N input of fertilizer is the largest source of NANI, followed by atmospheric N deposition and N fixation.
Financial markets might potentially help to finance the input of fertilizer, seeds, water pumps and the rest that is urgently needed, but these markets are not (yet) to be found in the villages.
- Increasing input of fertilizers and pesticides cause soil erosion problem in that particular highland areas.
Soil used in the study was not used for cultivation in the past and had not received any anthropogenic input of fertilizers.
The previous green revolution involved significant inputs of fertilizer, pesticide, and irrigation--those are not going to be the solutions in the future.
For example, crops might be genetically modified to maximize biomass production and improve conversion rates, while minimizing inputs of fertilizer and water.
In addition, for many countries, sustaining high rates of agricultural production requires ever-increasing inputs of fertilizers and pesticides, as well as the constant development of new plant varieties.
More than the external industrial inputs of fertilizers, chemicals, pesticides, healthy soil management have been explained to be the key to high yield and sustainable production (Howard 1943 , 1947.
Since the rate of carbon sequestration can be doubled in soil with depleted organic carbon [40], conservation tillage practices can be effectively carried out in the irrigation districts 'Bajo Bravo', 'Bajo San Juan', and 'Las Lajas', where agriculture is highly mechanized, irrigated, and with high inputs of fertilizers, pesticides, and herbicides.

The introduction of semi-dwarf genes increased yield by conferring lodging resistance, which enabled greater input of nitrogen fertilizer.
