Crop establishment - by computer

Abstract

<p>PLANTING can be a complicated operation with numerous decisions to make and many factors determining the success of the crop establishment. Establishment is a result of correct seed placement within well-formed beds allowing optimal seed-soil contact, sufficient but not excessive temperatures and moisture levels, vigourous seed and the absence of biotic threats (e.g. disease and insects) and physical barriers (e.g. surface crusting). It is unrealistic to expect perfect sowing conditions.</p> <p>The range of contributing factors needs to be balanced to ensure success. But have you ever wondered about the relative influence of each of these factors? We did, and we turned to a computer to help us assess this and challenge our beliefs.</p>
