Relationship of Turfgrass Growth and Quality to Soil Nitrate Desorbed from Anion Exchange Membranes

do not completely contact the soil. Furthermore, it is possible that the adsorption of ions by resins is governed by Anion exchange membranes (AEMs) are a potential method for two distinct diffusion coefficients, an internal and an exdetermining the plant available N status of soils; however, their capacity for use with turfgrass has not been researched extensively. The ternal coefficient (Coop...

The AEM technique, however, may be more sensitive than tradiThere is not extensive research on the potential of anion exchange tional extractions to treatment differences at low soil membranes (AEMs) for determining available N in soils of turfgrass NO3–N concentrations (Pare et al., 1995; Wander et al., systems, nor on the use of reflectance mete...

Quantifying turfgrass-available N from returned clippings using anion exchange membranes

Returning clippings can provide N to turf, but the amount of plant-available N derived from clippings is not easy to quantify. An accurate estimate of N released by clippings would be useful in guiding turf N fertilizer recommendations. The objective of this study was to determine if anion-exchange membranes (AEMs) could be used to quantify plant-available soil N when clippings are returned. A ...
