“…The calcareous materials within the soil profiles interact with these nutrients and fix them as calcium cation; thus, whatever fertilizers are added to the soil become fixed within the (Abdal et al, 2002). Although optimally, fertile soil that supports maximal plant growth requires higher concentrations of these nutrients than the ones detected, it was observed that neither survival nor plant growth in the selected trees was affected, which may have been due to the positive growth promoting effect of bioremediated soil (Suleiman et al, 2005).…”

“…The soils of Kuwait are sandy in nature; their texture constitutes from 71.6 to 94.8% sand, 2.4 to 14.9% silt and 2.8 to 13.5% clay (Abdal et al, 2002). It is alkaline soil with limited organic matter (<1%), having very low content of plant nutrients and high amounts of calcareous materials.…”

“…The highest soil temperature is usually recorded in August (38.6 • C) and the lowest is recorded in January (5.1 • C). Soil water holding capacity is low (7%) with high infiltration rate (50-100 cm/h) and high evaporation (3000 mm) (Abdal et al, 2002).…”

The role of the Conocarpus lancifolius tree in remediaitng oil-contaminated soil, which was bioremediated using conventional methods, was investigated. The selected tree was used to phytoremediate bioremediated oil-contaminated soil for three successive growing seasons. At the end of the phytoremediation experiment, 85.7% of measurable total petroleum hydrocarbon (TPH) was degraded in Conocarpus lancifolius rhizosphere, and the detectable concentrations of some poly aromatic hydrocarbons (PAHs) were less than 0.02 ppm. A number of hydrocarbon degrading microorganisms (HDMs) were isolated at 35 • C under aerobic conditions, and were identified using 16S rRNA gene sequencing and fatty acid methyl ester (FAME) analysis. The efficiency of the isolated HDMs in degrading a mixture of hydrocarbon compounds (HC) was assessed. Among the bacterial isolates, Rhodococcus equi was distinguished from the other isolates because of its efficient degradation of some compounds in the HC mixture.Samples were also collected from Conocarpus lancifolius vegetative parts and were analyzed for heavy metal and mineral accumulation. The results demonstrated that the Conocarpus lancifolius tree was able to uptake high levels of chromium (Cr), vanadium (V), and nickel (Ni) and accumulate them in the tree's roots. Additionally, Conocarpus trees tolerated high concentration and accumulated several metals in all plant tissues. These metals included aluminum (Al), calcium (Ca) and iron (Fe).

“…Calcite and gypsum in the soil affect plant nutrient solubility, mobility and availability and 35 percent of dry soil is calcium carbonate (Abdal et al , 2002; Suleiman and Abdal, 2000; Abdal et al , 2002; Abdal and Suleiman, 2002). Accordingly, the addition of fertilizers to the existing soils has minimal impact on the plant's growth and development, as the fertilizer trace elements (particularly iron (Fe), zinc (Zn), boron (B), chlorine (Cl), manganese (Mn), copper (Cu), phosphate (P) and molybdenum (Mo)) are fixed or bound up with other elements in soil, unavailable to the plant.…”

PurposeThe present study aims to determine the residue levels in the soil and water prior to, and after fertilization, as previous soil investigations in Kuwait indicated that different types of fertilizers are used leaving residues in the soil, in order to assist the prospective farmers in choosing environmental sound chemicals for each crop. The importance of the following is to determine the geologic conditions of the soil in such a productive farm area and the effect of the use of fertilizers.Design/methodology/approachTo achieve the study purpose soil and water samples were collected over a wide area and chemical parameters (pH, electrical conductivity (ECe), cations (Ca+2, Mg+2), and anions (CO3−2,HCO3−,Cl−)) were obtained via the suitable and most appropriate chemical analyses.FindingsThe soils have several levels of calcareous contents along with varying salinity and alkalinity. Before fertilization on average, soil ECe ranges from 0.93 to 4.37 mS/cm, pH from 7.4 to 7.60, cations 8.00 to 36.00 meq/l, and anions from 4.85 to 29.61 meq/l. After fertilization pH ranges from 7.09 to 7.47, ECe ranged from 3.79 to 12.85 mS/cm, cations ranges from 29.75 to 66.36 meq/l, and anions ranges from 15.18 to 63.32 meq/l; showing that ECe, cations and anions average values has increased by almost three to four orders of magnitude. Furthermore, ECe, pH, cations, and anions values have sharply increased with depth. The evidence from this study shows that vertical leaching adversely contributes to the deterioration of the groundwater quality and rate.Practical implicationsThe output of this study is intended to be the building block or the nuclei for a data bank on the prevailed agricultural practices in different aspects, and upon which further studies on the southern area of Kuwait will depend.Originality/valueThe farm areas in the southern region of Kuwait state (case study: Al‐Wafrah farms) suffer from misuse and mismanagement of the agricultural lands in different aspects. This paper provides new source of information on the historical record of farm development and the nature, performance and results of the associated agricultural practices in such areas, as so to be the base or the starting point form which further studies can go forth.

Hydrocarbon-degrading microorganisms (HDMs), associated with the rhizosphere of Conocarpus lancifolius and Ficus infectoria trees grown in bioremediated soil, were isolated under controlled laboratory conditions. The selected trees were used to phytoremediate oil-contaminated soil for three successive growing seasons. At the end of the phytoremediation experiment, 85.7% of measurable total petroleum hydrocarbon was degraded in the rhizosphere soil associated with Conocarpus lancifolius compared to 78.6% in the rhizosphere of Ficus infectoria. The detectable concentrations of some polyaromatic hydrocarbons were less than 0.02 ppm. The HDM isolation process was conducted at 35 degrees C under aerobic conditions. The isolated HDMs were identified using 16S rRNA gene sequencing and fatty acid methyl ester analysis. Differences in the genera of the isolated HDMs and their assessed efficiency in degrading a mixture of hydrocarbon compounds between the two trees were noted.
