Oh what a mistake I've made. It seemed, that with all the diverse opinions expressed, that for clarity it would be wise to review again the definition of humus. In doing so I may have discovered the problem. According to the first 12-15 definitions provided by Mr. Google, no two were the same. There are some from Webster, from linguists, some local, some international, others from scientific journals, others from myriad "experts" and groups. Some say brown, some black, some black and brown, some wet, some dry, some arobic, some anaerobic, some equal to compost, or partial compost, or finished compost, or finished aged compost, or absolutely NOT compost, or plant based only, or plant and animal based, or it does not exist at all, or it lasts for eternity. In some cases it exists only in the presence of live plant roots, others say its found deep in pits. So, although I may be 100 IQ points short of understanding, I'm back to Mysterious, Magical, Molecular Poo. And, I love how it makes my tomatoes and peppers taste.
