Phosphorus Measurements in Aqueous Media Using Inorganic Phosphorus Sources as Compared to Organic Sources and Resulting Complications
<p>The phosphorus moiety that exists in both inorganic and organic molecules has significant importance. Phosphorus serves as nutrient, a plant building block, a control agent for pests (both plant and insect), and can be an inadvertent cross contaminant in herbicide production, and is often seen …

Interactions Between Land Use and Local Lithology on Phosphorus Distribution in Northrup Creek Sediments, Monroe County, New York
Phosphorus, a key nutrient in many aquatic systems that limits the growth of algae, plays a key role in the occurrence of eutrophication and toxic algal blooms. Past research has shown that land use and lithology are major contributors of phosphorus in a creek. High levels of organic phosphorus …

Phosphorus biogeochemistry and models in estuaries: case study of the Southampton Water system
… and the major features of nutrients (nitrogen, phosphorus and silicon) and suspended particulate matter (SPM) thus obtained. Additionally phosphorus in pore waters, and the solid phase in sediments were measured. The forms of phosphorus in the solid phase of sediment (deposited and suspended) …

Inheritance of Soluble Oligosaccharides in Soybean Seeds
… a negative relationship was observed between inorganic phosphorus and stachyose content of soybean seeds but a relationship was not observed between stachyose and phytate phosphorus or between inorganic phosphorus and phytate phosphorus.

Heterologous Expression of Arabidopsis Thaliana Purple Acid Phosphatase Gene (Atpap15) in Crops for Phytoremediation of Sites Contaminated with Excess Phosphorus
… pH with maximal activity at pH 4.5. AtPAP15 is a phosphorus starvation inducible (PSI) gene that is expressed highly during phosphorus deficient conditions. In the current study, AtPAP15 was overexpressed in Nicotiana tabaccum under cauliflower mosaic virus (CaMV35S) constitutive promoter. After …

Digestibility and palatability of animal, vegetable and animal-vegetable blended fats by the equine
… serum levels of total fatty acids, calcium, inorganic phosphorus, magnesium and glucose were not affected by the addition of the fats. However, serum cholesterol levels were increased (P <.05) by addition of fat. In Digestion Experiment II, feeding four fats (corn oil, peanut oil, inedible …

Nutrient Transport in the Lake Poinsett System
… Lake Poinsett transported 1.66 x 104 kg (PO4) phosphorus, 1.28 x 104 kg nitrate nitrogen, and 3.90 x 104 kg organic carbon. The Big Sioux River-Dry Lake system contributed 63% of the phosphorus, 45% of the nitrate nitrogen, and 43% of the organic carbon load. The remaining portion entered Lake …

Effect of dietary calcium and phosphorus levels on magnesium utilization in sheep
… the effects of feeding two levels of calcium and phosphorus alone and in combination, on magnesium utilization in ruminants. Twelve wether lambs were used in two metabolism trials. The two levels of calcium were 0.4 and 1.4% and the two levels of phosphorus were 0.3 and 1.3%. Apparent magnesium …

Microbiological influences on phosphorus release from aerobic lake sediments
… Classical theories concerning the regulation of phosphorus release from sediments by oxidation-reduction potential neglect the potential of microorganisms to transfer large amounts of phosphorus out of sediments. Aerobic surface sediments collected from the eutrophic Occoquan Reservoir, Virginia, …

Desarrollo y aplicaciones de un simulador de mezcla dinámica para el estudio de la reactividad química en estuarios
… to show its possibilities. So, the behaviour of inorganic carbon along different salinity gradients has been studied (quantifying CO2 fluxes water-atmosphere). Tidal variations at CO2 fluxes also were registered. By other hand, nutrient reactivity has been characterised, putting special attention …

Characterization of Soybean Germplasm with Modified Phosphorus and Sugar Composition
… [Glycine max (L.) Merr.] cultivars with modified phosphorus (P) composition has nutritional and environmental benefits, but poor seed germination and emergence presents challenges for commercial production. Different genetic mutations in two sources of germplasm, CX1834 and V99-5089, decrease the …
