Chen, W., McCaughey, W. P., Grant, C. A. and Bailey, L. D. 2001. Pasture type and fertilization effects on soil chemical properties and nutrient redistribution. Can. J. Soil Sci. 81: 395–404. Soil samples were collected from beef pastures varying in species composition and fertilizer inputs after being grazed by cow-calf pairs for 4 yr (1995–1998) near Brandon, Manitoba. The objective of this e...
Fertilization has been shown to affect interactions between root hemiparasitic plants and their host plants, alleviating damage to the hosts by parasitism. However, as a majority of studies were conducted in pot cultivation, the influence of fertilizer application on root hemiparasites and the surrounding plant community in field conditions as well as relevant mechanisms remain unclear. We mani...
Synthetic nitrogen fertilizers can contribute to environmental hazards. Moreover, their manufacturing is an energy-intensive process which causes greenhouse gas emissions, lead climate change. Therefore, it should evaluate the possibility use organic sources such as Azolla a partial substitute for synthetic in cultivation, this may reduce cost of fertilizer inputs, and promote sustainable agric...
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 ...
