TIP #9

Don't take a good glass with you out into the garden to work, get one that doesn't mind getting dirty.

Nutrient List


NPK values for some common sources.

Note: unless specified I'm taking other people's word for the values, at least until the lab equipment arrives.

For the purposes of this list, "micronutrients" means they provide at least some of them, and "T" represents an itty bitty amount. Over time the dataset will improve, but keep in mind that in some instances; especially with natural materials, the listed values given are rough estimates and will vary with samples from different sources.
