Crop Row Placement- 10 things to consider
IN THEORY, a seed row can be placed at any distance desired from the previous crop row with the right equipment. Conventional practice is to aim for sowing in the inter-row which is the maximum distance from the previous crop row in order to optimise the seeding operation for residue handling, herbicide incorporation and to reduce disease risk associated with stubble from previous crops.
Experiments in Western Australia have shown that the use of on-row sowing, or edge-row sowing as close as practical to the previous crop row without disturbing that row, can provide a pathway for water infiltration using the intact root system of the previous crop, with the effect of increasing crop establishment and biomass (Roper et al. 2015. Management options for waterrepellent soils in Australian dryland agriculture, Soil Research 53, 786-806).
