Pro+ Nviron PCA is a rainfast, low scorch, highly efficient controlled release foliar nitrogen which combines the proven biostimulant Pidolic Acid (PCA), Urea and Polymer Urea for improved nutrient use efficiency. Pro+ Nviron PCA releases nitrogen over a 6-week period, whilst pidolic acid improves nitrogen assimilation and increases growth and yield.
The traditional granular nitrogen fertiliser market is under severe pressure. Climate change is causing frequent drier springs which reduces efficacy and increases greenhouse gas emissions. This, combined with current turmoil in the fertiliser market driven by high gas and energy prices is forcing the market to look for new, higher efficiency foliar nitrogen solutions. Pro+ Nviron PCA is exactly that; a controlled release Nitrogen combined with a plant biostimulant for increased nutrient use efficiency.
Pro+ Nviron PCA improves NUE in two ways: slowly releasing nitrogen over a 6 week period and improving nitrogen assimilation through signalling compound pidolic acid. The NUE of traditional soil applied fertilisers can be as low as 30% but is typically 50%. In contrast, Pro+ Nviron PCA offers up to 95% NUE.
When to use Pro+ Nviron PCA varies depending on the crop and environmental conditions. For example, optimal results in oilseed rape to increase yield Pro+ Nviron PCA is applied at 20L/ha at BBCH70 (10% pod formation), but if it is dry early in spring, then an additional application of 20L/ha could be considered at BBCH51 (green bud). Pro+ Nviron PCA can be used as part of a yield building sequence including Talisman and Incite.
Wide range of crops.
What makes Pro+ Nviron PCA different from traditional nitrogen fertilisers?
Pro+ Nviron PCA is a rainfast, low scorch foliar nitrogen that releases over 6 weeks. Unlike granular fertilisers, it delivers nitrogen more efficiently, with up to 95% nutrient use efficiency (NUE) compared to 30–50% for typical soil-applied nitrogen.
Which crops can benefit from Pro+ Nviron PCA?
Pro+ Nviron PCA can be used across a wide range of crops, including cereals, maize, oilseed rape, sugar beet, potatoes and many vegetables. Application timing varies depending on crop growth stage.
How does pidolic acid enhance Pro+ Nviron PCA performance?
Pidolic acid acts as a signalling compound to improve nitrogen assimilation, supporting increased amino acid and protein production, improved growth and higher yield potential.
When is the best timing for Pro+ Nviron PCA application?
Can Pro+ Nviron PCA reduce environmental impact compared to conventional fertilisers?
Yes. With higher NUE and reduced volatilisation losses, Pro+ Nviron PCA ensures more nitrogen is used by the plant, lowering the risk of leaching and greenhouse gas emissions.
Is Pro+ Nviron PCA safe to use in hot or dry conditions?
Its low scorch formulation provides excellent crop safety, even in challenging weather conditions. However, for optimal uptake, avoid spraying during the hottest part of the day.
Can Pro+ Nviron PCA replace granular nitrogen entirely?
Pro+ Nviron PCA can be used as part of the nitrogen programme, depending on crop needs and environmental considerations. It is especially valuable where granular application is less effective, such as in dry springs.
Is Pro+ Nviron PCA compatible with other products?
Yes. It has wide tank-mix compatibility with many crop protection and nutrition products, making it easy to integrate into existing spray programmes.
How does Pro+ Nviron PCA contribute to yield stability?
By combining slow-release nitrogen with biostimulants, Pro+ Nviron PCA ensures a steady nutrient supply, stronger photosynthetic performance, and greater stress resilience, helping maintain yield potential even in variable growing conditions.
