phosphorus acquisitionphytateWe evaluated the ability of Brassica napus L. (oilseed rape), Helianthus annus L. (sunflower), and Glycine max L. (soybean) plants grown inoculated with or without bacteria to utilize organic P sources. Plants were supplied with inorganic (dibasic sodium phosphate) ...
Doses above the recommended (400 kg ha-1 of P2O5 according to the literature for soils with low phosphorus content: 6 mg dm-3), regardless of the source, resulted in an increase in the values of the characteristics evaluated, but, with a decrease in the increases as high was the dose,...
Similarly effort should be directed to estimating the rates of transformations, not simply reporting on the concentrations. And finally, further work is needed in elucidating other roles of organic P in the environment other than simply a source of P to aquatic organisms. 展开 关键词:...
Today on many sites organic farming might neglect phosphorus (P) fertilization due to soil reserves build up by P fertilization of former farming systems. Additionally organic farming has restricted itself to the use of non-solubilised rock phosphate as mineral fertilizer source that only has ...
One of the most intriguing, and persistent, questions concerning the marine sedimentary organic phosphorus reservoir is the following. Given that the ultimate source of organic phosphorus to marine sediments is the phosphorus biochemicals contained within plant and animal tissues, and that these biochemica...
Despite that organic phosphorus (Po) is a source of bioavailable P during the early stage of soil development, it remains unclear whether P availability or organic carbon (C) mineralization is the main regulator of Po mineralization. In this study, the P availability (labile inorganic P, Pi) ...
Of-note, aromatic groups were directly bonded to the phosphorus center in quaternary phosphonium derivatives to form a typical molecular rotor; therefore, they may adopt various conformations in rigid surroundings since the rotating aromatic groups will be fixed at different angles, which are closely ...
Effects of grain legumes on succeeding non-legumes in a rotation and their response to source of phosphorus To determine the potential of barley, lentils, lupins and peas and the soil incorporation of their different plant parts to maintain soil fertility, soil c... V Ganeshan - 《Lincoln Uni...
Pentavalent phosphorus forms two main series of organic compounds with active hydrogen. These are the organicphosphonatesR-P(=O)(OH)2andorganic phosphatesR-O-P(=O)(OH)2where R can be alkyl or aryl. Phosphonic andphosphoric acidsare relatively strong acids (for methyl phosphate, pKa=1.54). ...
