The sewage sludge has been very effective because
it releases nitrogen into the soil for months, but we have also
noted several additional benefits: the soil warms more quickly because
it is darker in colour and lighter in weight; water evaporates at
a slower rate; earthworms are abundant; the soil is softer and less

and my bees!
