Abstract Due to the impacts of climate change and reduction in flow Mekong River, saline intrusion into inland has been an emergent pressing issue. The purpose this study is analyze effects various conditions (0–25‰) on changes some soil properties under laboratory conditions. Ten topsoil samples were collected from a depth 0–20 cm dry seasons rice–corn rotation fields with low salinity, Thanh ...

BACKGROUND Dietary phosphate restriction prevents renal function deterioration in animal models. This study examined whether sevelamer hydrochloride (Renagel(R); 'sevelamer' hereafter), a non-calcaemic phosphate binder could slow deterioration of renal function in rats with progressive renal insufficiency. METHODS Wistar Kyoto male rats were singly injected with normal rabbit serum or rabbit ...

BACKGROUND Secondary hyperparathyroidism characterized by hyperplasia of the parathyroid gland (PTG) is a consequence of chronic renal insufficiency (CRI). Dietary phosphate restriction and sevelamer hydrochloride, a calcium-free phosphate binder, suppress parathyroid hormone (PTH) secretion and PTG hyperplasia in experimental animals with CRI, independently of serum calcium and 1,25(OH)(2)D(3)...

an experiment was conducted to evaluate the effects of 1α-oh-d3 either with or withoutcholecalciferol, microbial phytase as well as different levels of dietary calcium, and phosphorus onbroiler chickens, performance. a number of 576 male broiler chickens (ross 308) were made use of ina completely randomized design of a factorial arrangement (3×2×2×3), comprised of 36 treatments, 4replicates of ...

diversification of phosphorus sources can bring substantial synergy effects within all thesustainable development domains: environmental, economic and social, and such an opportunity should not beoverlooked. urban sinks accumulate phosphorus and other elements and may serve as sources of secondaryraw materials. this paper evaluates phosphorus sources based on their total material requirement (t...

[P la te 6] A technique has been developed for the determination of the absolute surface energies of iron and iron alloys at temperatures of up to the melting point. The technique is based upon the measurement of the contractile forces in thin foils. All measurements are made in situ and chemical equilibrium is maintained throughout the experiment. The results show that phosphorus in dilute sol...

Wheat (Triticum aestivum L.) was grown in earthen pots containing soil of Balkasar Soil Series (Sandy Loam) in green house at the Department of Soil Science and SWC, Pir Mehr Ali Shah Arid Agriculture University, Rawalpindi during Rabi season, 2007. The Crop was treated with two levels of Phosphorus (40 and 80 kg P ha-1 ) in the form of SSP, TSP, NP and DAP. A basal doze of 100 kg N and 60 kg K...

Ruminal bacteria and protozoa provide excellent organic phosphorus (P) sources for the host animal. This experiment was conducted to compare the bioavailability of bacterial and protozoal P in comparison with that of dicalcium phosphate (DCP) as a reference phosphorus source. Bacteria and protozoa were isolated from the rumen contents of dairy cows and the chick-model was used to determine the ...

Nutrient availability regulates the responses of high-latitude ecosystems to climate change but nitrogen, phosphorus and sulfur biogeochemistry, especially, phosphorus and sulfur cycles, are poorly understood in Alpine tundra ecosystem. This study examines the cycling of nutrients in a 302-year-old Alpine tundra ecosystem in which litter has accumulated through compartment methods. Samples of t...

In sorghum and mungbean – lentil cropping system, field experiments were conducted for three successive years to assess the effect of mung bean residue incorporation on sorghum and succeeding lentil productivity along with different doses of phosphorus (P; 0, 30, 60 kg ha−1) applied to these crops. The level of soil fertility was also tested with or without incorporation of mung bean residue. T...
