However, ADAS senior crop research scientist Dr Christina Baxter says using the RB209 target level metric alone doesn’t indicate the amount of phosphate in available or unavailable forms. Therefore, cross-referencing this with grain analysis will offer a broader picture of how well the crop is accessing the available phosphate, indicate limitations and allow offtake to be calculated. “It’s a chicken and egg scenario as the crop must forage to…
