We currently are using similar practices to rebuild soil health on our homestead. We don't use chemicals, encourage natural growth in areas, use non dyed mulch that decomposes and a little to no till as possible gardening methods.
Building Soil Part 1
After my previous post about plants and soil, a friend suggested that I explain the best ways to build soil...
So, how do we build soil? Before we can answer that question, we must define what soil is. Soil is the combination of a mineral base and organic matter that provides ideal habitat for the "soil food web".
The mineral base is derived from eroded bedrock, glacial drift, volcanic deposits, etc. The texture of this mineral base can be expressed as sand, silt, loam, or clay. Many of the nutrients plants need are found in this mineral base.
The other component of soil is organic matter. This is made up of living and dead plant, animal, and fungal material. The plant material is obvious, but what where is all this animal material coming from? Decaying large mammals typically contribute very little to the soil, although their waste can play a part. But what if you don't have large animals, do you still have animal material in your soil?
Yes, of course! Small mammals, reptiles, and invertebrates play a part as well, but the vast majority of non-plant material in the soil is too small to see with the naked eye. Microbes! Microbes (including fungi, even though they're not animals...) make up much of the soil's organic matter and play a vital role in the function of soil.
Without microbes, plants can only absorb water-soluble nutrients. Many of the nutrients plants need from the soil are not found in a form they can absorb. Whether in the mineral base or decaying material, plant nutrients can get "locked up" or, even worse, leach out of the soil entirely.
Microbes "unlock" nutrients in the soil and make them available to the plants. Microbes, and soil organic matter as a whole, can also serve as a reservoir for nutrients to keep them from being lost to leaching. Poor soils are low in organic matter and microbial diversity. High quality soils have a relatively greater percentage of organic matter and microbial diversity.
The "soil food web" is made up of many plants, animals, and fungi living and dying; working together in beautiful harmony.
Without organic matter all we really have is dirt. Our job as gardeners and farmers is to turn depleted dirt back into soil. Now that we have a rough understanding of what soil is, we can further explore how to "make" soil.
We'll cover the role of plants next...
