How to avoid the top 5 nutrient deficiencies in OSR.

Correcting micronutrient deficiencies in oilseed rape can raise yields by an average 0.3t/ha, according to trials, helping growers get even more from a crop that is proving to be increasingly expensive to grow. Yara leaf tissue tests collated at its Pocklington lab in 2019 revealed that 70% of the 6,479 samples were deficient in boron, 60% in magnesium, 30% in manganese and 15% in molybdenum. Half of the soils tested were deficient in manganese, illustrating that some farmers are routinely applying this nutrient, while 75% were deficient in boron, closely matching the tissue test.
