Efect of carob sawdust application on soil properties in Chaco province
Soils with monoculture systems and intense tillage present a great loss of organic matter (OM). In this research work, the semi-incorporation of carob sawdust with different doses of nitrogenous materials was evaluated to improve soil properties.

In this research work, the semi-incorporation of carob sawdust with different doses of nitrogenous materials was evaluated to improve soil properties. The treatments were carried out with sawdust (A), urea (U), and manure (E) based on the expected C/N ratios. T1: control; T2: A (30 Mg.ha-1) + U (150 kg.ha-1); T3: A (30 Mg.ha-1) + U (438 kg.ha-1); T4: A (30 Mg.ha-1) + E (11.5 Mg.ha-1); T5: A (30 Mg.ha-1) + E (24.5 Mg.ha-1). After 3, 6, 9, and 12 months of semi-incorporation, the soil was sampled at 0-15 cm depth. Differences between the samplings in the chemical analyses with respect to the control were observed. The values of organic carbon and total nitrogen increased considerably. A tendency towards pH neutrality was observed in the first two samplings, favoring microbiological processes. Microbial respiration was higher in the treated plots compared to the control, mainly in the two treatments with cow manure. Soil bulk density decreased in T5 plots. It is considered that manure is the best option to be used with sawdust in mixtures. Since manure is a waste from livestock activity, it could enter into a low-cost agricultural-livestock scheme. In addition, it provides a greater amount of nutrients as opposed to urea which only provides N. On the other hand, the use of manure with a low N:P ratio could cause the accumulation of large amounts of P. Los suelos con sistemas de monocultivo e intenso laboreo presentan gran pérdida de materia orgánica (MO). En este trabajo se evaluó la semi-incorporación de aserrín de algarrobo, con distintas dosis de materiales nitrogenados, para mejorar las propiedades del suelo. Los tratamientos fueron realizados con aserrín (A), urea (U) y estiércol (E) en base a las proporciones C/N esperadas. T1: testigo; T2: A (30 Mg.ha-1) + U (150 kg.ha-1); T3: A (30 Mg.ha-1) + U (438 kg.ha-1); T4: A (30 Mg.ha-1) + E (11,5 Mg.ha-1); T5: A (30 Mg.ha-1) + E (24,5 Mg.ha-1). A los 3, 6, 9 y 12 meses de la semi-incorporación se muestreó el suelo a una profundidad de 0-15 cm. Se observaron diferencias en los análisis químicos entre los muestreos con respecto al testigo, aumentando considerablemente los valores de carbono orgánico y nitrógeno total. El pH tendió a la neutralidad en los dos primeros muestreos, favoreciendo los procesos microbiológicos. La respiración microbiana fue mayor en las parcelas tratadas con respecto al testigo, principalmente en los dos tratamientos en los que se agregó estiércol vacuno. La densidad aparente disminuyó en las parcelas de T5. Se considera que el estiércol es la mejor opción para acompañar al aserrín en las mezclas, ya que este es un desecho de la actividad ganadera que podría entrar en un esquema agrícola-ganadero con bajo costo, además de poseer mayor oferta de nutrientes en contraposición a la urea que solo aporta N. Por otra parte, el uso de estiércol con una baja relación N:P podría ocasionar acumulación de grandes cantidades de P. Instituto Agrotécnico "Pedro M.
