A method of ameliorating acid soils so as to enhance plant growth is provided by adding to soil 0.05 to 20 percent by weight, based on the weight of the soil, of a flue gas desulfurization by-product consisting essentially of 80-99 percent by weight of gypsum (CaSO.sub.4.2H.sub.2 O) and 1-20 percent by weight of magnesium hydroxide (Mg(OH).sub.2).

A method of collecting and conditioning either or both of a fluid bed combustion cyclone or bed ash, from a sulfur-containing petroleum coke combustion, by transferring dry combustion ash, containing anhydrous calcium sulfate and resultant lime to a pneumatic tanker, transferring the tanker with the ash to a storage site, and discharging the dry ash through a mixing pump onto the storage site while adding sufficient water to hydrate anhydrous calcium sulfate and resultant lime in the ash and provide about 7-25 percent by weight excess water in the ash.
