Plant species affect soil bacterial diversity and compositions. However, little is known about the role of dominant plant species in shaping the soil bacterial community during the restoration of sandy grasslands in Horqin Sandy Land, northern China. We established a mesocosm pots experiment to investigate short-term responses of soil bacterial diversity and composition, and the related soil pr...

The microplot experiment was carried out on two soils (clay and sandy) with spring wheat fodder pea. In the experiment, effect of a granular product made basalt dust elemental sulphur content 1.5% tested. Fertilization in dose 30 kg/ha S pea 20 form basalt-sulphur granulate resulted significant increase methionine, cystine protein grain sandy soil. However, no these amino acids seeds observed. ...

A non-sodic, non-saline sandy loam soil was salinized to anion-cation ratios similar to those naturally occurring in Iraq and California. The interactions of saline soils (conductivities 4, 8, 12 and 16 mmhos/cm) with a moderately salt-tolerant plant (Lycopersicon esculentum 'Marimond') and a plant parasitic nematode (Meloidogyne javanica) were investigated. Plant parasitic nematodes were shown...

Investigations of the plant food requirements for sugarcane grown on the wind-blown, sandy soils of marine origin typical of the Natal coast, have. occupied the' attention, of numerous investigat6rsin past 'years. In some cases there has been shown to be little response to phosphate, whilst in the case of inorganic salts of potash and nitrogen a lack. of response or even a depressing effect on ...

Slow infiltration rates constrain effective and economical irrigation in some sandy loam soils in California. Polyacrylamide (PAM) has increased soil infiltration in some areas, especially in soils high in clay or silt. Field trials near Fresno, CA, with PAM failed to show improved infiltration. Laboratory experiments were conducted to investigate PAM effect on infiltration of various quality w...

This study assessed pesticide residues in soils, sediments, and vegetables in the Xuan Khe and Hop Ly communes located along the Chau Giang River in the Red River Delta, northern Vietnam. Samples were collected from agricultural areas within and outside of embankments built to prevent flooding. In Xuan Khe, the soils outside of the embankment were more clayey with higher organic matter contents...

Particleboard and solid wood stakes were treated with either an isocyanate or phenol formaldehyde resin and exposed in soil beds comprising three different soil types and two moisture contents. The treatments resulted in a marked improvement in the dimensional stability of particleboard but had no effect on solid wood. Higher moisture uptakes in stakes exposed in sandy soils indicated that the ...

Longidorus breviannulatus n. sp. was associated with stunted corn in Iowa. The nematode has wide bilobed amphidial pouches, a guiding ring 21-26 mum from the anterior end of the body, an odontostyle 81-88 mum long, and a spear extension 28-45 mum long. The most frequent collections and the greatest numbers of the nematode in the field occurred in sandy soils. Nematodes increased in greenhouse c...

The aim of the publication was to compare suitability foundation soils on basis table (standard empirical) bearing capacity. Four basic groups were compared, which are fine-grained soils, sandy gravelly and rocky soils. scientific motivation for this comparison is that visualizing difference between unsuitability a particular soil / rock one fundamental problems in engineering geology. Quantify...
