« The value of adding organic matter to the soil in the form of animal manures, green manures, and crop residues for producing favorable soil tilth has been known since ancient times »
« And since plants have shown their ability to absorb and translocate the complex molecules of systemic insecticides, they can no longer discredit the idea that plants are able to absorb the soluble humic nutrients, containing by far ... »
« Synthesis of fulvic acid (1a) was accomplished by a route involving selective ozonization of 9-propenylpyranobenzopyran (1c), obtained by a regioselective cyclization of the 2-methylsulphinylmethyl 1,3-dione(3c) »
« The issue has also been approached by redefining ‘humic substances’ as the portion of soil organic matter that cannot be molecularly characterized or by calling all soil organic matter ‘humus’. We argue that this compromise - maintaining terminology but altering its meanings in varying ways — hampers scientific progress beyond the soil sciences.The [need for accurate models] of soil organic matter does not allow a confusing middle path; it requires leaving the traditional view behind to bring about lasting innovation and progress. This is critical as scientific fields outside the soil sciences base their research on the false premise of the existence of ‘humic substances’. Thus an issue of terminology becomes a problem of false inference, with far-reaching implications beyond our ability to communicate scientifically accurate soil processes and properties. »

« Humus accounts for 50 to 90% of cation exchange capacity. Like clays, humus colloids and high surface area char hold nutrient cations »
