Effect of influent nutrient ratios and hydraulic retention time (HRT) on simultaneous phosphorus and nitrogen removal in a two-sludge sequencing batch reactor process [PDF]
, 2009 A laboratory-scale anaerobic–anoxic/nitrification sequencing batch reactor (A2N- SBR) fed with domestic wastewater was operated to examine the effect of varying ratios of influent COD/P, COD/TN and TN/P on the nutrient removal.

Brachiaria as a Cover Crop to Improve Phosphorus Use Efficiency in a No-till Oxisol
Revista Brasileira de Ciência do SoloOxidic soils are phosphorus drains in soil; hence, P availability is a limiting factor in tropical, weathered Oxidic soils. It has been shown that some brachiarias grown as cover crops may increase soil available P to subsequent crops.

Phosphorus Balance and Soil Phosphorus Status in Paddy Rice Fields with Various Fertilizer Practices
Plant Production Science, 2013 Excess phosphorus (P) has accumulated in Japanese paddy soils, due to fertilizer P inputs over crop requirement for several decades, and improvement of the excess of P is necessary in view of environmental conservation.

Imaging atomic vacancies in commercially available black phosphorus
, 2017 Black phosphorus (BP) is receiving significant attention because of its direct 0.4-1.5 eV layer-dependent band gap and high mobility. Because BP devices rely on exfoliation from bulk crystals, there is a need to understand native impurities and defects ...

Human alteration of the global nitrogen and phosphorus soil balances for the period 1970-2050 [PDF]
, 2009 The Millennium Ecosystem Assessment scenarios for 2000 to 2050 describe contrasting future developments in agricultural land use under changing climate. Differences are related to the total crop and livestock production and the efficiency of nutrient use

Optimizing Phosphorus Application for Winter Wheat Production in the Coastal Saline Area
Agronomy, 2022 Phosphorous (P) fixation in saline soils is a concern worldwide. To investigate optimization strategies for P fertilizer application that improve P use efficiency (PUE) and crop yield in saline soil, in terms of P sources and rates, we conducted a two ...
