Crops:The Lynch File - How many soy seeds per acre do you need to plant?


For years, there has been open disagreement on what seeding rate you should use for soys. There has been some consensus that seven-inch rows require more seeds per acre than 14- or 15-inch rows. But after that there is little general agreement. Some of us have been advocating lower populations than others. All of us are using our own experiences to come to the best seeding rate. The seeding rate being put forward by the Ontario Ministry of Agriculture, Food and Rural Affairs this past couple of years is lower than what was once recommended. This is due to the hard work of Horst Bohner who has spent a lot of time doing on-farm trials on soybean seeding rates.
