Data taken from our 2021 trial.
Comparing the nutrient uptake for the conventional and black oats, at first glance the conventional oats have taken up more of the macro nutrients.
Only with the uptake of calcium, have the black oats been more efficient than conventional. The phosphorus, magnesium and sulphur have all been fairly similar in uptake.
Looking at the micronutrients, the Black oats have a slight edge in uptake. This is mainly seen in the uptake of Zinc, but there is a small margin in the copper and boron as well. Molybdenum was omitted due to the very small amounts seen in both types of oat.
