Abstract:
As part of a larger study, this chapter investigates the influence of different
fertilization practices on microbial parameters involved in P turn-over of Mediterranean
soils. More precisely, the aim of the present study was to compare the effects of both
mineral and organic amendments on microbial patterns involved in P recycling of two
Mediterranean soils. With this aim, the effects of both Na and K phosphate salts (supplied
as NaH2PO4 and KH2PO4, respectively), as well as sewage sludge compost (SSC) on both
acid (APH) and alkaline (BPH) phosphatases and phosphodiesterase (PDI) activities,
BPH/APH ratio, densities of culturable heterotrophic bacteria and available P (P Olsen)
were investigated in two Mediterranean vineyard soils originating from calcareous and
siliceous mineral parent materials. All of the amendments were carried out in order to
provide soil with a P total quantity equivalent to 0.5 g P2O5 per kg of soil, and variables
were measured after 25 and 87 d of incubation under field conditions. Globally, results
showed that neither phosphate salts nor SSC had significant effects on P mineralizing
enzyme activities, nor on the densities of culturable heterotrophic bacteria. On the
contrary, all of these amendments resulted in a significant increase in available P of the
two soils considered. Results also showed a significant effect of the incubation time on
several variables, especially APH and BPH activities, as well as available P. Indeed,
between the two sampling dates most of these enzyme activities significantly decreased,
whereas P availability was improved, SSC amended soils showing the more important
variations in available P contents. This fertilization experiment also revealed that soil
origin had only a significant effect on BPH activities, and that the nature of the cation
(i.e., Na or K) within the different P salts used did not show any significant effect on the
different variables investigated.
