​Rain-Soaked, Distressed Maize Will Benefit From a Nutritional Boost
By Dr Simon Pope 16 days ago

Dr Simon Pope, Wynnstay crop protection manager, is urging growers to give some careful thought to the nutrition of their maize crops, following days of torrential rainfall in June, to ensure a maximum return on investment in 2019’s harvest.

This summer has so far been a washout, with a deluge of daily heavy rainstorms resulting in widespread flooding throughout most of June.

This has left many maize crops visibly stressed. The cold, wet soil conditions have affected root development which, in turn, will impact on nutrient uptake. Maize needs 50% of its total nitrogen requirement from the eight-leaf stage to tasselling and will benefit from a bit of extra help this season.

Dr Pope says, “We don’t really know what all this water has done to the nutrients available to the plant but it certainly will not have helped the crops to achieve their full yield potential. “Even in a more ‘normal’ season, by the time we reach July, there is little nitrogen remaining from seedbed applied fertiliser and an application of N Durance 28 between now and the end of the month, can really give the crop a boost.

“This year, the additional nutritional lift from an application of slow release liquid foliar nitrogen could pay dividends. Increases in fresh yield of 10% and of 9% in starch yield have been recorded as a result of applying this product.

“Usefully, N Durance 28 can be applied in conjunction with fungicides, so in areas prone to Eyespot, the two jobs can be tackled in one pass.” Temperatures are starting to rise at last and the Met Office’s three-month forecast predicts that for the period from June through to August as a whole, the probability that UK average temperatures will fall into the warmest of its five categories is 45-50 per cent.

2018 was the joint hottest summer on record for the UK and the hottest ever for England, according to the Met Office. Highs for summer 2018 were tied with those of 1976, 2003 and 2006, for being the highest since records began in 1910.
