Pushing the limits of fertilizer N recovery in a semiarid climate with improved N management
A common goal of N fertility programs should be to provide for the highest recovery of applied fertilizer N in the targeted crop species consistent with maximum yield and/or economic returns.
IPNI-2016-USA-MT19
Introduction and Justification A common goal of N fertility programs should be to provide for the highest recovery of applied fertilizer N in the targeted crop species consistent with maximum yield and/or economic returns. Fertilizer N is subject to a number of biochemical processes in the N cycle that limit its recovery in crops, including losses due to denitrification (DEN), leaching, and volatilization. Read more
Interpretive Summary
| 2017 | A common goal of nitrogen (N) fertility programs should be to provide for the highest recovery of applied fertilizer N in the targeted crop species consistent with maximum yield and economic returns. To improve fertilizer N recovery in semiarid climates, such as Montana, consideration should be given to the use of NBPT (urease inhibitor) with urea or inclusion of nitrate-N sources. |
| 2016 | A common goal of nitrogen (N) fertility programs should be to provide the highest recovery of applied fertilizer N in the targeted crop species, consistent with maximum yield and/or economic returns. Previous research in Montana’s semiarid climate has shown that fertilizer N recovery (FNR) can be improved by inclusion of nitrate fertilizer sources, and/or addition of urease inhibitors (such as NBPT) to regular urea (46-0-0). |
