Exceedance of the US Environmental Protection Agency national ambient air quality standard for PM10 (particulate matter ≤10 μm in aerodynamic diameter) within the Columbia Plateau region of the Pacific Northwest US is largely caused by wind erosion of agricultural lands managed in a winter wheat–summer fallow rotation. Land management practices, therefore, are sought that will reduce erosion an...

This work was carried out to determine the influence of the duration of fallow and of physico-chemical components of soils on the distribution of endomycorrhizal fungal spores and the mycorrhizal soil infectivity. The mycorrhization of indigenous plants from the fallows was examined and it was concluded that, except for Cassia obtusifolia, fungal colonization was poorly developed. No correlatio...

After comparing the persistence of four marking techniques, a mark–release–resight study was performed to characterize mid-season movement of the Colorado potato beetle [Leptinotarsa decemlineata (Say); Col., Chrysomelidae] simultaneously in a fallow and in a wheat field. Isolated patches of potatoes were installed in a random spatial arrangement on both fields similarly. Overwintered beetles w...

Some wild antelopes are fast sprinters and more resistant to fatigue than others. This study therefore investigated two wild antelope species to better understand their reported performance capability. Muscle samples collected post mortem from the vastus lateralis and longissimus lumborum of fallow deer (Dama dama) and springbok (Antidorcas marsupialis) were analysed for myosin heavy chain isof...

Th e incorporation of plant biomass (litter/prunned residues) into the soil constitutes an important pathway for nutrient cycling in ecosystems. Th e feasibility of meeting N needs of tomato (Lycopersicon esculentum Mill) with short-duration pigeon pea fallow was studied in the fi eld in Akure, a humid zone of Nigeria. Th e trials were set up on site where late season pigeon pea – maize intercr...

Abstract In the Mid-Atlantic United States, there is increasing interest in delaying cereal rye termination until after soybean planting (i.e., green). Improved understanding of seeding rate effects needed to balance weed and agronomic management goals. We investigated rates on control crop performance when green complementary experiments two regions. The Pennsylvania experiment was replicated ...

Shifting cultivation is the main land-use system transforming landscapes in riverine Amazonia. Increased concentration of the human population around villages and increasing market integration during the last decades may be causing agricultural intensification. Studies have shown that agricultural intensification, i.e. higher number of swidden-fallow cycles and shorter fallow periods, reduces c...

BACKGROUND Hunting constitutes an important industry in Europe. However, data on the prevalence of vector-borne bacteria in large game animal species are lacking from several countries. Blood or spleen samples (239 and 270, respectively) were taken from red, fallow and roe deer, as well as from water buffaloes, mouflons and wild boars in Hungary, followed by DNA extraction and molecular analyse...

This paper aimed to evaluate the productivity of corn crop for silage, beans and straw production in different rotation systems with spring/summer fall/winter green manures cultivated under agroecological management. The experiment was implemented a rural property managed an system since 2009, 2017/18 2018 crops. experimental design used randomized blocks, five repetitions. treatments consisted...
