At the GreenThumb conference I was privileged to take a class from NYCHA’s Rob Benneton on soil quality. (Side note: I had such a great time that I went to the website to see what other workshops they offered, and I found one on gardening that’s being hosted at a local community center next week. I called to register, and was told that since I don’t live in an NYCHA development, I’m not eligible. That got me to look around the site to see what the requirements are to qualify for NYCHA. An individual (not family) can make up to $43K and receive assistance. If any of you fall within that range and feel ok about the government helping you with your rent, please apply, then go to the workshops and take notes for me.)
Okay, back to soil quality. Initially I was going to summarize my notes, but I think instead I will spread this out over a few weeks and focus on more manageable sections. Today, let’s look at what soil is. An abbreviated WikiAnswers definition:
Soil is material capable of supporting plant life.
Dirt is soil which has been depleted of the characteristics which give it the ability to support plant life. (I guess you could call it “dead soil”?)
Soil is formed from glaciation and weatherization of rock, which is a key reason that soil type varies depending on the region. Its parent material affects its particle size and density.
Soil is a combination of minerals, organic matter, air, water, and living organisms. Plants (including of course trees, herbs, fruits, vegetables) need water, oxygen, light, and nutrients. Soil is the primary source of nutrients for plants, so healthier soil will result in healthier plants.
Next time we will look at soil quality indicators– the physical, chemical, and biological ways to determine the health and make-up of the soil.
