Leaf and soil nitrogen and phosphorus availability in a neotropical rain forest of nutrient-rich soil.
The nitrogen and phosphorus supply in a lowland rain forest with a nutrient-rich soil was investigated by means of the leaf N/P quotient. It was hypothesised a high N and P supply to the forest ecosystem with a N and P rich soil. Total N and extractable P were determined in the surface (10 cm) soil of three plots of the forest. Total N was analysed by the Kjeldahl method, and P was extracted wi...
متن کاملNitrogen and phosphorus resorption in a neotropical rain forest of a nutrient-rich soil.
In tropical forests with nutrient-rich soil tree's nutrient resorption from senesced leaves has not always been observed to be low. Perhaps this lack of consistence is partly owing to the nutrient resorption methods used. The aim of the study was to analyse N and P resorption proficiency from tropical rain forest trees in a nutrient-rich soil. It was hypothesised that trees would exhibit low nu...
متن کاملThe effect of phosphorus on nitrogen retention in lakes
A hypothesis has been presented that nitrogen retention in lakes has become less efficient at the same time as phosphorus concentrations have decreased due to high phosphorus reduction in wastewater treatment. This might have led to higher loading of nitrogen into the Baltic Sea where nitrogen is considered to be the minimum nutrient. The hypothesis was tested using the mass balance modelling a...

15 صفحه اولNutrient, chlorophyll, and water clarity relationships in Florida’s nearshore coastal waters with comparisons to freshwater lakes
Models relating chlorophyll to nutrients and Secchi depth to chlorophyll using data from nearshore coastal waters of Florida were successfully developed. The models suggest that phosphorus is the primary limiting factor for phytoplankton in the nearshore coastal waters of Florida and that total phosphorus concentration accounts for 81% of the variance in chlorophyll concentration. The models al...
