Creating Management Zones Using Electrical Conductivity

The first step to practicing zone management is to identify the variations that control yield. There are various methods for characterizing soil variations within a field, and among them, electrical conductivity measurement is one of the most-reliable.

Fall Soil Sampling

With fertilizer prices on the rise, it’s more important than ever to understand your soil test levels and crop response to applied fertilizers. Fall is a great time to soil sample before freeze up.

Using Feedlot Manure to Reduce Crop Production Costs

Livestock waste can be a valuable source of crop nutrients when correctly managed. Taking a strategic approach to feedlot manure application can increase the value of manure as part of your overall system.

Determining an Economically Optimal Nitrogen Rate for Corn in 2022

While we can't know what the prices of corn and nitrogen fertilizer will be next year, it is very important to understand how the level of both prices will influence corn profitability for 2022.

Nitrogen Credit: The Rest of the Story

We have all been programmed to think of soybean as fixing nitrogen from the atmosphere and adding nitrogen to the soil. The SDSU lab and most other labs give nitrogen “credit” when another crop follows soybeans.
