    James, D. W. (David W.), 1929-
    Abstract:
    The physico-chemical reactions of ammonia in soils and clays have many practical and theoretical implications. On the one hand, large quantities of anhydrous ammonia are used annually in agriculture for fertilizer; the dry gas is applied directly to the soil by simply injecting it below the ground surface. On the...

    Abstract:
    Traditionally, livestock operations were small and combined with cropping operations. This allowed farms to be self-sustaining because nutrients were constantly recycled on the farm. Since the Haber-Bosch chemical process was patented, crop farmers turn to industrial fertilizers when soils nutrients are depleted. Animal and plant operations diverged, functionally separated, and...
