Looks like no one has taken the time to answer your interesting question. Let me try... firstly, simple answer is no. However, the benefits of fall tilling are many. Here in the western U.S. our spring weather is not often conducive to early tilling. Vegetable crops do best when planted after the soil has reached a specific temeprature... usually around 60 to 65 degrees F. That only happens after about the middle of May here. Before that, the soil is just to soggy to till.
Fall tilling provides the opportunity to pull up all those weeds that were hiding under the foilage of your carefully tended vegetable crops. It also provides the opportunity to till in a good compost and additional fertilizer if needed. Over the winter months the compost and fertilizer will break down in the subsurface soil and be ready for use by the plants in the spring.
We like to till the soil in two directions 90 degrees to one another, rake it fairly smooth and leave it alone.... just walk away and leave it alone... It'll be ready for you come the Vernal Equinox... Disfrute su jardin!
