Cover crop trial book 21

Molybdenum uptake has been varied across both the straights and mixes. The Vetch and Buckwheat have the only positive uptake from the Poly treatment.

Key Points: Buckwheat has seen the best uptake across all elements with the Poly treatment. This has been around an 50% increase of uptake. Generally, uptake has been better from the single species with the Poly treatment, while the mixes have seen a negative effect. Untreated, the mixes have the better uptake. This could be down to the increased growth of certain elements in the mix, smothering out other important elements. This has particularly been seen with the Soil improver mix, and the Mustard taking over. This has meant that in the treated section, Mustard has been the only viable species, and has not seen the benefits of the uptake from other species in the mix.
