| abstract |
A CHEMICAL SOIL IMPROVER NOTED FOR ITS COMPLEX EFFECTS AND COMPRISING TAR OBTAINED BY LOW-TEMPERATURE CARBONIZATION OF CAUSTOBIOLITHS. DEPENDING UPON CLIMATIC CONDITIONS AND PHYSICO-CHEMICAL CHARACTERISTICS, THE FOLLOWING ADDITIVES MAY BE INCORPORATED INTO SAID SOIL IMPROVER: ELEMENTAL SULFUR, FORMALIN, WASTES OF OIL SHALE PROCESSING INTO CARBOXYLIC ACIDS, SURFACTANTS OR PYRITE CINDER. THE CHEMICAL SOIL IMPROVER IS PRIMARILY INTENDED FOR SOIL STABILIZATION OR PLANTING, FOR THE CONTROL OF HARMFUL SOIL ORGANISMS AND WEEDS, FOR PRE-EMERGENCE CONTROL OF WEEDS, AND ALSO FOR INCREASING THE YIELDS OF DIVERSE CROPS IN ALL SOIL AND CLIMATIC ZONES. THIS INVENTION RELATED TO SOIL IMPROVERS OF CHEMICAL ACTION. |
