When fields stay wet
NOVELTY, Mo. – Heavy rainfall is becoming more frequent across Missouri, leaving producers dealing with saturated soils, ponded fields and flooding even before the 2026 growing season began. Understanding how excess water affects crops—and what steps can help in the short and long term—can protect yield potential and improve field resilience, says University of Missouri Extension state soil science specialist Gurbir Singh.

Building resilient, profitable farms
CEDAR HILL, Mo. – In the hills outside St. Louis, creeks swell fast after hard rains, and fields can pay the price. At Big River Grain and Cattle, Daniel Bonacker recalls, repeated flooding was carrying away topsoil. In 1983, Bonacker’s grandfather switched to no‑till farming, which minimizes disturbance of the soil. This reduces erosion by improving the soil’s ability to absorb and hold water.

Managing potassium and phosphorus when prices are high
When high fertilizer prices shock the system, farmers often ask if they can delay their P and K applications until next year, when prices may be lower. The quick answer is yes – if your soil test levels are near recommended levels, says University of Missouri Extension state nutrient management specialist John Lory.

MU Soil and Plant Testing Lab moves to cheaper, quicker testing
The MU Extension Soil and Plant Testing Laboratory is transitioning to a new soil nutrient extraction method, called Mehlich-3, which has become the industry standard for soil testing. Adopting the Mehlich-3 method enhances laboratory efficiency and enables the laboratory to provide a more complete nutrient analysis in a single test while keeping overall testing costs lower.

10 ways to manage high input costs in 2025
ST. JOSEPH, Mo. – University of Missouri Extension agronomist Wayne Flanary says 2025 likely will be a year when corn producers need to batten down the hatches to offset low sale prices and high input costs. MU Extension ag business economist Ben Brown and others predict that corn prices will fall below the $4.30 mark by the end of 2025, a marked drop from $6.54 per bushel in 2023.

Post-drought pasture improvement takes more than rain
LINNEUS, Mo.– Heavy rainfall throughout much of Missouri on July 2 may have lessened worries about drought damage in pastures, but one good rain won’t undo the damage to mismanaged pastures during two straight years of drought, according to two University of Missouri Extension specialists based at the MU Forage Systems Research Center in Linneus.

With high fertilizer prices, are you better off buying fertilizer or supplemental hay?
COLUMBIA, Mo. – Increases in fertilizer prices add to the cost of growing forage for grazing. This leads farmers to ask if they should buy hay or fertilizer, says University of Missouri Extension nutrient management specialist John Lory. Comparing the benefits of buying hay vs. applying fertilizer for better yields is complicated, but it is crucial to the bottom line, says Lory.

MU Extension agronomist offers tips to offset high nitrogen prices
GALENA, Mo. – If there was ever a time to do a soil test, this is it, says University of Missouri Extension agronomist Tim Schnakenberg. Rising fertilizer prices make it too expensive to guess on how to apply nutrients, says Schnakenberg. Soil tests can prevent buying and applying fertilizer where not needed.

Does wheat need N in fall?
Yes, of course wheat needs N in fall. Timely planting and decent fall tillering are very important to wheat yield potential. And adequate N supports that tillering.But soil has N, regardless of whether you put any there. Is it enough, or not enough, to maximize wheat yield potential?
