Phosphorus is a macronutrient that plays a number of important roles in plants. It is a component of nucleic acids, so it plays a vital role in plant reproduction, of which grain production is an important result. It is also critical in biological energy transfer processes that are vital for life and growth. Adequate phosphorus results in higher grain production, improved crop quality, greater ...

Non-collagenous phosphoproteins, almost all of which can be extracted in EDTA at neutral pH in the presence of proteinase inhibitors, are identified in the matrix of chicken bone, and are therefore not covalently bound to collagen. Similarly, all the peptides containing y-carboxyglutamic acid are present in the EDTA extract and none in the insoluble residue, confirming that none is covalently l...

Manure was collected from growing pigs (22–48 kg) fed one of 11 diets varying in total and available phosphorus content. Reduced phosphorus diets were amended with feed additives intended to improve availability of phytate phosphorus. Diets were replicated over three feeding periods resulting in 33 manure samples. Collected manure samples were diluted (final solids content approximated 2.4% tot...

This experiment was conducted to determine the effects of nitrogen and phosphorus fertilizers on nutritive value of safflower forage and silage by in situ and in vitro methods. The safflower forage was harvested at flowering stage, chopped to 3-5 cm particles and then ensiled in the laboratory silos for 60 days. The experimental treatments included: 1. Unfertilized forage (control), 2. Phosphor...

The distribution of phosphorus compounds in various leaf components has been examined in some detail, particularly for tobacco, where interest has centered in part on the study of nucleic acids, especially in relation to virus infection (2-7). The method adopted for determining phosphorus distribution in the present study was based on the procedure of Ogur and Rosen (8), and on the results of o...

[1] Dry deposition rates and associated inputs of soluble inorganic nitrogen (N) phosphorus (P) and iron (Fe) were calculated for the north coast of the Gulf of Aqaba in Eilat, Israel, between August 2003 and September 2005. The main inorganic N compounds in the water soluble fraction of aerosol particles were nitrate (60%) and ammonium (38%), with mean concentrations of 35 and 22 nmol m 3 of a...

Soil incubation and pot experiments were conducted to follow the sorption processes of added phosphorus (P) fertiliser using radioisotope tracer technique. Increasing doses P (40, 80, 160, 320 mg P/kg soil) Chernozem Arenosol incubated for 1, 3, 13 weeks. After incubation, perennial ryegrass (Lolium perenne L.) was sown in one group pots, experiment had been continuing another 9 The yield, gras...

in order to investigate the role of bacillus cogulans on yield of two forage corn cultivars, an experiment carried out at agricultural research center of tehran province during 2009-2010. the experiment design consisted of three randomized complete blocks in a factorial arrangement. investigated treatments consisted of the kind of phosphorus and cultivar. the phosphorus factor included of the a...
