The application of SP either singly (treatment 4) or in
combination with M. endolithica (treatment 6) or PRP either
singly (treatment 5) or in combination with M. endolithica
(treatment 8) significantly (P < 0.05) decreased soil pH levels
and increased the concentration of soil available P compared
to the treatments which included the application of the
actinomycetes without the addition of P (treatments 2 and 3)
or the control (treatment1)(Table4).The available P content of
the soil was significantly (P < 0.05) higher in treatment 6
compared to treatment 8 (Table 4).
