What is it about?
I measured the effect size of popular plant residue application methods for plant growth such as leaving on soil (or incorporating into the soil), cutting into pieces, waiting for fungi propagation, and dispersion. Then, I found the effect of dispersion has a very large effect size. In addition, I found that the interaction of dispersion and incorporation has a far more large effect size.

Why is it important?
Crop residue returning is an essential of sustainable agriculture. However, most of the people don't care about the way of returning. Therefore, the results of experiments for plant residue application is unstable. The way of returning crop residue has a huge effect so it also may affect all kind of field experiment.
Perspectives
We will be able to get more clear results in field experiment or actual crop production If we pay more attention to the way of crop residue returning. The same thing can be said for the meta-analysis of field research.
