Abstract:

The tremendous cost of repairing highway slopes eroded because of poor vegetative cover is a serious problem. Flat pea (Lathyrus sylvestris L.), a perennial herbaceous legume, is an excellent plant for erosion control and a good soil stabilizer. Because it was not being used in the state, it was essential to determine its adaptability to the climate and to the acidic, infertile cut and fill slopes that lack topsoil. A greenhouse experiment was conducted using 2 soils, one very acidic and low is fertility and the other only slightly acidic and of medium fertility, to determine the plant's response to lime and fertilizer. The plants in the very acidic soil that received fertilizer and both lime and fertilizer responded well. It was found that the pH requirement of flat pea is not so critical as that of crownvetch. Based on the results obtained in the greenhouse studies, successful plot plantings and seedings were made throughout the state over a 4-year period. Seedings made in the spring or as dormant seedings in late fall before the ground freezes produce best results. Late summer and fall seedings are risky because the seedlings generally have too much competition from grasses and weeds.
