Influence of phosphorus application and arbuscular mycorrhizal inoculation on growth, foliar nitrogen mobilization, and phosphorus partitioning in cowpea plants.

The present study was undertaken to evaluate the effects of phosphorus (P) application and arbuscular mycorrhizal (AM) fungi (Funneliformis mosseae) on growth, foliar nitrogen mobilization, and phosphorus partitioning in cowpea (Vigna unguiculata cv. Vita-5) plants. The experiment was conducted in a greenhouse in pots containing a mixture of vermiculite and sterilized quartz sand.

Recovery of biosolids from constructed wetlands used for faecal sludge dewatering in tropical regions.

Biosolids recovered from yard-scale vertical-flow constructed wetlands used for faecal sludge dewatering in Cameroon, were analyzed to assess their degree of maturity, nutrient and heavy metals contents, as well as their hygienic quality. Six beds were loaded weekly at nominal loading rate of 100, 200, and 300 kg TS/m2/year. The quality of the biosolids accumulated in the beds was monitored during 6 additional months of resting period prior to final harvest.
