The roots keep on growing during the fall until the weather becomes very cold, therefore they have a good chance to benefit by the nitrates that are formed during thelatter part of summer. They have the advantage of spring-sown grain crops in this regard. Since root crops are such heavy feeders, and since the ground should be kept thoroughly cultivat- ed during their growth, they are generally used as the crop to which the largest quantity of barn- yard manure is applied. In addition to heavy manuring, another very important necessity is thorough cultivation of the soil before the sowing of the seed. The root is thick and compact; it has to push down and out on all sides. If it can- not go straight down it will twist about or push itself partly out of the ground. For well shapen and perfect roots, then, we must have a well-tilled and well-drained Fig. 26.—Sugar beet on left grown in good soil, well drained and well cultivated ; beet on right grown in rough Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original James, C.
