Productivity in desert ecosystems is primarily limited by water followed by nitrogen availability. In the deserts of southern California, nitrogen additions have increased invasive annual plant abundance. Similar findings from other ecosystems have led to a general acceptance that invasive plants, especially annual grasses, are nitrophilous. Consequently, reductions of soil nitrogen via carbon ...

A field study was designed to study several inorganic soil amendments as a substitute for sand in the top-dressing of an aerified, sandbased putting green. Several forms of natural zeolites, calcined clays, and diatomaceous earth were blended with sand and used to backfill aerification holes on a sand-based putting green. Several of these amendments enhanced turfgrass recovery and quality in th...

Irrigation with untreated effluent in periurban agriculture could result in accumulation and bioconcentrations of cadmium (Cd) and lead (Pb). Different amendments were used to investigate their effect on availability, concentration, and uptake of metals by wheat in texturally different soils. Crop was irrigated with water containing Cd and Pb at 20 mg L−1, thereby adding 260 mg pot−1 of each me...

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...

     Developing strategies to tackle water stress in lawns in arid climate regions is significantly important. In such conditions, using growing media amendments as well as native plants can relieve drought stress in different growing stages of the plants. This study was carried out to investigate the effects of some types of soil amendments on the emergence and early seedling establishment of ...
