Rangelands are very diverse, and they spread from low vegetation desert areas to those with more rainfall and more cover In saline and desert areas, there are many restrictions on vegetation establishment, hence the use of amendments. The study area is located south of Nazarabad city in Alborz province, Iran. In this study, different amendments, such as mineral biochar, arbuscular mycorrhiza fu...

objective: returning crop residue to the soil exerts favorable effects on physical and chemical properties of soil. in fact, the plant residues can affect soil conditions such as ph and important role in soil fertility and cycling of elements in the soil may have. in addition to the role of the organic matter from decomposition of crop residue in increasing the concentration of micronutrients i...

The biological stability of soil organic carbon (SOC) is influenced by the chemical structure of SOC and the existence of various mechanisms of protection offered by soil minerals and their spatial arrangement within the soil matrix (Baldock and Skjemstad, 2000). In addition to defining the potential availability of SOC to decomposer organisms living in soils, the chemical structure of SOC also...

the aim of this study was to investigate the effect of reforestation on physical and chemical soil properties particularly soil carbon storage in the berenjastanak forest. forestations were including acer velotinum boiss., fraxinus excelsior l., populus nigra l. and pinus brutia ten. a witness forest with mixed species was selected as region potential. four soil profiles were drilled in each fo...

In cotton and cereals production systems, the most important cause of soil fertility degradation is the inappropriate crop residues management. In a long-term experiment carried out from 1982 to 2012, the effects of crop residues management (CRM) during 30 years on soil chemical properties and crops yields were evaluated in a cotton-cereals rotation. The experimental design was nonrandomized bl...
