Synopsis

Excerpt from Citrus ture in Porto Rico

That the citrus tree is not very exacting as to its soil requirements is well illustrated by the fact that the groves are found on soils covering a wide range from beach sand to heavy clay. A systematic study of existing groves reveals differences in growth of tree due to soils which were not readily discernible at the time of planting. This is true especially of the region between Bayamon and Arecibo, which is bordered by the ocean on one side and by the railroad and in places by the public highway on the other. The soils of this region vary from sand that is almost devoid of colloidal matter to clay containing less than 25 per cent sand. The growth of the trees fur nishes information regarding the chief limitation of each soil type. The white sand is poor because it does not retain enough moisture and plant nutrients to supp] the needs of the trees under existing conditions. The darker san containing 2 to 3 per cent colloidal matter, of which about 1 per cent is organic, is excellent, provided the subsoil is pervious and the water level is not too variable. The red sandy soils containing upwards of 10 per cent colloidal matter are suitable for tree growth, provided they do not cement. Cementa tion is caused by the high amount of iron and the colloidal state in which it is present in these soils, and it prevents the trees from devel oping properly. The clay soils in this region vary from 20 to 60 per cent clay and are similar to those found in other regions.

The soil at Plantaje, both surface and subsoil, in which the first commercial grove on the island was planted, consists of shell sand. With the formation of land at this point, silt was deposited in the lower places, whereas the slight ridges remained practically pure sand. A heavy hammock growth developed, especially in the silt covered areas, and after it was removed considerable humus re mained.
