Principles and practices of agricultural analysis

This is a very enlightened online material that has gone into deep detail on the methods and principles of agricultural analysis, especially concentrating on the chemistry of phosphates. While elaborating on general analytical processes that should be used while carrying out agricultural research, Wiley also goes ahead to give detail method for analyzing mineral phosphates and phosphoric acid. The general text introduces numerous techniques in the realm of analytical determinations, including the citrate method and volumetric determination, amongst others, and the importance of possessing the right titration in agricultural chemistry. The book will also take great length discussing chemistry involved in the manufacture of superphosphates, which is inevitable in improving soil fertility. Of special benefit to students, researchers, and other professionals in agricultural science are the broad foundational knowledge provided in the book that applies in academic and practical settings.

Practical Manual Agriculture Chemistry

It is a comprehensive manual useful for students and practitioners in agricultural chemistry mainly dealing with techniques for soil analysis. The whole process elaborated goes from collecting and processing soil samples up to analyzing soil profiles and characteristics, from determining soil density, moisture content, and maximum water holding capacity to hydraulic conductivity and assessment of soil texture. The manual also touches on some critical measurements: soil temperature, electrical conductivity (EC), pH, and cation exchange capacity. These contain detailed methods and practical applications that provide necessary skills in the effective analysis of soils, thereby adequately practicing agriculture and crop management.

Analytical Chemistry Notes by Alagappa University

This comprehensive PDF delves exhaustively into various aspects of analytical chemistry, maintaining its focus both on the conceptual as well as the practical aspects. It first begins with errors in chemical analysis, pointing out the differences between precision and accuracy of results in experimental work. It further leads the reader into various tools for data analysis, comparison of results, and more importantly, electrochemical methods like polarography and cyclic voltammetry. Among these are chromatographic techniques that involve gas chromatography, high-pressure liquid chromatography, and ion chromatography. These illustrate the power of these techniques for chemical substance separation and analysis. The discussion on purification techniques and ionic separations makes this paper an invaluable resource for students and professionals wishing to advance their knowledge on analytical methodologies.

Fundamental Calculations in Analytical Chemistry

Authored by Alatzne Carlosena Zubieta and Jose Manuel Andrade Garda, this concise PDF serves as a must-read in formulating the conceptual calculations carried out in analytical chemistry. Units and terms of concentration relevant to the pdf will help obtain clarity in defining concentrations of solutions. The procedures given for the preparation of solutions from both solids and liquids also list what happens before analysis, such as drying, dissolution, digestion, and extraction. It addresses concepts like dilution and concentration, which test solutions contain, useful to discuss and clarify with students or even the practicing personnel who might want to refresh their math in chemical analysis.
