'Bee'ing good stewards and applicators

The future use and availability of crop protection products, plant food and other agricultural inputs de­pend on good stewardship. Apply­ing them properly and wisely casts a positive light on agriculture and our ability to be environmentally responsible, which includes protect­ing pollinating insects such as bees, butterflies and moths. Whether you’re applying a product yourself or relying on a custom applicator, adhering to the same principles of stewardship is important.

Avoid off-target movement

The dangers of physical drift and herbicide volatility are well docu­mented when it comes to damaging a neighboring crop. However, these factors affect protection of polli­nator habitats and natural areas as well. When spraying an insecticide, there are a couple of things to keep in mind. Many habitats adjoining crop fields play an important role in maintaining the species diversity of pollinators and flowering plants. These “micro” habitats of less than an acre can contain staggering numbers of species. Keeping these habitats clear of physical drift is important for stewardship of these species. This applies to both herbi­cides and insecticides. Physical drift from insecticides can kill non-target insects such as pollinators, and drift from herbicides can kill flowering plants vital for pollinators.

Using precision equipment to make sure our field borders are spatially correct can help us avoid damaging these valuable adjoining habitats. If a waterway, buffer strip or pollinator plot is added near a crop field, be sure that boundary is edited to exclude those areas.

The time of day for an insecticide application is also an important consideration. If good control of the target pest can be achieved any time of day, making insecticide appli­cations during evening hours can miss most pollinator activity. This can greatly decrease the amount of non-target insects affected.

Follow the 4Rs

As a best practice for fertilizer appli­cation, MFA recommends following the 4Rs of nutrient management. Most of these practices deal directly with using current agriculture technologies to ensure nutrient applications stay out of surface and groundwater resources. Water quali­ty is something we need to contin­ually manage, but nutrient applica­tion effects can be minimized if we are good stewards.

Right Source: Use the type of fertilizer product that meets your crop needs. For example, if you are applying phosphorous on soybeans, choose a product that minimizes the amount of nitrogen applied. This ensures that extra N isn’t in the soil profile to be transported away from the field.

Right Rate: Soil testing is critical to being a good steward of nutri­ents. The better the soil data in hand, the better the recommenda­tion for product application can be. If there are high soil-test levels in a field due to past applications of livestock manure, there is little benefit to excessive amounts of fertilizer. In fact, there will likely only be negative environmental consequences to high applications in these areas. We have plenty of low-testing soils, and those are the areas where our maximum fertiliz­er investment will pay the highest dividends.

Right Time: Recent data from Missouri shows we are losing sig­nificant amounts of nutrients from our fields in the large runoff events that seem to occur every spring. This highlights the need to ensure nutrients are placed at opportune times. For nitrogen management, this means as close to plant uptake as possible and ideally in a split application format. Other nutri­ents may do better with a different strategy. Phosphorus, for example, may be best applied in the fall when runoff events aren’t as frequent. This allows maximum time for the P to bind to soil particles before the large spring precipitation events occur.

Right Place: Equipment mainte­nance is a must anytime precise ap­plications are necessary. Spreading equipment is no different. Pan and scale testing are critical to ensure the amount of product coming out of the truck is accurate in both pattern and quantity. If you own spreading equipment, be sure you are comfortable in all the calibration techniques necessary.

Overall, having more data in hand, taking a critical look at timing and using the right product in the right amounts can have a big impact on the landscape around us. Consider these factors as you move into crop year 2020. We not only farm in MFA trade territory, but we all live here, too.
