Trials 2003
Following intensive research and field scale trials using micronutrients, the results showed such promise, that we embarked upon small plot trials to investigate further into the role of nutrition in cereal disease control.
In 2003 some 1000 small plots were established, consisting of 40 varieties, 20 of which were replicated.
Superimposed onto the replicated and randomised plots were different micronutrients. Phosphite, manganese, magnesium, copper and boron were all researched and assessed for various traits not only their inherent yield enhancing qualities. All plots were taken to yield and quality assessments made, the results of which highlighted the ability of micronutrients to 'energise' the plant to combat disease and in doing so maintain 'green leaf area' resulting in increased yield. Disease control was supplemented with reduced rates and mixtures of triazole chemistry. The mixture of triazoles proved to be critical, each ingredient having its owns speed of activity, disease profile and persistence giving us individual variety options and allowing for unique costing structure according to requirements.
From 'root mass' measurements and untreated plots since 2003 it has become apparent that phosphite is the key component of our strategy. Not only did we achieve an extra 22% root biomass but applied nutrition resulted in enhanced cost efficiency of nitrogen, potash and phosphate fertilisers.
