Assessing the Type of Lodging

Farmers are advised to wait for three to seven days (or until the field conditions allow) after the lodging event to check their fields to determine the type and extent of injury. Two types of wind injury are commonly seen in corn:

• Root lodging: Plants get displaced from the vertical, but the stalk remains intact. Roots are partially displaced/lifted while staying attached to the ground. Generally, these plants recover naturally by bending upward over the following several days through normal gravitropic (against the direction of gravity) growth.
• Green or Stalk Snap (breaking of stalk): Stalks are broken from below or near the ear. In this case, affected plants cannot recover so they directly contribute to the yield loss, which is generally in proportion to the percentage of broken plants.

Management Recommendations

There is no direct management practice that can reinstate corn to its pre-lodged position. Instead, management is mainly focused on minimizing additional stress, allowing the crop time to recover, and evaluating potential impacts on yield.

• Farmers are advised to allow time (three to seven days) for recovery before making final evaluations on root-lodged corn fields. Corn expresses negative gravitropism, by which the plants that have their root systems still intact, will naturally stand back upright, often developing the characteristic “gooseneck” appearance.
• It is not suggested to manually straighten lodged plants. Attempting to unbend or stand plants upright can damage root systems and increase plant stress, often causing more injury than benefit.
• It is advised to delay non-essential field traffic/operations until soil is sufficiently dry to reduce additional root injury, soil compaction, and mechanical damage to lodged plants. Bringing equipment in lodged corn fields causes more yield loss than the lodging itself.
• Farmers are encouraged to continue scouting their fields for foliar diseases and stalk rots. Lodged plants usually stay wetter for long durations, providing conditions conducive for diseases such as gray leaf spot, northern corn leaf blight, and tar spot (where present). Plants injured by wind are more prone to stalk rots later in the season. Routine disease scouting should continue. Fungicide applications should not be justified by lodging alone. However, fungicide decisions should be guided by i) what the growth stage of crops is, ii) how much the disease pressure is, iii) how vulnerable the hybrid is, iv) what the weather conditions are, and v) what is the expected yield goal.
• Farmers are advised to evaluate the potential for nitrogen loss. For example, if heavy rainfall resulted in prolonged soil saturation, the likelihood of nitrogen loss should be assessed taking denitrification or leaching into account, which is very notable on southern NJ’s coarse-textured or poorly drained soils. Supplemental nitrogen should only be applied if field conditions, crop growth stage, and expected yield response justify additional applications.
• Fields should be reassessed after one week. Fields that stay severely lodged even after five to seven days may have suffered more substantial root injury and should be monitored closely throughout the rest of the growing season.
• It is advised to keep monitoring the stalk quality to help prioritize harvest (if and where needed). Wind-damaged fields should be scouted later in the season for stalk deterioration and increased lodging potential. Fields with decline in stalk quality should be prioritized for harvest to minimize additional yield losses.
• Affected farmers are advised to document and report affected acreage and estimated losses to their local USDA Farm Service Agency (FSA) office. Accurate reporting will be helpful in documenting the extent of damage and in supporting the evaluation of potential disaster assistance (if applicable).
• In case of suspected significant damage and if insured, it is suggested to make timely communication with the crop insurance provider (if warranted) and to follow policy requirements before making management decisions that could affect claim evaluation.

Dangerous heat will impact NJ and the region this week, with maximum air temperatures Wednesday to Saturday forecasted to reach the mid-90s to 105 degrees. The heat index, which factors in relative humidity, is expected to soar as high as 110 degrees. As a result, an Extreme Heat Warning has been issued for the majority of NJ (Wednesday to Saturday) with an Extreme Heat Watch being issued for the counties of Atlantic, Cape May, and Cumberland (Thursday to Saturday).

Precautions must be taken to prevent heat-related illnesses among the agricultural workforce:

1. Adjust work schedules and discontinue outdoor work during the hottest parts of the day.
   1. You can utilize the OSHA/NIOSH Heat Safety Tool (phone app) for site-specific heat indices to aid planning.
   2. Remember: heat index is measured in the shade and does not factor in the effect of work in direct sunlight.
2. Reduce workload intensity by increasing the number of workers per task, rotating jobs, and increasing the frequency of breaks.
3. Train everyone on the farm to recognize and respond to signs of heat-related illness in themselves and others.
   1. Reinforce training with signage such as this informative ‘Prevent Heat Illness at Work’ poster from OSHA which is available in English, as well as Spanish.
4. Keep hydrated! Cool water should always be available to everyone. Drink water constantly including before, during, and after work and encourage others to do the same. Sports drinks are generally not necessary when you drink ample water and eat regular meals.
5. Select light-colored, breathable clothing and a wide-brimmed hat. Your clothing must allow for rapid evaporation of sweat – the body’s mechanism for cooling.

