Evaluación del efecto de la intensidad de labranza en la formación de costra superficial de un oxisol de sabana en los Llanos Orientales de Colombia. II. Caracterización física en superficie

The outlined methodology in this article allowed correlating soil sealing and soil physical properties as structural stability, infiltration velocity, soil loss erosion, run-off, normal and torsion resistance and aggregate distribution. The output showed that improved pastures after eight years of sowing produced a relatively positive response to soil erosion and mechanical...

Dinámica del cadmio en suelos cultivados con papa en Nariño, Colombia.

The mobility of cadmium and fixation in soils cropped with potatoes in Túquerres, Pasto and Guachucal Nariño, Colombia was evaluated. Samples with an auger of 11 cm diameter and 40 cm in length were taken. On these soil samples applications of 0, 50, 100 and 150 ppm cadmium were, and incubated during a 4 month period under field capacity. In this soils the content of total...

Evaluación de la asociación bacterias fijadoras de nitrógeno - líneas interespecíficas de arroz-nitrógeno, en Typic haplustalf. Ibagué, Colombia

The study was carried out at the Cauchitos farm, Ibague municipality department of Tolima, with bounds: North 4°23'51" and west 75°9'7", 979 ansm, the average temperature is 24,3°C, tropical dry forest (bs-t) in the Holdridge classification.

Efecto de cuatro métodos de labranza sobre las propiedades físicas y la pérdida de suelo en la rotación papa-pastos en áreas de ladera en una región alto andina de Colombia

This study evaluated the loss and the changes in the soil physical properties, and the production of yellow potato Solanum phureja, as a result of four tillage systems (Human traction, THT; Animal traction, ATT; Mechanical, MT; and Mechanical combined, CMT) in Santa Lucia, Tuluá municipality, high andean region of Colombia to 2.870 masl. Treatments were evaluated using a...
