<br />Main Reclamation Plots (Plots 1 - 96) <br /> <br />The general design and recllll1l8.tion treatments are shown on the diagram <br />on page 8. The amendments were applied in 1952 only. Twelve acre-inches <br />and 30 acre-inches of leaching water were applied in.l952. In 1954, an <br />additional 9 acre-inches of water were applied to the plots which original- <br />ly had received 12 acre-inches, making a total of 2l.acre-inches of water <br />applied fpr leaching purposes. <br /> <br />Lico barley, planted with Ranger alfalfa, was harvested in 1955. A <br />uniform application of 40 pounds per acre of nitrogen (N) and 300 pounds <br />per acre of phosphorus (P20t;') fertilizers was applied to the 'Plots before <br />they "ere seeded. No additional fertilizer was applied in 1956. <br /> <br />Two rates of surface irrigation were applied to both the drained and <br />.ub-irrigated plots in 1955. The west haJ.f of the drained plot area re- <br />ceived 11 irrigations (44 acre-inches) and the east half received 5 irri- <br />gations (20 acre-inches). The west half of the sub-irrigated area received <br />7 irrigations (28 acre-inches) and the east half received 4 irrigations (l6 <br />acre-inches) . <br /> <br />All plots were irrigated 4 times (l6 acre-inches) prior to the first <br />cutting of alfalfa in the 1956 season. <br /> <br />The water-table level in the drained plots was at a depth of approxi- <br />mately lO feet during the 1955 season and thus far in 1956 has remained <br />at approximately the same depth. The water table level in the subbed plots <br />was approximately 5 feet in 1955 and during the 1956 season has remained <br />at this depth. <br /> <br />The first cutting of alfalfa in the 1956 season was harvested June <br />20-2l. <br /> <br />Alfalfa Strip Tests (S-l to 8-6) <br /> <br />The alfalfa strip tests were established in 1953. The amendment and <br />leaching treatments applied in 1953 are shown on the diagram on page 8. <br />Alfalfa strips S-l, 2, and 3 have received surface irrigation, as well as <br />sub-irrigation, early each spring and after each cutting of alfalfa. All <br />alfalfa strips were flooded late in the fall of 1953 and 1955. <br /> <br />The first cutting of alfalfa in the 1956 season was harvested June 22. <br /> <br />Grass and Legume Nursery (N-l to N-30; o-l to 0-20) <br /> <br />r.... :- (". i'~ -' r., <br />.J '. h.-V-,- , <br /> <br />The grass and legume nursery was established in 1954 to stud;v the <br />adaptability of various grasses and legum3s to the site conditions. <br />Tl.enty-four plots which had no stand or poor stands were reworked and re- <br />seeded in 1956. In some cases new varieties were seeded. <br /> <br />A uniform application of 50 pounds per acre of Nand l69 pounds per <br />acre of P20::; fertilizers was made at the time of original seeding in 1954. <br /> <br />-7- <br />
