Tillage and phosphorus management effects on enzyme-labile bioactive phosphorus availability in Cerrado Oxisols
(Elsevier B.V., 2010-05-15)
Phosphorus (P) is an essential element in crop nutrition, which can be growth limiting or an environmental contaminant, if present in excess. Tillage practices have a direct effect on the behavior and availability of soil ...
Assessing Organic Phosphorus Contributions for Predicting Soybean Response to Fertilization
(Soil Science Society of America, 2016-08)
The use of organic P fraction in soil test P for soybean [Glycine max (L.) Merr.] under no-till could improve the accuracy to predict crops response to P fertilization. The research objectives were to assess the contribution ...
Phosphorus in Antarctic surface marine sediments - chemical speciation in Admiralty Bay
(Oxford, 2013-06-11)
This study describes the relation of the phosphorus chemical speciation in surface sediments with input processes in Admiralty Bay, King George Island, Antarctica. The sediments were analysed with a sequential extraction ...
Assessing soil P fractions changes with long‐term phosphorus fertilization related to crop yield of soybean and maize
(Wiley, 2020-02)
Long-term P fertilization increases soil phosphorus (P) labile fractions, which can be associated with crop P uptake and grain yield and are useful to improve fertilizer recommendations. Research aims were to evaluate in ...
Phosphorus fractions and sorption dynamics in the sediments of two Ca-SO4 water reservoirs in the central Argentine Andes
(International Research and Training Centre on Erosion and Sedimentation, 2017-09-16)
Phosphorus (P) fractionation and sorption behavior were studied in the sediments of two calcium-sulfate (Ca-SO4: Ca2+170 mg L-1; SO42- 400 mg L-1) water reservoirs in the southern central Argentine Andes - El Carrizal ...
