To increase grower awareness of the benefits of applying Lime to a cropping operation. Providing local relevance to farmers.

Soil acitidy is affecting grain yield. 2014 investigation of a farmer led onfarm lime trial clearly identified the benefits of applying agricultural lime. The farmer applied 3 rates of lime and left 2 control strips. Both limed and control strips were soil cored and the pH within the soil profile was identified at depth for 5 individual sections. Results demonstrated that where the maximum rate of lime was applied, the soil pH within the profile was appropriate for plant growth. Where no lime was applied soil pH was significant enough to impact upon plant growth. Biomass cuts taken at Anthesis, from both the limed and control strips, showed a correlation between soil pH and plant growth. Grain samples taken from both the limed and control strips prior to harvest also showed a correlation between grain yield and soil pH. Where soil pH was above 5.5 plant growth and yeild was highest.
