Methodology
METHODOLOGY:
A foliar 28-0-0 fertilizer with 72% of it’s N in the slow-release triazone form was applied at 2 gal/acre with 15 gal water @ R3 in early August.
Results
RESULTS:
There was no significant yield gain in the high yielding soybeans associated with the foliar N fertilizer application. To be significant at 95% a yield change of +/-3.15 was required. However, other fields in previous years have seen significant yield increases.
