Impacts of hot and dry summer are felt across all types of farms

It has not been an easy growing season.
“It was the first time in 14 years that we have planted corn in June, and we were borderlining it,” says Jackie Lamb of Lamont Farms in Godmanchester, referring to the cold and wet weather that kept farmers off their fields this spring. Then the temperature spiked up and the rain stopped, leaving thirsty crops to grow under a baking sun that lasted into late August.
Lamb points out that if corn doesn’t get what it needs at critical points during growth stages, the plants just don’t produce as many kernels. Soybeans are more resilient, she explains. “You need a great year to have a great yield of corn. We can have a medium year and still have a decent yield of soybeans.”
As organic producers, Lamb says they have adapted their practices to be more flexible. She and partner Shawn McNamee have incorporated a lot of hay into their rotations and have worked to build organic matter in their soil, which improves its ability to retain moisture and absorb heavy rains. This leads to better effective rainfall and reduced erosion.
The pair also raise sheep, and this summer’s extreme heat was a worry. Large fans installed in the barns has helped, and while electricity bills jumped, McNamee says they did not lose a single animal to heat stress.
Grazing sheep were also moved to specific shady paddocks that are reserved for heat waves. Their wool acts as an insulator, and Lamb says that ensuring higher vegetation in pastureland can reduce the soil temperature significantly. “If they are lying down on a piece of ground that is 10 degrees cooler than an exposed piece of ground, that also helps,” Lamb explains.
“We have to be conscious of the heat. We have to plan for it every year now,” adds McNamee.
Hard on morale
Market gardener Jess Elwell, who is an owner at the Jardins de la Résistance organic farm in Ormstown, says the hot and dry conditions this year caught them off guard after several years of managing wet weather. An employee was essentially dedicated to irrigation this summer, meaning their small team was down one person in the field. “We can only irrigate so much at one time because we only have so much pressure in our tank for the well,” she explains.
Relying on irrigation drip lines or sprinklers also meant losses in direct-seeded crops that did not germinate properly. “I don’t know what it is about rain that’s so much better than water, but vegetables like the rain a lot better,” Elwell explains, noting that a lot of plants just don’t like stress. All of this is exacerbated in a greenhouse, where temperatures can quickly reach sweltering levels.
“This is the first summer in my 16 years of farming where I was like, maybe I’m getting too old for this,” she says. “Now that the temperature has dropped, it’s not that bad. It’s hard for morale on the team,” she adds, while pointing out how everything seems like a big deal when its hot.
“It’s been rough,” she admits. “We have managed to pull through. We have a really good team, and we’ve pulled it off. But it hasn’t been easy this year for sure.”
