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.

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.

Authored by Dr. K. C. Patel and Dr. Punit Mehta of Anand Agricultural University, this comprehensive PDF will cover all the essential topics related to soil science for students and professionals in agriculture. Starting with an introduction to soils, the book covers soil-forming rocks and minerals and the processes of weathering and soil formation. The text further outlines soil profiles and taxonomy, with a special focus on the soils of India and Gujarat. Various physical properties like soil water, air, and temperature are elaborated in detail in conjunction with soil colloids and reactions. Study of soil organic matter and several types of soil organisms, in order to learn how soils remain healthy and fertile, is included. This is a handy guide that will help one understand complexities in systems of soil and significance in agricultural practices.

This PDF is a comprehensive text that the department of soil science and agricultural chemistry at S.V. Agricultural College has developed on the different inputs necessary to improve agricultural productivity. The document is preceded by an introduction to bulky organic manures, where the amount lost at the time of collection and storage of farm yard manure (FYM) is reported. It deals with the preparation of composts, green manures, and terms of various organic wastes-terms like sewage and sludge. The book covers concentrated organic manures, biogas plants, and processes of manufacture of commercial fertilizers - both of nitrogenous, phosphatic, and potassic type. It also gives a rundown on mixed fertilizers and amendments, and secondary and micronutrient fertilizers. An essential feature is the Fertilizer Control Order, and thus this article becomes a fundamental reference point for understanding the role of fertilizers and manures in sustainable agriculture.

UC Davis course notes on soil chemistry include some of the interactions in the soil system. These include three-phase system of the soil; solid phase reactivity; and the chemistry of solutions within the soil matrix. Cation exchange reactions, soil buffering and pH dynamics, and redox reactions affecting chemistry in soil have also been covered. This resource has been very important especially for students who wish to understand the intricate processes by which chemicals regulate soil fertility and health and grant them knowledge that ensures effective soil management.
