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.

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.
These are comprehensive
lecture notes from UBC that give foundational understanding on soil science. The
document accounts for topics such as the components, classification, biology,
and nutrient dynamics of soil. For that reason, it is ideal study material for
students starting their time learning in soil studies. The material bases its
study on the significance of soil management practices and the impacts of such
practices on agricultural productivity. This resource allows learners through
clear explanations and examples to gain knowledge which is paramount about what
the role of soil is in supporting plant life and a larger ecosystem.
