Utilization of nitrogen in legume-based mobile green manures stored as compost or silage [PDF]

open access: yes, 2013
The utilization of nitrogen (N) in green manure leys can be improved by harvesting, storage and spreading of the plant material as manure in other crops. By green manure storage as silage, storage losses of N are lower than by composting.

Impact of nitrogen fertilizers on the natural weathering-erosion processes and fluvial transport in the Garonne basin [PDF]

open access: yes, 2000
Knowledge of the impact of N-fertilizers on the weathering-erosion processes of soils in intensively cultivated regions is of prime importance. Nitrification of NH4− fertilizers produces HNO3 in the basin of the Garonne river, enhancing soil degradation.

Demand for Nitrogenous Fertilizers and Fertilizer Price Policy in Pakistan [PDF]

open access: yesThe Pakistan Development Review, 1976
One of the major constraints to an increase in Pakistan's agricultural production is low fertilizer input. Despite spectacular growth of fertilizer con¬sumption during the '60s the rate of fertilizer application in Pakistan remains below the optimal rate [8, pp.77-90] and far below the rates in advanced countries [15, p. 24].
