Site-Specific Nutrient Management: Implementation guidance for policymakers and investors

Stimulated fine root growth benefits maize nutrient uptake under optimized nitrogen management

Optimized nitrogen (N) management reduces total N application without sacrificing cropyield. However, the underlining mechanisms have not been well investigated, especially lackingthe evidence from roots. Here we performed a two-year field experiment with maize grownunder zero-N, conventional N and optimized N applications and examined grain yield, N,phosphorous (P) and potassium (K) uptake and...

Timber Mapping for Site-Specific Forest Management

The adoption of precision agriculture technologies and site-specific management has been limited in the forest industry. Geographic information systems (GIS) and remote sensed imagery have been used in forest management, but at a landscape scale, typically to prescribe and schedule treatments for a diverse collection of relatively large tracts. Individual stands have traditionally been treated ...

Flue gas desulfurization gypsum: implication for runoff and nutrient losses associated with broiler litter use on pastures on ultisols.

Gypsum has been shown to reduce runoff on soils prone to crust formation in the southeastern United States. Increased infiltration from gypsum applications could therefore help reduce runoff P and other nutrient losses from application of broiler litter (BL), a nutrient-rich fertilizer. In rainfall simulation experiments in June 2009 and May 2011, runoff and nutrient (N, P, Ca, Mg) losses in ru...
