Recently developed isotopic methods enable comparison of oxygen isotopes in soluble dissolved inorganic phosphate (DIP), potentially allowing sources of phosphates in aquatic systems to be identified. For the phosphate isotope method, phosphate is chelated into a magnesium hydroxide precipitate, precipitated...
Plants require inorganic nutrients in addition to carbon dioxide and water for growth and production. Nutrients are present in soil, but get depleted unle... S Kannan 被引量: 45发表: 2010年 Synthesis and characterization of ammonium phosphates fertilizers with boron The concentration of boron, an...
In most applications, phosphorus-containing fine chemicals are in the naturally occurring and most stable oxidation state +V of the element; however, syntheses to these compounds from primary PV sources rely on an energy-consuming and wasteful redox detour via elemental white phosphorus (P4) and ...
Especially if you live in a rural area where there are lots of farms. When it rains, fertilizer can wash into the groundwater and contaminate it with phosphates and nitrates, which can lead to problems in your aquarium. So while you may have to harden or soften your well water, at least...
Furthermore, the use of bonemeal additions has been evaluated as a remediation treatment for metal-contaminated soil, with the ability to immobilize pollutant metals and reduce their bioavailability through the formation of metal phosphates. In addition, the use of zinc-coated urea fertilizers has ...
A REVIEW OF TRACER STUDIES IN SASKATCHEWAN ON THE UTILIZATION OF PHOSPHATES BY GRAIN CROPS* The use of P 32 as a tracer has been particularly valuable in studying the uptake of phosphorus from fertilizer and soil. It is a technique which may be used to differentiate between the availability ...
As a result of pumping and subsequent declines in water levels, chloride concentrations have increased in water from wells in the Eastern San Joaquin Ground-Water Subbasin, about 80 miles east of San Francisco (Montgomery Watson, Inc., 2000). Water from a number of public-supply, agricultural...
The examined parameters were the inlet pH of treated water, the initial arsenic concentration, empty bed contact time (EBCT), arsenic speciation and the concentration of iron solution, used for the coating process. The effect of competitive anions in the aqueous solution, such as phosphates as ...
ONGC Announces Second Interim Dividend Of Rs 5 Per Share The company has set Feb. 7, 2025, as the record date to determine the shareholders eligible for the dividend. 8.5 hours ago — Bloomberg Quint Economic Survey notes significant progress in sanitation, water supply It says tap water cov...
The aim of the present study was to evaluate the productive performance of commercial laying hens supplemented with four commercial sources of inorganic phosphates for four weeks. In total, 960 Hy-Line Brown hens of 56 weeks of age were distributed in 4 treatments with 6 repetitions each and 40...
