摘要:... Total phosphorous (TP), organic phosphorous (OP), inorganic phosphorous (IP) and available phosphorous (AP) were measured to study their horizontal and vertical distribution patterns in the land/inland water ecotone, as well as their important influencing factors such as ...

摘要:... IBE profiles were studied to evaluate the total contents of P, its primary chemical forms and the P transformation phases in areas with IBE soils of variable texture and in adjacent reference soils. The soil texture strongly influenced soil fertility, changing in terms of t...

摘要:... Phosphorous was measured in three forms: orthophosphates, hydrolysable phosphate (polyphosphates), and total phosphorous. The difference [total phosphorous] - {[hydrolysable phosphorous] + [orthophosphates]} gives a good idea of the organic origin phosphorous content.The qual...

摘要:Abstract(#br)By means of SEDEX, ASPILA and XRF, depth-dependent changes of different phosphorus forms in sediment cores from specific areas of the offshore Changjiang Estuary (Yangtze Estuary) in 1998 were analyzed. Results show that contents of total phosphorus (TP), organic...

摘要:... During the experiment, dredging the upper 30 cm layer could efficiently reduce the interstitial PO 3 4 -P concentration and different P forms in the sediment. The P fluxes of the undredged and dredged cores ranged from −5.1 to 3047.6 and −60.7 to 14.4 μg m −2 d −1 ,...
