Estimating nitrate leaching under a sugarcane crop using APSIM-SWIM

The Lower Burdekin Delta (LBD) is located on the dry-tropical coastal strip in North Queensland, Australia. The region is Australia’s largest sugar producing area with approximately 38,000 hectares of land under sugarcane. However, the LBD also borders the Great Barrier Reef World Heritage Area (GBRWHA). Thus industry, community, and federal, regulatory and environmental organisations are inter...

Controlling nitrate leaching in irrigated agriculture.

The impact of improved irrigation and nutrient practices on ground water quality was assessed at the Nebraska Management System Evaluation Area using ground water quality data collected from 16 depths at 31 strategically located multilevel samplers three times annually from 1991 to 1996. The site was sectioned into four 13.4-ha management fields: (i) a conventional furrow-irrigated corn (Zea ma...

Nitrate Leaching in Florida Urban Environments

3 Introduction Numerous counties within the State of Florida have proposed restrictions on the sale and application of fertilizer. Fertilizer nitrogen is a pollutant in Florida's shallow groundwater. Excessive nitrate-N in drinking water can cause low oxygen in infant's bloodstream (blue baby syndrome), spontaneous abortions, and non-Hodgkin's lymphoma. Average groundwater background nitrate co...

No-tillage and fertilization management on crop yields and nitrate leaching in North China Plain

A field experiment was performed from 2003 to 2008 to evaluate the effects of tillage system and nitrogen management regimes on crop yields and nitrate leaching from the fluvo-aquic soil with a winter wheat (Triticum aestivum L.)-maize (Zea mays L.) double-cropping system. The tillage systems consisted of conventional tillage (CT) and no-tillage (NT). Three nitrogen management regimes were incl...
