Soil can be brown, black, crumbly, dry, wet-but so can dirt. So what's the difference? People often use the words "soil" and "dirt" to mean the same thing, but in science they are not the same at all. Soil is a material that plants can grow in, while dirt is the muddy footprints you leave on the floor on a wet day. Inside this book, readers will get down and dirty as they investigate what makes soil special and why dirt is something we need to wipe, sweep, or vacuum away.
What ingredients are in soil? Why is soil said to be living, whereas dirt is dead? And when it's under your fingernails, is it dirt or soil? Filled with information perfectly suited to the abilities and interests of an early elementary audience, this colorful, fact-filled volume gives readers a chance not only to learn, but also to develop their powers of observation and critical thinking.
With its stunning photographs and surprising, high-interest facts about a material that most of us take for granted, the book makes learning about soil a lively, engaging experience. What if we didnt have any dirt or soil?
Its hard to imagine. The ground would look different and many of the plants, trees and animals we know today would disappear. Dirt, and or soil, supplies a surprising variety of raw materials for making things. Learn about the ways dirt and soil have been used by humans over the centuries, from cave paintings to crop farming, and the exciting prospects for dirt and soil we may see in the future. Introduces soil and what is in it, discusses different types of soil, and explores which type of soil holds water best, is best for plants, and how worms help.
Community farms. Mud spas. Mineral paints. The world is waking up to the beauty and mystery of dirt. This anthology celebrates the Earth's generous crust, bringing together essays by award-winning scientists, authors, artists, and dirt lovers to tell dirt's exuberant tales. Geographically broad and topically diverse, these essays reveal life as lived by dirt fanatics - admiring the first worm of spring, taking a childhood twirl across a dusty Kansas farm, calculating how soil breathes, or baking mud pies.
Essayists build a dirt house, center a marriage around dirt, sink down into marshy heaven, and learn to read dirt's own language. Scientists usher us deep underground with the worms and mycorrhizae to explore the vast and largely ignored natural processes occurring beneath our feet. Whether taking a trek to Venezuela to touch the oldest dirt in the world or reveling in the blessings of our own native soils, these muscular essays answer the important question: How do you get down with dirt?
A literary homage to dirt and its significance in our lives, this book will interest hikers, gardeners, teachers, urbanites, farmers, environmentalists, ecologists, and others intrigued by our planet's alluring skin. The Jump Into Science book Dirt takes on the topic of soil, one of the most important resources on Earth.
A star-nosed mole is the book's character guide, and he shows off all the different kinds of dirt in his garden, helps us to understand how dirt formed and what's in it, and points out many of the incredible creatures who live in the dirt. Young readers will learn fascinating scientific information about the different soil layers, or horizons, and find out how the soil that plants grow in differs from the soil that building foundations sit in.
They'll also learn fun stuff: Did you know a single earthworm can eat several tons of soil a year? Dirt takes on more significance than just something to be cleaned up when you realize that it's a critical part of the web of life. Without it, plants could not grow, and animals - and people - could not live.
Soil is important, and it needs protecting. Dirt also discusses some of the issues surrounding soil conservation and protection and talks about protecting forests and grasslands as a way to help. A do-it-yourself experiment at the end of the book walks kids through a great activity - how to build your own soil ecosystem in a plastic soda bottle.
Give it some time, and you'll see grass begin to sprout and critters crawling around in your miniterrarium. The bright cheerful art, and the delightful mole will charm readers as they learn all the secrets of the precious substance down underground - dirt.
What if we didn't have any dirt or soil? It's hard to imagine. In Dirt to Soil Gabe Brown tells the story of that amazing journey and offers a wealth of innovative solutions to our most pressing and complex contemporary agricultural challenge--restoring the soil.
The Brown's Ranch model, developed over twenty years of experimentation and refinement, focuses on regenerating resources by continuously enhancing the living biology in the soil. Using regenerative agricultural principles, Brown's Ranch has grown several inches of new topsoil in only twenty years! The 5,acre ranch profitably produces a wide variety of cash crops and cover crops as well as grass-finished beef and lamb, pastured laying hens, broilers, and pastured pork, all marketed directly to consumers.
The key is how we think, Brown says. In the industrial agricultural model, all thoughts are focused on killing things. But that mindset was also killing diversity, soil, and profit, Brown realized.
Now he channels his creative thinking toward how he can get more life on the land--more plants, animals, and beneficial insects. The greatest roadblock to solving a problem, Brown says, is the human mind.
