Brief Project Summary:
Using strip-tillage and a deep placement of fertilizer can help soybean yield. Researchers will compare broadcast fertilizer, deep placed fertilizer in strip-tilled plots, with broadcast fertilizer in no-till. The goal is to demonstrate that soybeans can produce high yields with these fertilizer scenarios rather than only fertilizer applied after corn production. They also hope to show long-time release of nitrogen can increase soybean yield with the utilization of an encapsulated nitrogen source.

Information And Results
Project Summary

Strip-till Broadcast Fertilizer, Strip-till Deep Placement Fertilizer and No-till Broadcast Fertilizer. On farm site with a complete randomized block design and 4 Replications of each treatment. NPKS with a mix of nitrogen sources used including Duration 120 as one of the slow-release products. Planter in furrow starter fertilizer will be used with both 30” and 15” rows with in the trial design as additional treatments.

Project Objectives

Proposal description: Strip-till Broadcast Fertilizer, Strip-till Deep Placement Fertilizer and No-till Broadcast Fertilizer. On farm site with a complete randomized block design and 4 Replications of each treatment. NPKS with a mix of nitrogen sources used including Duration 120 as one of the slow-release products. Planter in furrow starter fertilizer will be used with both 30” and 15” rows with in the trial design as additional treatments.

Proposed methods/tactics: Dates of field operations, Date of planting and emergence, Stand counts, Canopy closure Digital images starting at V3 to R8, stay green rating, Yield, Moisture, seed samples and analysis.

Project Deliverables

Proposed outcomes: We will be able to demonstrate high yield soybeans using strip-till and deep placement of direct fertilization rather than only fertilizer after corn production. Also will show the long time release of nitrogen at about R3 can increase yield with the utilization of an encapsulated N source. The in furrow starter will be in comparison to the deep banded and broadcast fertilizer. Increase in time to canopy will be measured by staging and comparison to untreated and farmer normal practice.

Communications plan: Jason Solberg will post on social media drone pictures and time lapse pictures through the growing season.

Benefit To Soybean Farmers

We will be able to demonstrate high yield soybeans using strip-till and deep placement of direct fertilization rather than only fertilizer after corn production. Also will show the long time release of nitrogen at about R3 can increase yield with the utilization of an encapsulated N source. The in furrow starter will be in comparison to the deep banded and broadcast fertilizer. Increase in time to canopy will be measured by staging and comparison to untreated and farmer normal practice.

The United Soybean Research Retention policy will display final reports with the project once completed but working files will be purged after three years. And financial information after seven years. All pertinent information is in the final report or if you want more information, please contact the project lead at your state soybean organization or principal investigator listed on the project.
