<br /> <br /> <br />The objective of the legume study by Or. Berg and Henry Barron was to <br />determine the potential of six commercially available legume species for <br />revegetation purposes on~three different sites at Climax. <br />On 17 September 1976 three sets of plots were seeded with six species of <br />legumes: <br />alfalfa, <br />birdsfoot trefoil, <br />cicer milkvetch, <br />red clover, <br />white clover, <br />alsike clover <br />Each set of plots was replicated two times. One set was seeded on good <br />topsoil. The other two sets of legume plots were seeded on a <br />nitrogen-deficient subsoil (glacial till) but in two different <br />microenvironments to evaluate the legumes' potential for buila.ing up the <br />soil nitrogen. <br />The plots occupied a total area of .0428 ha (4,608 sq ft). Each individual <br />plot was 3.7 m x 9.8 m (12 ft x 32 ft). <br />All species were seeded at the rate of 25 lb/acre. Each legume was <br />inoculated with the appropriate Rhizobium bacteria for N-fixation. The plot <br />area was fertilized with 200 lb p205/acre (as 0-46-0) and 100 lt~ K20/A (as <br />0-0-60). <br />In 1977 observations indicated that initial establishment of cicer milkvetch <br />was good and establishment of the other legume species was poor to fair. <br />Evaluation of the effects of potential nitrogen fixation on the soils has <br />not yet been undertaken. <br />36 <br />
