In the first section of this book on
soil erosion, an introduction to the soil erosion problem is presented. In
the first part of the second section, rainfall erosivity is estimated on the
basis of pluviograph records and cumulative rainfall depths by means of
empirical equations and machine learning methods. In the second part of the
second section, a physically-based, hydrodynamic, finite element model is
described for the computation of surface runoff and channel flows.
Soil Fertility book presents nine chapters written by renowned soil
fertility experts from Africa, Asia and South America. The book is divided into
two sections. Section 1, Biological Processes and Integration of Inorganic and
Organic Fertilizers for Soil Fertility Improvement, examines biological
processes that can enhance the soil fertility. The second section,
Improving Fertilizer Recommendation and Efficiency, looks at the
state-of-the-art in leaf sampling and analysis.
