Abstract
LONDONO ALVAREZ, Adriana; MONTOYA GOMEZ, Diana Cristina; LEON PELAEZ, Juan Diego and GONZALEZ HERNANDEZ, Maria Isabel. NUTRIENT CYCLING AND NUTRIENT LOSSES IN ANDEAN MONTANE FORESTS FROM ANTIOQUIA, COLOMBIA. Rev. Fac. Nac. Agron. Medellín [online]. 2007, vol.60, n.1, pp.3717-3734. ISSN 0304-2847.
Gravitational flow and its chemical composition were measured in montane oak forests (Quercus humboldtii), in pine (Pinus patula) and cypress (Cupressus lusitanica) plantations in Piedras Blancas, Antioquia ( Colombia ), over two years. Zero tension lysimeters were used at different depth soil levels. The highest gravitational flow value at highest depth (50- 80 cm) was obtained in cypress plot ( 492,7 mm), followed by pine ( 14,2 mm) and oak forest ( 2,0 mm). A similar behavior was encountered for nutrient losses, following the same pattern as gravitational flow. Thus, for oak, pine and cypress, nutrient losses were respectively: Ca: 0,004, 0,084 and 2,270 kg ha-1 y-1; P: 0,008, 0,052 and 1,234 kg ha-1 y -1; Mg: 0,004, 0,022 and 0,667 kg ha-1 y-1. K losses were 0,08 and 7,092 kg ha-1 y-1 for oak forest and cypress plantation respectively. Nutrient losses followed the next order for each type of forest: oak: K>P>Ca>Mg, pine: Ca>Fe>P>Mg>Zn>Mn, and cypress: K>Mn>Ca>P>Fe>Zn>Mg.
