Developed and Evaluation of Slow Release Phosphorus Fertilizer Using Mono-ammonium Phosphate and Di-ammonium Phosphate

Molecular Interaction Studies of Ammonium Dihydrogen Phosphate in the Aqueous Solutions of Mono, Di and Triprotic Acids – An Ultrasonic Study

Aqueous solutions of mono, di, and triprotic acids were prepared with different molar percentages (say 10%, 20% and 30%). ammonium dihydrogen phosphate is gradually introduced in the aqueous solutions at different concentrations varied from 0.1M to 0.6M at 303K. Densities, viscosities, and velocity of sound of aqueous solutions are measured and they are used to evaluate the other parameters lik...

investigation of ammonium phosphate fertilizer influence on arsenic leaching in calcareous soils using soil columns

presence of arsenic, a heavy metal, in soil and water resources originating from geological formations of qorveh plain, which is considered as the main agricultural zone of kurdistan province in western iran, has put the agricultural products of this region at risk of pollution. since arsenate, as the most abundance form of arsenic in soil environment, competes against phosphate anion; applicat...

Synthesis and characterization of ammonium phosphate fertilizers with boron

The concentration of boron, an essential micronutrient for plants, presents a narrow range between deficiency and toxicity. In order to provide the boron requirement for plants, and to avoid toxicity problems, boron compounds are mixed with basic fertilizers. Sodium borate pentahydrate was used as a boron source. Ammonium orthophosphates fertilizers with boron were prepared by neutralizing phos...

Dual-setting calcium phosphate cement modified with ammonium polyacrylate.

alpha-Tricalcium phosphate bone cement, as formerly designed and developed by Driessens et al., consists of a powder composed by alpha-tricalcium phosphate (alpha-TCP) and hydroxyapatite (HA) seeds, and an aqueous solution of Na2HPO4 as mixing liquid. After mixing powder and liquid, alpha-TCP dissolves into the liquid and calcium deficient hydroxyapatite (CDHA), more insoluble than the former, ...
