The Broadbalk Wheat Experiment at Rothamsted Research in the UK provides a unique opportunity to investigate the long-term impacts of environmental change and agronomic practices on plants and soils. We examined the influence of manure and mineral fertiliser applications on temporal trends in the stable N ((15)N) and C ((13)C) isotopes of wheat collected(More)
Many semi-arid areas worldwide are becoming degraded, in the form of C(4) grasslands being replaced by C(3) shrublands, which causes an increase in surface runoff and erosion, and altered nutrient cycling, which may affect global biogeochemical cycling. The prevention or control of vegetation transitions is hindered by a lack of understanding of their(More)
OBJECTIVE To compare the use of intermittent urethral catheterization with indwelling suprapubic catheterization in women undergoing surgery for urodynamic stress incontinence or uterovaginal prolapse. DESIGN Randomized controlled trial. SETTING Tertiary referral urogynaecology unit. POPULATION Women undergoing surgery for pelvic organ prolapse and/or(More)
Large old trees are the dominant primary producers of native pine forest, but their influence on spatial patterns of soil properties and potential feedback to tree regeneration in their neighbourhood is poorly understood. We measured stable isotopes of carbon (delta(13)C) and nitrogen (delta(15)N) in soil and litter taken from three zones of influence(More)
INTRODUCTION AND HYPOTHESIS Overactive bladder syndrome with urinary incontinence has a number of treatment options. The National Institute for Health and Care Excellence (NICE) in the UK, the American Urological Association (AUA) and the European Association of Urology (EAU) recommend intradetrusor botulinum neurotoxin A (onabotulinumA) injections in women(More)
A study was undertaken on drained and undrained 1 ha grassland lysimeters to assess the effectiveness of multiple novel tracing techniques in understanding how agricultural slurry waste moves from land to water. Artificial fluorescent particles designed to mimic the size and density of organic slurry particles were found to move off the grassland via(More)
Little is known about the interaction of the soil's physicochemical environment and livestock slurry throughout the soil profile. In this study, five soil layers (2-6, 6-10, 10-14, 14-18, 18-22 cm) amended with a<45 microm slurry fraction (FS) or water (control) were incubated for 58 d at 20 degrees C to determine the effect of the slurry position in the(More)
