Abstract Higher crop production normally demands higher nutrient application rates and consequently increased mineral nitrogen use. With food demand for 2030 estimated around 2800 mill. tonnes (t) yr−1, the corresponding mineral N consumption figure is 96 mill. t (78 mill. t yr−1 in 1995/1997). Global-level mineral N losses to the environment from mineral fertilizer use are currently 36 mill. t yr−1, worth USD 11 700 mill. and with adverse environmental impacts. However, innovative fertilizer…

Management Drives Differences in Nutrient Dynamics in Conventional and Organic Four-Year Crop Rotation Systems
TLDR
This study evaluated mineral N dynamics, yields, residue inputs, and change in soil organic C (SOC) and total N (TN) in strip-tilled, four-year crop rotations in conventional and organic cropping systems and indicated ORG management supported N availability by generating intrinsic N.
Nitrogen and Food Production: Proteins for Human Diets
TLDR
The future global use of N fertilizers can be moderated not just by better agronomic practices but also by higher feeding efficiencies and by gradual changes of prevailing diets, and it could be possible to supply adequate nutrition to the world's growing population without any massive increases of N inputs.
Evaluation of nitrogen cycling associated with agricultural production and environmental load in a mountain region, in Hokkaido, Japan
This study examined the nitrogen cycling associated with agricultural production and environmental load in central Hokkaido. The nitrogen (N) budget analysis model offers a new set of tools for…
Future carbon dioxide removal via biomass energy constrained by agricultural efficiency and dietary trends
We assess the quantitative potential for future land management to help rebalance the global carbon cycle by actively removing carbon dioxide (CO2) from the atmosphere with simultaneous bio-energy…
The Effects of Combined Application of Cattle Manure and NP Fertilizers on Yield and Nutrient Uptake of Potato in North-Eastern Ethiopia
TLDR
In conclusion, the results revealed that integrated application of chemical and organic fertilizers could be the best strategy to restore highly depleted soils and to enhance economical production of potato in Kobo district and similar agroecologies.
Substitution Effect of Pig Manure for Nitrogen Fertilizer on Nitrogen-Use Efficiency
Pot experiments using a 15N isotope technique were conducted to quantify the substitution effect of pig manure (PM) for chemical fertilizer (CF) nitrogen (N) on N-use efficiency. Treatments include a…
Reactive nitrogen in Indian agriculture : Inputs, use efficiency and leakages
TLDR
Among a host of upcoming technologies aimed at improving N management strategies, leaf colour charts, chlorophyll meters and optical sensors, which allow in-season estimation of N requirement of crops, are the most promising.
Piling up reactive nitrogen and declining nitrogen use efficiency in Pakistan: a challenge not challenged (1961–2013)
Excessive nitrogen (N) application and reduced nitrogen use efficiency (NUE) are the key reasons behind N notoriety worldwide, including in Pakistan. We estimated the changes in NUE of Pakistan by…

Factors regulating the contributions of fixed nitrogen by pasture and crop legumes to different farming systems of eastern Australia
TLDR
On-farm and experimental measures of the proportion (%Ndfa) and amounts of N2 fixed were undertaken for 158 pastures either based on annual legume species, or lucerne, or winter pulse crops over a 1200 km north-south transect of eastern Australia, providing new insights into differences in factors controlling N2 fixation in the main agricultural systems.
