Nitrogen Fixation and Nitrogen Fertilization of Soybeans

Isotopes in Environmental and Health Studies, 1996
Abstract In pot experiments with (15)N labelled soil and mineral (15)N, the influence of Bradyrhizobium (Rhizobium japonicum) inoculation and N fertilization on the symbiotic N(2) fixation and yield of soybeans [Glycine max (L.) Merill., cv. 'Fiskeby V'] was investigated.

Influence of nitrogen fertilization on broccoli yield, nitrogen accumulation and apparent fertilizer-nitrogen recovery

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 ...

Uptake of fertilizer nitrogen and soil nitrogen by rice using15N-labelled nitrogen fertilizer

Plant and Soil, 1980
Data from five field experiments using labelled nitrogen fertilizer were used to determine the relative effects of soil nitrogen and fertilizer nitrogen on rice yield. Yield of grain was closely correlated with total aboveground nitrogen uptake (soil+fertilizer), less closely correlated with soil nitrogen uptake and not significantly correlated with ...

Lignite-Based Nitrogenous Fertilizers

Energy Sources, 1983
A sample of lignite from Elbistan was oxidized by nitric acid in two stages, using relatively dilute acid in the first stage and concentrated acid in the second stage, and then the oxidized product was ammoniated so that a coal-based fertilizer could be produced. The experiments of all the stages were designed by a 1/2 X full factorial design.

Fertilizer nitrogen isotope signatures

Isotopes in Environmental and Health Studies, 2007
There has been considerable recent interest in the potential application of nitrogen isotope analysis in discriminating between organically and conventionally grown crops. A prerequisite of this approach is that there is a difference in the nitrogen isotope compositions of the fertilizers used in organic and conventional agriculture.

Immobilization of fertilizer nitrogen and consequences for nitrogen fertilization of cereals

2001
From field trials with winter cereals it is known that about half of the applied fertiliser N (N) is not recovered in crops nor in soil mineral N (Nmin). In some experiments it has been shown that most of this non-recovered N was immobilized by soil microorganisms, which reduced fertiliser N availability for the crops. In field trials with winter wheat
