Effect of soil solarization for soil sterilization on population densities of soil fauna at Fayoum Governorate, Egypt
|
|
| Abstract |
Soil solarization was used to control root-knot nematodes,
soil borne diseases, and root-rot disease and provide weed control.
Solarization is method to control soil biota by solar heat
and does not involve chemicals or toxic material. This method is
economical and easily implemented in Mediterranean and
tropical regions where hot summers occur. The aim of this
study was to investigate the effect of soil solarization on activity
density of soil fauna. Soil solarization was accomplished by
covering irrigated soil with transparent 0.03 mm thick polyethylene
sheets for 8 wk during July - Aug. Population dynamics of
soil fauna were observed and recorded before and after solarization.
The success of solarization depends on climatic conditions,
soil texture, and sensitivity of soil fauna to heat and humidity.
The true spider decreased from 2.5 in the control to 1.6
under solarization, Collembola increased from 0.5 to 1.2 but
Formicidae decreased from 1.5 to 0.6 and Orthoptera decreased
from 1.3 to zero. This means that inoculation by useful species
of soil fauna must be a necessary step to improve the value of
soil solarization.
