Where drilling of winter wheat has been delayed, the crop nutrition strategy should be adapted to help recover the lost yield potential, according to the latest advice from Yara. Charlotte Cunningham reports. For many, this autumn has been one of the worst on record with the persistent rain delaying drilling right across the country. In order to compensate against the effects of this, it’s essential that growers rethink their crop nutrition strategy, according to Yara’s Mark Tucker. “With delayed drilling of wheat crops come two issues. Firstly, the soil state as a growth medium is much poorer. Soil temperature drops by approximately two degrees per month and saturated soils clearly have less air spaces, reducing growth rates and nutrient availability. “Secondly over four weeks of the growth period has been lost. The latter is crucial as the fundamental for yield attainment is crop biomass (50% of this will go into yield).” Crop biomass development is crucial for yield One of the key components to achieving high biomass crops in May, June and July is the management of the early foundation stage of crop development, adds Mark. “A Yara crop nutrition strategy can be used as a remedy, helping to recover…
