New precision planting product concept applies N through knife concealed in gauge wheel
Precision Planting’s latest product concept for nitrogen (N) placement, Conceal, consists of a double set of injection knives that slide into a special groove in the planters’ gauge wheels. Liquid fertilizer is injected through the knife directly under the gauge wheels for consistent and optimized placement.
“We’ve done a lot of research in recent years to investigate the value and effectiveness of providing nitrogen at the right time and in the right place,” says Jeremy Hodel of Precision Planting.
This concept not only puts the nutrients in the right place for the seeds to access nitrogen, but also gives growers the benefits of a very simple design that can handle different residue and soil conditions. Instead of risking a knife hanging on its own, Conceal’s integrated knife and gauge wheel system allows it to handle residue like a coulter typically would and offers the simplicity of a knife.
“Concealing is stiff in normal operation, but it will give, if necessary, to protect the knife,” says Jason Stoller of Precision Planting. A snap spring is the secret to Conceal’s success in protecting itself in harsh conditions.
For growers who apply N in a 2 × 2 band, Conceal will fit perfectly into their planting routines. Farmers attending the 2017 Precision Planting Winter Conference were quick to learn about the new technology, and Stoller sees farmer-applied nitrogen as “an important opportunity for farmers to optimize their nutrient programs in a tough farming economy. “.
Conceal will be tested by a handful of farmers under the watchful eye of Precision Planting this spring. As to when it will be available for sale, we’ll know more after testing in 2017.
