    Can less tillage grow more corn? And what happens when we diversify crop rotation instead of planting the same crop every year? Recently, de Camargo Santos et al. (2025) published a factsheet ‘Corn performance improved by long-term diversified crop rotations and no-tillage in Ohio from 1962 to 2024’ (https://ohioline.osu.edu/factsheet/anr-0183 to answer these questions.

    Looking closely at fertilizer input needs is one way to deal with tighter profit margins. The biggest concern with reducing fertilizer is, of course, loss of yield. The best strategy to reduce fertilizer input while avoiding yield loss is to know the ability of soil to supply nutrients through soil testing. It is impossible to predict the impact of changes to a fertility program without measuring soil-available phosphorus (P) and potassium (K).

    Over the last 50 years, both crop and livestock production systems in the U.S. have become increasingly specialized and separated. A two-year Ohio State project has partnered with 31 working Ohio farms to examine the economic, ecological, and social impacts of specializing or integrating these farming systems.

    As I write this article on Monday afternoon, showers and a few embedded storms are rolling across the Buckeye State. However, for southern and southeastern Ohio, this has largely not been the case for the last several weeks. Precipitation over the past 30-to-60-days is running 25-75% of normal, with some parts of Pickaway, Ross, Noble, Morgan, Washington, Monroe, and Belmont Counties receiving less than 2 inches over this period (Figure 1).
