Title: Microcomputers for Design and Analysis of Land Grading for Drainage
Author: Disrud, Lowell
Description: Due to the heavy soils and flat slopes of the Red River Valley, drainage problems occur. Spring runoff stands in natural depressions causing planting problems.Heavy rains reduce crop yields. The grading of land, the cutting and filling of areas of a field to produce a uniform slope has been used for many years to on irrigated land to improve water flow and distribution. The redistribution of these fields renders other adjacent land useless. The introduction of computer software to aid in the creation expedited the process of alleviating these problem fields. The program evaluates both the cost of leveling and calculates the potential increase in revenue due to increased yields realized from the improvement of surface drainage. The software allows the user to evaluate the potential returns on land leveling for a 3 crop rotation for a period of 15 years. It utilizes net present value analysis to account for the distribution of cash flows over the full life of the investment. In addition, it allows for the calculation of return for each dollar invested. Computer software allows farmers to maximize their bottom line, profit.
