Abstract: A versatile process and apparatus is presented for producing, in high yields, many different grades of pulp from a single wood specie or for pulping any specie or type of woody material, and for storage and recycling of the by-product liquid and gaseous materials. The process of this invention is virtually pollution free, and the reactant chemicals are recoverable from the by-products. In the alternative, the by-products themselves have a commercial value which may forestall recovery of the reactants. The lignin constituent extracted from the pulp is usable as a resin binder, a wood rehardening agent, or a glue.

Abstract: A soil supplement for addition to potted plants consisting of microorganisms, enzymes, and various substances rich in protein and carbohydrates including bone meal, torula yeast, potassium citrate, soybean flour and durum wheat flour. The potassium citrate acts as a chelating or sequestering agent. The substance is used in connection with the water used to moisten the soil of the potted plant. The effect of adding the supplement to the soil is that the microorganism count greatly increases due to the microorganisms and enzymes acting on the various substances rich in protein and carbohydrates. The sequestering agent tends to maintain the solution in suspension through the earth. As water and/or the supplement are added to the soil from time to time, any salts accumulated on the surface of the soil or on the edge of the pot are gradually sequestered into the soil and are ionized by the action of the enzymes and microorganisms to produce minerals useful for the plant.

Abstract: Iron (FE) may be reacted in the presence of an alkaline material with vegetable tannin by mixing water (H.sub.2 O), comminuted iron in its elemental state and vegetable tannin to form an iron chelate which holds iron in a form available to and assimilable by plants. Treatment of plants with the iron chelate supplies iron thereto and corrects iron chlorosis. Comminuted cast iron and vegetable tannin extract may be used, respectively, as the Fe and vegetable tannin sources. Further, comminuted redwood, which is known to be poisonous to many plants in its natural state, is believed to be converted into a nonpoisonous growing medium which supplies iron to plants and stimulates plant growth by reacting the vegetable tannin naturally occurring in the redwood to form the aforementioned iron chelate therein.
