Using Evapotranspiration Reports for Center Pivot Irrigation Scheduling
by Mahbub Alam Danny H. Rogers
L915
Determine total crop water use since last update of soil water status; Determine rainfall & irrigation amount since last update; Update soil water status; Begin irrigation when needed.Revision Date: Jun 2003
Estimating Manure Nutrient Availability
by Dale F. Leikam Ray E. Lamond
MF2562
Managing manure for efficient crop production, while minimizing potential environmental concerns, is more complex than simply disposing of the manure on agricultural lands.Published Date: Jan 2003
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
Best Management Practices for Phosphorus
by Daniel L. Devlin Gary M. Pierzynski Kent A. McVay
MF2321
When excess phosphorus enters lakes and streams, it enhances the growth of algae and other aquatic weeds. This results in eutrophication, which eventually chokes out other life, depletes oxygen.Revision Date: Aug 2002
Filtration and Maintenance Considerations for Subsurface Drip (SDI) Systems
by Mahbub Alam Todd P. Trooien Freddie R. Lamm
MF2361
The filtration unit is the most important component of an SDI system. The major cause of failure is clogging of emitters. Flushing of driplines should be part of routine maintenance.Revision Date: Jan 2002
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
Suspended Solids: A Water Quality Concern for Kansas
by Daniel L. Devlin Kent A. McVay
MF2501
The major source of suspended solids is cropland. Other sources include roadways, ditches, building sites, streambanks, grazinglands, livestock confinement operations, urban areas, and forestlands.Published Date: Feb 2001
Total Maximum Daily Loads
MF2459
If pollutants are found, a state is required to establish a Total Maximum Daily Load. A TMDL is the pollution a water body can receive without violating water quality standards.Published Date: Aug 2000
Phosphorus and Water Quality in Kansas
by Daniel L. Devlin David A. Whitney Kent A. McVay
MF2463
Phosphorus is essential for crop plant growth. It can move into surface waters & cause impairments of normal uses. Phosphorus is primarily a surface water quality problem, not groundwater.Published Date: Aug 2000
Atrazine Herbicide: A Water Quality Concern for Kansas
by Daniel L. Devlin David L. Regehr
MF2461
Atrazine herbicide runoff is entering Kansas surface waters. The maximum contaminant level (MCL) for atrazine had been set at an annual average of 3 parts per billion (ppb).Published Date: Aug 2000
Water Quality Protection: Best Management Practices for Cropland
MF2462
Chart describing best way to control pollutants when using Alachlor, Atrazine, phosphorus, & nitrogen in crop production.Published Date: Aug 2000
Managing to Minimize Atrazine Runoff
by David L. Regehr Daniel L. Devlin Philip L. Barnes
MF2208
Incorporate atrazine into the top 2 inches of soil. Use fall or early spring applications. Use postemergence premix products. Reduce soil-applied application rates.Revision Date: Feb 2000
Vegetative Filter Strip Systems for Animal Feeding Operations
by Joseph P. Harner III James P Murphy Daniel L. Devlin
MF2454
Use grass plots to reduce nutrient runoff into surface water. Plants should have dense crown and root development; rapid top growth to reduce velocity of runoff water & fibrous roots.Published Date: Feb 2000
Irrigation Formulas and Conversions
by Danny H. Rogers Mahbub Alam
MF2404
provides facts and figures of irrigation formulas and conversions.Published Date: Nov 1999
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
