* The above tables are examples only using the average nitrogen responses obtained from independent and in-house scientific fully replicated pasture trials.
The average pasture response of 24KG of dry matter per KG of Nitrogen applied was obtained from using 40KG of dissolved urea (18.4KG N) in Donaghys N-Boost system. Using less or more nitrogen from dissolved urea or other sources in conjunction with Donaghys N-Boost may also affect the pasture response. Due to temperatures, weather, soil conditions including available nutrients and other factors, pasture response from using Donaghys N-Boost may vary.
