An integrated approach to acid soil management comprises a spatially variable liming strategy, the use of acid-tolerant species, efficient use of fertilizers, suitable crop rotations and crop diversification.
Potential supply shortages of phosphorus (P) rock reserves call for a more efficient use of P fertilizer and exploring new ways of recycling the nutrient within agro-ecosystems.
This, in itself, facilitated greater stocking rates and a 5 to 10% increase in milk output per hectare but, perhaps more importantly, it allowed a more efficient use of nitrogen fertilizer, further increasing milk output/land area by 20%.
For example, drones can survey agricultural lands and help producers make more efficient use of seeds, fertilizer and water.
Food production's contribution to greenhouse gases could be driven down further by more efficient use of cropland, fertilizer and irrigation and by measures that reduce food waste, they said.
Therefore, efficient use of artificial fertilizers should be given due attention.
Strengthening the sector depends upon the efficient use of organic fertilizers of animal origin for an optimal primary production in fish conventional systems (Goulding et al. 2008).
Mr. Dixon envisions Airware's technology being used by other parties to develop applications — one for farmers, say, that helps inspect crops for more efficient use of water and fertilizer.
Hence, P nutrition of soils is critical for the efficient use of inorganic N fertilizer in the area.
