Download PDF The end of year report for amino acid biostimulants reads ‘could do better’. CPM finds out where the independent evidence suggests we’ve got to on the learning curve. We’re using biostimulants as a blunderbuss at the moment. By Lucy de la Pasture The buzz around biostimulants has reduced to more of a whisper. And that’s hardly surprising in a difficult year where inputs will be carefully considered with a careful eye on their probable contribution to the bottom line. Independent research is indicating that biostimulant effects are anything but certain. In 2017, ADAS conducted a review of the biostimulants market on behalf of AHDB and the overwhelming conclusion was that there’s a distinct lack of field evidence in the UK to properly assess the contribution this upcoming class of products may make to yields, explains ADAS crop physiologist, Dr Kate Storer. Interestingly, the review found one of the lowest evidence-base was for one of the classes of biostimulants that’s been gaining the most momentum on farm, amino acids. Researchers found the published data was principally from glasshouse pot experiments and there was little or no independent data for amino acid use in cereal or oilseed rape crops. In…
