Depletion Of Subsoil Moisture By Apple Trees And Other Woody Species, C. C. Wiggans
Depletion Of Subsoil Moisture By Apple Trees And Other Woody Species, C. C. Wiggans
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
This project began in 1934 and ended in 1955. The work of Kiesselbach, Russel and Anderson indicated that depleted subsoil moisture might be the reason for the loss of many orchards and the injurious effects noted on native woody forest species. Most of the work in apple orchards was done at the University Fruit Farm at Union, Nebraska. Samples were also secured from commercial plantings of apples and other woody species in areas ranging from Rulo, near the Kansas-Nebraska border, to Florence, just north of Omaha, to Lincoln and several points in central Nebraska.
Sulfur Fertilizers For Alfalfa Production In Nebraska, R. L. Fox, A. D. Flowerday, F. W. Hosterman, H. F. Rhoades, R. A. Olson
Sulfur Fertilizers For Alfalfa Production In Nebraska, R. L. Fox, A. D. Flowerday, F. W. Hosterman, H. F. Rhoades, R. A. Olson
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
In order to elaborate all aspects of the sulfur problem in alfalfa production, a series of field, greenhouse and laboratory experiments was initiated to determine: 1. The influence of sulfur fertilization on the yield of alfalfa in Nebraska. 2. The influence of sulfur fertilization on the protein, vitamin A, and sulfur contents of alfalfa. 3. The sulfur supplying capacities of various soils under field and greenhouse conditions. 4. The sulfur content of precipitation at widely scattered points in Nebraska. 5. Soil properties associated with sulfur deficiency. 6. Optimum methods for estimating the sulfur status of soils by soil testing. The …
