In this article, we will take a look at using a roller crimper for organic no-till soybean production and the results of on-farm trials in Ontario. Why organic no-till? Organic soybean production relies on a significant amount of tillage. When done well, yields can rival conventional production. There are drawbacks, however, including a high labour demand in the spring and…

Cover Crops

Jake Munroe, Mike Cowbrough and Sebastian Belliard (OMAFRA) Cereal rye (Secale cereal) has several strengths as a cover crop option. It’s relatively inexpensive and easy to kill. Rye improves soil structure, builds organic matter and helps protect against water and wind erosion. It can suppress weeds as discussed here (see Figure 1). It’s also very winter hardy and often the…

White Mould in Soybeans Can be Controlled

Soybean

This article was written by Horst Bohner, OMAFRA Soybean Specialist, and Paul Sullivan, Sullivan Agro Inc. White mould can be one of the most devastating soybean diseases growers face. The extent of yield loss is largely dependent on the inoculum “load” of a field and the right weather occurring during soybean flowering. If the disease was previously a problem in…

Applying Manure to Soybeans as an Alternative to Corn

Soil Fertility

  Corn is the perfect crop for receiving the nutrients from manure. Liquid manure applied to meet two-thirds of the nitrogen needs will generally provide a good balance of the macro and micro nutrients needed for a highly productive corn crop. Using commercial starter and nitrogen for the balance of the crop’s needs ensures nutrients are available early in the…

Reducing Soybean Lodging

Soybean

  Soybean lodging (plants that fall over) can seriously impact yield. Fortunately, it’s often only small portions of a field that lodge. In rare cases whole fields will go down, which devastates yield potential. Light penetration into the canopy during key growth stages will be impeded by lodging, reducing a plant’s ability to produce seed. Lodging that occurs from R3…

In the video series below, we provide an overview of roller crimping rye for organic no-till soybean production. We give an overview of the system and profile the experiences of two Ontario farmers. To learn about the on-farm trial results, click here. A detailed project report can be found here. While there are many benefits of organic agriculture, one of…

Pre-Harvest Herbicide Timing in Soybeans

Soybean

A pre-harvest herbicide treatment can make harvest more efficient when there are an unacceptable number of weeds in a soybean crop. Both conventional and glyphosate tolerant fields that are weedy can benefit from a pre-harvest herbicide. Drier plant matter will pass more easily through the combine, lowering seed losses and reducing seed staining…

Bean Leaf Beetle Pod Feeding Activity

Baute Bug Blog

Reports have been coming in about pod feeding from bean leaf beetle (BLB) in IP, food grade and seed soybeans. Pod damage on crush beans typically does not warrant control. Foliar feeding (defoliation) is rarely the concern this time of year. But BLB can feed on the surface of the pod which exposes the seed inside to pod diseases that…

This week we would like to discuss tar spot in corn as well as soybean cyst nematode and sudden death syndrome in soybean. Tar Spot in Corn There is a lot of discussion and questions surrounding tar spot this year in Ontario. Tar spot is a new corn disease in the US midwest and since its initial confirmation in northern…

The 1st Trifoliate is the Best Time to Roll Soybeans

Horst BohnerHorst Bohner June 3, 2020 1218 Comments Off on The 1st Trifoliate is the Best Time to Roll Soybeans
Soybean

Land rolling helps conserve moisture, levels the soil, and pushes small rocks into the ground. Some producers roll immediately after planting, while others wait until the soybeans have emerged. Rolling immediately after planting provides improved seed-to-soil contact and reduces the likelihood of plant injury. But, it also increases the chance of soil crusting, which hinders emergence. Some growers choose to…

Soybean Replant Considerations

Horst BohnerHorst Bohner May 29, 2020 1007 1 Comment
Soybean

Soybeans are prone to poor plant establishment because the seedling must pull the cotyledon seed leaves through the ground to emerge. Plant stand reductions are rarely uniform, which makes the decision to replant difficult. Do not assess a poor soybean stand too quickly, since more seedlings may still emerge. In 2020 we have seen soybeans emerge 40 days after planting….

Is it Too Cold to Plant Soybeans?

Horst BohnerHorst Bohner May 6, 2020 2355 3 Comments
Soybean

Prolonged cold weather this spring has led some producers to wonder if soybean planting should be delayed. Over the next few days weather forecasters are even predicting a “polar vortex” with possible daytime highs of 3°C and nighttime temperatures of minus 3. Does this mean soybean planting should be delayed until things warm up? There is an old adage that…

While the growing season started early in many regions, cooler temperatures over the last week have slowed progress. Manure applications continue where soil conditions are fit. Cereals Winter wheat planted prior to mid-October continues to look good. However, some late planted fields have holes due to winterkill or excess water. Growers with a market for mixed feed grain are choosing…
