Soil pH
What does this map mean?
Soil pH has a significant impact on nutrient availability, microbial activity, nematode populations, soil herbicide efficacy and much more.
| Relative yields at various pH levels | |||||
|---|---|---|---|---|---|
| Crop | pH 4.7 | pH 5.0 | pH 5.7 | pH 6.8 | pH 7.5 |
| Corn | 34% | 73% | 83% | 100% | 85% |
| Soybeans | 65% | 73% | 80% | 100% | 93% |
| Wheat | 68% | 76% | 89% | 100% | 85% |
How can this map be used?
Lime can be applied using a truly precise pH map. For years, university research has reported that 2 ½ ac (1 ha) grids are not as precise as growers have expected. Overlaying those grids on Veris pH maps confirms those findings, on every field. Managing high pH areas is equally important for precise applications of gypsum, sulfur, or iron.
Sensor data quality is high, with a pH reading on every acre (user-selectable).
Zones of contrasting soil are clearly evident, even in viewing raw sensor data maps.
