Canola (Brassica napus L.) is a nitrogen (N)-demanding crop, so tissue N analysis should be related to soil supply. We evaluated canola uptake in relation pools plots receiving 0, 50, 100 and 150 kg ha-1 from urea at three sites eastern Canada 2012. Soil varied significantly the rosette, flowering, pod filling maturity stages, but responded less predictably urea. was inconsistently input. This ...
Aim Tropical ecosystems have grown increasingly prone to fire over the last century. However, no consensus has yet emerged regarding effects of disturbances on tropical biogeochemical cycles. Location Tropics. Time period 1960–2018. Major taxa studied ecosystems: Above- and below-ground carbon (C) nitrogen (N) dynamics. Methods We analysed impacts C N dynamics in through a meta-analysis 1,420 o...
Extreme floods, including those expected to become more frequent in a warming world, may impact nutrient metabolism streams. However, flood impacts on spatial and temporal variability of dynamics large rivers (e.g., fourth order higher) have been understudied. In 2016, Hurricane Matthew provided unique opportunity evaluate nitrate retention processing the Lumbee River, blackwater stream southea...
Context The Australian Alps are recognised by UNESCO as a globally significant mountain range. Soils underpin all of these ecosystem services. However, sparse data exists on alpine soils. Aims and methods We explored nitrogen dynamics soils from four high sites, using combination new established field laboratory techniques. Key results Organic inorganic N were the same order magnitude, with aro...
Background: Composting as a waste management technology is becoming more widespread. The purpose of this study was to assess the feasibility and to find the most effective composting process for the ratio of green waste, digested and dewatered sludge from Chonibieh wastewater treatment plant in the west region of Ahvaz. Methods: The composting time was 23 days and the evaluated parameters in th...
