Maryland Drought Update and Corn Nitrogen Timing | The Mill

Maryland Drought Update: Second Nitrogen Applications Continue as Barley Harvest Begins

Certified Crop Advisor Ben Hushon with The Mill joined Market Day Report this week from Dell's Generation farm in northern Maryland with a field-level drought update and a timely message for corn growers across the region. The rain that fell over the weekend was welcome. It was not enough. 

Ninety Percent of Maryland Is in Drought

The number Ben opened with sets the context for everything else happening in fields across the region right now. As of this week, 90% of the state of Maryland is classified as being in moderate to severe drought conditions. That is not a forecast or a projection. It is the current state of the ground beneath the most active growing season of the year. 

The weekend delivered a half inch to an inch and a half of scattered rainfall across northern Maryland and into Pennsylvania, and growers received it gratefully. Ben made the condition of the soil clear with a simple observation: standing in a cornfield after that rain, there was not a bit of mud on his shoes. The ground absorbed what fell and remained dry enough to walk without leaving a mark. That tells the story of where soil moisture levels stand across much of the region entering the third week of June. 

More rain is potentially in the forecast for later in the week, and Ben was watching that carefully. But the region needs sustained, meaningful rainfall across a wide area to meaningfully move drought conditions, and scattered events are not accomplishing that. 

Second Nitrogen on Corn Cannot Wait

With the drought as a backdrop, the agronomic priority this week is completing second nitrogen applications on corn before the crop's demand for that nutrient accelerates beyond what is already in the ground. 

Ben has been consistent in this message across recent appearances: the target timing for topdress nitrogen on corn in this community is around V6, which corresponds roughly to knee-high plants. The field Ben was reporting from has corn at or approaching that stage, and second nitrogen applications are actively underway across the community. 

The urgency behind that timing is not arbitrary. Ben explained directly that from this point forward, over the next 10 to 14 days, the corn plant's daily demand for nitrogen is going to climb exponentially. That is not gradual. It is a sharp upward curve driven by the rapid vegetative growth that characterizes corn from V6 through V10 as the plant builds the structural foundation that will support the developing ear. 

Nitrogen that is not available in the root zone when that demand peak arrives cannot be recovered later in the season. Getting topdress applications completed now, before that curve steepens, is one of the most time-sensitive agronomic decisions of the summer. 

The half inch of rain that fell over the weekend also matters directly for nitrogen management. Dry fertilizer applications need moisture to move into the soil and become available to the root system. A well-timed rain following a topdress application significantly improves nitrogen uptake efficiency and reduces the risk of volatilization loss from surface-applied urea. 

Barley Harvest Is About to Begin

While corn management is dominating the day-to-day conversation, another milestone is arriving on the farm calendar. Ben reported that two growers told him on the morning of his appearance that they expected to fire up their combines and begin barley harvest later this week. 

Barley is typically the first small grain to reach harvest maturity in Maryland, often preceding wheat by two to three weeks. Its arrival signals that the small grain harvest season is opening across the Mid-Atlantic, with wheat following closely behind depending on conditions. 

For operations that grow both barley and corn, the overlap in timing creates familiar logistical pressure. Equipment decisions, labor allocation, and field prioritization all come back to the table as harvest begins on one crop while intensive management continues on another.
