Red-backed salamanders were observed to see how they colonized the forest edges of northern forests. By quantifying the surrounding abiotic factors, we predicted favorable abiotic factors. We set up 27 artificial habitats in a cedar swamp, mature hardwood forest, and a plot that was burned in 1936 at the forest edge, middle and interior. Soil and air temperature, light intensity, humidity, soil...

A field experiment was conducted to study the response of wheat and rice to potassium during 2004-05. The basal dose of N at 120 kg, P2O5 at 90 kg ha -1 was applied with K levels to both wheat and rice crops. Wheat variety Naseer 2000 and rice variety IRRI 6 were used in the study. The experiment was carried out in R.C.B design with three replications. Potassium application significantly increa...

Brassica oleracea L. var. capitata L.) and beetroot (Beta vulgaris L.) was obtained at 2075 and 4505 mg kg 1 Ni In situ remediation (phytostabilization) is a cost-effective solution in soil, respectively. On the muck soil containing 1200 for restoring the productivity of metal-contaminated soils and protection of food chains. A pot experiment with wheat (Triticum aestivum mg kg 1 Ni, the predic...

Pollination sustains biodiversity and food security, but pollinators are threatened by habitat degradation, fragmentation, loss. We assessed how remaining forest influenced bee visits to flowers in an oil palm-dominated landscape Borneo. observed six plant species: four crops (Capsicum frutescens L. “chili”; Citrullus lanatus (Thunb.) Matsum & Nakai “watermelon”; Solanum lycopersicum “tomato”; ...

Field monitoring of volumetric soil water content (VWC) is critical for a variety of applications. Recently developed electronic soil water sensors provide a relatively inexpensive monitoring option. However, the calibration of these sensors is more sensitive to variations in soil properties than for time domain reflectometry (TDR), which is generally regarded as the best electronic means of VW...

of agricultural P to water quality. In Florida, FHANTM 2.0 (Field Hydrologic and Nutrient Transport Model, Pollution of surface waters by P from agricultural areas is a water version 2.0; Fraisse and Campbell, 1997) was developed quality issue in Delaware. The FHANTM 2.0 computer model can help identify areas with a high potential for P loss, but the model’s to simulate water and P movement fro...

Developing the concept of soil quality may help identify the soil and crop management practices required for environmentally, socially, and economically sustainable agriculture. Objectives of this paper are (1) to review current efforts to define soil quality, (2) to discuss factors and processes which influence soil quality, (3) to identify, soil and crop management practices that affect proce...

To evaluate the effect of gypsum and manure on the yield and quality of sugarcane and properties of sodic soils, an experiment was conducted on farmer’s field at Dosehra area, District Charsadda during Kharif 2004. Ten treatments comprised of control (T1), gypsum @ 25 % of the soil requirement (T2), gypsum @ 50 % (T3), gypsum @ 75 % (T4), gypsum @ 100 % (T5), farm yard manure (FYM) @ 20 tons ha...
