While a low pH can reduce corn or soybean yields by 40% or more, there’s a surprising shortage of recent research about how lime is tested and graded and what impact it actually has on soil pH and crop yield. These were among the issues raised at a recent conference of lime-industry representatives and USDA-ARS and Iowa State University (ISU) soil researchers. The answers could impact input costs and yields as well as nutrient-management effectiveness. </p></div> <div class="og_rss_groups"></div><p><a href="http://cornandsoybeandigest.com/fertilizer/rethink-soil-lime-approach" target="_blank">read more</a></p> http://cornandsoybeandigest.com/fertilizer/rethink-soil-lime-approach#comments Fertilizer Micronutrients Soil Acidity Mon, 24 Mar 2014 18:29:00 +0000 89891 at http://cornandsoybeandigest.com <p>To get the right pH, Iowa State University soil scientist Antonio Mallarino suggests more frequent sampling for pH with corresponding and variable-rate lime applications. Get the pH right in the top 6 inches, and don&rsquo;t over-lime for no-till or pastures if the laboratory calculates a 6-inch depth, because it moves only 2 to 3 inches.</p> Photo: Harlen Persinger Phosphorus, sulfur, zinc uptake in corn http://cornandsoybeandigest.com/fertilizer/phosphorus-sulfur-zinc-uptake-corn <div class="node-body gallery-body"><p>“Many farmers don’t fertilize for sulfur and zinc.

As nitrogen application rates increase from 0 to 220 lbs./acre (horizontal axis), the rate of N<sub>2</sub>O emissions (vertical axis) increase the most steeply above 180 lbs., this University of Michigan research shows. Although nitrogen placement, timing and formulation concern farmers, nitrogen <em>rate</em> has the highest correlation with these emissions. Data represents 6 fertilizer nitrogen rates and 8 site year averages.</p> Source: Michigan State University
