Coffee? Just add Zintrac 700
In a 3 year project with the Coffee Research Institute, at Karnataka in India, Zintrac 700 was applied in line with traditional zinc sulphate rates and timings.
As the graph illustrates Zintrac 700 consistently outperformed zinc sulphate on the Arabica coffee variety. The average yield increase by using Zintrac 700 instead of zinc sulphate was 16% over the 3 years of trials.
This trials work follows up the independent Vietnamese coffee trials in 1997 on the Robusta variety. Phosyn´s zinc product gave statistically significant increases in coffee bean yield in Vietnam and showed why Zintrac 700 should be the zinc product of choice on the coffee crop.
