Starter Fertilizer in Winter Wheat

Winter wheat planting season is soon at hand. Questions often abound on the issue of fertilization rates, timing and placement. Over the years, a lot of research has focused on starter fertilizers or split-applying nitrogen (N) and other nutrients. In general, phosphorus placed with the seed has been shown to increase tillering and total grain yield. Nitrogen is more uncertain, due to the possibility of salt burn and the associated yield losses.

Soil Penetration Resistance as a Soil Health Indicator

Soil penetration resistance is an indicator of soil compaction and the force required for root growth through the soil. It can be measured in the field using a tool called a penetrometer.

Growing Connections: An Organizational Map of the South Dakota Local Food System

Behind every farmer’s market, community supported agriculture share, or local food event is a network of advocates, educators, and organizations that make it all possible. The South Dakota Local Food System map illustrates the organizations that strengthen local food through a variety of roles and functions.

How to Stop Drift

The goals of applying any crop protection products include: increasing effectiveness, mitigating drift, and maximizing profits. We will focus on mitigating drift, even though all three interact with each other.

Field Studies: Replicated Comparisons vs. Side-by-Side Comparisons

How should a basic study be set up or laid out in the field? One very common approach is to divide a field in half and compare the halves or possibly compare two fields in close proximity and see which variety or practice yields highest. This approach can end with very misleading results because of the variability that exists across a field or fields due to many factors.
