The company has extended its premium quality Peters range with Peters Excel CalMag Grower with Organic-S and Peters Excel CalMag Finisher with Organic-S.
It has also extended its standard Universol WSF brand with two new hard and two new soft water options.
Everris marketing manager Dave Steward said the new formulations delivered solutions to complete plant nutrition in soft water.
"As a result of increased rainwater harvesting, we are seeing rising soft water usage on UK nurseries," he said. "Soft water is very low in dissolved nutrients. Meanwhile, as a consequence of reducing atmospheric pollution sulphur levels have fallen significantly. Historically sulphates have been used to supply sulphur in WSFs but also contribute to conductivity and compete with other nutrients."
The stand will also showcase products including nutrition software tool AngelaWeb and controlled release fertilizer Osmocote Topdress NT.
Four Oaks Trade Show takes place in Cheshire on 2nd and 3rd September.
