Excerpt from Report of the Porto Rico Agricultural Experiment Station, 1919 During the twenty years of the American occupation in Porto Rico agricultural production has increased tremendously, due principally to the development of large areas as single units. There seems to have been little or no departure from this tendency, despite the fact that efforts along educational lines and through legal enactments have been made to curtail large land holdings. Instead of cutting down large holdings, they have actually been increased through pur chase or under long leases.

Excerpt from Annual Report of the Porto Rico Agricultural Experiment Station, 1904 Another insular appropriation of $650 has been expended for fencing, and while the work is not complete, yet it has enabled us to inclose nearly the entire tract and to build a number of cross lines. The irregular form of the station grounds gives us a border line of something like $5 miles. A further insular appropriation of $100 has been used for painting the various buildings of the station.

Excerpt from Annual Report of the Porto Rico Agricultural Experiment Station for 1901 It is hoped that land may be Obtained for the permanent location Of the station in the near future and that it will be possible to greatly develop the work Of the station during the coming year. Considering the large agricultural interests Of the island and the variety of work which needs to be done by the station, the appropriation for its sup port by Congress should not be less than per annum. In addition to this, money will be needed for the purchase of land, erec tion of buildings, and equipment of the station. The station will, therefore, need such financial assistance from the Territory of Porto Rico as was given in the other States and Territories. There are no results Of experimental work to be reported at this time. This report is, therefore, chiefly confined to a statement of the agricultural conditions and needs Of the island. As seen by the writer in the course of such an agricultural survey as he has been able to make in the space of nine months.

Excerpt from Report of the Porto Rico Agricultural Experiment Station, 1926 Corn from the temperate regions fails to prosper in the Tropics, and the native corn does not develop well. The station is endeavoring to produce good varieties by crossbreeding and by selecting from the native type. Both methods are showing promise.

Excerpt from Report of the Porto Rico Agricultural Experiment Station, 1914 As the products come primarily from the soil, it is to the soil that the highest skill should be applied. Contrary to general belief, tropical soils are not naturally fertile. It is true that in virgin forests. Where humus deposits have accumulated for many years, they are quite productive, but that fertility must be very carefully conserved or it will be lost, and that, too, not by cropping. Denuded of trees, tropical upland soils soon lose their fertility by the washing and leaching Of rains and the action of the burning sun. Where cov ered with forests, especially of leguminous trees, they are productive for coffee, cacao, etc., but when bare they become hard and compact, not holding moisture and producing only scant, unprofitable grasses. It is a slow and tedious process to bring these lands back to the pro duction of profitable crops or trees. It is true that the growing season in the Tropics is 12 months of the year, yet the quick growth of vegetables known in the north in the spring is not Obtained in the Tropics. Persons from the tem perate zones, seeing the misery among many Of the rural population, ascribe the condition to shiftlessness, while in the main it is due to ignorance. The natural conditions are such that the small planter can not get the immediate results with salable crops that are Obtained in the spring season in the north. What is the cause Of this? In northern climates the freezing Of winter puts the soil in a favorable condition or releases plant food therein, producing conditions for rapid spring growth. In the Tropics these favorable conditions do not exist, and plants which require a long period of growth are the most successful. The use of fertilizers becomes more necessary. In Porto Rico the level lowlands are by far the most productive. The great problem in connection with these soils is one of rotation. At present they are largely devoted to sugar cane, but natural condi tions have already compelled the adoption Of rotations, and this will be accelerated by reason Of change in economic conditions and the consequent lowering in the price of sugar. Doubtless many of the cane lands will go into grass, with a resulting increased production of live stock.

Excerpt from Report of the Porto Rico Agricultural Experiment Station, 1921 Dairying. - The output of milk per native cow is low. In a study made by the station to ascertain the quantity of milk yearly given by the native cow, it was found that 324 head averaged 6. 47 pounds per day per cow. During the eight months the records were kept the average yield _per cow was pounds, or at the rate of 2 2 pounds per annum.

Excerpt from Report of the Porto Rico Agricultural Experiment Station, 1917 During the year the work of surveying and listing the bat guanos in the caves cf the island was completed, and studies were made of their value and the availability of their phosphates. This investiga tion has resulted in a greatly increased use of the deposits. It is hoped at a future date to take up work with the phosphate deposits in Mona Island, which lies in the channel 40 miles west of Porto Rico and belongs to her. This work, as well as that of studying methods for obtaining potash from the mother liquor from the salt works at Salinas, has had to be temporarily postponed.
