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…

To plant green or to plant brown? Rye cover crop termination timing before soybeans (summary of 2017-2020 data)

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…

Soil Health

Jake Munroe, Soil Management Specialist – Field Crops, OMAFRA We’ve all seen them. Hilltops. Whitecaps. High spots where the crop struggles year after year. Eroded knolls are common to Ontario agriculture and cost farmers in lost productivity each season. However, not all eroded knolls are alike. In this two-part series, we will explore knolls: how they’ve formed and how they…

Introducing PLATO, the Phosphorus Loss Assessment Tool for Ontario

Jake Munroe June 24, 2020 664 Comments Off

Soil Health

Keeping soil covered and minimizing erosion is a key principle of soil health. Maximizing the efficiency of crop nutrient uptake and minimizing losses are the foundation of 4R Nutrient Stewardship. When combined, these principles form the basis of a new online tool from OMAFRA called PLATO (Phosphorus Loss Assessment Tool for Ontario). PLATO is a calculator that you can use to estimate the risk of phosphorus loss on your farm. It’s part of the newly re-vamped AgriSuite and uses your specific soil, crop and nutrient application information to provide a risk rating and options to improve your score.

How Ontario farmers are minimizing erosion on their farms

Cover Crops

It’s the time of year when you can see the impact of erosion on farm fields across the province. Whether it’s subtle (Figure 1) or obvious (Figure 2), erosion affects soil by reducing fertility, decreasing organic matter and lowering productivity. With National Soil Conservation Week happening from April 19th to 25th, I wanted to highlight some strategies Ontario farmers are…

Soil Fertility

Have you ever looked up the official Ontario fertilizer or liming recommendations? They’re featured in “look-up” tables in OMAFRA production guides, such as our Agronomy Guide for Field Crops (Publication 811), and provide rates for phosphorus, potassium, magnesium, zinc and manganese, as well as lime, based on soil test values. A new way to access Ontario fertilizer and liming recommendations…

Diagnosing Nutrient Deficiencies

Jake Munroe September 23, 2019 2769 Comments Off

Soil Fertility

Nutrient deficiencies can seriously impact crop yield. Certain deficiencies are seen every year in Ontario field crops, such as nitrogen deficiency in corn and manganese deficiency in soybeans. Others are brought on or made worse by environmental conditions – for example, potassium deficiency in soybeans and boron deficiency in alfalfa (Figure 1) during dry spells. Knowing how to identify deficiencies…

Cover Crops

With fall now officially here, thoughts are turning to harvest. And with each acre harvested, there is potential for a cover crop to be seeded. At this point in the season, the main cover crop option left is cereal rye. Not to be confused with annual ryegrass, rye is a cereal that is competitive, winter hardy and, like winter wheat,…

Strip-Till at Canada’s Outdoor Farm Show 2018

Corn

Strip-tillage is not a new practice – it’s been used by some Ontario growers for almost two decades. It’s gaining traction across the province more recently, however, due to advances in equipment, GPS technology, and advantages in fertilizer placement. What is strip-tillage? Strip-till is a system that creates residue-free strips that the following crop is planted into. The strips typically…
