Nitrate Leaching from Kentucky Bluegrass Soil Columns Predicted with Anion Exchange Membranes

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

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...

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...

Denitrification Losses from Kentucky Bluegrass Sod

Denitrification may represent an important mechanism in the fate of N applied to turf. Denitrification losses were directly measured from fertilized 'Baron' Kentucky bluegrass (Poa pratensis L.) sod samples sealed in acrylic chambers using the acetylene inhibition technique. Losses were correlated with soil texture, percent soil sat· uration (SAT), and temperature. Losses from turf on a Hadley ...

Electrodialysis Heterogeneous Anion Exchange Membranes Filled with TiO2 Nanoparticles: Membranes' Fabrication and Characterization

In the current research, polyvinylchloride based mixed matrix heterogeneous anion exchange membranes were prepared by a solution casting technique. Titanium dioxide nanoparticles were also utilized as inorganic filler additive in the membrane fabrication. The effect of TiO2 nanoparticles concentration in the casting solution on the membrane physico-chemical properties was studied. Membrane wate...
