Nitrogen fixation and accumulation in sugarcane under nitrogen supply

Research on Crops, 2014
In order to investigate nitrogen fixation and accumulation in sugarcane under nitrogen supply, a barrel gravel culture was conducted in Guangxi province, the southwest China in 2012. The sugarcane varieties B 8 and ROC 22 were employed as the plant materials, which were inoculated either with or without endogenous nitrogen fixation bacteria at two ...

Nitrogen Accumulation in Soybean Following Defoliation

Journal of Plant Nutrition, 2009
ABSTRACT 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, 1983
AbstractImproved 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

Mineralisation of newly accumulated nitrogen

2001
Since the 1950s, large amounts of nutrients (N, P and K) have been accumulated in German arable soils due to a surplus in the balance between the amounts of nutrients applied and those removed in crop harvest. In western Germany (the former FRG), a significant part (about 30–100 kg N ha−1 yr−1) of the surplus N (more than 100 kg N ha−1 yr−1 has been ...

Soil Nitrogen Accumulation Under Black Locust

Soil Science Society of America Journal, 1958
Abstract Soil nitrogen accumulation beneath stands of black locust, a leguminous tree, was studied at four locations in Tompkins County, N. Y. Adjacent areas identical in prior treatment served as controls. Significant increases were found under three 16‐ to 20‐year‐old plantations but not under a 5‐ to 10‐year stand.

Modeling plant nitrogen uptake and grain nitrogen accumulation in wheat

Field Crops Research, 2006
Grain nitrogen (N) concentration is one of the main quality parameters of wheat grains. Since few reports have quantified the processes of N accumulation in both grain and vegetative parts in wheat (Triticum aestivum L.), this study was undertaken to develop a dynamic model for simulating plant N uptake and grain N accumulation in wheat by focusing on ...

Pattern of cyanophycin accumulation in nitrogen-fixing and non-nitrogen-fixing cyanobacteria

Archives of Microbiology, 2001
The temporal and spatial accumulation of cyanophycin was studied in two unicellular strains of cyanobacteria, the diazotrophic Cyanothece sp. strain ATCC 51142 and the non-diazotrophic Synechocystis sp. strain PCC 6803. Biochemistry and electron microscopy were used to monitor the dynamics of cyanophycin accumulation under nitrogen-sufficient and ...
