Book Description
Soils are one of the world's most important resources, and their protection, maintenance, and improvement is critical to the continuance of life on earth. Soil Fertility, Second Edition, offers thorough coverage of the fertility, composition, properties, and management of soils. This book carries on the tradition of excellence established by authors Henry Foth and Boyd Ellis, leading soil scientists whose previous books in this field have become multi-edition classics. The Second Edition of Soil Fertility has been significantly expanded to include more information on mineralogy, while keeping the thorough coverage of essential topics. The book presents soils as dynamic, constantly changing bodies, and relates soil fertility and management to the mineralogy of their origin. Four new chapters offer updated information on soil charge properties, ion adsorption, exchange and fixation, and soil reaction. There is also a far greater emphasis on environmental issues, reflecting the increasing importance of environmental concerns to agronomists and soil scientists today.

Book Description
Terra preta is the Portuguese name of a type of soil which is thought to have almost miraculous properties. The newspapers are flooded with reports about "black gold," scientists believe that two of the greatest problems facing the world - climate change and the hunger crisis -- can be solved by it. The beauty of it is that everyone can do something about it because since 2005 the secret of producing this black soil has been revealed -- and it is a secret that seemed to have been lost forever with the downfall of the once thriving Indian culture of the Amazon basin. The recipe is astonishingly simple as all you need are kitchen or garden wastes, charcoal and earthworms, so it can be produced on every balcony or on the smallest of garden plots. The authors set off on a treasure hunt and condensed all the knowledge about the world's most fertile soil into a convenient guidebook. In addition to a sound instruction manual on producing terra preta and organic charcoal (biochar), the handbook covers fundamental principles from climate farming to closed-loop economy. It makes a passionate plea against synthetic fertilizers and genetic technology

Book Description
It is becoming more relevant to explore soil biological processes in terms of their contribution to soil fertility. This book presents a comprehensive scientific overview of the components and processes that underpin the biological characteristics of soil fertility. It highlights the enormous diversity of life in soil and the resulting effects that management of land can have on the contribution of this diverse community to soil fertility in an agricultural context.

Book Description
The land beneath our feet gives life. Soil gives plants a place to grow. It is a natural resource that has shaped the way we live. However, we use it for more than just growing things. We grind up soil to create paints. We shape it into pottery. We heat it to make bricks for building homes and monuments. Color photographs, fact boxes, a hands-on activity, and "Words to Know" add more detail to this earth science book.

Book Description
Dr. Benjamin Wolf has made a valuable contribution to growers and students alike with this comprehensive book written as a result of 50 years of experience consulting growers of numerous crops. You will discover many farm practices and other media (such as soil preparation, use of machinery, and correction of pH and salt levels) that affect the three growing components. Specifically, you will gain vital information about how to modify soils to maximize growing potential; soilless approaches that still provide maximum air, water, and nutrients; how air, water, and soil affect crop production; balances necessary for maximum growth; and various farm practices and how they affect crop growth.

Book Description
"Nature works and has been working for a billion and a half years-ever since there were living things on earth. This is important. We talk of controlling nature, but any wise farmer or stockman knows that nature makes the rules for us to learn and follow, if we can. In short, the ecologist is in a position to furnish us, in many ways, models which we can follow in our own operations. Before the prairies were settled, plowed and fenced, wild herds moved back and forth across them, never staying in one place after the grass was cropped too short. These moving herds distributed minerals from their droppings and remains, for it is well-known that wild animals usually maintain a good mineral balance by visiting salt-licks and varying their pasture-grounds. Here in a nutshell is the model for proper use of grasslands. It takes a lot of common sense to get across the information we need. He has it and can put it out so we can all understand it."--Wheelers.co.nz.
