Agricultural Land: Nitrogen Balance

Di: Everly

Nitrogen (N) is the most important yield-limiting factor in agricultural systems, however, N application can lead to emissions and environmental problems such as global warming (N2O) and groundwater

Carbon and Nitrogen Cycling in Agroecosystems: An Overview

In other words, attaining proper nitrogen balance in agricultural land is one of the most critical factors for sustainable agriculture in terms of productivity and the environment.

| Calculation of Nitrogen farm balance without (light color) and with ...

We calculated Nitrogen (N) use efficiencies and N balances for different farm types using German Farm Accountancy Data Network. We found high variance in N performance

Background: Understanding the nitrogen (N) use efficiency and N input/output balance in the agricultural system is crucial for best management of N fertilisers in China.

Majority of the conversions of anthropogenic Nr are on land within soils and vegetation. Emissions of ammonia (NH 3) and nitrogen oxides (NOx) in the atmosphere lead to

  • Changes in Agricultural Nitrogen Balance of OECD Countries
  • Managing nitrogen to achieve sustainable food-energy-water
  • Gross nutrient balance in agricultural land

More densely populated countries with smaller agricultural land per capita (ranging from 0.03 to 0.47 ha capita -1) showed a higher N balance (228-80 kg ha -1), presumably due to higher N

Nitrogen is the main element of many fertilizers used in agricultural production. The agricultural N balance describes the difference between all N inputs and outputs in agricultural

Estimates for 2022 show that the UK nitrogen balance was a surplus of 79.1 kg/ha of managed agricultural land. This represented a decrease of 13.5 kg/ha (-14.5%) compared to

It remains uncertain whether one can achieve a balance between productivity and environmental sustainability in orchard systems by reducing nitrogen (N) fertilizer inputs and

According to FAO 3, more than 109 million tons of nitrogen fertilizers were used for agricultural and livestock production in 2017. The importance of using nitrogen fertilizers in

The nitrogen balance in a. Acknowledgments. This work was supported by the National Natural Science Foundation of China (Nos.: 51079048 and 40601050), the Ministry of

With this study we present a clear framework for the estimation of soil, land, and farm N-budgets and the quantification of two major indicators, namely the Nitrogen Use

In this study, the spatial variability of nitrogen (N) balances and potential nitrate leaching were determined in heterogeneous arable fields in southern Germany using digital

Nitrogen balance is increasingly used as an indicator of the environmental performance of agricultural sector in national, international, and global contexts. There are

Water and nitrogen fertilizer management are highly coupled, the synergistic effect of water-saving irrigation combined with appropriate nitrogen application on rice yield is mainly

In spite of the importance of N management in agricultural production, closing the full nitrogen balance remains a challenge, mainly due to the uncertainties in both fluxes of

The gross nitrogen balance lists the nitrogen inputs to agricultural soils and nitrogen outputs removed from the soil. The main indicator from the gross nitrogen balance is the gross nitrogen

It consists of the Gross Nitrogen Balance and the Gross Phosphorus Balance and is an indicator of the potential threat of surplus or deficit of two important soil and plant nutrients in agricultural

A complete understanding of the nexus between productivity and sustainability of agricultural production systems calls for a comprehensive assessment of the nitrogen budget

Australian Journal of Agricultural Research 32: 37–45. Article :1267–1272. McGill W B, Hunt H W, Woodmansee R G, Reuss J 0 (1981) Phoenix — a model of the dynamics of carbon and

The three main nutrients for plant growth are nitrogen (N), phosphorus (P), and potassium (K). Excess nutrient loads on cropland represent environmental risks such as nitrate

The predicting groundwater nitrate pollution risk, especially in terms of changes in fertilizing, has not been fully investigated so far. In particular, there is no comprehensive

More densely populated countries with smaller agricultural land per capita (ranging from 0.03 to 0.47 ha capita-1) showed a higher N balance (228-80 kg ha-1), presumably due to higher N

By employing panel Autoregressive Distributed Lag, we found that a 1% increase in organic farming areas is associated with a 0.054% decrease in nitrogen balance in the long run.

The vast areas of non-agricultural land and arid rangelands appear to be in neutral N balance and the relatively small area of intensive agriculture is in negative balance. There are regional N
