G77-328 Irrigation Water Quality Criteria, Gary W. Hergert, Delno Knudsen

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide is intended to provide guidelines to help understand and interpret chemical water quality test results.

All well and stream waters contain dissolved minerals. The amounts and kinds of minerals vary from one location to another and may vary with time. When irrigation water is applied, the mineral salts are left in the soil after the crop has used the water. Most of these mineral salts are beneficial to crop growth and soil condition, but in some cases they may be harmful. Irrigation water quality problems may be caused by (1) total mineral salts accumulating so that crops no …

G77-337 Propagating House Plants, Dale T. Lindgren, Don Steinegger

University of Nebraska-Lincoln Extension: Historical Materials

Propagating house plants in the home is an inexpensive and enjoyable hobby. The home is not always the ideal place, but most house plants can be propagated there satisfactorily with a minimum of special equipment.

Methods of Propagation

House plants may be propagated asexually, in which all new plants will be identical, in most cases, to the parent plant, or sexually, where the new plants will not necessarily be identical to the parent plants. Plants are propagated sexually by seeds. Cuttings, air-layering, division and runners are asexual methods of propagation.

G75-282 Emergency Wind Erosion Control (Revised March 1992), John A. Smith, Drew J. Lyon, Elbert C. Dickey, Philip Rickey

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide covers temporary techniques for emergency wind erosion control, when time and prior planning don't allow soil or seedlings adequate protection using more desirable methods. Soil erosion by wind is a serious threat to growing crops, our land resource, and the air we breathe. The best solution to soil erosion is long-term planning. Recommended practices include residue or crop cover, strip cropping, and windbreaks. These practices are known to substantially reduce wind erosion in even the most extreme conditions. However, conditions sometimes occur when serious soil erosion is imminent or has just begun, and corrective action is required to …

G73-58 Programmed Soil Moisture Depletion: Top Yields With Least Water (Revised), Paul E. Fischbach, Burt R. Sommerhalder

University of Nebraska-Lincoln Extension: Historical Materials

The development of automated irrigation has introduced a revised concept to irrigation water management that will mean savings of water and energy. By not completely refilling the root zone each irrigation, soil moisture storage capacity is left within the root zone to take advantage of any rainfall that occurs after an irrigation. Conservation of water is important because supplies are being depleted in many areas.

G73-66 Mound Design For Feedlots, Paul Q. Guyer

University of Nebraska-Lincoln Extension: Historical Materials

Shaping each feedlot pen to minimize mud problems is an important part of feedlot design.

Mud is our most costly weather hazard. Shaping each feedlot pen to minimize mud problems is an important part of feedlot design. While mud cannot be eliminated, proper shaping can reduce the number of days when it is a profit robber. And, proper shaping will also reduce the number of fly breeding areas within the pen, adding to summer comfort and gains. The cost is minimal at most locations if shaping is done before installing fencing, bunks, waterers and aprons.

G73-2 Fertilizer Management For Alfalfa (Revised August 1977), Delno Knudsen, George Rehm

University of Nebraska-Lincoln Extension: Historical Materials

Adequate soil fertility is necessary for alfalfa production on both dryland and irrigated soils of Nebraska. With adequate, but not excessive fertilizer programs, irrigated alfalfa should produce 6 to 8 tons per acre. Dryland alfalfa on the same soils should, on the average, produce 2 to 3 tons per acre.

This NebGuide covers the following areas for fertilizer management for alfalfa: soil and water tests, lime, fertilizer for establishment, phosphorus, potassium, sulfur, micronutrients, nitrogen recommendations and special problems.

Bromegrass Production In Nebraska, A. L. Frolik, L. C. Newell

Nebraska Agricultural Experiment Station: Historical Circulars

A native of the old world, from central Europe to China, bromegrass was introduced into the United States about 1884. In 1899, the Nebraska Agricultural Experiment Station reported that "all things considered, it is the most promising cultivated pasture grass for this state that has been tested on the Station farm." Early records of the Station show that considerable seed was distributed to farmers during the period from 1898 to 1902. A few of these early plantings are still in existence. Bromegrass increased in popularity in Nebraska until about 1910. Very little interest was shown in this crop during the …

Ec38-118 Soil And Moisture Conservation In Nebraska, D.L. J. Gross, E.H. Doll

University of Nebraska-Lincoln Extension: Historical Materials

When the white men first explored Nebraska, they found little erosion taking place. They found the hills, particularly in eastern Nebraska, covered with a dense growth of grass, underlain with a thick mat of decaying debris. The valleys were even more densely covered with the water-loving grasses and sedges. The soil underneath the prairie was black and spongy, the result of centuries of accumulating humus. The valleys bordering the streams were boggy and abounded with springs. Clear water flowed constantly in the streams. The upland draws in the more favorable parts of the state were heavily covered with the big …
