Should soil loss due to crop (tuber) harvesting be part of soil loss during erosion studies under natural rainfall?

Since this soil is loose, and I think there will be no significant soil attached to the tuber during harvesting, does this underestimate the soil loss washed off under this study?

If you are presenting results of soil loss in a numerical value (e.g. in kg of soil lost to the area considered per unit of time (day, month, year)), and have several numerical values for this parameter, then you should be able to undertake a statistical test to assess the significance of the results. Even if you only have one value, publicising your work in a paper is useful for other as long as you detail the experiment, method of interpretation in an objective and scientific manner. If people like the experiment, you may get some funds to do more and be able to "validate" your results i.e. find relevant factors in crop harvesting that affect soil loss!

Thank you Ben

My Dear Dennis Edem; In general two to three year crop data can give reliable results and also chances to get published in an standard research journal which have good impact factor. Thanks
