management strategies to increase nitrogen use efficiency (nue) in agriculture

use of nitrogen fertilizers has contributed much to the remarkable increase in food production that has occurred during the past 50 years. however, environmental and economic challenges due to nitrogen application in agricultural have increased regard to nitrogen use efficiency (nue). studies conducted around the world shows that only half of nitrogen fertilizer inputs is taken up by crops. unf...

Stoichiometry of Consumer-driven Nutrient Recycling

How does consumer physiology and life history respond to them? And (3) What are their consequences for ecological processes in ecosystems? Elemental imbalances are defi ned by a mismatch between the elemental demands of a consumer and those provided by its resources. For example, carbon-tophosphorus (C:P) ratios in the suspended organic matter in lakes (i.e., algae, bacteria, and detritus) can ...

Maximizing root/rhizosphere efficiency to improve crop productivity and nutrient use efficiency in intensive agriculture of China.

Root and rhizosphere research has been conducted for many decades, but the underlying strategy of root/rhizosphere processes and management in intensive cropping systems remain largely to be determined. Improved grain production to meet the food demand of an increasing population has been highly dependent on chemical fertilizer input based on the traditionally assumed notion of 'high input, hig...

Nutrient Use Efficiency in Plants

Invariably, many agricultural soils of the world are deficient in one or more of the essential nutrients needed to support healthy plants. Acidity, alkalinity, salinity, anthropogenic processes, nature of farming, and erosion can lead to soil degradation. Additions of fertilizers and/or amendments are essential for a proper nutrient supply and maximum yields. Estimates of overall efficiency of ...

Predator-Driven Nutrient Recycling in California Stream Ecosystems

Nutrient recycling by consumers in streams can influence ecosystem nutrient availability and the assemblage and growth of photoautotrophs. Stream fishes can play a large role in nutrient recycling, but contributions by other vertebrates to overall recycling rates remain poorly studied. In tributaries of the Pacific Northwest, coastal giant salamanders (Dicamptodon tenebrosus) occur at high dens...
