| La producción intensiva de salmones genera residuos orgánicos que tienen un uso potencial en suelos agrícolas, existiendo escasa información publicada de su utilización. El objetivo del presente estudio fue evaluar el efecto de tres dosis de lodo de salmón en el desarrollo del cultivo de papa (Solanum tuberosum) y su efecto residual en ballica anual (Lolium multiflorum). El ensayo se estableció en un suelo Andisol de la serie Osorno (Typic Hapludands), ubicado en Osorno (40º35S, 73º08O), Chile. Los tratamientos fueron tres dosis de lodo (50, 100 y 200 t ha-1), un control (sin fertilización orgánica e inorgánica) y un tratamiento de fertilización inorgánica. El lodo se incorporó al suelo, posteriormente se plantó papa cv. Yagana-INIA y después de la... |

| Currently in Chile, there is a lack of tools to determine the real-time nutrient contribution of slurries. This study aims to evaluate three quick tests for their accuracy in estimating the total contents of N (TN), P (TP), K (TK), and ammonium-N (N-NH4+) in dairy slurries. The quick tests included the Agros Nova Meter, Quantofix N Volumeter, and a hydrometer. While the Agros and Quantofix meters directly measure the ammonium-N content; the hydrometer indirectly estimates the total content of N, P, and K based on linear relationships with the slurry DM. Samples (73) were collected from dairy farms along Southern Chile (39° to 44° S and 71 to 73° W). Analyses were carried out on laboratory conditions using conventional techniques as well as using each of... |

| An intact lysimeters study was carried out to measure the potential nitrogen (N) losses on an andisoil of Southern Chile with different fertilisers. The treatments tested were: fish slurry (FS), dairy slurry (DS), potassium nitrate (IF) and a control treatment (C), with no N addition. An equivalent amount of 150 kg of total N ha-1 was applied to each lysimeter and then the equivalent to 1260 mm of rainfall was irrigated over a 90 days period. Leachate samples were analysed for nitrate, nitrite, ammonia and organic N (No). Total N losses were calculated as the product between drainage and the respective N concentration in the leachates. Lowest N losses were obtained in the control and FS treatments (66 kg N ha-1) and the greatest amount was obtained in the... |
