Presently permissible erosion limit is computed based on soil depth and soil properties for conservation planning. This method should be tested or verified by using soil formation rate or soil regeneration data at a given site of place.
In Europe, the current mean soil erosion rate is about two to three orders of magnitude larger than its natural regeneration rate. That means that soil genesis is quantitatively almost irrelevant at shorter timescales w..r.t. to human-induced soil erosion. Therefore, erosion thresholds cannot be substantially relieved by consideration of soil genesis - at least at moderate lattitudes.
The soil production rates can be quantified by using in-situ produced cosmogenic nuclides and chemical mass balances. We have quantified soil production rates and human-caused soil erosion rates in the tropical highlands of Sri Lanka. There is a huge difference. Our publications may give some guidance for your question.

Thank you for your reply. I will appreciate you if you kindly share this two publication with me. I am really interested to know how the soil production rate can be measured. Recently I have come across some paper on soil production rate published in Science (Journal). I look forward to get a copy of your study.
These articles are not based on soil genesis. Is spite of this, I hope it would be useful:

Dear Debashis - A pdf is attached for your perusal. It is on red ferruginous soils of India. Please refer to 'Section 10' and you may get some points to consider.
To Dr. D K pal
Sir,
Thank you very much for sending me the paper. I have gone through it. Section 10 has given some idea about it. However, is there any method to quantify soil formation rate for different regions of India?
