Soil: It is much more than Dirt
Why is soil important?
For too long, we have cared too much about what the soil can do for us, and each year it grows a little more tired, depleted, susceptible to pests, disease and water shortages, and we are all responsible. “It is up to us, farmers, ranchers, soil scientists, legislators and consumers, to invest in our soil once again. —Soil Health Institute
Healthy Soil – It’s in the Organic Matter!
There is an exciting ecosystem living under our feet!
Microbes perform critical functions in soil food webs, such as decomposing organic materials, cycling nutrients, and improving soil structure. (USDA NRCS)
Soils high in organic matter will:
- Absorb and retain water to help crops even through dry spells.
- Provide nutrients for healthy root and plant growth for more bountiful crops.
- Enhance microbial biodiversity and activity, which can help in the suppression of diseases and pests.
- Resist erosion and compaction.
“Making” healthy soil…
Advancements in the science and biology of soil is captivating scientists, environmentalists, corporations, and governments around the world. The potential of healthy soil goes far beyond the success of this year’s harvest. D2D will explore more of this topic in future posts.
Now, when taking fork to mouth, be sure to thank the millions of good bacteria that fed the soil that helped make your nutritious dinner. Remember, without soil, we wouldn’t exist!
The Bottom Line:
We cannot underestimate the importance of soil. It is the foundation for our food and well-being. It must be managed and cared for in order to to sustain the population of today as well as the population of our future.
