Condition of European and US winter crops poles apart

AS CHRISTMAS approaches and the brumal cold descends upon the northern hemisphere, the winter-crop planting campaign across the European Union and the United States has concluded. The juvenile plants are bracing themselves for the usual weather extremes, and eagerly awaiting a nice white blanket of snow for protection.

Favourable weather conditions across most of Europe in October and November meant that the cereal crop was planted within the traditional sowing window in most regions. There were early delays due to excessive rainfall in some central and eastern regions, but they managed to catch up with the drier weather in November.  On the other hand, the rapeseed area is expected to be smaller than last year after October rains caused waterlogging in a number of regions. The fields only dried out enough for seeding activities just as the planting window was closing. Some later-season varieties were planted in France and Germany, but the many paddocks earmarked for rapeseed were switched to cereals or not sown at all.

Europe has been warmer than average in recent months, with most of the agricultural regions of northern and eastern Europe experiencing the warmest autumn on record. Those countries on the Scandinavian Peninsula and surrounding the Baltic Sea have seen the most significant variation from average. The warmer temperatures, coupled with average to above-average soil moisture in most regions of Europe, has been ideal for crop establishment.

Hardening is the bio-physiological process by which winter cereals build low-temperature tolerance to withstand the freezing conditions that occur during the winter dormancy period. The mild weather conditions mean that this hardening process only started when the cold weather arrived in early December, much later than normal. As a result, frost tolerance remains low in most of the western, southern, south-western and central cropping regions of Europe.

French plantings below average

France is the biggest winter-crop producer in the EU, and the country’s farm ministry had expected a dramatic rebound in the country’s planted wheat area this year after rain severely hampered the 2019 sowing campaign.  However, its first estimate fell well short of market expectations. The ministry pegged the country’s soft winter wheat planted area at 4.73 million hectares (Mha), up 12.4 per cent on the 4.21Mha planted in 2019. Nonetheless, that was 1.9pc below the five-year average and significantly lower than the market projections of 5-5.2Mha.  The winter barley area was estimated at 1.26Mha, up 6.6pc from the previous year but 5.7pc below the five-year average. Rapeseed plantings were estimated at 1.13Mha, an increase of 1pc on the area harvested in 2020 but a massive 17pc below the five-year average.

The French wheat crops will enter winter dormancy in good shape. The soft wheat conditions are estimated to be 96pc good to excellent compared to 73pc at the same time in 2019. Just 4pc of the soft wheat crop was rated as poor against quite a substantial 26pc in mid-December last year. The winter barley fields are also looking good, with 94pc of the crop rated as good-to-excellent, up from 75pc 12 months earlier.

US dry of concern

On the other side of the Atlantic, much of the US winter crop area has been battling drought conditions this fall. The worst of the dry conditions is primarily affecting the western half of the country: west of a line from the Dakotas south to Texas. However, the moisture deficit has been creeping eastward with each week of below-average rainfall.  Around 97pc of the High Plains which encompasses parts of Kansas, Nebraska, Wyoming, Colorado and the Dakotas is experiencing moderate-to-severe drought conditions, with 51pc falling into the severe category. Total state-wide rainfall registrations for North Dakota in the three months to the end of November ranked the third driest on record.

Large parts of the Midwest are starting to feel the pinch, with 39pc of the area dealing with some degree of drought or abnormal dryness. And nearly all of the Southern Plains states are experiencing moderate to extreme drought conditions.  Some much-needed precipitation fell in portions of the US hard red winter wheat (HRW) growing areas over the past two weeks. The ambient temperatures were cold enough for some to fall as snow which will help protect the wheat from potentially damaging cold snaps in coming weeks.

The crop is now in dormancy, but almost the entire HRW area is in moisture deficit and still needs significant moisture before the spring to ensure the crop emerges from dormancy in good condition. A considerable proportion now has a thin snow cover, and that will be available to the plant in the spring as long as it doesn’t evaporate beforehand due to abnormally high temperatures.

The 10-day forecast has above-average temperatures and above-average precipitation for the majority of the winter wheat areas east of the Mississippi River, and above-average temperatures but below-average rainfall for the winter wheat areas west of the Mississippi River.

In its last crop progress report for 2020, the US Department of Agriculture called the winter wheat crop 52pc good to excellent, up from 43pc a week earlier, reflecting the rainfall over the past couple of weeks. The crop was 92pc emerged compared to 89pc last week and a five-year average of 91pc.

Kansas is the biggest wheat-growing state in the US, and the picture is not good for most winter-crop farmers. The crop is well behind the national average at 33pct good to excellent, and is in desperate need of good rain.

The long-range forecast from the National Weather Service (NWS) suggests above-average temperatures and below-average precipitation across most of the HRW belt for the first quarter of 2021. day period. The extended outlook remains a concern for the HRW crop in the Southern Plains. The robustness of the crop will be reduced by the dry conditions, leaving it vulnerable to winterkill issues if temperatures plunge into negative territory.

Made in spring

Winter crops are made in the spring, and that is still months away for the Northern Hemisphere grower. The European farmer is rightly optimistic about new-crop prospects at this point in the season. This is offset by drought conditions across much of the US winter-crop area. The one thing that appears common on both continents is the crop’s susceptibility to winterkill should there be sustained cold snaps in regions where the crop has inadequate snow cover.
