Rolling around the dream of planting a meadow

"...First, remove weeds and turfgrasses from the area. Digging them up would be the most labour-intensive way of doing this, and risks moving weed seeds to the surface, making the problem worse. An easier, often more effective strategy is to smother or solarize the existing vegetation, which requires patience..."

Waste Not, Want Not

"...The precepts of circular economy—reusing water, using biodegradable plastic, composting food leftovers so they can be returned to the soil rather than become landfill—are among the hottest ideas of our century.   But what about recycling what our food becomes after we eat it? Yes, that means excrement, a critical substance in the thoroughly functioning circular economy, seems to be left out of the equation..."

Choose the Correct Cover Crop

"...“In organic farming, any strategy to preserve soil fertility is particularly important. When animal husbandry is not included in the farming system, green manure is crucial to preserve or increase soil organic matter content,” writes Anna Lenzi, who led a team that analyzed different cover crops to determine how they well support soil health and increase tomato yield..."

Flooded fields impacting fertilizer decisions

"..."With the drought in a lot of the area last year, it left a lot of excess nitrogen in the soil and we were counting on that as being money in the bank," he said. "There was a lot of soil sampling being done and we usually anticipate that that is going to be there, ready for use this next year and farmers were planning to adjust their fertilizer rates accordingly. Now with this amount of rain and potential flooding, people are starting to get a bit antsy about that..."

Beyond wars and pandemics, the climate crisis is the greatest risk to food supply chains Corporate Knights

"...The economic effects of the Russian invasion of Ukraine will likely ripple for years, if not decades. Global food systems have not been spared from disruption, as the war has pushed the price of wheat and other commodities to their highest in years. This disruption, like that from the pandemic, highlights some of the risks built into our highly efficient, trade-dependent food supply chain..."

When to Consider Forage Rejuvenation

"...Factors that cause a decline in forage production may include problems with soil fertility, salinity or texture, issues in long-term management or even unfavourable weather such as drought or untimely rain or frost. The cause of forage production decline is generally a combination of one or more factors. In situations where weather is not a factor, improper forage management and low soil fertility are the two most likely causes..."
