Teaming with Microbes
Their argument boils down to one sentence: "No one ever fertilized an old-growth forest". Think about all the wild places you have ever seen, lush with growth. How did they get that way without the help of Scott's or Miracle-Gro? And if Scott's and Miracle-Gro are so superior, why don't our yards and gardens look better than those wild places?
The authors' thesis is that we should garden like Nature gardens, working with the flora and fauna in the soils rather than against it through the use of compost, organic mulches and actively aerated compost tea. Best of all, they provide precise instructions and call for materials that most of us have on hand anyways. No need for expensive ingredients or equipment!
I was thrilled to discover that I am not a "lazy composter" as I have always thought. Instead, I practice cold composting (not turning the compost), a method that produces the most "nutritious" compost! And what I jokingly refer to as "composting in situ", using the mower to shred up leaves and dumping them with the grass clippings onto my beds in the fall is actually a recommended mulch. As are the leaves I leave in my gardens over the winter. The only thing I am doing wrong is removing the leaves in the spring. And my deepest, darkest secret is nothing to be ashamed of. Instead of carefully working my compost into the soil, I just spread it on top. Again, a recommended method for amending the soil!
Of course, there are things that I have to do differently. Such as leaving the leaves on my beds. And even though I don't roto-till, I should still stop "loosening" the soil in the spring when I plant my seeds. The soil should be disturbed as little as possible. Planting in individual holes or narrow furrows is fine. I should learn to make and use actively aerated compost teas. Perhaps most importantly instead of throwing anything and everything into my composter, I should pay closer attention to the individual ingredients and their proportions, maybe go so far as to have different composters to make compost tailored to the needs of the various plants in my gardens.
This is a wonderful book that I will be referring to again and again.
