Agricultural Engineering Soil Mechanics


Book Description

This book provides an introduction to classical soil mechanics and foundation engineering, and applies these principles to agricultural engineering situations. Theoretical design formulae are given, plus tables and graphs dealing with bearing capacity factors, wall pressure factors, soil cutting numbers and soil mechanical properties. Many example problems of design and analysis are solved in the text, and there are unsolved problems given for each chapter.The text begins with descriptions of soil origins and classification systems, including agricultural classification schemes, and then introduces classical concepts of soil strength and strength measurement techniques in the laboratory and in the field. Soil mechanics is applied to the design of shallow foundations, and the design formulae as well as tables of bearing capacity factors for design use are provided. New research and design findings in the specialized area of tall and heavy farm silos are also given, in addition to deep pile foundation design for heavy structures on very soft soils. Water flow in soils is treated, together with stability of ditch bank slopes and small earth dams, design of retaining walls and pressure pressures in bins and silos, soil erosion and protection methods, soil cutting and tillage design methods, soil compaction analysis, the use of geotextiles and problems of soil freezing.The book is directed primarily at professional university students in Agricultural Engineering, but will also be of interest to scientists working in other engineering branches, landscape architecture, soil physics and the like.

Engineering Plants for Agriculture


Book Description

Agriculture plays a vital role supporting human life on Earth but faces significant challenges because of population growth, plant pathogens, and climate change. Genetic engineering of crops promises to increase food yields, create drought- and pest-resistant crops, and improve nutrition in the developing world. Written and edited by experts in the field, this collection from Cold Spring Harbor Perspectives in Biology examines the molecular bases of different plant characteristics and how they can be manipulated genetically using modern molecular biological techniques. The contributors review recent advances in our understanding of plant plasticity, circadian rhythms, stomatal development, inflorescence architecture, symbiotic phosphate acquisition, and specialized plant metabolism and discuss how this knowledge might be used to boost yields, improve tolerance to pathogens and environmental stress, and enhance nutritional content. Several chapters are devoted to the development of specific genetically modified plants (e.g., disease-resistant cassava and submergence-tolerant rice) and their agronomic and socioeconomic impacts. The generation of blight-resistant American chestnut trees--the first bioengineered plants developed with the goal of ecological restoration--is also described. This volume is therefore an essential read for all plant biologists, geneticists, and engineers interested in addressing agricultural as well as environmental challenges.

Mechanics of Agricultural Materials


Book Description

The importance of economical production of agricultural materials, especially crops and animal products serving as base materials for foodstuffs, and of their technological processing (mechanical operations, storage, handling etc.) is ever-increasing. During technological processes agricultural materials may be exposed to various mechanical, thermal, electrical, optical and acoustical (e.g. ultrasonic) effects. To ensure optimal design of such processes, the interactions between biological materials and the physical effects acting on them, as well as the general laws governing the same, must be known.The mechanics of agricultural materials, as a scientific discipline, is still being developed, and therefore has no exact methods as yet, in many cases. However, the methods developed so far can already be utilized successfully for designing and optimizing machines and technological processes.This present work is the first attempt to summarize the calculation methods developed in the main fields of agricultural mechanics, and to indicate the material laws involved on the basis of a unified approach, with all relevant physico-mechanical properties taken into account.The book deals with material properties, gives the necessary theoretical background for description of the mechanical behaviour of these materials including modern powerful calculation methods and finally discusses a large number of experimental results. Many of them can only be found in this book. Special attention is paid to the unified approach concerning theory and practice.The systematic treatment of the material makes the book useful to a wide circle of designers, researchers and students in the field of agricultural engineering. The book can also be used as a textbook at technical and agricultural universities.
