What constitutes high quality in finished compost?
Compost quality cannot be measured merely with a look at its color, a sniff, and a feel. Neither can it be established by what is not in it. Of course the appearance needs to resemble crumbly moist soil, but its performance needs to be evaluated. How will the compost affect plant growth? How well was the organic material converted to humus? The product needs to have the energy to support plant growth for many months. Thorough laboratory analysis has been designed specifically to analyze compost, evaluating how effective the compost process was in allowing beneficial biological activity.
