Leaching of nutrients from sandy soil fertilized with pig manure on Alstroemeria culture
An experiment was conducted in pots under greenhouse conditions on Alstroemeria (Alstroemeria aurantiaca D. Don) culture, cultivar 'Napoli'. Two different types of pig slurry, pig slurry and thermal dried pig slurry, were applied as fertilizer. The aim was to evaluate the possible pollution effect, on leaching nutrients of the two pig slurry. Rates studied were 0 (without fertilization), 1 (the rate 1 covered the nitrogen culture requirement) and 2 (the double of 1). The nutrients concentration of the leaching depended of water leached volume. Four leaching by pot were made, on spring, summer, autumn and winter. The NH4 +-N, NO3 -N, phosphorus and potassium, variables were studied. The methodology to adjust estimation and to compare the models was the nonlinear mixed model. Treatments pig slurry and thermal dried pig slurry and the two rates, 1 and 2, were different significantly. The thermal dried pig slurry treatment and the 2 rate were the most polluting for the four studied variables.
