"Alpechín" and "vinaza", by-products from the olive and sugar beet processing industries, respectively, were used for irrigating and ferti1izing annual crops. The influence of the addition of these two products on the chemical and physical properties of a vertic xerofluent soil, and on crop development and production was studied. A rotation of maize (spring-summer) and lettuce (winter) was estalished on eight plots of 25 m2. Three different treatments with "alpechín" and vinaza" were applied to six of the plots. The other two plots were fertilized and irrigated conventionally. Electrical conductivity of soil solution, bulk densi ty, infil tration rate and water profile of the soil were affected by the treatments. The first maize crop showed no clear differences in development and production between the various plots, but in the second maize crop remarkable influences of the treatments were found. The 1ettuce production decreased as the doses of "alpechín" and "vinaza" increased. |
