Care must be taken to avoid an excess of water in the soil and to prevent heavy crusting or packing. Good subsoil drainage is necessary for the successful irrigation of all the crops studied. At Rocky Ford the climate is somewhat different from that of northern Colorado, and the crops need different care in the practice of Fig. 2j. —The cook wagon. This is the boarding house for the thrashing crew. Alfalfa was irrigated on an average of times; oats, times; wheat, times; beans, times; beets, times; cantaloupes, times; and cucumbers, times. A man irrigating alfalfa but three times would turn on the water the first time May 1 to 15; next, June 1 to 10; and lastly, June 25 to July 5. If a fourth irrigation is given it usually comes in September, or after the last crop is harvested. Some farmers irrigate as often as six times for alfalfa. Grain, beets, and beans are usually irrigated at planting time, so as to furnish moisture for the germination of the seed. Cantaloupe and cucumber crops are irrigated to germinate the seed. Water to germinate the seed is applied to row crops by making furrows at the time of plant- ing by attaching ditching shovels to the planter. Other irrigations are applied by methods similar to those explained for the northern Colorado regions. In the latter part of May cucumbers are given an irrigation to bring up the seed. The other waterings follow at regular intervals up to about August Please note that these images are extracted fr
