Weather Stressed Crops: Solutions for Excessive Rainfall

It has been a soggy year for a significant number of growers, and lately my conversations keep coming back to one topic: crops stressed by too much rain.
Excessive rainfall typically causes the following:
· Leaching and/or denitrification cause the loss of nitrogen, sulfur, boron, and molybdenum.
· Root systems become oxygen starved.
· Nutrient uptake slows because roots are damaged or inactive.
· Photosynthesis and energy production decline.
· Disease pressure often increases.
The goal after a wet period is to restore energy production, root activity, nutrient uptake, and nitrogen metabolism.
Each of the following nutrients plays a specific role in that recovery:
· Nitrogen helps rebuild chlorophyll and vegetative growth, often the most deficient nutrient after heavy rain.
· Sulfur is critical for amino acid formation and nitrogen efficiency.
· Potassium helps water regulation, stress tolerance, enzyme activation, and carbohydrate movement throughout the plant.
· Magnesium is the core component of chlorophyll; supports photosynthesis recovery.
· Molybdenum supports nitrate reduction and nitrogen assimilation.
· Manganese also supports photosynthesis as well as antioxidant systems.
· Zinc supports hormone production and new root growth.
· Boron supports sugar movement and reproductive development.
· Calcium helps rebuild cell walls and root tips.
· Iron supports chlorophyll production, especially in saturated soils with a higher pH.
Creating a treatment that contains everything can be challenging but luckily for us we have the products to make much of this happen!
According to my research, the nutrients that provide the greatest impact after excessive rainfall would be nitrogen, sulfur, potassium, magnesium, molybdenum, manganese, and zinc. These work together to restore photosynthesis, root growth, energy production, nitrogen metabolism, stress tolerance, antioxidant production, and carbohydrate movement.
When it comes down to it, stress is stress. Even though this paper focuses on excessive rainfall, most of my suggestions work for plants under any stress condition.
Our RePAC technology is particularly important following stressed conditions because the acetate base along with the potassium, magnesium, and calcium nutrient partners not only contribute carbon and support energy metabolism but restore stomatal function and nutrient movement throughout the plant, support photosynthesis recovery and help rebuild cell walls and root tips that strongly influence new growth.
I broke it down for these common crops:
· Corn: N, S, K, Mg, Mn, Mo.
· Soybeans: K, Mg, Mn, Mo, B, Co.
· Peanuts: K, Ca, Mg, B, Mo.
· Cotton: K, Mg, Mn, B.
· Watermelon/Tomatoes: K, Ca, Mg, B.
A one-fits-all treatment would be:
Ingredients (per acre)
· 2 quarts of 21% N
· 1 quart of K-Flex
· 1 quart of Microzone Mg
· 1 quart of CropMax
Directions
1. Apply with 15 plus gallons of total solution per acre through ground or aerial application.
2. If you use a drone to apply this mixture, reduce the rate of nutritional products to achieve a 50:50 water-to-product ratio. Every year is different, but if you run into crop conditions brought on by weather-related influences, contact me and we will work through the treatment options based on your crop and environmental conditions!
