In like a lion, out like a lamb. That’s how March weather has long been described. But farmers don’t care if they hear a roar or a baa right now, as long as they hear thunderclaps. And lots of them.
Over 2/3 of the USA is experiencing at least moderate drought conditions; one-quarter of the country is in a severe drought or worse. This goes beyond the usual suspects. No parts of California are even affected.
I saw planters rolling in Texas last week. We’re weeks away from seeing widespread field work across the fruited plain. And much of the USA’s major crop-growing regions are seriously impacted by low moisture.
Over 80% of Illinois is in a drought, 35% in severe drought and 13% in extreme drought. These severe/extreme areas are located in the middle of the Prairie State, home to the most fertile soil in the world. This severe drought swath extends across the top farmland of Indiana. It also impacts the Cornhusker State, where 77% is in drought and Missouri with 56%.
Among the SEC states, the only thing drier than their recent college football fortunes is their soil. Over 98% of Arkansas is in a drought. Virtually all areas of Georgia, Alabama and the Carolinas are impacted, as are Texas and Oklahoma. And over two-thirds of Florida is in an extreme drought.
You may be thinking, why worry about winter drought, especially when most crops aren’t even planted yet?
Snow and rain during the offseason is critical for recharging subsoil moisture. This is the layer that begins about a foot below the surface and can extend about six feet. It can provide a bank of water that roots can reach during the season. This helps the crops perform productively even during periods of low rainfall. Lack of subsoil moisture puts crops at risk and often leads to yield reductions. So yes, the moisture you get, or don’t get, in the winter can impact crop production several months later.

Curly fries, waffle fries, spicy fries or… regen fries? Soon, these may all be choices in the frozen foods aisle, at least if McCain Foods has a say in it. And as the world leader in prepared potato products, purchasing 6.8 million tons of spuds annually, McCain carries a strong voice. Their commitment to sustainability includes a pledge to have regen
How Deep Should You Plant?
This time every year, hemming and hawing would rage on at the Nichols Farm. Dad and Uncle Gary would not only agonize over when to plant, but how deep to drop the seeds. From “It’s been awfully dry, we better wait for a rain” to “It still feels a little wet, maybe we should run the field cultivator over it again” (gulp) to my annual favorite: “But If we get a beatin’ rain, those tops will turn into a layer of concrete.” Prompting, “Then we’ll have to rotary hoe.” Ah yes, the rotary hoe. A toolbar affixed with several blades resembling weapons thrown by Ninjas: rotating steel wheels featuring curved teeth. It’s used to break up crusted soils (and in some cases to incorporate herbicide) formed by those beatin’ rains.

How many kernel rows, or rounds, will an ear of corn have? That’s being determined right now in my cornfield. My corn has hit the critical V6 growth stage (in just 31 days, no less). Next to emergence and pollination, V6 is one of the most significant times of the plant’s life. This is when the
