Increasing wildfire activity in Alaska's boreal forests has led to greater fuel-reduction management. Management has been implemented to reduce wildfire spread, but the ecological impacts of these practices are poorly known. We quantified the effects of hand-thinning and shearblading on above- and belowground stand characteristics, plant species composition, carbon (C) and nitrogen (N) pools, a...

This study determined the performance and heavy metals uptake of kenaf at different levels of compost application in textile effluent polluted soil. Polluted soil was collected from the vicinity of a textile company in Nigeria. Twelve-litre plastic pots were filled with 10 kg soil. Soil amendments applied were: 0 (control), 60 Kg N ha -1 of N.P.K 20:10:10 (recommended rate), 40, 60, 80, and 100...

We examined fine-root (< 2.0 mm diameter) respiration throughout one growing season in four northern hardwood stands dominated by sugar maple (Acer saccharum Marsh.), located along soil temperature and nitrogen (N) availability gradients. In each stand, we fertilized three 50 x 50 m plots with 30 kg NO(3) (-)-N ha(-1) year(-1) and an additional three plots received no N and served as controls. ...

Mishra G, Kumar N, Giri K, Pandey S, Kumar R. 2014. Effect of fungicides and bioagents on number of microorganisms in soil and yield of soybean (Glycine max). Nusantara Bioscience 6: 45-48. In field experiments, the effect of selected fungicides and bioagents on number of soil microorganisms and yield of soybean (Glycine max L. Merill) was investigated. The results showed that some of the crop ...

This research was conducted to evaluate the effect of soil application of nitrogen (N) and iron (Fe) fertilizers on morphological traits and shoot mineral contents of bread wheat via factorial arrangement based on randomized complete block design with four replications. The factors included three level of nitrogen (100, 200 and 400 mg N kg-1 dry soil applied) as Ca(NO3)2 and three rate of Iron ...

Nitrogen fertilizer application for corn (Zea mays L.) based on available N of soil can decrease the need to N fertilizer and, consequently, reduce the risk of environmental pollution, especially that of groundwater and drinking water. The objectives of this study were i) determining soil N03-N critical level at 4 to 6 leaf stage, ii) to study soil nitrate distribution, iii) determining N rat...

The effects of various organic manure [farm yield manure (FYM), sewage sludge and poultry manure] application on adsorption-desorption of three carbamate pesticides [oxamyl(I);S-Ethyl-Nmethylcarbamoyl)oxy]thioacetimidate (II) and N-Phenyl (ethyl carbamoyl) propyl carbamate (III) on six soil samples of Aligarh district was studied. Addition of organic manure increased soil organic carbon content...
