUPPRESSIVE soils are soils that contain a high level of beneficial microbes that compete with pathogenic microbes therefore suppressing the build-up of pathogenic inoculum in the soil to infect vulnerable crops.
Suppressive soils are normally characterised as soils with a decent amount of organic matter or available carbon, a carbon to nitrogen ratio around 11, a balanced structure with neutral pH and therefore containing a balanced ratio of the cations in exchangeable form: calcium, magnesium, sodium, potassium and hydrogen, and an adequate and balanced amount of nutrients to sustain strong healthy plant growth.
It has been know for many decades that calcium, cyanamide fertiliser creates highly suppressive soils assisting growers in overcoming soil-borne pathogen build-up and delaying early weed invasion of crops.

These effects are of high value to growers and combined with a high level of non-leaching nitrogen that is all available and feeds as ammonium for an extended period of time and the highest level of available calcium of any fertiliser, crops thrive when grown on it.
Now there is a product that has been specifically designed to improve these effects and create suppressive soils to assist growers overcome soil-borne diseases more effectively and in a more organic way.
By combining calcium cyanamide granular (Perlka) with a special organic NPK fertiliser, Australian Agricultural Marketing Organisation has developed Calcium Organomide NPK + te.
Designed to specifically create a suppressive soil against soil-borne pathogens this new and special fertiliser, Calcium Organomide NPK + te, is the logical step towards growing low-cost healthy crops and vastly improved soil health.
High in Calcium and four forms of nitrogen, the product is a new tool for intensive vegetable production with produce grown without the need of chemical fertiliser salts such as calcium nitrate and chemical based NPK fertilisers.
