Rm. Palma et al., Nutrients in the soil of a forest in Chaco (Argentina) - Relation to plantspecies and seasonal variability, AGROCHIMICA, 45(3-4), 2001, pp. 108-114
The aim of this work was to assess the influence of the species Espina Coro
na (Gleditsia amorphoides (Griseb.) Taub), Guayaibi (Patagonula americana L
.), Mora (Chlorophora tinctoria (L) Gaub.) y Urunday (Astronium balansae En
gl.) on C, N and P soil contents and to study the seasonal differences of t
hese properties. The study site was located at the Estricta Natural Reserva
tion. Chaco Province, Argentina. Total N. organic C and available P didn't
differ significantly (p < 0.05) throughout the year in the total forest, wh
ile significant differences ( p < 0.05) beetwen species for total N and org
anic C were found. Respiration C and mineral N differed significantly (p <
0.05) throughout the year and between species too.
