| Notes: | ||
| Subsoil nitrate samples to
24 or 36 inches can improve the accuracy of nitrogen recommendations. CEC calculated by cation summation may overestimate true CEC and underestimate exchangable sodium percentage (ESP) in soils. Copper: Yield response to copper fertilization is infrequent. Plant analysis should be used to confirm a deficiency before applying recommended copper. |
