Efforts have increased.to measure nitrate losses from farmland.und.r d.fferent management practices d.e to environmental and.public concerns over levels of nitrate-nitrogen (NO3-N) in surface and.ground.waters. This stud. evaluated.the effect of conventional tillage (CT) and.strip tillage (ST) practices and.three N application rates on NO3-N concentrations in soil water at a 76 cm d.pth und.r irrigated.sugarbeet (Beta vulgaris L.) in a clay loam soil. Nitrogen rates were applied.as d.y urea at 120, 150, 180 kg N ha-1 in 2006;130, 160, 190 kg N ha-1 in 2007;and.110, 140, 170 kg N ha-1 in 2008. Soil water volumes were measured.weekly d.ring each growing season using three ceramic suction cup samplers per plot placed.at a 76 cm d.pth below the soil surface und.r each tillage. Results ind.cated.that NO3-N concentrations at the 76 cm d.pth in the soil profile were not significantly affected.by either tillage practice or by N application rate d.e to soil variability across the field.and.d.e to suction cup samplers’ biased.estimate of soil water. The three N rates und.r CT and.ST practices maintained.NO3-N concentrations below the root zone to levels exceed.ng the 10 mg L-1 safe d.inking water maximum level in all three years. There were large variations in NO3-N concentrations among replicates within each tillage and.N rate that were likely caused.by variability in soil physical, hyd.aulic and.chemical properties that impacted.water movement through the soil profile, N d.namics and.leaching below the root zone of sugarbeet. In conclusion, suction cup samplers are point water measurement d.vices that reveal consid.rable variability among replicates within each treatment d.e to the heterogeneity of field.soils. Further, these samplers are not recommend.d.in heterogeneous soils with preferential flow characteristics.

In ad.ition to their value as cereal grains, wheat (Triticum aestivum L.) and.triticale (× Triticosecale Wittmack) are important cool-season annual forages and.cover crops. Yearling steer (Bos taurus) performance was compared.in the spring following autumn establishment as for age cover crops after soybean [Glycine max (L.) Merr.] grain harvest. Replicated.pastures (0.4 ha) were no-till seed.d.in three consecutive years into soybean stubble in autumn, fertilized. and.grazed.the following spring near Ithaca, NE, USA. Each pasture (n = 3) was continuously stocked.in spring with four yearling steers (380 ± 38 kg) for 17, 32, and.28 d.in 2005, 2006, and.2007, respectively. In 2005, average d.ily gain (Ad.) for steers grazing triticale exceed.d.the Ad. for wheat by 0.31 kghd.sup>-1d.sup>-1. In 2006, wheat Ad. exceed.d.that for triticale by 0.12 kghd.sup>-1d.sup>-1. In 2007, steers grazing wheat lost weight, while steers grazing triticale gained.0.20 kghd.sup>-1d.sup>-1. Based.on the 3-year average animal gains valued.at $1.32 kg-1, mean net return ($ ha-1 yr-1) was $62.15 for triticale and.$22.55 for wheat. Since these grazed.cover crops provid. ecosystem services in ad.ition to forage, grazing could.be viewed.as a mechanism for recovering costs and.ad.s ad.itional value to the system. Based.on this 3-year grazing trial, triticale was superior to wheat and.likely will provid. the most stable beef yearling performance across years with variable weather for the western Cornbelt USA.

In the presence of ethanol, alkylates d.grad.tion was not inhibited.by ethanol. However, alkylates d.grad.d.more slowly in the presence of BTEX suggesting competitive inhibition to microbial utilization of alkylates. In the sterile controls, alkylates concentrations remained.unchanged.throughout the experiments.

Soil bulk density and moisture content are dynamic properties that vary with changes in soil and field conditions and have many agricultural, hydrological and environmental implications. The main objective of this study was to compare between a soil core sampling method (core) and the CPN MC-3 EliteTM nuclear gauge method.(rad.ation) for measuring bulk d.nsity (ρB) and.volumetric moisture content (θv) in a clay loam soil. Soil ρB and.θv measurements were d.termined.using the core and.rad.ation method. at 0 - 10 and.10 - 20 cm soil d.pths. The mean values of soil ρB obtained.using the core method.(1.454, 1.492 g·cm−3) were greater than those obtained.using the rad.ation method.(1.343, 1.476 g

d.ar Ed.tor, Plant cells are encased.by cell walls--rigid.yet highly d.namic composite structures, which consist of cellulose, hemicelluloses, pectic polysaccharid.s, glycoproteins, and.the polyphenol lignin （Somerville et al., 2004）. Biosynthesis of the wall polysaccharid.s is facilitated.by d.nor- and.acceptor- substrate-specific glycosyltransferases catalyzing the transfer of the sugar moiety from a nucleotid. sugar to form a specific glycosid.c linkage. Glycosyltransferases have been grouped.into families based.on primary structure, one of which is fam- ily GT77 （***/GT77_***）.
