    Phosphorus sources (P) plus filter pie with or without azotofos on the available P in the soil

    The objective of the investigation was to evaluate the effect of four phosphorus sources plus filter
\npie with or without the biofertilizer Azotofos on the available phosphorus in the soil at different moments after
\nthe treatment. An experiment in factorial design 4(2)+1 was established, being the four phosphorus sources:
\nrock phosphate, natural phosphate, triple phosphate and Cuban phosphoric rock; two sources of the organic
\ncompound to base filter cake enriched with Azotofos microorganisms, only filter cake (without enrichment) and
\na control treatment (without filter pie, neither Azotofos), with three repetitions. The evaluations of the tenor of
\navailable P (Bray-2) were carried out at the 30, 60, 90, 120 and 150 days after the installation of the experiment.
\nThe tenor of P (Bray-2) was influenced by the sources of P and the enrichment with biofertilizantes (factorial)
\nincreasing the tenor of available P in front of the control. The triple superphosphate promoted the higher tenors
\nin P in the soil at 60 and 90 days after its application, independently of the presence or not of the organic
\ncompound enriched with P solubilizing microorganisms, although this effect didn’t stay stable at the time.
