The desert, which covers around one-third of Earth’s continental surface, is defined as the harshest terrestrial environment and comprises a highly extensive biome ecosystem. Microorganisms are key drivers that maintain integrity desert ecosystems. Over past few decades, desertification has increased owing to changes in rainfall patterns global warming, characterized by land degradation, loss m...

Visualization of molecular structures aids in the understanding of structural and functional roles of biological macromolecules. Macromolecular transport between the cell nucleus and cytoplasm is facilitated by the nuclear pore complex (NPC). The ring structure of the NPC is large and contains several distinct proteins (nucleoporins) which function as a selective gate for the passage of certain...

objective: soil organic carbon has been the most important soil quality measurement factors and has intense relation with soil physical, chemical and biological characteristics. organic matter and its components are important factors of soil aggregates constitution and stability and play significant role in its structure. so, this research has been done for achieving this purpose. methods: this...

Use of saline water for irrigation has shown considerable promise. However, its effect on the solubility and bioavailability of native soil nutrients is not well understood. This study was conducted to evaluate the effects of salinity on the behavior of zinc(Zn) in calcareous soils. The soil samples with different physiochemical properties were collected from four locations in Khorasan province...

Demand for products made from the dry mass of Asian ginseng (Panax ginseng) is growing, but harvest limited by fungal disease infection when replanted in same field. Rotated cropping with maize can cope replant limit, it may take decades. We aimed to amend post-maize-cropping farmland soils cultivating ginseng, using effective microorganisms EMs and fulvic acid (FA) additives detecting comparin...

Spent mushroom compost (SMC) substrates are commonly used as growth media for greenhouse crops and horticulture production. This study aimed to investigate the responses of physiochemical soil properties, enzyme activities, microbial community compositions different cultivation durations SMC treatments on tomatoes. The experiment included following treatments: substrate surrounding after planti...

soil is a nonrenewable source that needs considerable management to prevent physical deteriorationby erosion and compaction. compacted soil causes low fertility and yield. the purpose of this study isto investigate the effect of viscoelastic properties of soil and to determine important factors oncompaction. furthermore, stress distribution, prediction of soil compaction and simulation of its e...
