The pyrolysis of fruit trees Pruning waste to be converted to biochar with microbial inoculation is a strategy improving the biological properties in calcareous soils. In order to investigate the biochar effect on some soil biological properties of the soil in the presence of microorganisms, a factorial experiment was carried out in a completely randomized design in the rhizobox under greenhous...

Inoculation experiments were carried out in pot culture to determine the effects of VA fungi on the growth of Poa bulbosa. In this experiment, four treatments  were  used: 1. Strile soil without  inoculation,  2. Strile soil plus inoculum, 3. Natural soil plus inoculum, and 4. Natural soil without inoculation. Inoculum was prepared from a suspension of mycorrhizal  roots of  Poa  plants (Root c...

Improving soil microbial activity and using symbiosis and synergistic relations between plant growth-promoting rhizobacteria (PGPR), arbuscular mycorrhizal fungi (AMF) and plants through improving nutrient uptake can cause better growth of plants especially at salinity tension condition. To investigate the effect of AMF and PGPR application on growth and some nutrient uptake by corn in differen...
