Most gardeners realize that plants need to be fed but know little to nothing about the nature of the nutrients involved or how they get into plants. Teaming with Nutrients explains how nutrients move into plants and what both macro-nutrients and micro-nutrients do once inside. It shows organic gardeners how to provide these essentials.

When we use chemical fertilizers, we injure the microbial life that sustains plants and then become increasingly dependent on an arsenal of toxic substances. Teaming with Microbes offers an alternative to this vicious circle and details how to garden in a way that strengthens, rather than destroys, the soil food web. You’ll discover that healthy soil is teeming with life - not just earthworms and insects, but a staggering multitude of bacteria, fungi, and other microorganisms.

Nothing has had a more profound impact on the development of modern civilization than thermodynamics. Thermodynamic processes are at the heart of everything that involves heat, energy, and work, making an understanding of the subject indispensable for careers in engineering, physical science, biology, meteorology, and even nutrition and culinary arts. Get an in-depth tour of this vital and fascinating science in 24 enthralling lectures suitable for everyone from science novices to experts who wish to review elementary concepts and formulas.

The restoration agriculture system described in this award-winning book works! It is possible for humans to produce staple foods using perennial agricultural ecosystems that actually improve the quality of the environment. This can be done on a backyard, farm, or ranch scale and is needed right now - on a global scale. Restoration Agriculture explains how we can have all of the benefits of natural, perennial ecosystems and create agricultural systems that imitate nature in form and function while still providing for our food, building, fuel, and many other needs.

By explaining the lean system for identifying and eliminating waste and introducing efficiency in every aspect of the farm operation, The Lean Farm makes the case that small-scale farming can be an attractive career option for young people who are interested in growing food for their community. Working smarter, not harder, also prevents the kind of burnout that start-up farmers often encounter in the face of long, hard, backbreaking labor. Lean principles grew out of the Japanese automotive industry, but they are now being followed by progressive farms around the world....

Learn a road map to healthy soil and revitalized food systems for powerfully addressing these times of challenge. This audiobook equips producers with knowledge, skills, and insights to regenerate ecosystem health and grow farm/ranch profits. Globally recognized soil advocate and agroecologist Nicole Masters delivers the solution to rewind the clock on this increasingly critical soil crisis in her first book For the Love of Soil. She argues we can no longer treat soil like dirt.

Hardly a day goes by that we don’t hear about someone committing a violent, reprehensible, even evil, act. And each time it happens, before we know anything about the circumstances, we are already sure of one thing: We are nothing like that perpetrator. But how can we be so sure? After all, we are all human. In Understanding the Dark Side of Human Nature, Professor Daniel Breyer takes us on a fascinating philosophical journey into many of the deepest and darkest questions that have engaged humanity for millennia.

There are 20 million acres of lawns in North America. In their current form, these unproductive expanses of grass represent a significant financial and environmental cost. However, viewed through a different lens, they can also be seen as a tremendous source of opportunity. Access to land is a major barrier for many people who want to enter the agricultural sector, and urban and suburban yards have huge potential for would-be farmers wanting to become part of this growing movement.

All ancient and indigenous peoples insisted their knowledge of plant medicines came from the plants themselves and not through trial-and-error experimentation. Less well known is that many Western peoples made this same assertion. There are, in fact, two modes of cognition available to all human beings - the brain-based linear and the heart-based holistic. The heart-centered mode of perception can be exceptionally accurate and detailed....
