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.
John Pitkin Norton's is a comprehensive guide to the basic
elements of scientific agriculture. The notes contain all the major detail
related to the organic and inorganic contents of the plant, characteristics of
soil, and manures. Besides, it also deals with the utilization of crops as feed
to animals along with structure of milk and other dairy products. It is,
therefore, for people who are interested in scientific technology behind
agricultural practice, as this resource will provide a more comprehensive view
on how contributing factors go into effective crop production and
sustainability.
