Statement of Problem |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
We are concerned if we are applying enough nitrogen fertilizer at
topdress to our winter wheat in Central Kansas. |

Project Objectives |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
This is a continuation of the work we did for a KARA grant in 2004 --
merely adding "site years" to our data base. |

Methodology |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
We will apply a base rate of nitrogen at topdress (winter/spring 05)
to growing winter wheat in the form of UAN (liquid 32-0-0 or 28-0-0)
to various fields using our simple fertilizer rec formula: (wheat
yield goal * 1.8) minus (starter fertilizer) minus (Soil test N) minus
(previous soybean crop (about .5 # N credit per bushel of yield))
minus (any other topdress applications). For selected topdress strips
(sprayer width = 90 feet) we will increase the base rate by 20# N/A.
We will use a AutoTrac equipped sprayer with as applied mapping. All
other cultural practices are to remain the same. After harvesting
with a yield monitor and AutoTrac equipped combine (header = 35
feet), we will select harvest strips for analysis in the base rate
area and the added Nitrogen area. Further analysis will be done based
on KSU researcher's suggestions. |

Expected outcome / Benefit to KARA |
|
|
|
|
|
|
To demonstrate a simple method of doing on Farm research with tools
already available to Precision Ag practitioners. |
