Sulfur Fertilization of Alfalfa in the Mountain Valleys of Southern Idaho1/
نویسندگان
چکیده
Areas of S deficiency are still being identified in the Pacific Northwest even though S has been applied to some soils in this region for at least 50 years. Recent studies dealing with the S fertilization of legumes for the Northwest have been conducted by Pumphrey and Moore (1965a, 1965b) in northeastern Oregon; Smith, et al., (1968) in western Montana; Dawson (1969) on pasture legumes in western Oregon; and Koehler (1965), and Roberts and Koehler (1968) in Washington.

Indexes of Sulfur Deficiency in Alfalfa . I . Extractable Soil SO - S ' 4
Sulfur deficiencies occur on many of the undeveloped agricultural soils found in the mountain valleys of the western United States; however, the majority of the S soil-test correlation studies have been conducted on leached and weathered soils. Identification of S deficiency on alfalfa (Medicago sativa L.) growing in three mountain valleys permitted the collection of S soil-test correlation dat...
متن کاملMorphological analysis of glaciated valleys in the Zardkuh Mountains, Iran
The morphology of glacial valley can be described in terms of power law or quadratic equations fitted to valley cross-profiles. These two models are used to study the cross-profiles of 86 valley cross-profiles in the Zardkuh Mountain in order to understand the evolutional patterns of valleys. Assessment of using the power law function indicates that b values for both valley sides range from 1.0...
متن کاملNitrogen use efficiency and life cycle of nodules in alfalfa after different mineral fertilization and soil cultivation
Nitrogen use efficiency and life cycle of root nodules in alfalfa after different mineral fertilization and soil cultivation practices were studied. Field trial was conducted in the Institute of Forage Crops, Pleven, Bulgaria on leached chernozem subsoil type and no irrigation. The next treatments were tested: i) for fertilization as follows: N0P0K0 (control); N60P100K80 (an accepted technology...
متن کاملNitrogen, Sulfur, Potassium and Phosphorus Fertilization in Alfalfa When Are They Necessary?
Determining when applications of nitrogen (N), sulfur (S), potassium (K) and phosphorus (P) fertilizer are needed is important to maintain alfalfa yield and quality. The Western U.S. is diverse in terms of climate, soil types, irrigation water need and availability, historical nutrient use and alfalfa production systems. Therefore, few generalizations hold regarding the timing and location of N...
