To identify whether deep ripping and other soil treatments will result in an increase in spring water use by crops and therefore increased yields and improved grain quality.
The data would suggest that Deep Ripping had an effect on increasing the total water content of the soil, thereby making more moisture available to the barley crop during the spring months at a time when the crop was filling the grain. This may have resulted in a higher grain yield for both Ripped and Ripped + Gypsum treatments by comparison to the Direct Drilled and Shallow Cultivation treatments (although yield difference not statistically significant).
For further conclusions please see the attached trial report.
