New generation soil conditioners was applied to sodic soils in various procedures. In flocculation tests, followed by wet-sieving, particle sizes were approximately four to five times larger with new soil conditioners than with an older soil conditioner (Krilium) or with controls. Water penetration was greatly improved on a sodic soil when conditioned with the new soil conditioner. A Natrargid soil was amended with NaCl, NaHCO/sub 3/, and NaOH to give different degrees of sodicity. Application of polyacrylamide in soil in all the soils increased seed emergence and dry weights of tomato seedlings.
