Kansas State soil scientist Dorivar Ruiz Diaz saysfarmers should be aware that that dry conditions in much of Kansas this year could impact their ability to get an accurate soil analysis. For example, a soil’s pH level – a measure of how acidic or basic the soil is – can be misleading depending on the accumulation of solids or hydrogen at the surface.

We know that P is a critical element required for crop growth and development, and if deficient, the lack of P can significantly reduce crop yield. While application of P fertilizer is common, it is not always required to achieve maximum yield.

Recent Fertilizer Canada lobbying has morphed the fourth principle from Right rates to holding the line at rates without “a mandatory reduction in the use of fertilizers.” These are 3R and STIR (same to increased rates) principles. Is this right?

For this episode of the No-Till Farmer podcast, brought to you by SOURCE by Sound Agriculture, we're joined by Steve Wilkens who farms about 1,000 acres of Wisconsin ground that his family has worked since the 1850’s. In 2021, Wilkens recorded a yield of 315.4 bushels per acre, enough to claim second place in the Wisconsin No-Till Non-Irrigated category for the National Corn Grower’s Association Corn Yield Contest.

Introducing the new Guardian SC1, an autonomous, unmanned aerial sprayer from Guardian Agriculture. This all electric machine can carry a 50 gallon payload while covering approximately 40 acres in a day, with minimal downtime due to its battery power. Employing a Swiss army knife approach to drone application, the SC1 can spray a variety of crop types across seasons without being limited like other ground based sprayers.
