Nitrogen Accumulation in Successions
1974Nitrogen in ecosystems has been determined as a function of time of plant succession in the entire ecosystem, in its biomass, and in its soil alone.

Nitrogen Accumulation in Soybean Following Defoliation
Journal of Plant Nutrition, 2009ABSTRACT The effects of defoliation on soybean [Glycine max (L.) Merr.] growth and yield have been well studied, but relatively little is known about its nitrogen (N) accumulation after defoliation. An experiment was conducted to examine soybean recovery and N accumulation following defoliation. The indeterminate cultivar (‘Tousan 69’) was planted in a

Nitrogen Accumulation Rates of Irrigated Maize
Agronomy Journal, 1983AbstractImproved fertilizer nitrogen (N) use efficiency in irrigated maize (Zea mays L.) often results from delaying application of moderate N rates until the crop is rapidly growing. The objective of this experiment was to determine how N application time, N rate, and planting date influenced the pattern of N and fertilizer−derived N (FN) accumulation

Canadian Journal of Plant Science, 1995
An understanding the relationships between N-fertilization rate, crop-N recovery, residual inorganic N in soil and crop yield can assist in making N fertilizer recommendations which balance crop value and environmental risk. Nitrogen was applied to three plantings of broccoli at 0, 125, 250, 375, 500 and 625 kg N ha−1 as a broadcast application of ...

Relationships Between Soil Nitrogen Availability Indices, Yield, and Nitrogen Accumulation of Wheat
Soil Science Society of America Journal, 2002The success of variable rate N fertilizer application rests on our ability to predict the contribution of soil N to growing crops. We assessed relationships between soil N availability indices (SNAIs), yield, and total N accumulation of wheat ( Triticum aestivum L.) grown in a typical glacial

Nitrogen (N) accumulation and its partition in a canola (Brassica napus L. ssp. oleifera var. annua) crop growing under different N availabilities were evaluated. Spring canola (cultivar Printol) plants were grown with 0, 30, 60, 90, 120, or 150 kg N ha− 1 applied at sowing.

Seasonal accumulation and partitioning of nitrogen by lentil
Plant and Soil, 1994Although wheat (Triticum aestivum L.) is the dominant crop of the semi-arid plains of Canada and the western United States, lentil (Lens culinaris Medik.) has become an important alternative crop. Sources and seasonal accumulation of N must be understood in order to identify parameters that can lead to increased N2-fixing activity and yield. Inoculated

Monitoring nitrogen accumulation in mosses in central European forests
Environmental Pollution, 2008In order to assess whether nitrogen (N) loads in mosses reflect different land uses, 143 sites in North Rhine-Westphalia, the Weser-Ems Region and the Euro Region Nissa were sampled between 2000 and 2005. The data were analysed statistically with available surface information on land use and forest conditions.

ABSTRACT Conventional wisdom views winter as ecologically dormant, overlooking a critical phase in the annual nitrogen (N) cycle. This review establishes the ‘winter N pump’ as a key conceptual framework, reframing the cold season as an active control point for ecosystem N budgets.
