    Abstract: Calibration of soil test P could be a stage in determining P fertilizer rates to meet plant P requirements and soil nutrient availability of phosphorous. The objective of this study was to determine the critical phosphorous (Pc) and phosphorous requirement factor (Pf) for maize production in the district. Field experiments, which were laid out in a...

    Abstract: Congo red has strong tinting strength, low price that it was used in meat dyeing. Amino acid ionic liquids (AAILs) containing amino acid cations or anions are synthesized from natural amino acids, which has the characteristics of low toxicity. Nowadays, Fe3O4@SiO2@AAIL composites has seemly not been reported for the separation/analysis of congo red... Show More
