Effects of different culture media on rooting of Urtica dioica L. stem cuttings

  In the present study, the rooting behavior was evaluated for stem cuttings of one of medicinally important plant, Urtica dioica L. Among four treatments of rooting media which includes field soil, sand, small sand and water, average of rooting in field soil was highest. There were no differences in root production between macro sand and water treatments. The same patterns occurred with root weight...

Evaluation of fertility status and irrigation potentials of selected Fadama soils in Adamawa State, North-eastern Nigeria

  The study was conducted to determine the fertility status and irrigation potentials of selected Fadama soils in Adamawa State, North-eastern Nigeria. An area of about 54 ha of Fadama land was randomly selected within each site based on their usage for intensive irrigation agriculture. Three transects that are 300 m apart were cut in each of the Fadama areas. Four sampling points that are 150 m apart...

Mapping and screening risk assessment of heavy metals concentrations in soils of the Bahr El-Baker Region, Egypt

  Mapping the spatial distribution of soil pollutants is essential for delineating contaminated areas ofBahr El-Baker Soils, Egypt. Geostatistical interpolation and kriging was used to estimate pollutant levels in soils. The X- Ray Fluorescence (XRF) and X- Ray Diffraction (XRD) analyses results showed similarity of the studied soils in the most of chemical and mineralogical (dominant montmorillonite)...
