Weather update: Most of the area is under hot and dry conditions. Spotty thunderstorms have resulted in variable rain ranging from no rain to 5 inches at Stoney Point (Essex). About 1/3 of normal total crop heat units (chu) will be accumulated by end of June. Considering cold temperatures to start the season, current chu are within a few days…
Christine Brown May 27, 2020 245 Comments Off on Phosphorus Loss Assessment using PLATO – AgriSuite’s newest calculatorIntroducing….to your mobile device or computer, the newest in a series of on-line calculators. The phosphorus loss assessment tool for Ontario, nicknamed PLATO, will help determine the risk of phosphorus (P) loss from nutrient applications at a field scale.PLATO takes both field characteristics, such as erosion risk and soil test level, as well as P application practices into account, and…
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…
Introducing….to your mobile device or computer, the first of several on-line AgriSuite calculators that will help with agronomic and environmental land use decisions. The nutrient management software (commonly known as AgriSuite, which includes NMAN and MSTOR) has been available to Ontario Farmers for many years. Although popular, it is perceived to be mainly a regulatory tool and perceived to be…
In much of Europe there have been restrictions to applying manure only during the growing season. There the technology has been perfected over time to meet those needs. Wouldn’t it be fitting to bring the technology to Ontario without the same application restrictions? I asked a few custom applicators what was holding them back from utilizing the European technology in…
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…
OMAFRA Field Crop Team August 22, 2019 1393 Comments Off on Ontario Field Crop Report – Week of August 19, 2019Soil Fertility Benefits of Wheat in Rotation Winter wheat harvest is now complete and before long the 2020 winter wheat crop will be seeded across the province (Figure 1). Yields have been better than expected for many. September planted wheat ranges from 100-130 bushels per acre, early October wheat ranges from 80-100 bu/ac and late October planted wheat yielded from 30…
Summary The Pre Sidedress Nitrogen Test (PSNT) soil samples were collected from 66 different sites across the province between June 17th and 19th, 2019 The average PSNT value was 8.3 ppm, which is below the long-term average of 12 ppm Consider corn stage and yield expectation along with PSNT values when determining nitrogen rate requirements in 2019. Below normal soil…
OMAFRA Field Crop Team June 6, 2019 1428 Comments Off on Ontario Field Crop Report – Week of June 3rd, 2019Corn Progress was made over the last week in areas with lighter textured soils. Those areas now have upwards of 80% of their intended corn acres planted. However, regions with heavier textured soils such as Lambton, Essex, Niagara and Middlesex have 30% of their corn acres planted. Overall, ~60% of the intended corn acres are planted in the province. With…
OMAFRA Field Crop Team May 23, 2019 2659 Comments Off on Ontario Field Crop Report – Week of May 23rd, 2019Weather patterns have been variable, leading to regional differences in progress on planting and crop growth. Soils continue to remain unfit for field operations in large parts of the province, especially in much of the southwest and parts of eastern Ontario (figure 1). A few pockets have had windows of opportunity to catch up on cultivation, fertilizer spreading, and planting….
Christine Brown May 9, 2019 1844 Comments Off on Consider Planting Corn First and Spreading Manure LaterTimely planting of corn followed by in-crop application up to V-4 leaf stage of corn can increase yield, reduce compaction, and increase nutrient use efficiency Are you envious of your crop neighbours that don’t have to worry about manure application on top of all the other spring work? Yes, spring 2019 has had a slow start, but rushing onto unfit…
Did you know that OMAFRA has a handbook that’s all about nutrients and soil fertility? It’s called the Soil Fertility Handbook and was first published in 1998. The book covers topics such as soil testing, soil pH and lime and fertilizer application. There’s a chapter on organic nutrient sources, like manure, biosolids and cover crops, as well as tips for…
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…
Jake Munroe June 22, 2018 2484 Comments Off on Ontario Field Crop Report, June 21, 2018: Sulphur response in Ontario’s field cropsSulphur (S) had been a neglected nutrient in Ontario for many years. For decades, in much of Ontario, sulphur came in significant quantities from the sky – deposited from emissions from industrial activity. Even before that, impurities in fertilizers and more widespread application of manure helped ensure a regular addition of sulphur to our soils. In recent years things have…
Correcting soil pH problems is one of the first steps in good soil management. If you have soil sampled recently and found that pH is low, you should act on it. Soil pH affects the availability of a wide range of nutrients in soil; if it is too low or too high, nutrients are less available to crops. If pH…
