Piney Woods Lands.
In the piney woods the natural pasturage is composed mainly of broom sedge and wire grasses. During the growing season, from spring till late fall, these grasses furnish fair pasturage, but through the rest of the year they merely enable animals to exist. What can be done towards converting these poor native pastures into good permanent pastures? There are three possibilities in the light of our present knowledge. On better soils good Bermuda pastures can be developed, or where the lands are moist, as on most flatwood areas, carpet grass may be used. On the drier and poorer soils, Natal grass is the only one that has given much success.
How can Bermuda or carpet grass pasture best be established? The sure method is to stump your land and plow it, and then plant the Bermuda by the vegetative method in spring, or any time thereafter in summer, during the rainy season. At the McNeill station in Mississippi, located on land much like that of the northern tier of counties in Florida, they have developed the following method: Plow furrows about ten feet apart between the stumps in spring, and stick in a root or sprig of Bermuda about every ten feet. At McNeill it is found necessary to use a little fertilizer to insure the growth of these Bermuda plants. During the following winter the stumps are removed, and then in spring the land is plowed and Lespedeza seed sown. Enough Bermuda has grown in the furrows to insure a stand of Bermuda, and this is supplemented by the Lespedeza. Indeed, the first season the Lespedeza will furnish more pasturage than the Bermuda. Lespedeza is rather a tricky plant in Florida and is hardly worth consideration except in the northern part of the State.
On most of the Florida flatwood soils carpet grass is much more aggressive than Bermuda, and in time will, if left alone, completely replace the Bermuda. To a large extent this can be obviated by plowing the pastures whenever the carpet grass seems to be obtaining the upper hand. Unfortunately, we do not know the relative values of equal areas of Bermuda grass and of carpet grass where the latter is most aggressive. Carpet grass does not grow so tall, but is green for a longer period. It may, indeed, be found more economical not to try to save the Bermuda after the carpet grass crowds it. From observations, I am inclined to believe that neither the carrying capacity nor the feed values per acre of the two grasses is greatly different on most flatwood soils. If this be true, it would not be economy to go to any particular trouble to retain the Bermuda instead of the carpet grass.
At McNeill the pasturage on areas that have long been closely grazed is carpet grass. Unfortunately, no experiments have been conducted to compare these two grasses as to ease of establishment and as to carrying capacity. Carpet grass produces abundant good seed, and therefore spreads much more rapidly than Bermuda, which rarely produces seed in humid regions.
It is found necessary to remove the stumps at McNeill, because for the first year or two on the plowed ground, weeds, especially "fennel" or "Yankee weed," appear abundantly, and must be mowed or they will kill the grasses by shading. Mowing with the stumps on the land is impracticable, as the weeds conceal many of the stumps.
Whether it is practicable to establish good permanent pastures without stumping and plowing the land is yet an unsolved problem. About every Florida settlement where the town cattle graze, there is good pasture, commonly carpet grass. You will find just this on the outskirts of Jacksonville. Such pasturage has been established by heavy continuous grazing, under which conditions the broom sedge and wire grass are exterminated, while the creeping carpet grass comes in and persists. It may be that the manure of the animals is also a factor, and there can scarcely be a question that the trampling helps. As an example of this kind occurs about nearly every Florida town, it would seem as if it could be duplicated on cattle ranches. I have suggested to several cattlemen that it is worth trying on a scale by three methods: (1) Simply burning the native grass in winter; (2) burning, followed by disking or harrowing; and (3) plowing among the stumps.
If possible, carpet grass seed should be scattered on each area, and in all cases close grazing should be practiced. Unfortunately, carpet grass seed cannot be secured commercially, except in small quantities at high prices, but it is easy to cut the mature carpet grass in fall from a pasture and cure the hay. The carpet grass can then be sown simply by scattering the hay. Whether any of these schemes will work out satisfactorily still remains to be determined.
As to Natal grass, I have already mentioned that this succeeds better on the poorer and drier pine lands than any other grass yet introduced. Thus far it has been exploited purely as a grass for market hay. On this basis many hundred acres were planted in Lake County and elsewhere. Grass culture purely for market hay is a very precarious proposition. The proper agricultural economy is grass for live stock, selling only the surplus to the market. Notwithstanding the very large acreage planted to Natal, I have been quite unable to secure satisfactory data as to its value for pasturage, measured in carrying capacity and satisfactory gains. It seems to me, from the slender data I have been able to secure, fairly probable that Natal will prove a valuable grass for combined hay and pasture on the soils to which it is so well adapted, but of course it can hardly be expected to yield enough to justify the extravagant prices paid for land planted to Natal.
