Agricultural Engineering Vol. 2



Introduction

​Agricultural engineering volume 2 explores engineering involvement in soil and water conservation, agricultural material properties, processing and handling as well as farm structure requirement, farmstead layout, storage structures and construction, animal housing requirements among others. 

The book undoubtedly provides essential engineering fundamentals required by students for effective teaching and practical training in skill acquisition and is therefore, recommended for all students of agricultural and engineering technology students in training at different levels in the university, polytechnic, colleges and vocational schools.
