Agricultural development through settlement schemes on desert lands has always raised acute debates, especially over environmental issues due to cultivation based intensive additions of water and fertilizers. However, nutrient cycling approaches at the farm level are generally apparent N flows, i.e., purchased inputs sold products, without considering flows driven by mobile herds crossing arabl...

This study was conducted in a rice-based cropping scheme to investigate the impact of green manuring on soil health, considering physicochemical properties and sustainable crop production. A field experiment started 2 November 2015 completed 15 April 2018 under rice–berseem (Trifolium alexandrinum) system calcareous soil. Two patterns, rice–wheat–sesbania (rostrata), were compared with commonly...

Six year-round, all-forage, three-paddock systems for beef cow-calf production were used to produce five calf crops during a 6-yr period. Forages grazed by cows during spring, summer, and early fall consisted of one paddock of 1) tall fescue (Festuca arundinacea Schreb.)-ladino clover (Trifolium repens L.) or 2) Kentucky blue-grass (Poa pratensis L.)-white clover (Trifolium repens L.). Each of ...

This study investigated the ability of neonatal larvae of the root-feeding weevil, Sitona lepidus Gyllenhal, to locate white clover Trifolium repens L. (Fabaceae) roots growing in soil and to distinguish them from the roots of other species of clover and a co-occurring grass species. Choice experiments used a combination of invasive techniques and the novel technique of high resolution X-ray mi...
