However, in a detailed study of five benchmark agricultural catchments, between 6 and 26% of the soil still had excessive soil test P levels, showing the legacy effect of over application of P fertilisers and manures in the past.
At greater depths, he found the dark, richly organic soil of the original prairie, a benchmark for the soil level when European farmers arrived in the 1850s.
Three typical benchmark-slopes with layered soils are adopted to demonstrate the efficiency, accuracy and robustness of the suggested procedure, and advantages of the proposed method with respect to alternative methods are discussed.
Further to the existing data, the databases could be completed with the proposal soil characteristics that would provide free information on the benchmark characteristics of different foundation soils in a modern, fast and easy manner, and thus facilitated its preliminary assessment.
