Scheduling Irrigations by Electrical Resistance Blocks
by Danny H. Rogers William M. Sothers
L901
Water only when it is needed, you can save irrigation fuel, water, labor, wear and tear on machinery, and increase yields. The blocks are installed for one season at several depths.Revision Date: Nov 2001
Sprinkler Package Effects on Runoff
by Danny H. Rogers Mahbub Alam L. Kent Shaw
L903
Low pressure sprinkler packages have become popular since requirements can minimize pumping costs. Lowering pressure and discharge point reduces the wetted area and can cause runoff.Revision Date: Nov 2008
Soil, Water and Plant Relationships
L904
Knowing how plants use water and how soil and water interact can help producers on irrigated farm ground make better management decisions. This publication helps farmers make the most of limited irrigation resources. 8-page, color.Revision Date: Dec 2014
Considerations for Nozzle Package Selection for Center Pivots
by Danny H. Rogers Mahbub Alam
L908
Sprinkler irrigation system design considerations: application rate, depth of application, system capacity, uniformity of application. 8-page.Revision Date: Dec 2008
KanSched2--An ET-Based Irrigation Scheduling Tool
by Danny H. Rogers Mahbub Alam L. Kent Shaw
EP129
KanSched2 is a program designed to help monitor the root zone soil profile water balance and schedule irrigation events on a field using evapotranspiration (ET) data.Published Date: Dec 2007
Soil Water Measurements: An Aid to Irrigation Water Management
by Danny H. Rogers Mahbub Alam
L795
Outlines how soil water measurements can be used in irrigation water management: GRAVIMETRIC SAMPLING, APPEARANCE AND FEEL TEST, TENSIOMETERS, ELECTRICAL RESISTANCE PROBES, NEUTRON PROBE. 4-page.Revision Date: Apr 1998
Irrigation Water Measurement as a Management Tool
by Danny H. Rogers Gary A. Clark Mahbub Alam
L878
Measurement data can help determine irrigation system efficiency, monitor system performance, detect well problems, monitor pumping plant performance, simplify completion of water use report.Revision Date: Aug 2002
Reading Pump And Engine Performance Curves
by Danny H. Rogers Mahbub Alam
L886
Pump curves show the pump’s ability to produce head and capacity, pump efficiency and brake horsepower. The engine performance curve shows proper loading of the engine for fuel economy.Revision Date: Jul 2006
Terrace Maintenance
by Kent A. McVay G. Morgan Powell
C709
Information on how to maintain agricultural terraces with adequate capacity, ridge height and channel width to accomplish soil and water conservation. 8-page, 2-color.Revision Date: Jul 2004
Citizen Science Water Quality Testing Series W-7: Triazines (Atrazine)
by Rhonda Janke Rebecca Moscou G. Morgan Powell
PK13W7
Triazines, including atrazine and simazine, are herbicides used on crops like corn and sorghum. Atrazine has been implicated as an estrogen mimic in the environment.Revision Date: Jun 2006
Citizen Science Water Quality Testing Series W-8: Stream Biology
by Rhonda Janke Rebecca Moscou G. Morgan Powell
PK13W8
Studying small organisms that live in a stream reveals important clues about a stream's health. Low levels of dissolved oxygen indicate that a stream is in poor health.Revision Date: Jun 2006
Citizen Science Water Quality Testing Series W-2: Color, Odor, Temperature and pH
by Rhonda Janke Rebecca Moscou G. Morgan Powell
PK13W2
The four water tests described in this fact sheet are starting points. Color and odor are descriptive. Temperature and pH can have negative effects on water quality.Revision Date: Jun 2006
Citizen Science Water Quality Testing Series W-3: Turbidity/Transparency
by Rhonda Janke Rebecca Moscou G. Morgan Powell
PK13W3
This test measures cloudiness or light-scattering effect of suspended materials in water. Clay, silt,algae and microorganisms will affect the turbidity reading.Revision Date: Jun 2006
Citizen Science Water Quality Testing Series W-4: Nitrogen
by Rhonda Janke Rebecca Moscou G. Morgan Powell
PK13W4
Inorganic nitrogen tests can locate areas of a farm that contribute significant amounts of inorganic nitrogen in runoff or base flow.Revision Date: Jun 2006
Citizen Science Water Quality Testing Series W-5: Phosphorus
by Rhonda Janke Rebecca Moscou G. Morgan Powell
PK13W5
High levels of total phosphorus are routinely found in silt-laden runoff from agricultural fields. Establish grass buffer strips to filter sediment that carries phosphorus.Revision Date: Jun 2006
