Chemical engineering is finding extensive application in two important phases of agriculture, the preparation of fertilizers to enrich the soil and the better utilization of waste agricultural products. The second phase has been studied at Iowa State College, particularly in regard to corncobs and oat hulls. They contain pentosans, which can be converted to furfural, a potentially valuable product. Cobs may be destructively distilled to yield useful products including a char which can be highly activated. Cobs or oat hulls may be treated with a phenol to form a black resin which can be manipulated into a valuable insulating and decorative material.
