Abstract

Whey Permeate (PS) could be used as fertilizer and nutrients to the soil. Saline and sodium content can damage it. The response of silo corn and alfalfa was evaluated in Natrustol soil en the east center of Córdoba (Argentina). The doses was between 30 and 120 m 3 PS / ha. Production, physical and chemical soil properties were measured up to 30 cm. Production not increase; the Nt, P, Ca and interchangeable Na increased. There were no differences in organic matter, cation exchange capacity, interchangeable K; salinity and pH. The Nt and P are mobile in the soil profile: risk of groundwater contamination. The highest doses deteriorate the stability of aggregates, the hydraulic conductivity (Ks) and the optimal water interval (IHO). It is recommended doses from 30 to 60 m 3 / ha of PS, measuring PS composition, monitor Nt, P, Na in the soil profile, Ks and the density to estimate the IHO.
