Simultaneous removal of ammonium and nitrate by HDTMA-modified zeolite

In this study, surfactant (hexadecyltrimethylammonium, HDTMA) modified zeolite (clinoptilolite) (SMZ) was used for simultaneous removal of ammonium and nitrate in wastewater, and the sorption properties of SMZ were determined. Results showed that natural clinoptilolite had good affinity for ammonium, but low sorption ability for nitrate, and the ammonium sorption process was well described by ...

Evaluation of nitrogen sources and application methods for nitrogen-rich reference plot establishment in corn

Five different N sources were compared with null N treatment to evaluate their performance for N-rich reference plot establishment in corn (Zea mays L.). The sources, including calcium ammonium nitrate (CAN), urea ammonium nitrate (UAN), polymer-coated urea (PCU) and environmentally smart nitrogen (ESN) in 2007 and 2008, and urea (URE), were broadcast or in-soil banded at the rate of 225 kg N ...

Uptake of point source depleted 15n fertilizer by neighboring corn plants

Ground-based active (self-illuminating) sensors make it possible to collect canopy data that are useful for making on-the-go N fertilizer application decisions. These technologies raise questions about plant-to-plant competition for targeted fertilizer N applications. This study evaluated the extent to which fertilizer N applied to an individual corn (Zea mays L.) plant might be intercepted by ...

Growth and nitrogen fixation in high-yielding soybean: Impact of nitrogen fertilization

In high-yielding soybean [Glycine max (L.) Merr.] environments, N uptake during seed-filling may be constrained when the late-season decline in biological nitrogen fixation (BNF) is coupled with insufficient soil N. Three N-fertilization strategies were compared with a control (N0) on soybeans in 2006 and 2007 in a high-yield soybean-maize (Zea mays L.) rotation experiment established in 1999. ...

Green tea catechins applied to susceptible hosts inhibit parasitic plant attachment success

Parasitic plants utilize cell wall degrading enzymes (CWDEs) to penetrate their host plant and attach to host vasculature. Inhibition of CWDEs may confer resistance on susceptible hosts, offering a strategy for parasitic plant control. Here, exogenous application of green tea catechins, which inhibit pectin methylesterase (a CWDE), was used to delay parasitic plant attachment. Texas bluebonnet ...

Nitrogen source and rate effects on the establishment of ‘TifSport’ and ‘Tifway’ hybrid bermudagrass

In the southeast United States, the most popular vegetatively propagated hybrid bermudagrass (Cynodon dactylon x C. transvaalensis Pers. L.) has long been the cultivar Tifway. In recent years, however, southern turf managers choosing cultivars for lawns, golf course fairways, or athletic fields have a newer option: ‘TifSport’ hybrid bermudagrass, also a vegetative selection. Although the use of ...

Equivalency of broiler litter to ammonium nitrate as a cotton fertilizer in an upland soil

Estimates of litter value based on crop yield equivalency to inorganic fertilization may reflect the actual value of litter more accurately than estimates based on its N, P, and K content. The primary objective of this research was to identify a rate of broiler litter that results in cotton lint yield equivalent to inorganic N fertilization and to estimate litter value based on this yield ...

Potato response to a polymer-coated urea on an irrigated, coarse-textured soil

Controlled release fertilizers, especially polymer-coated urea (PCU), have been shown to reduce nitrate (NO3) leaching while maintaining potato (Solanum tuberosum L.) yields, but cost has been prohibitive. A new type of PCU (Environmentally Smart Nitrogen, Agrium, Inc., Calgary, AB) is less costly than previous PCUs, but its effectiveness on potato production has not been extensively studied. A ...

Cattle manure application strategies effects on bahiagrass yield, nutritive value, and phosphorus recovery

Animal manure application based on crop N requirements often leaves excess P in the soil because of the differences in the N/P ratio in manures and that required by the plants. This experiment was designed to evaluate the effects of cattle (Bos taurus) manure applied alone or in combination with ammonium nitrate (AN) on bahiagrass (Paspalum notatum Flügge) dry matter (DM) yield, nutritive value, ...

Tillage and fertilizer effects on yield, profitability, and risk in a corn-wheat-potato-wheat rotation

Reduced tillage results in lower production costs and thus may have economic advantages for farmers. However, yield penalties, specific yield risks, or higher nutrient requirements may counteract the positive effects of reduced tillage. This study investigates long-term tillage effects (moldboard plow, and deep and shallow chisel plow) and their interactions with N fertilizer input on yields and ...
