Soil bacteria regulate wetland biogeochemical processes, yet little is known about controls over their distribution and abundance. Bacteria in North Carolina swamps and bogs differ greatly from Florida Everglades fens, where communities studied were unexpectedly similar along a nutrient enrichment gradient. Bacterial composition and diversity corresponded strongly with soil pH, land use, and re...

Slurry injection below maize seeds is a rather new application technique developed to improve the nitrogen use efficiency of liquid organic manure. To enable the characterization of the spatial and temporal soil mineral nitrogen (SMN) dynamics after slurry injection the present study aims to develop an appropriate soil sampling strategy. Three consecutive experiments were conducted. The first t...

The term 'optimum nutrition' has evolved from a perceived need to base recommendations for nutrient intakes firmly in the context of function. It follows that 'optimum nutritional status' for individual nutrients should be defined in terms of biochemical or physiological markers having some functional value but also showing an appropriate relationship to nutrient intake. The present short revie...

Kalanchoë blossfeldiana Poelln. cv Hikan plants were grown hydroponically with nutrient solution containing 5 millimolar NO(3) (-) (or NH(4) (+)) for 1 to 2 months and then transferred to nutrient solution containing no nitrogen. CO(2) uptake at night, nocturnal increase in titratable acidity, and activity of phosphoenolpyruvate carboxylase increased after the transfer. Thus, transfer to nitrog...

Received Oct 10, 2015 Revised Dec 20, 2015 Accepted Feb 16, 2016 The nutrient in the meal is very important, especially for the children at the toddler’s age. The aim of this research was to know the correlation between the food schemes with the children nutrient status at the toddler’s age (1-3 years). The research design was cross sectional. The population for this research was all of the mot...

We used Vollenweider mass balance model that can predict maximum allowable nutrient loading rates or load limits (LM) for prediction of trophic status in Lake Baiyangdian’s fresh waters. The average annual hydraulic inflow rate (Qi) and nutrient input concentration (CPi) explained most of the variation in LM for guiding the lake management. We found such a single model for total phosphorus (TP)...

We investigated the nitrogen and phosphate nutrient status in the habitats of Alternanthera philoxeroides and its co-occurring algal growth in a field survey. We also determined the algicidal activity of A. philoxeroides extracts from a diversity of habitats in Chaohu Lake, China, in the laboratory. We then tested the correlation between the nutrient status and the algicidal activity of A. phil...

OBJECTIVE To describe the reported energy and nutrient intake and adequacies in Mexican women. MATERIAL AND METHODS A 24-hour dietary recall was used to obtain nutrient intake in a representative sub-sample of 2,630 women from 12 to 49 years of age from the National Nutrition Survey 1999. Nutrient adequacies were estimated using the Dietary Reference Intakes and stratified according to region...

Abstract—Eutrophication of surface water is one of the most widespread environmental problems at present. Large number of pilgrims and tourists visit sacred artificial tank known as “Brahma Sarover” located at Kurukshetra, India to take holy dip and perform religious ceremonies. The sources of pollutants include impurities in feed water, mass bathing, religious offerings and windblown particula...
