OMEX can help…..

The lack of adequate rainfall in most areas of the UK since March means that many winter, spring and perennial crops are now under drought stress, especially on lighter soils, and could benefit from foliar fertiliser application. Cumulative rainfall totals so far for May range from 5% of the monthly long term average (LTA) in south-east England to 16% in north-east England.

Often during the summer period nutrient absorption by roots is decreased in plants when under water stress, even when there is an adequate supply of soil-applied fertiliser. This can impair seed, fruit or tuber development resulting in reduced quality and yield. Foliar nutrition can be an effective delivery method to ensure that plants receive vital nutrients during this critical development period [1].

SAP analysis can be helpful to determine if there are particular severe deficiencies that need to be addressed, but if a more immediate response is needed there is no better drought stress-buster than OMEX Bio 20. The proven all-in-one combination of nutrients and a powerful biostimulant is excellent at maintaining plant growth during situations of abiotic stress.

Bio 20 is physically compatible with most crop protection inputs and can be combined with standard fungicide applications, but try to avoid making any foliar input applications during the hottest part of the day and in strong direct sunlight as this can result in further leaf damage. Better uptake will result from applications made in cooler, duller conditions with higher humidity such as the early morning or at the end of the day.
