Affinity N- Vigorate is a highly loaded nitrogen source combined with fulvic acid. This combination is scientifically proven to increase nitrogin uptake and reduce nitrogen loss with volatilisation. 

​

Affinity N- Vigorate is a combination of nitrate and ammonium forms of nitrate that is critical for upfront and longer lasting nitrogen supply. The use of nitrate nitrogen is particularly critical where the nitrogen cycle is slow, mainly in poorly drained, cold or low organic carbon conditions.
