Post-rain growth flush: 12 mL from water, 8 from mineralized soil N, & 2.5 from N in the rain
This is about partitioning the growth flush after a rain. What's causing that growth flush? I made some calculations, using New Forest GC in the UK as an example. The increased soil water content from a 20 mm rain, in this example, would increase daily clipping volume from 10 mL/m2 to 22 mL/m2, a 12 mL increase.
