To survey the effects of chemical and biological phosphorus on the yield and essential oil of Satureja hortensis L. as an important medicinal plant, factorial experiment was conducted based on randomized complete block design with three replicates at Research Station of Faculty of Agriculture, Urmia University in 2011. The treatments were chemical phosphorus fertilizer with four levels (0, 50, ...

BACKGROUND Serum phosphorus concentrations are associated with an increased risk of cardiovascular disease (CVD) and mortality in patients with renal insufficiency. This association has also been reported in Western individuals without chronic kidney disease (CKD). OBJECTIVE It is unclear, however, whether this correlation occurs in Korean individuals without CKD, who usually ingest less phos...

abstract the increasing of yield per unit area is usually achievable by improving the soil fertility level through using (chemical) fertilizers. the purpose of the present research was to evaluate the 6 extraction methods including olsen, morgan, ammonium bicarbonate-dtpa, colwel, bray and mehlich 3 in order to specify a suitable extractant(s) for estimating available phosphorus through using 2...

walnut tree is grown for multiple purposes. indeed, it is economically important and increasing its yield and improving its quality in order to compete in the international markets is one of great importance. to this end, one significant management practice is proper use of suitable fertilizers. zinc and phosphorus are two important elements in the nutrition of walnut. in this study, experiment...

were analysed for wet and dry weight, total lipid, total, free and esterified cholesterol, total carboxyl ester, lipid phosphorus and triglyceride. The translocated testes decreased in wet and dry weight (P<0\m=.\001) and total lipid content (P< 0\m=.\001)6 days after surgery. Lipid concentration increased (P<0\m=.\01)in translocated testes, as did concentrations of total cholesterol (P<0\m=.\0...

This study was designed to advance understanding of phosphorus regulation of Microcystis aeruginosa growth, phosphorus uptake and storage in changing phosphorus (P) conditions as would occur in lakes. We hypothesized that Microcystis growth and nutrient uptake would fit classic models by Monod, Droop, and Michaelis-Menten in these changing conditions. Microcystis grown in luxury nutrient concen...
