The distribution of agricultural land in south and central Manitoba is easily mapped using small-scale images that provide an overview. At a larger scale the patterns produced by various stages of harvesting provide some of the most distinctive images of southern Manitoba. Old photos record obsolete techniques, and newer images demonstrate techniques used to cope with high evaporation rates and limited precipitation (field shelterbelts and irrigation). As with natural vegetation, so too with crops, colour infrared photos are useful in detecting crop types and diseases.
14.8: Harvesting Patterns in Southern Manitoba
This photograph taken at harvest time shows the usefulness of tone and pattern in detecting land use and the stage of the harvest. Several fields have been left fallow or have had the crop removed from them 1. These show the characteristic mottled appearance resulting from light-toned crests that have had dark-coloured soil constituents removed by rain splash and wind erosion. In several other fields the grain crop has been swathed, that is, cut and left in rows that exhibit the characteristic cutting pattern 2 with variations due to field shape 3. Other fields have been combined; the swath has been picked up and thrashed to remove the grain with straw being fed out from the back of the combine. The resulting rows of straw are wider 4 and generally lighter-toned 5 than swaths. In one field 6 the swath has been partly combined; in fact the location of the combine can be seen 7.
This is an area of ground moraine topography with a hummocky surface and several small sloughs 8. A small intermittent stream with wooded banks 9 drains to the south.
Shown here are four full sections with gravel roads along most of the section lines 10. In two cases the division into quarter section is clear 11. The area is sparsely settled with only five farmsteads 12 in an area of just over four square miles. A railway line 13 cuts across the northeast corner.
