Soil microorganisms are very interesting subjects to study especially in arid lands such in Saudi Arabia. In my laboratory we are studying the following:-
1- The ability of native Sinorhizobium meliloti to fix nitrogen for alfalfa production, and by the use of PCR-DNA we hope to produce an inoculum feasible to Saudi soils condition (Salinity, dry and high temp.).
2- The impacts of graywater re-use for irrigation on the soil microorganisms, and the human health.
3- The Effects of pesticides on soil microbial population and activity.
4- Forest soil microbial populations and its roles in the fertility of the soil.
It is a Ghost or it is a microbe, we need to know every thing about it but, actually our knowledge is still…….?.
