I once knew of a field, of about two acres, sloping to the south and entirely surrounded by heavy timber, on which two or three tomato crops were failures when other fields on the same farm gave large yields, but after the timber on the south and east had been cut away this field generally gave the largest yield in the neighborhood. =Location.=--While exposure is in some cases an important factor in determining the total yield an acre, and so the cost, the location of the field as regards distance from marketing point and the character of the roads between them is of far greater importance in determining the cost and profit of crop, but one which is very often disregarded. The marketable product of an acre of tomatoes weighs from 3 to 30 tons, which is not only more than that of most farm crops, but the product is of such character that its value is easily destroyed by long hauls over ordinary roads. It has to be marketed within a day or two of the time it is in prime condition, regardless of the conditions of the roads or weather; so that it is quite deceptive to estimate the cost of delivery at the same rate a ton, as for potatoes or wheat, for it always costs more, and sometimes several times more, to deliver tomatoes than it would to deliver the same weight of less perishable crops. In most cases the cost of picking and delivery is one of the most important factors in determining profit and loss, particularly when the crop is grown for canning factories, where one often has to wait for hours for his team to unload. These conditions make it very important that the field be located within a short distance of, and connected by good roads with the point of delivery. =Early maturing fruit.=--Where early maturity is the great desideratum the exposure of the field is often very important. It should, first of all, be such as to secure comparative freedom from spring frosts so as to permit of early setting of the plants and the full benefit of the sunshine as well as protection from cold winds. There is often a great difference in these respects between fields quite near each other. Professor Rolfs, of Florida, mentions a case where the tomatoes in a field sloping to the southeast and protected on the north and west by a strip of oak timber were uninjured by a spring frost that killed not only all the plants in neighboring fields, but those in the same field farther away from the protecting timber. Such spots should be sought out and utilized, as often they can be used to great advantage. Immediate proximity to large bodies of water is sometimes advantageous in the South, but in the North it is often disadvantageous for early fruit because of the chilling of the air and the increased danger of spring frosts, although affording protection from those of early fall. Here, too, proximity of field to shipping point and distance and transportation rate to market are very important factors affecting profit on the crop.
