Population densities of Belonolaimus longicaudatus, Pratylenchus brachyurus, and Trichodorus christiei were determined from soil samples taken weekly in Tifton, Georgia during a 14-month period (except for April and May) at 15-cm increments to a depth of 105 cm. Belonolaimus longicaudatus predominately inhabited the top 30 cm of soil that was 87-88% sand, 6-7% silt, and 5-7% clay. No specimens ...

in order to evaluate of pea, bean, lentil, wheat, rape and barley sensitivity to foramsulforun, rimsulforun and nicosulforun herbicides soil residue, a pot experiment was conducted at ferdowsi university of mashhad. experimental type was completely randomized design in factorial arrangement with three replications. treatments included herbicides (rimsulforun, foramsulforun and nicosulforun), he...

Physico-chemical properties of three Fadama farm site soils located in Ado-Ekiti, IkereEkiti and Ifaki Ekiti, all in Ekiti State, Nigeria, were evaluated. The parameters evaluated for were pH, particle size distribution, free Fe2O3 and Al2O3, organic matter, base saturation percentage and total exchangeable bases in eleven zones and thirty-three soil samples. The pH values showed that the soils...

the aim of this study was to investigate relationships between soil properties and plant species to determine the most effective factors separating vegetation communities in rineh rangeland. three stratifying variables were selected including slop, aspect and elevation. the study area was partitioned by combining these classes to generate homogenous units. 1m2 quadrates were located at sampling...

A method is described for efficiently concentrating enteroviruses from soil. Viruses were eluted from soil by mechanical agitation in high pH glycine buffer containing ethylenediaminetetraacetic acid. The eluted viruses were concentrated on a floc that formed de novo upon adjustment of the soil eluate to 0.06 M aluminum chloride and pH 3.5. Viruses not pelleted with the floc were concentrated b...

Visible and near-infrared diffuse reflectance spectroscopy (VIS-NIR) has shown levels of accuracy comparable to conventional laboratory methods for estimating soil properties. Soil chemical and physical properties have been predicted by reflectance spectroscopy successfully on subtropical and temperate soils, whereas soils from tropical agro-forest regions have received less attention, especial...

serum iron and total iron binding capacity anti percentage saturation were measured in 100 apparently normal individuals (50 men and 50 women) , the ages of the men were from ?2• 50 and of the women from 19-30, average serum iron in men was i33amgjloo ml and in women 112.5mg/ 100 ml, the average values for total iron binding ca paci ty were 306,?mg/ for men and ?90mg/ 100 rnl, for women, percen...
