The secret to richer, carbon-capturing soil? Treat your microbes well. Imagine if someone invented machines to suck carbon out of the atmosphere — machines that were absurdly cheap, autonomous, and solar powered, too.
Wouldn’t that be great? But we already have these gadgets! They’re called plants. The problem is, plants die. So there’s one hurdle remaining: We have to figure out how to lock away the carbon in dead plants so that it doesn’t just return to the atmosphere. This has left people scratching their heads. Clive Kirkby was one of those government agents urging farmers to leave dead plant residues in their fields.
As he was proselytizing, Kirkby began to bump heads with an agronomist named John Kirkegaard. This made Kirkby crazy. “I’ve been returning the stubble to the ground now for six years, and it’s just not going into the soil,” Kirkegaard told him. Kirkby knew that there must be some mysterious quirk of this topsoil ecosystem that was thwarting him. The idea that drove Kirkby was elegant in its simplicity. Soil. Soil is the mixture of minerals, organic matter, gases, liquids and a myriad of micro- and macro- organisms that can support plant life.
It is a natural body that exists as part of the pedosphere and it performs four important functions: it is a medium for plant growth; it is a means of water storage, supply and purification; it is a modifier of the atmosphere; and it is a habitat for organisms that take part in decomposition and creation of a habitat for other organisms. Soil is considered the "skin of the earth" with interfaces between the lithosphere, hydrosphere, atmosphere, and biosphere. Soil consists of a solid phase (minerals & organic matter) as well as a porous phase that holds gases and water. Accordingly, soils are often treated as a three-state system. Overview
Soil. An important factor influencing the productivity of our planet's various ecosystems is the nature of their soils.
Soils are vital for the existence of many forms of life that have evolved on our planet. For example, soils provide vascular plants with a medium for growth and supply these organisms with most of their nutritional requirements. Further, the nutrient status of ecosystem's soils not only limit both plant growth, but also the productivity of consumer type organisms further down the food chain. Figure 1: Most soils contain four basic components: mineral particles, water, air, and organic matter. Organic matter can be further sub-divided into humus, roots, and living organisms.

How to Assess Soil Composition. The health of garden plants depends on the soil's composition — the proper balance of mineral pieces, organic matter, air, and water.
Knowing the type of soil you have can help you choose techniques to enhance its good qualities. The best garden soil should have proper balance of minerals, water, organic matter, and air. The relative amounts of clay, silt, and sand particles determine your soil texture: Clay particles are microscopic and flat. Silt particles are more angular and larger than clay but still microscopic. 8 Steps for Making Better Garden Soil.
Starting to build a new garden isn’t difficult.
Most people begin by going out into their yards with a shovel or garden tiller, digging up the dirt and putting in a few plants. Following the organic and natural methods, add a little mulch or compost, and you’re well on your way to make good soil for your homegrown vegetables. But in the long run, the success of your garden depends on making healthy garden soil.

By Phil Williams Wednesday, May 7, 2014, 9:19 AM The types of “weeds” that grow seemingly spontaneously in your garden are telling you valuable information about your soil and microclimate if you care to listen. There are certain “weeds” that appear when the soil has been degraded to rehabilitate the soil back to life, or simply as a protectant cover when we leave the soil bare, and open to the elements. These unappreciated plants do all the hard work to make their home eventually no longer suitable for themselves. Plantain If you have hard compacted soil, expect “weeds” with strong taproots to show up to bust up the compaction. The Importance of Carbon in the Soil. Tolerate drought better. Organic matter acts like a sponge, soaking up extra water and releasing it when needed.
Grow larger and more vigorously. Plants grown in soil with abundant organic matter receive a slow release of nutrients all season. Resist pests and disease. Healthy plants are naturally resistant to pests and disease. Understanding the Soil. Quotes from Understanding the Soil Processes Most of us will agree that the soil is the major natural resource available to mankind. Yet it is and has been abused by us to the point of self destruction. Many past civilizations have perished due to their abuse of the soil (like Mesopotamia and the Mayan civilization). Why didn't anyone stop the destruction? The soil destruction process takes time and the changes in each generation are "small" so no one cared-and most of us still don't. The soil in which we plant crops today has been self perpetuating for millions of years without man's help.
