Pasture or woodland?
1947
Arny, A.C.
1. Yields of pasturage from areas in the shade of occasional oak trees at noon in permanent pastures did not differ significantly from those in adjacent open areas. 2. Open areas in permanent pastures in two counties in south-eastern Minnesota averaged 1.38 tons of pasturage having a net computed income value of $25.60 as compared with an average of 0.31 ton with a net computed income value of $3.27 from adjacent wooded areas. One acre of the open pasture was equal to 4.5 acres of the adjacent wooded area in the production of pasturage and to 7.8 acres when compared on the net income basis. 3. The open pasture on these farms produced ample feed during May and June for dairy cows producing 25 pounds of milk daily rapidly to gain their fill. During no month in the grazing season did the adjacent wooded areas produce adequate pasturage for high-producing dairy cows. 4. The protein content of the pasturage from the open areas averaged 16.8% protein compared to 12.4% for that from the adjacent woodlands. This difference was probably due to the higher percentage of white clover in the pasturage from the open areas. 5. The open areas produced pasturage containing 305 pounds protein per acre which was five times the 60 pounds in the pasturage per acre of woodland.
