WATER ABSORBING GEOCOMPOSITE: A NOVEL METHOD IMPROVING WATER AND FERTILIZER EFFICIENCY IN Brunnera macrophylla CULTIVATION. PART II. PROPERTIES OF THE MEDIUM AND MACROELEMENT UPTAKE EFFICIENCY

Efficiency of superabsorbents in improving water productivity

Agricultural residues and various other materials are currently being used as additives to improve the physical and chemical properties of soil. Iran is located in an arid and semiarid region, so using strategies to reduce water use will reduce the problem water scarcity. The use of superabsorbent to increase water uptake and retention is one of the solutions that have been applied to improve w...

wuthering heights and the concept of marality/a sociological study of the novel

to discuss my point, i have collected quite a number of articles, anthologies, and books about "wuthering heights" applying various ideas and theories to this fantastic story. hence, i have come to believe that gadamer and jauss are rightful when they claim that "the individaul human mind is the center and origin of all meaning," 3 that reading literature is a reader-oriented activity, that it ...

Maize response to water, salinity and nitrogen levels: yield-water relation, water-use efficiency and water uptake reduction function

Water, salinity and nitrogen are the major factors affecting maize production in arid and semi-arid areas. The objectives of this study were to investigate the effects of different water, salinity and nitrogen levels on yield-water relationships, water use, water productivity (WP), water use efficiency (WUE) and water uptake reduction function by maize hybrid SC-704 in a semi-arid area and ...

simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...

Soil water regime and water concervation efficiency in a non-irrigated semi-arid environment
