Correcting soil deficiencies is dependent on your starting point and how well you follow the recommendations given in your Think Soil Analysis Report. In some cases we’ve seen it take as many as 5 years to bring soils up to maximum fertility.
In most instances we see reasonably good balance occurring within 3 years. You should begin to see significant improvements the first year and continued improvement thereafter. The bottom-line is to not expect your soil issues to be corrected in a single year. You many well see improvement in the first growing season but set your expectations for a longer period.
