Site specific soil sampling - also called "precision farming" and "high tech agriculture" - pinpoints the exact place in the field where a sample was taken. • uses information technologies - global positioning systems (GPS) and geographic information system software (GIS) to gather, store, view and analyze soil data |
| Advantages |
|
• potential to reduce input costs • improved profitability and management • record of environmental stewardship • minimize over/under usage of nutrients • can be integrated with yield data for more precise control over inputs for maximum results in the field |
| Grid Sampling |
| Stratford Agri Analysis recommends GPS sampling with a 2.5 acre grid. We believe that grids larger than 2.5 are not accurate enough to make reliable fertility recommendations. At the same time smaller grid size increases the accuracy of test results but the return on production doesn't always justify the extra cost. |
| Method |
|
• a 2.5 acre grid pattern is used • 5 to 6 cores are randomly collected within a 10 foot radius of the grid center and composited as one sample; ie. on a 100 acre field sampled with a 2.5 acre grid there would be approximately 40 samples - each sample would be comprised of at least 5 cores (total of 200 actual soil cores) |
