Partition of biomass and nitrogen in a potato crop under three nitrogen fertilization treatments
Siembra, 2020 Nitrogen nutrition considerably influences the process of growing and producing potato crops. The aim of this study was to determine the effects of nitrogen nutrition on the pattern of biomass and nitrogen partitioning during the growth of potato crop in

Biological Nitrogen Fixation and Nitrogen Accumulation in Peatlands
Frontiers in Earth Science, 2022 Peatlands cover about 3% of the Earth’s surface and are regarded as a vital carbon (C) pool and sink. The formation of peatland is supported by continuously supplied nitrogen (N) but the sources of this N remain unclear. Here, we first review N stocks and the rate they accumulate in peatlands, then we present the sources of N, especially through ...

Nitrogen Accumulation in Forests. Exposure Monitoring by Mosses [PDF]
The Scientific World JOURNAL, 2007 At present, there is still little information on nitrogen (N) accumulation in forests contrasting with the crucial importance of N in forest ecosystems. This work analyzes the N bioaccumulation in mosses from forested areas from Lower Saxony and North Rhine-Westphalia (two of 16 federal states of Germany), the Weser Ems Region (part of Lower Saxony ...

A secular increase in continental crust nitrogen during the Precambrian [PDF]
, 2017 Recent work indicates the presence of substantial geologic nitrogen reservoirs in the mantle and continental crust. Importantly, this geologic nitrogen has exchanged between the atmosphere and the solid Earth over time. Changes in atmospheric nitrogen (i.

Influence of Nitrogen Availability on Seed Nitrogen Accumulation in Pea
Crop Science, 1999 ABSTRACTThe final seed nitrogen concentration (the ratio of seed N and dry matter content) is highly variable in pea (Pisum sativum L.) and N remobilization during seed filling may limit yield by restricting the seed filling period. This study was conducted to determine how seed N accumulation is regulated in pea.
