Maximising nitrogen efficiency with Pro+ Nviron PCA
As growers face increasing pressure to improve nitrogen efficiency and maintain yield whilst reducing traditional inputs under variable conditions, the role of biostimulants and foliar nutrition is becoming more critical.
Pro+ Nviron PCA is a next-generation approach to foliar nitrogen delivery, combining controlled-release nutrition with biostimulant technologies to support crop performance and return on investment.
Nitrogen remains one of the most important nutrients for yield-driving, but it is also one of the least efficient. Losses through leaching and volatilisation mean that a significant proportion of applied nitrogen is never actually utilised by the crop, reducing ROI.
This challenge is made even more significant if:
- Dry soil conditions limit nutrient availability
- Variable weather patterns affect uptake
- Regulatory pressure impacts fertiliser use
In this context, improving NUE is not just about reducing traditional inputs, it is about ensuring crops can access and utilise nitrogen effectively when they need it most.
Pro+ Nviron PCA is a controlled-release nitrogen product, designed to deliver nutrient steadily over a prolonged period. Nitrogen is released over 6–8 weeks, meaning that it better meets crop demand and reduces losses.
The result is improved nitrogen availability during key growth stages, reduced reliance on soil moisture for uptake and greater consistency in crop nutrition. Rather than a single application of nitrogen in one go, crops receive a sustained supply, supporting steady growth and increased biomass development.
While nitrogen supply is critical, utilisation within the plant is equally important. Pro+ Nviron PCA also includes pidolic acid, a key signalling compound in the nitrogen assimilation cycle. Under normal conditions, pidolic acid enhances the conversion of nitrogen into amino acids and proteins and supports efficient plant metabolism and growth.
Under stressed conditions, it helps prevent the accumulation of toxic ammonia and maintains nitrogen assimilation when crops would otherwise slow down.
Research shows that pidolic acid can sustain nitrogen metabolism for up to three weeks post-application, helping crops continue growing through short periods of stress.
Alongside pidolic acid, Pro+ Nviron PCA integrates biostimulant components that support:
- Improved nutrient uptake efficiency
- Enhanced cell division and growth
- Better utilisation of applied nutrients
Across a range of crops, controlled-release foliar nitrogen systems have demonstrated 85–95% nitrogen use efficiency, improved crop safety, enhanced compatibility with tank mixes and consistent yield improvements despite variable conditions.
In maize, trials have shown improved biomass and yield even at reduced nitrogen rates, highlighting the importance of timing and availability rather than total input. In oilseed rape and potatoes, applications at key growth stages have supported canopy retention and overall yield performance, particularly where soil-driven uptake is limited.
As agriculture continues to react to a changing climate and increasingly difficult conditions, the focus is shifting from input quantity to input efficiency.
