Clean Culture with Cover-Crop System.—In the clean culture with cover-crop system of management the general practice is to keep the ground clean by frequent culti- vations from the time the ground is plowed or disked in the §27 IN GULF-COAST STATES 19 fall or winter imtil the beginning of the rainy season about the first of June, when the cover crop is sown. In the sandy soils of the gulf-coast states the plowing should be no deeper than necessary to turn the ground over and bury the cover crop under the furrow slice. Citrus trees are shallow feeders, and deep tillage means a loss of many small fibrous roots. In fact, some good managers never plow the soil in the groves, but depend entirely on the disk harrow and other harrows for all their cultivating operations. Cultivation should follow immediately after the plowing of the soil and should be continued up to the rainy season in. Fig. 10 June or until the cover crop is sown. A disk harrow is some- times used after plowing on soils that are inclined to be heavy and occasionally during the year, but in most groves, especially those in which the soil is sandy, the Acme harrow if used often enough will keep the soil in good condition. 23. The frequency of cultivation depends somewhat on the weather. As the principal advantage of cultivation is the conservation of moisture, the ground should be worked more frequently during a dry period than during a wet period. It is a good plan, provided it is the time of the year when It is desirable to prevent the loss of moisture from the soil,. Please note that these images ar
