Available in PDF, EPUB and Kindle. Book excerpt: The Alberta Soil and Feed Testing Laboratory has received a total of 62,500 farm soil samples since April of 1962. The data concerning the farm soil samples were keypunched on computer cards and then transferred to magnetic computer tape. Techniques were devised and computer programs written to analyze the available information concerning the nutrient status of Alberta soils. Summaries were made for nitrate nitrogen, phosphorus, potassium, and pK values for the top six inches of soil according to soil-climatic areas as well as for counties and other districts. The most accurate and promising summaries were the soil nutrient maps of Alberta showing areas of high and low nutrient concentration. The mapping of such data for the province involved trial runs with several different types of mapping techniques. The final selection was a circular weighted moving average technique, using townships as the basic mapping unit. The application of this technique resulted in the production of excellent and interesting soil nutrient maps displaying easily distinguishable trends. The same mapping function was applied to a smaller area, as well as a field, to determine further the nature of trends existing at these various levels. Careful consideration was given to crop types and time periods over which all summaries and mappings were conducted. Preliminary work was carried out to determine the sampling accuracy associated with the soil test measurements, both on a field and regional basis. Phosphorus and nitrogen tests showed the most variability in sampling. The A.S.F.T.L. data contained "ceiling values" for nitrogen and potassium which would strongly bias the results. This was moreso for potassium than for nitrogen. Models were developed and "probable" values were simulated to replace unknown values. The result was a much more plausible and accurate distribution of these data. Large amounts of information were handled rapidly and efficiently with the aid of the electronic computer. All numerical calculations carried out within the manuscript were performed by programming the computer. Without the aid of this electronic device, only a small fraction of the results obtained and reported in this thesis would have been possible.
