Cotton is commonly planted in furrows in a similar manner as listed Fig. 105 —^Broadcast seeder and cultivator.

There are some tools designed to cultivate the land before planting, others that cultivate to cover the seed sown by them, and still others are designed for alfalfa fields (Fig. 105). The ordinary cultivators, however, are used for intertillage. Why Crops Are Cultivated.—^The objects of intertillage are commonly given as: (1) to kill weeds; (2) to conserve moisture, and (3) to aerate the soil.
