THE METHOD OF TREATING SOIL TO PREVENT EROSION WHICH COMPRISES APPLYING TO THE SOIL SURFACE A LATEX COMPOSITION COMPRISING FROM ABOUT 0.5 TO ABOUT 10 PERCENT, BY WEIGHT, OF A WATER-INSOLUBLE RUBBER AND FROM ABOUT 0.005 TO ABOUT 0.5 PERCENT OF A WATER SOLUBLE COUNTER-PENETRANT FOR SAID RUBBER WHICH IS SELECTIVELY ADSORBED BY SOIL PARTICLES TO RENDER THE LATEX COMPOSITION UNSTABLE AND WHICH HAS PROTECTIVE COLLOID ACTION FOR THE COLLODIAL PARTICLES OF RUBBER IN SAID LATEX COMPOSITION SELECTED FROM THE GROUP CONSISTING OF NATURAL GUM, METHYL CELLULOSE HAVING A DEGREE OF SUBSTITUTION OF FROM ABOUT 1.2 TO ABOUT 2, A HYDROXYETHYL ETHER OF CELLULOSE HAVING A DEGREE OF SUBSTITUTION OF FROM ABOUT 1.5 TO ABOUT 3, ALKALI METAL SALTS OF CARBOXY METHYL CELLULOSE HAVING A DEGREE OF SUBSTITUTION OF FROM ABOUT 0.4 TO ABOUT 1.3, ALKALI METAL POLYACRYLATES, AN 0.5 PERCENT SOLUTION OF WHICH HAS A VISCOSITY OF FROM ABOUT 20 TO ABOUT 200 CPS. AT 30*C AND POLYACRYLAMIDE, SAID LATEX COMPOSITION BEING APPLIED IN AN AMOUNT BETWEEN ABOUT 0.25 AND ABOUT 5 OUNCES OF RUBBER PER SQUARE YARD, THEREBY PROVIDING A SUBSTANTIALLY CONTINUOUS FILM OF RUBBER INTIMATELY BOUNDED TO SURFACE SOIL PARTICLES THROUGH WHICH VEGETATION MAY GROW.
