BACKGROUND: Super absorbent polymers (SAP) by increasing the capacity of water storage and nutrition materials, reduction of wasting water and evaporation from the surface of soil improve crop production under water stress condition. Bio-fertilizers have the significant advantages to chemical fertilizers; for instance, they do not produce toxic and bacterial substances in the f...

There are some plants can replaced grass among cover plants. Cover plants are obvious solution of problem in these places that the most important plant is Frankinia and Lisimakia etc. The aim of this study is to use organic wastes, biological fertilizers and moisture super absorbents in the growth media of Frankinia to increase water holding capacity, delay in permane...

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...

One of the ways overcoming cost irrigation is through in-situ water harvesting at plant roots. Super absorbent polymer (SAP) can facilitate This study attempted to assess effect SAP on available (PAW) different soils. In this study, was sequentially added rate 0.2%, 0.3% and 0.5% soil weight its impact assessed in clay, sandy clay loam The moisture retention characteristics original treated soi...
