Nitrogen uptake and leaching from urine and fertilizer applications during simulated grazing rotations of a perennial grass pasture

The productivity of grazing-based dairy systems is driven in large part by availability of nitrogen (N) as it cycles though the soil, plant and animal. However, N use efficiency (NUE) is generally less than 40 % with significant N losses attributed to animal excreted N, especially urinary N, due to...
