Best management practices suggest that seed placed fertilizer, residue management and cover crops will help prevent soil phosphorus from reaching water courses. Manure application requires extra attention to prevent phosphorus losses, especially during winter and snow melt conditions.
Protecting watersources from manure would be a lot easier if the weather would cooperate. After a relatively good growing season, the conditions since September have been wetter than normal with only short windows between rain events to complete harvest and field work. A challenging corn harvest, combined with wet soils…
Snow plays a crucial role in maintaining healthy soils throughout the winter months.
The Food and Agriculture Organization of the United Nations estimates that around 45 million tons of phosphorus fertilizers will be used around the world in 2018. Much will be applied to soils that also received phosphorus fertilizers in past years.
Solonetzic soils have a subsurface soil horizon layer characterized by a higher level of sodium (Na) and often an accumulation of clay. This hardpan layer makes soil management and crop production a challenge. These soils occur most commonly in Alberta and Saskatchewan (Figures 1 and 2), and less commonly in…
The research agronomy team from A&L Canada Laboratories based in London, Ont. developed and launched VitTellus Soil Health, a yield-correlated soil health test. The test and recommendation package aims to help farmers and crop consultants make more informed decisions on the application of nutrients and soil management.
Producers who haven’t had a soil test in the last three years could be over-applying, under-applying or unnecessarily applying nutrients. In this week’s crop report, OMAFRA staff provide answers to common soil questions and cover the basics of soil sampling and soil test interpretation. | READ MORE
Over the past 20 years, many western Canadian farmers have shifted to no-till or minimum tillage. During this time, the amount of summer-fallowed land has declined to the point that over 90 per cent of cultivated land is continuously cropped each year.
According to David Lobb, best management practices for soil health might actually have a negative impact on water quality, because any extra phosphorus stored in residue on the soil surface can potentially move into waterways in runoff events.
Fertilizers and manure are often applied in the fall to help crops get off to a good start the following spring. There’s some new research, however, that indicates the practice may not be as productive as farmers think.
Research is building on the many benefits of cover crops, from their ability to help boost yields in subsequent crops to improved soil structure and reduced erosion.
Add just enough fertilizer, and crops thrive. Add too much, and you may end up with contaminated surface and groundwater.
Understanding soil nutrient dynamics in a field is about more than numbers, and a new approach, using a spreadsheet with built-in formulas and a new bioassay, is intended to address some of the problems with conventional soil test numbers.
The Soil Conservation Council of Canada (SCCC), along with Canadian senator Rob Black, University of Guelph's Dean Rene Van Acker, and John Poel from Heartland Soil and Crop, will be planting cotton underwear in the ground to reignite the importance of soils and soil health on July 23, 2018 in Elora,…
In the 2015 International Year of Soils, two key global soil resources were published by the United Nations’ Food and Agriculture Organization's (FAO) Intergovernmental Technical Panel on Soils (ITPS). The first Global Soil Partnership (GSP) effort was a revised World Soil Charter and the second was the first ever State…
