Hydrogels are known to adsorb a large amount of vapor and liquid water, making them good candidates enhance the dew condensed from atmosphere. Although water adsorption invasion in hydrogels have been object many studies, condensation has only little investigated. We address here process on hydrogel grains widely used agriculture (Aquasorb 3005TM). show that condensing is enhanced when compared...
abstract in this study the effects and costs of application of two kinds of super absorbent polymer on the establishment and surviving of seedlings was investigated. experiments were done in the field and on two kind of soil with different salinity (ec: 4.5 and 8 dsm-1). the results showed: the establishment rate of seedling in control was about 40 percent. the percentage of seedling establishm...
Container and bare-root seedlings are the two basic stock types used in reforestation programs many countries, but tropics, have never been widely applied. The objective of this research was to assess possibility for tropical forest landscape restoration treated by fertilization nursery aquasorb treatment using tree species, i.e., Calophyllum inophyllum Gmelina arborea . A randomized block desi...
Lack of sufficient water resources and drought stress is one of the main problems for crop production in arid and semi-arid regions of the world, such as Iran. The use of water absorbing polymers (hydrogels) improves water retention capacity of soils and can lead to optimal use of the restricted water resources. In this research, the effects of four levels of Aquasorb water-absorbing polymer (0...
This research investigated the effects of super absorbentpolymers on root characteristics of Avena fatua under two soil textures and three irrigation regimes. The study was arranged according to a factorial experiment based on a completely randomized design with three replications. Hydrogel compositions included three types of super absorbents (Aquasorb, Boloorab A and Stockosorb) with two leve...
بحران و کمبود آب در مناطق خشک خصوصا در ایران، برای توسعه کشاورزی و همچنین، به منظور گسترش پوشش گیاهی در طرح های بیابان زدایی به عنوان عامل مهم محدود کننده محسوب می شود. دستیابی به راهکارهایی که بتواند بهره وری آب را افزایش داده و هزینه ها را کاهش دهد، هدف بسیاری از پژوهش ها، از جمله این پژوهش می باشد. این پژوهش در بخشی از عرصه بیابانی تحت تأثیر فرسایش بادی واقع در شهرستان آران و بیدگل انجام ش...
In this study, the impact of three different types of activated carbon (AC) on the bioaccessibility of 14C-phenanthrene in non-sterile and sterile soils was investigated. A single dose (1%) of each of the different AC (CB4, CP1 and AQ5000) was blended with soil spiked with 50 mg·kg−1 of 12C/14C-phenanthrene. The mineralisation of the 14C-phenanthrene was monitored over a 14 day incubation perio...
Direct seeding, a planting technique that has long been applied in restoring degraded land and forest, is often doubted to be successful due many constrains, both biotic abiotic. This study aims increase the success of direct seeding through application seed briquettes, aquasorb treatment determining right sowing time for three forest tree species, i.e. Ceiba pentandra, Enterolobium cyclocarpum...
