The purpose of this web
resource is to provide fundamental concepts for managing nutrients in tropical
soils and container crop production. Topics covered includes: Soil composition,
Soil profile Factors that cause differences in soil behavior and performance,
Goals of Modern Nutrient Management, Soil-Nutrient Relationships, Soil Acidity
and Liming, Essential Nutrients, Soil Fertility Evaluation, Fertilizer Material,
Fertilizer Placement.
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.
This class
presents the application of principles of soil mechanics. It considers the
following topics: the origin and nature of soils; soil classification; the
effective stress principle; hydraulic conductivity;
stress-strain-strength behavior of cohesionless and cohesive soils and
application to lateral earth stresses; bearing capacity and slope stability;
consolidation theory and settlement analysis; and laboratory and field methods
for evaluation of soil properties in design practice.
This volume is designed to be a complete
manual for all but amateur cultivators. The object of this volume is to
condense, and present in an intelligible form, all important established facts
in the science of soil-culture. The author claims originality, as to the
discovery of facts and principles, in but few cases.
This note covers the
following topics: the goal of soil biology management, why should land managers
understand soil biology?, the underground community, what controls soil
biology?, general management strategies, considerations for specific land uses,
cropland, forestland, rangeland, assessment and monitoring.
