Manganese Deficiency showing in Soybean

It is that time of year again when we are beginning to see manganese deficiency in soybeans. Manganese defiiciency is a common and recurring deficiency on the sandy soils of southern New Jersey. Left untreated manganese deficiency can reduce yields. Deficiency results in reduced leaf chlorophyll content. This commonly appears as interveinal chlorosis (the tissue between the veins turns yellow while the veins in the leaf remain green). Extensive research by RCE soil fertility specialist Dr. Joe Heckman has demonstrated the economic benefit of applying manganese fertilizer to deficient soybeans. Information about manganese deficiency can be found in the RCE publication "Soil Fertility Recommendations for Soybeans".
