Nitrogen Budgets and Soil Nitrogen Stocks of Organic and Conventional Cropping Systems: Trade-Off between Efficiency and Sustainability of Nitrogen Use [PDF]
Organic and conventional cropping systems differ in the nature and amounts of nitrogen (N) inputs, which may affect efficiency and sustainability of N use.

Beta-Beams: present design and expected performances
We give the present status of the beta-beam study, which aims at producing intense nue and antinue beams from the decay of relativistic radioactive io ns. The emphasis is put on recent technical progress and new ideas.

Nitrogen deficiency impacts on leaf cell and tissue structure with consequences for senescence associated processes in Brassica napus [PDF]
International audienceImprovement of nutrient use efficiency is a major goal for several crop plants, especially Brassica napus. Indeed, the low nitrogen use efficiency (NUE) in this crop results in negative economic and ecological consequences.

In maize, the bHLH transcription factor ZmbHLH118 directly binds to the promoter of ZmCLCa and inhibits its expression. Tonoplast‐localized ZmCLCa mediates NO3− influx into the vacuole to regulate intracellular NO3− homeostasis, modulating nitrate uptake and metabolism, plant growth, and grain yield.

Stickstoffbilanzen in biologischen und konventionellen Anbausystemen Das Effizienz-Nachhaltigkeits-Dilemma [PDF]
N-balances over 35 years from the DOK trial are presented and combined with Nstock changes in DOK treatments on different fertilisation levels. Results strongly indicate an N efficiency-sustainability dilemma: DOK treatments with a high nitrogen use ...

Dietary options to reduce the environmental impact of milk production [PDF]
A range of options was explored to test the hypothesis that diets for dairy cows could be formulated to reduce the carbon footprint (CFP) of feed, increase efficiency of conversion of potentially human-edible feed into milk, increase nitrogen use ...

Sugarcane phosphorus (P) availability is limited in tropical soils, requiring strategies to improve fertilizer efficiency. This study evaluated Bacillus velezensis UFV 3918 (Bv) in combination with an organomineral fertilizer (OF) at reduced monoammonium phosphate (MAP) doses. It showed that Bv + OF + 1/3 MAP achieved soil and plant P levels comparable

An organic vegetable crop rotation aimed at self-sufficiency in nitrogen [PDF]
The paper describes the organic vegetable crop rotation. The ideas behind the design of the crop rotation, the use of green manures and catch crops, and how information on crop root growth has been used to try to design a crop rotation with a high NUE ...

Optimal timing and rate of nitrogen fertilizer use: An integrated network technology approach
Abstract Both the rate and timing of crop fertilizer application play an important role in agricultural productivity. However, inefficient fertilizer use can significantly increase production costs, water pollution, and greenhouse gas emissions. To capture both the spatial heterogeneity and dynamic nature of this problem, we develop a multi‐stage ...

How Plants May Maintain Protein Homeostasis Under Rising Atmospheric CO2
ABSTRACT Vascular plants may employ several physiological mechanisms to stabilize their protein contents as atmospheric CO2 concentrations change over a day, year, decade, or century. One mechanism is that plants may rely more on soil ammonium as their nitrogen source when CO2 increases.
