Fertility and Nutrients
Soil phosphorus (P) occurs in many inorganic and organic forms. Only a very small portion of inorganic soil P is available for plant uptake, with none of the organic forms taken up directly by plant roots. Phosphorus is the most challenging of all the plant nutrients to understand, as it…
Nitrogen can present a dilemma for farmers and land managers.On one hand, it is an essential nutrient for crops.However, excess nitrogen in fertilizers can enter groundwater and pollute aquatic systems. This nitrogen, usually in the form of nitrate, can cause algal blooms. Microbes that decompose these algae can ultimately remove…
Sulphur fertilizer’s form, such as elemental sulphur, gypsum or ammonium sulphate, affects its behaviour in the soil and its availability to the plant. The best form depends on the situation. Factors such as soil and crop type, weather conditions and timing all come into play. A Saskatchewan study has evaluated…
Keeping a grass forage stand productive is difficult enough, but add in severely saline soils and the challenges are amplified. A three-year research trial at Agriculture and Agri-Food Canada (AAFC) Swift Current Research and Development Centre in Saskatchewan is looking at how a one-time application of nitrogen fertilizer could boost…
Like it or not (and believe in climate change or not), Canada has committed to greenhouse gas emission (GHG) reductions, and the implementation will affect farmers. Part of GHG mitigation will certainly revolve around reducing nitrogen (N) fertilizer losses.“Farmers already have production challenges with growing crops, and this will add…
As the acreage of soybeans continues to expand in Manitoba, increasing to 2.2 million acres in 2017, developing beneficial management practices for soybean cropping systems is a priority. One of the questions surrounds nutrient management strategies for soybean, and in particular, yield responses to phosphorus (P) fertilizer."We recently completed a…
Crop rotations are designed to maintain crop and soil health to ensure long-term sustainability. Crop sequences deal with the effects of previous crops on current crop choice. A successful crop rotation encompasses many farm management components, including economics, fertility, soil biology, insect, disease, weed and pesticide considerations. The following eight…
Fababeans adapt well to cooler, wetter regions in Saskatchewan, and are proving to be a good option for growers who have been dealing with excess moisture and are looking for an alternative pulse option.
There’s good news for flax producers: if your soil has reasonable nitrogen (N) fertility, you can save on fertilizer costs because pushing the N rate seldom results in increased yield. The bad news is that flax, unlike canola or cereals, is not very responsive to N application, so yields are…
Pulse crops play an important role in many cropping systems. Along with field pea and lentil, growers are increasingly adding short-season soybeans into their crop rotations. Because soybeans are relatively new in Saskatchewan, growers and researchers are interested in how they compare in rotation to other pulse crops.
If you can’t measure something you can’t improve it. Since plant breeders want to develop improved crop varieties with bigger, healthier root systems to ensure the plants are well anchored in the soil and can take up plenty of water and nutrients, and agronomic researchers want to know whether different…
Three new early post emergent biologicals have been registered from XiteBio Technologies Inc: XiteBioYield+ for Canola; XiteBioYield+ for Corn, Wheat & Barley; and XiteBioYield+ for Legumes. These products are powered by the unique XiteBioYield+ platform based on patented phosphorus (P) solubilizing plant growth promoting rhizobacteria (PGPR). All these products can…
While drones have a foothold in the game of precision agriculture, some researchers are toying with the idea of using them as pollinators as well. Researchers ordered a small drone online and souped it up with a strip of fuzz made from a horsehair paintbrush covered in a sticky gel. The device is…
What nitrogen rates should you use with today’s high-yielding hard red spring wheat varieties to reach your yield and protein goals? And what are the optimum choices for nitrogen (N) fertilizer sources, placement and timing? A two-pronged research effort is underway to answer these crucial questions for Manitoba wheat growers.
Improving fertilizer use efficiency, reducing greenhouse gas (GHG) emissions and carbon footprints, thereby improving sustainability is becoming increasingly important to the agriculture industry and its markets. For agriculture, nitrous oxide (N2O) is a very powerful GHG, so reducing losses and intensity not only improves the GHG footprint of cropping systems,…
