Valoración de la capacidad nutriente de diferentes turbas españolas

Abstract

[ES] — En el presente trabajo se estudia la capacidad nutriente de diferentes turbas españolas, mediante la técnica de la electroultrafiltración. Las turbas muestran en general un bajo contenido en P y K y abundante N total con predominio del N orgánico de baja capacidad reactiva. En general muestran: baja actividad microbiana, baja capacidad para movilizar su proprio N y elevada capacidad para inmovilizar el N que pudiera añadirse al suelo como fertilizante. Para su empleo como fertilizantes deberían suplementarse con P y K. El N necesita una reactivatición mediante el encalado en las turbas acidas y la adición de pequeñas cantidades de otros materiales orgánicos que aceleren los mecanismos de mineralización.

[EN]The nutrient capacity of different peats from Spain has becn studied by means of electroultrafiltration technic. Low contents of K and P were generally observed with peats, while the N total contení was quite high, mainly the organic form with low reactive capacity. The peats showed: low microbial activity, low capacily to mobilize own N and great capacity to unmobilize the N that might have been added as a fertilizer. In order to use them as fertilizers, K and P must be added, as well as Hile quanlities of organic materials to increase the mineralizalion mecanisms; a liming vvould also reaclivale ihe N, especially in the acid peats.
