Pot experiments were conducted in the greenhouse to determine the nutritional requirements of Poa annua . Total top yield was greater for annual bluegrass grown in silt loam soil than in loamy sand. In loamy sand a large decrease in clippings, crowns, and roots was obtained at a pH of 4.5 compared to pH 6.5. Differences between pH levels were not significant in the silt loam soil. N, P, and K contributed most to top growth in the order mentioned. Results of this study indicate that annual bluegrass has the ability to grow better than Kentucky bluegrass, Poa pratensis L., at a low pH level in a silt loam soil.
