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.
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.
