Modeling Phosphorus Capture by Plants Growing in a Multispecies Riparian Buffer

Table 5

NST 3.0 model estimates of phosphorus uptake in kilograms per hectare for four depth increments at the end of a 126 d simulated growing season for buffers composed of cottonwood, switchgrass, and smooth brome.

Plant community	Depth of soil increment (cm)
	0–120	0–30	30–60	60–120
	kg P ha^−1
Cottonwood	24.5	20.4	2.7	0.8
Switchgrass	21.5	15.3	7.3	4.7
Smooth brome	21.4	18.8	5.4	2.0
