Plant litter is an important factor for soil conservation and sustainability that could modify soil chemical properties and increase the plant biomass production. The aim of this research was to compare plant litter chemical composition and its effects on soil properties in three species including Hordeum bulbosum, Poa bulbosa, Bromus tectorum. First, soil samples were taken in the depth of 0-3...
Soils are extremely rich in biodiversity, and soil organisms play pivotal roles in supporting terrestrial life, but the role that individual plants and plant communities play in influencing the diversity and functioning of soil food webs remains highly debated. Plants, as primary producers and providers of resources to the soil food web, are of vital importance for the composition, structure, a...
In order to use natural compounds in controlling plant pests and diseases, many researchers in recent years have studied the antifungal effects of essential oils and plant extracts. The purpose of this study was to investigate the chemical composition and antifungal effects of Echium khuzestanium and marubbium anisodan extracts. After extraction and preparation of di...
