摘要: A B S T R C Intensive salmon farming generates organic residues which have a potential use in agricultural soils. The objective of this study was to evaluate the effect three sludge rates on potato (Solanum tuberosum) crop development and its residual annual ryegrass (Lolium multiflorum). field experiment carried out an Andisoil from Osorno Serie (Hapludands), located (40o35’S; 73o08’W), Chile. Treatment were (50, 100, 200 t ha -1 ), control (no fertilizer), inorganic fertilizer treatment. incorporated into soil then tubers cv. Yagana-INIA planted. After harvest, seeded. Total yield with 64.3 , significantly superior results (P ≤ 0.05). There no differences > 0.05) among fish (45.6 47.5 ) treatment (39.4 ). In addition, there tuber weight, but number per plant different Annual between treatments control. Salmon did not affect or increased P Olsen cation exchange capacity soil.
