any of you guys apply compost regularly? how much do you charge? any advice on choosing a good compost, applying it, etc...? what do you think about a product called Numus, which is a pelletized compost? would you think this would work the same? half the benefit? is compost fine sitting out in the sun for the whole summer? example: i buy say 30 cubic yards of it in the spring, but only use half. will the compost work the same in the fall? should i cover it? does anyone use it to suppress diseases? i appreciate any help on the above questions or any information, books, sites, etc. on compost. thanks.
