Anion Exchange Membrane Soil Nitrate Predicts Turfgrass Color and Yield

Turfgrass Reflectance Measurements, Chlorophyll, and Soil Nitrate Desorbed from Anion Exchange Membranes

1999) in a variety of locations and soil types. 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...

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...

Nitrate leaching from Kentucky bluegrass soil columns predicted with anion exchange membranes

Fall fertilization timing effects on nitrate leaching and turfgrass color and growth.

Fall season fertilization is a widely recommended practice for turfgrass. Fertilizer applied in the fall, however, may be subject to substantial leaching losses. A field study was conducted in Connecticut to determine the timing effects of fall fertilization on nitrate N (NO3-N) leaching, turf color, shoot density, and root mass of a 90% Kentucky bluegrass (Poa pratensis L.), 10% creeping red f...

High performance anion exchange ionomer for anion exchange membrane fuel cells

The anion exchange ionomer incorporated into the electrodes of an anion exchange membrane fuel cell (AEMFC) enhances anion transport in the catalyst layer of the electrode, and thus improves performance and durability of the AEMFC. In this work, a novel ionomer based on a triblock copolymer with high conductivity and good durability is synthesized successfully. The spectroscopy (such as H-NMR, ...
