Statement of Problem |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
We would like to compare the pH results of the Veris pH meter versus
2.5 acre grids and composite soil sampling using laboratory analysis. |
|

Project Objectives |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
To determine the most cost-effective sampling method from which we can
make management decisions about lime application on no-till soils. We
will compare composite samples, grid samples and Veris results on
sandy loam and loamy sand soil types. |

Methodology |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Using the Veris pH/CEC machine, 80 acres will be measured. The entire
¼ Section will be composite sampled and grid sampled. The Veris
machine will of course only give a pH reading, but all other samples
will be analyzed for pH, buffer pH, O.M., NO3, P, K, S, Zn. While all
of these nutrients will not benefit the liming decision, we felt it
was wise to test for them since we are going to have so much labor
involved anyway. Results will be statistically analyzed and compared.
If possible yield map data will be collected to overlay and compare to
other values to develop correlations and to help determine
profitability of each method. The field being studied had 2-ton,
1-ton, & 0-ton Ag Lime Strips applied in November of 2000, which will
help provide variability in the pH and help determine the most
profitable liming rates for these soils. Planned crop is dryland milo
on 30” rows. |

Expected outcome / Benefit to KARA |
|
|
|
|
|
|
We expect to learn which sampling method is most profitable to
producers, and how accurate the Veris pH meter is on very sandy soils.
KARA members would have first benefit from that information. |
