Muck Lands.
On the muck lands the problem of pasturage is easy. At least four grasses, namely, Para, Carib, Rhodes and Bermuda, especially Giant Bermuda, yield wonderfully. The enormous area of muck lands in Florida, especially in the Everglades, can, it would seem, be utilized only with the aid of livestock. While there may be some fairly difficult problems to solve in handling live stock on muck soils, especially in the wet season, there can be little doubt that grass and live stock will insure the permanency of these lands. Under continuous cultivation there is a constant shrinkage in muck soils, but with grass and live stock this is nearly, if not quite, counterbalanced.
Carib grass on muck soils is, from limited data, superior to Para grass both in yield and quality. On other types of soil Para will outyield Carib. Rhodes grass does wonderfully on muck soil, and, indeed, on most rich soils. Giant Bermuda is far coarser and more vigorous than ordinary Bermuda. It will succeed wherever ordinary Bermuda will grow, and, in addition, seems much better able to withstand flooding.
Temporary or annual pasture crops are mainly important in connection with swine raising. Various systems of such crops have been devised to furnish successive pastures. Florida has a long list of such crops that can be utilized. Among them are oats, rye, rape, sorghum, peanuts, cow peas, chufas, sweet potatoes, corn and velvet beans. Under certain conditions the cattleman may have to utilize one or more of these crops, but corn and velvet beans is the one that is the most important.
The story of the velvet bean is really one of the romances of agriculture. Introduced into Florida about 1875 from some unknown source, it first attracted attention as a forage about 1890. Until 1914 it was but little grown outside of Florida. In 1915 the crop was certainly less than 1,000,000 acres. In 1916 it had increased to 2,500,000, and in 1917 to about 6,000,000 acres. The explanation of this remarkable increase was the finding of earlier "sports." Three of these appeared independently—one in Alabama, two in Georgia. These early varieties immensely increased the area over which the velvet bean can be grown, so that now it embraces practically all of the cotton belt. These early sports of the old Florida are most grown, but the Chinese velvet bean, introduced by the Department, and the hybrids developed by the Florida Experiment Station, are important. In spite of vigorous search, the native home of the Florida velvet bean yet remains unknown, but it is probably in the Indo-Malayan region of Southern Asia.
The importance of the velvet bean to the live stock industry now developing in the South can scarcely be over-estimated. Grown with corn, it increases the corn crop year after year, and besides furnishes a large amount of nutritious feed to be eaten by the animals when the grass pasture season is over. It reduces greatly the cost of finishing of beef animals for market. This year the velvet bean has been no small factor in helping out the great shortage of foodstuffs, quantities of them having been shipped to Texas. Finally, it has resulted in a new industry for the South, namely, the manufacture of velvet bean meal, which has already won for itself a large demand.
