AbstractAbstract
[en] Presented are investigation results of 31P-32P isotope exchange between phosphorus acid dichloroanhydrides and radioactive trichlorated and thiotrichlorated phosphorus and phosphorus oxychloride. The results confirm the presence of the exchan.oe in the mixture of trichlorated phosphorus with phosphorus acid dichloranhydrides. The 31P-32P isotope exchange being observed can be explained by the redistribution of substituents at phosphorus atom and is determined by the structure of phosphorus acid dichloroanhydrides

AbstractAbstract
[en] This study concerns the influence of certain experimental conditions and the effect of liming on the L value of an acid ferrallitic soil with a high fixing capacity. In the experiment conducted the lime increased the yield of ray-grass, and also its release of phosphorus, up to an amount of 200 ppm of P2O5 ; at higher doses the lime has a depressive effect. The L value, determined by using 32P without carrier, is very much on the high side; moreover the results are not very reproducible. It can be evaluated with sufficient accuracy when using carrier 31P. It is independent of the amount of carrier used, but the use of a minimum amount of carrier is essential in the case of soils depleted in labile P, such as the one studied here. Liming increases the initial L value of the soil. It also enables the soil to retain in a labile form a larger quantity of the phosphorus supplied as soluble phosphate. The use of an anionic resin provides clear confirmation of these results. (author)

Cette étude est relative à l'influence de certaines conditions expérimentales, d'une part, et du chaulage, d'autre part, sur la valeur L d'un sol ferrallitique acide, à fort pouvoir fixateur. Dans l'expérience réalisée, la chaux accroît le rendement du ray-grass, ainsi que son exportation en phosphore, jusqu'à une dose de 200 ppm de P2O5 ; pour des doses plus élevées, la chaux exerce un effet dépressif. La valeur L, déterminée en utilisant 32P sans entraîneur, est largement surestimée; d'autre part les résultats ne sont pas bien reproductibles. Elle peut être évaluée avec une précision satisfaisante en utilisant du 31P entraîneur. Elle reste indépendante de la quantité d'entraîneur utilisée; mais l'emploi d'une dose minimale d'entraîneur est indispensable dans le cas des sols pauvres en P labile, comme celui qui est étudié dans le mémoire. Le chaulage accroît la valeur L initiale du sol. Il permet d'autre part de maintenir sous forme labile une quantité plus importante du phosphore apporté sous forme d'un phosphate soluble. L'emploi d'une résine anionique confirme de façon très nette ces résultats. (author)Original Title

Use of Phosphorus Isotopes for Improving Phosphorus Management in Agricultural Systems2016
Use of Phosphorus Isotopes for Improving Phosphorus Management in Agricultural Systems2016
AbstractAbstract
[en] Estimations of P balances and fluxes are used in achieving the major objectives of improving P use efficiency in sustainable agricultural production and minimizing potential P losses to the environment. Farm P balances and fluxes when considered together with the results of soil test measurements would provide the first indication of where P inputs or outputs could be managed to achieve these objectives. The use of "3"2P and "3"3P isotopes in P flux and balance measurements offers considerable advantages over conventional techniques to identify P sources and quantify their impacts. (author)

AbstractAbstract
[en] Main trends in the development of methods for the synthesis of phosphorus-containing macrocyclic compounds in the past 15 years are considered. Emphasis is given to reactions producing macrocyclic structures with the participation of a phosphorus atom and other functional groups involved in organophosphorus molecules and to modifications of macrocycles by phosphorus compounds in different valence states. Possibilities of the practical application of phosphorus-containing macrocyclic compounds in difference areas of science and engineering are discussed. The bibliography includes 205 references.
