Ontario corn growers seem like sitting on sturdy yield potential as the the crop shakes off the results of cool late Could climate.
Early planting and a few well timed, albeit restricted, rains throughout the province have propelled the crop ahead. With herbicide utility anticipated to wrap up this week, growers will then flip their consideration to the nutrient wants of the crop, and whether or not side-dress nitrogen is required.
Primarily based on the outcomes of the Ontario Ministry of Agriculture, Meals and Rural Affairs’s annual Pre Facet-dress Nitrogen Check (PSNT) survey, soil provides of the important thing nutrient seem like in good form. Ben Rosser, OMAFRA’s corn lead, studies that the PSNT survey signifies the common PSNT worth for 2021 was 13 ppm, much like the long-term common of 12 ppm. The outcomes are primarily based on soil samples collected from 93 websites throughout Ontario from Could thirty first to June 2nd, 2021.
Total soil nitrogen supply (mineralization and losses) will be influenced by climate (soil temperature and moisture) every spring. At Tuesday’s digital Exeter/Mount Forest agribusiness assembly, Rosser stated that the absence of saturating rains has produced minimal loss. He famous that survey outcomes are similar to 2018 and 2020 — each pretty heat and dry springs, with some cool durations, much like 2021 situations.
For growers, the subsequent query is to find out their corn crop’s nitrogen wants. Rosser famous that the PSNT survey outcomes are a normal indication of soil nitrogen standing throughout the province and it’s vital for growers to pattern their very own fields earlier than making fertility administration choices.
On the assembly, Pioneer Hybrid gross sales consultant Russ Barker shared some ideas on what growers must be factoring into their choice. He famous that the absence of moisture means a lot of the nitrogen utilized previous to planting ought to nonetheless be obtainable to the crop. For growers who what to side-dress, the query now turns into how a lot do you apply. Some might wish to feed the crop to drive yield whereas others could also be leery of high-priced UAN 28%. That value will must be factored into the the equation, says Barker, however with new crop corn costs at $7 per bushel many growers might take into account it a good funding.
