A glasshouse study was conducted to investigate the effect of supplying phytate and FePO4 and interspecific root interactions on the uptake of Ca, Mg, Fe, Mn and Zn by plants in a mixed culture of wheat (Triticum aestivum L.) and chickpea (Cicer arietinum L.). The pots were separated into two compartments by (i) a solid root barrier to eliminate root(More)
In this study, we investigated crop yield and various chemical and microbiological properties in rhizosphere of wheat, maize, and faba bean grown in the field solely and intercropped (wheat/faba bean, wheat/maize, and maize/faba bean) in the second and third year after establishment of the cropping systems. In both years, intercropping increased crop yield,(More)
A 2-year study was conducted to investigate the potential of no-till cropping systems to reduce N2O and NO emissions under different N application rates in an irrigated corn field in northeastern Colorado. Flux measurements were begun in the spring of 2003, using vented (N2O) and dynamic (NO) chambers, one to three times per week, year round, within plots(More)
Biogeosciences Discussions This discussion paper is/has been under review for the journal Biogeosciences (BG). Please refer to the corresponding final paper in BG if available. Abstract Chinese grasslands are extensive natural ecosystems that comprise 40 % of the total land area of the country and are sensitive to N deposition. A field experiment with six N(More)
Zinc (Zn) fertilization is an effective agronomic tool for Zn biofortification of wheat for overcoming human Zn deficiency. But it still needs to be evaluated across locations with different management practices and wheat cultivars, since grain Zn concentrations may be significantly affected by locations, cultivars and management. Field experiments were(More)
Increasing zinc (Zn) concentration of rice seed has potential benefits for human nutrition and health. Enhanced levels of Zn in grain also contributes greatly to crop production through better germination and seedling vigor of rice plants grown on soils with limited Zn supply. This study evaluated the effect of soil and/or foliar Zn fertilizer application(More)
Cereal/cereal and cereal/legume intercropping systems are popular in the north, northwest, and southwest of China and often result in yield increases compared to monocropping. Rhizosphere interactions may play a significant role in the yield increases, particularly with respect to nutrient availability. The aim of this study was to investigate the effects(More)
—A novel hybrid design of Bluetooth and UWB antenna with dual band-notched functions is proposed. The proposed antenna structure consists of a microstrip-fed main patch and electromagnetically coupled parasitic patch with arc-shaped strips, achieving Bluetooth and UWB performance. Additionally, the split ring resonator (SRR) slot etched on the main patch(More)
—In this article, a printed ultra-wideband (UWB) monopole antenna with dual band-notched characteristics of size 26 mm × 35 mm is presented. The prototype consists of pincers-shaped radiation element and corner rounded ground plane. By inserting a pair of flexuous slots on the radiation element and a C-shaped slot on the ground plane, the 3.5/5.5 GHz dual(More)
