CPM talks to a soil scientist who believes he’s developed a system which enables a more finely-tuned approach to feeding the crop’s potential. The analyses behind RB209 aren’t sufficient to predict accurate fertiliser needs. By Lucy de la Pasture As the major R&D institutes concentrate more and more on molecular research programmes, much of the applied research is being carried out by innovative growers and entrepreneurial scientists in on-farm trials. It marks a sea change from the way things used to done, with trials data obtained from real commercial situations which enables fast transfer of technology into actual practice, says Simon Fox, soil scientist and founder of Emerald Research, based in Glos. Simon Fox says the system uses RB209 as a guide to the amount of base fertiliser, but overlays this with output from the OptiYield model. One of the puzzles facing agronomists is how to meet the crop’s nutritional needs and get the most benefit from using biostimulant products. While their potential is exciting, deciding how and when to use them is proving…
