Management practices that reduce greenhouse gas emissions from farms or increase on-farm carbon storage can contribute to climate change mitigation. Farmers, however, are only likely to adopt new management practices if they contribute to farm profitability. We use the Agricultural Production Systems sIMulator (APSIM) to simulate how different cropping practices contribute to greenhouse gas aba...

Cereal-legume intercropping can increase yields, reduce fertilizer input and improve soil quality compared with pure culture. Designing systems requires the integration of plant species trait selection choice crop configuration management. Crop growth models facilitate understanding prediction interactions between traits, However, currently no existing model has been calibrated tested for cerea...

Nitrogen (N) dynamics in ley-arable cropping systems require better understanding order to assess the potential of such contribute improved productivity and reduced nutrient losses crop production. Large inputs organic matter after termination ley phase result increased mineralization N availability subsequent crops. The description quantification this residual effect remains a major scientific...

In order to estimate the adaptability of Agricultural Production Systems Simulator (APSIM)-Maize model under special climate environment in tropic, 10 field experiments were conducted at different seasons three sites (Longchuan, Mangshi and Ruili) tropic Yunnan Province, China. The parameters APSIM calibrated its was validated. results showed that days from sowing flowering maturity predicted a...

Agriculture of the inland arid region in Xinjiang depends on irrigation, which forms oasis of Northwest China. The production and water use of wheat, a dominant crop there, is significantly affected by undergoing climate variability and change. The objective of this study is to quantify inter-annual variability of wheat yield and water use from 1955 to 2006. The farming systems model APSIM (Agr...

Studies evaluating the complexity of models, which are suitable to simulate grass growth at regional scales in intensive grassland production systems scarce. Therefore, two different models (GrasProg1.0 and APSIM) with input requirements were compared against long-term observations from variety trials perennial ryegrass (Lolium perenne) Germany Denmark. The trial sites covered a large range env...

The environment in which crops will be grown in the future will change. Temperatures and CO2 concentrations [CO2] will increase. Also a decline in winter rainfall of up to 30% in 2070 is predicted for south-west Australia. Effects of climate change on cropping systems were simulated with the Agricultural Production Systems Simulator (APSIM-Nwheat) using transformed historic weather data. Fifty ...

The major wheat production region of China the North China Plain (NCP) is seriously affected by air pollution. In this study, yield of winter wheat (Triticum aestivum L.) was analyzed with respect to the potential impact of air pollution index under conditions of optimal crop management in the NCP from 2001 to 2012. Results showed that air pollution was especially serious at the early phase of ...
