What is the purpose of this presentation? n Provide a better understanding of site specific yield information and the value that it can bring to your farming operation.

How are we going to accomplish this purpose? n Look at a raw yield map n Show the different type of information that is collected. n Show the different maps that we can make. n Look at how we can compare multiple years worth of data n Look at the exiting new Statistical Analysis Tool

Raw Yield Data

Moisture Data

Elevation Data 26 feet difference

Contoured Yield Map

Normalized Yield Map

Spatial Compositor Tool Allows you to layer several layers of data and then graph the correlation between two variables

Field A n 97.3 Acres n Fairly uniform soil type n Grid Soil Sampled in the fall of 1999 n Corn in 1999 n Variable Rate Applications of Lime and Fertilizer in the Fall of 1999

Field B n 20.2 Acres n Slightly Variable Soil Type n Grid Soil Sampled in the fall of 1998 n Variable Rate Applications of Lime and Fertilizer in the Fall of 1998 n Soybeans in 1999

Field C n 38.3 Acres n Variable Soil Types n Grid Soil Sampled in the fall of 1998 n Variable Rate Applications of Lime & Fertilizer in the fall of 1998 n Soybeans 1999

Summary n The information generated from yield data and grid soil sampling can add value to your farming operation by providing response curves for different situations.