Take extreme caution over the next several days to safeguard yourself and others from heat-related illnesses. For more resources on preventing heat-related illness among the agricultural workforce, visit our Heat Stress and Agriculture website. 

Importance of early-season establishment

The final yield potential (to be achieved later in the season) of soybean largely depends on how the crop established early in the season. If there is a poor emergence or is nutrient deficiency in early growth stages, it can decrease the final number of pods per acre and slow down the canopy growth. So, primary areas of focus during the early season are:

• To ensure uniformity in planting depth and better seed-to-soil contact for better emergence/stand count.
• To avoid planting into cold/wet soil to save emerging seeds from cold injury.
• To ensure strong nodulation for better rhizobium activity.

Nutrients Management Considerations

Soybeans, being a leguminous crop, don’t need nitrogen (for the most part as they can fix most of their nitrogen needs by themselves), but they need other nutrients:

• Phosphorus for early root development (to absorb water/nutrients and to anchor the plant in the soil) and nodulation. Very high (more than optimum) levels of phosphorus were seen in many New Jersey soils so, no phosphorus fertilizer is recommended for such soils. However, for the soils showing high/optimum phosphorus levels, it is still suggested to apply phosphorus at least in amount equivalent to that is removed by the soybean crop (40 lbs. P₂O₅/acre for a 40 Bu/acre of grain yield).
• Potassium for water regulation and pod fill (determinant of final yield). To the soils showing potassium in high levels, it is still needed to apply 55 lbs. of K₂O/acre for a 40 Bu/acre of grain yield, to account for the potassium removed by the soybean crop. For soils showing below optimum potassium levels, the rate of potassium is recommended to be higher than the 55 lbs. of K₂O/acre, depending on what the yield goal is. For a yield goal of 40 Bu/acre, if potassium levels are below optimum, potassium recommendations are to apply between 70-170 lb. K₂O/acre depending on the potassium levels (180-0 lbs. K/acre) shown in soil test (Mehlich-3). Also, it is important to mention the fields with soybean planted as a double crop, where potassium removal from the preceding small grain crop should be accounted for in fertilization planning by adjusting the soil test potassium results to avoid early season potassium deficiency. For example, a 45 Bu/acre soybean crop removes roughly 100–114 lb. K/acre (120–137 lb. K₂O/acre) from soil when potassium removed by the preceding small grain crop and its straw is also included with the potassium removed by soybean grain.
• Sulfur has been increasingly becoming critical for last two decades, especially in highly leached, low organic matter, and sandy soils because of the decrease in natural sulfur deposits in soil owing to the stricter environmental regulations after the enactment of clean air act of 1990. Sulfur recommendations for soybeans are 20-40 lbs./acre (if broadcasted) or 20-30 lbs./acre (banded).
• Manganese is the micronutrient that is seen deficient in most of the South Jersey’s coarse textured soils. The deficiency is visible in the form of green veins with yellowness appearing between the veins. For soils having the history of Manganese deficiency, recommendations are 15 lbs./acre (broadcast) or 5 lbs./acre (banded) of Manganese, if applied by soil. If a foliar application, recommendations are to apply three times (1^st application as soon as the symptoms appear, 2^nd application on later vegetative stage, and 3^rd at early pod stage) with each application of 0.5-2.0 lbs./acre.
• Maintaining pH between 6.2 and 6.8 is generally good for all nutrient’s availability. However, if pH is outside this range, the nutrients that are present in the soil still become unavailable to the soybean plant.

In many New Jersey soybean fields, mild potassium and sulfur deficiencies are more prevalent compared to visible nitrogen deficiency.

Management specific to the Southern New Jersey Soils

Southern New Jersey’s sandy soils lose nutrients rapidly due to high leaching, lose moisture faster during reproductive stages, and encounter nutrient stress even when soil test results say, “adequate level”. Therefore, split or targeted nutrient management and regular soil testing are very helpful.

In-season crop management

At R1 (flowering stage) to R3 (early pod set stage), it is suggested 1) to be watchful for yellowing on leaves or uneven canopy development, 2) to keep checking if nodulation working effectively (red/pink nodules signify better nitrogen fixation), and 3) to ensure no hidden potassium or sulfur deficiency, especially when high rainfall occurs (high leaching rate).

Takeaways (Summary)

Improved soybean yields in New Jersey are tied to 1) good early season establishment, 2) balanced nutrition of phosphorus, potassium (especially in double-crop soybean), sulfur, and manganese, 3) prudent monitoring of nutrient losses in sandy soils, and 4) timely field scouting during flowering and pod set. Taken together, productivity of New Jersey soybeans relies less on high inputs, but more on early-season balance (nutrition) and timely monitoring.
