Interpretive Summary
| 2015 | Meta-analysis uses statistical methods for combining results from multiple studies on a specific topic with the aim of identifying patterns, sources of disagreement, or other relationships that may exist among study results. Simply put, meta-analysis can be thought of as "conducting research about previous research" (after Wikipedia, 2015). Phosphorus fertilizer placement and interactions with tillage have been studied extensively in corn-soybean systems in the USA. |
