The Coupled Effect of Precipitation and Fertilization on Nitrogen Loss Via Surface Runoff from Paddy Fields

Guan'gai paishui xuebao, 2023
【Objective】 Nitrogen loss from soils is a pervasive environmental issue facing agricultural production in many countries. In this paper, we studied the combined effect of rainfall and fertilization on nitrogen loss via surface runoff from paddy fields in

Nitrogen Fertilization. A Review of the Risks Associated with the Inefficiency of Its Use and Policy Responses

Sustainability, 2021
Nitrogen (N) is a key input to food production. Nearly half of N fertilizer input is not used by crops and is lost into the environment via emission of gases or by polluting water bodies.

Organic nitrogen fertilization benefits selected soil fauna in global agroecosystems

Biology and Fertility of Soils, 2022
Soil fauna plays an essential role in agricultural productivity as it mediates nutrient cycling and soil organic matter dynamics, alters soil physicochemical properties and supports plant growth.

The Response of Three Varieties of Wheat to Nitrogen Fertilization [PDF]

مجلة جامعة النجاح للأبحاث العلوم الطبيعية, 1998
The effects of different levels of nitrogen fertilization (0, 2, 4, 8 and 16 kg N / dunum) on the production of three wheat varieties (780, Lakeesh and Anbar) were studied. The experiment was conducted for two successive seasons 1994 and 1995.

Compensatory Effects Between CO2, Nitrogen Deposition, and Nitrogen Fertilization in Terrestrial Biosphere Models Without Nitrogen Compromise Projections of the Future Terrestrial Carbon Sink

Geophysical Research Letters, 2023
Although terrestrial biosphere models (TBMs) with and without nitrogen cycling successfully reproduce the historical terrestrial carbon sink, the influence of nitrogen cycling under interacting and intensifying global change drivers in the future is ...
