How Sensitive are Agricultural Production Systems Models to Crop Management Parameters? Why is it difficult to Quantify Farm Management?

How sensitive is the APSIM model to soil and crop management rules in the northern grainbelt of Australia?

The Decision-Maker has an Important, but Often Neglected, Role in Model Use.

Although a high proportion of papers on simulation and modelling appear aimed at decision-makers, these decision-makers are rarely identified or discussed.

On an alternative method for estimating the value of the Southern Oscillation Index (SOI), including case studies of selecting rates of N fertiliser and wheat varieties in the northern grainbelt.

Studies have identified optimal management options for each of the SOI phases, but in doing so may have overestimated the value of phase-based management through a lack of data for independent evaluation.

Opportunity Cropping - Benefits and Downsides

The question is how to achieve healthy crops and soils so that at the end of the day there is good farm profit.

Plant-available soil water and sub-soil constraints in the St George region.

A good crop depends on a supply of soil moisture and healthy roots. This paper looks at the maximum water storage of a soil that is useable by plants; its PAWC (plant available water capacity).
