In dryland cropping systems, optimal yields require that nutrient supply matches the soil’s yield potential supported by available moisture. Conservation tillage systems that leave at least 30 percent of the soil surface covered by residue dramatically increase moisture retained in the soil compared to crop-fallow systems. This enables producers to plant two, three, or four consecutive crops, o...

During a 6-year study of 1-, 2-, and 3-year crop rotations, population densities of Pratylenchus brachyurus, Trichodorus christiei, and Meloidogyne incognita were significantly affected by the choice of crops but not by length of crop rotation. The density of P. brachyurus and T. christiei increased rapidly on milo (Sorghum vulgate). In addition, populations of P. brachyurus increased significa...

While social and behavioural contexts are known to affect the acoustic structure of vocal signals in several mammal species, few studies have investigated context-related acoustic variation during inter-sexual advertisement and/or intra-sexual competition. Here we recorded male fallow deer groans during the breeding season and investigated how key acoustic parameters (fundamental frequency and ...

To provide a new way to increase water storage and retention of dryland wheat, a field study was conducted at Wenxi experimental site of Shanxi Agricultural University. The effect of subsoiling in fallow period on soil water storage, accumulation of proline, and formation of grain protein after anthesis were determined. Our results showed that subsoiling in fallow period could increase water st...

Relationships between soil characteristics, various forms of soil organic matter, microbial biomass and the structure of phytoparasitic nematode populations were investigated in six fallow fields aged from 1 to 26 years in the West African Savanna (WAS) belt in southern Senegal. Soil sampling was performed along two transects in each field. Herbaceous biomass and soil physical, chemical and bio...

Carbon dioxide is an important greenhouse gas and a major agent of climate change. This study quantified carbon (C) emissions from energy consumption and C storage and uptake by greenspace for three cities in middle Korea: Chuncheon, Kangleung, and Seoul. Carbon emissions were estimated using C emission coefficients for fossil fuels consumed. Carbon storage and uptake by woody plants were compu...

For many of Utah’s rural communities, the problem of either growth or decline has been compounded by dependency on public lands and the changing perceptions by the general public of how these lands should be used. Utah communities whose economies have revolved around farming, ranching, and extraction of natural resources have depended upon access to and use of public lands, but use of these lan...

loaded and a portion of the nitrate is absorbed by the blood stream as nitrate and nitrite. Some of the nitrate Nitrate contained in forage may pose performance and health risks that is absorbed recycles back to the rumen through to ruminants. With timely and accurate assessment of forage nitrate levels, steps to reduce the risks of excessive nitrate intake by livestock saliva thereby adding ag...

The 53.1 acre Stone Road Retail property, located on the northeast corner of Edinburgh & Stone Road in Guelph, is comprised of the following: 9.9 acres Edinburgh Market Place constructed in 1996; 6.4 acres zoned service/commercial, 9 acres high density residential and 27.7 acres institutional/research park. The 9 acre property, leased to Richmond Properties Ltd is comprised of private sector re...

Field observations indicated that Zn deficiency of beans (Plasscoins melons L.) was sometimes more severe than expected when grown on Mowed soil that was low to marginal in available Zn. The objectives of this study were to determine the effects of fallow, suprbeets (Beta Moods L.), and corn (Zea mays L.) on Zri availability to subsequent crops grown on a Portneuf silt loam (Durixerollic Calcio...
