I recently read through Stratus Ag Research’s 2026 Planter Box Market Assessment survey data and it was a treasure trove of insight into the segment.

For background, a planter box product is an input added directly into the seed box or seed tender at planting alongside the seed as it moves through the planter. Historically, this primarily meant talc, graphite, or other seed lubricants that improved seed flow and singulation, but the category has expanded into multifunction products that carry one ore a combination of micronutrients, biologicals, biostimulants, insecticides, or fungicides.

The Planter Box concept has remained incredibly fascinating to me as an input delivery mechanism — the main reason being that the planter box enables a mechanism for applying input products beyond the traditional spraying, fertilizer applied, or seed treatment methods. It allows for getting inputs at the roots without an extra pass, or much extra work for the farmer.

The Stratus Planter Box Market Survey for corn and soybeans showed that 58.5% of growers are already using at least talc/graphite:

Notably, the next largest segment was biostimulants, with between 20% and 25% (depending whether corn or soybean) using a multi function product.

Only 2.9% said they had not considered using one, which reinforces that the concept is well known. On top, when factoring the multi-function numbers, viewing the planter box as a legitimate means for applying crop inputs has moved into the mainstream.

But what is required to move it even further?
