Little River, TX | Check with your friendly Lab and find what stage or stages they recommend for sampling.
It is a good chance the information will be too late for the current crop year but of use the next time you have grain in that field.
An on the go protein tester would be an interesting tool. Problem is NIR needs to be calibrated or it will tell stories.
Plant analysis is the only accurate method to determine the level of the micro nutrients, the crop is finding.
It is also a better for N, P, K, Mn, & Ca. A whole lot better than soil test for nitrogen as most test only looks at nitrate.
It is not unusual for a soil test to say P or K is at acceptable levels and the plant analysis says it is not finding this to be true.
I have seen soil test that reported very low levels of phosphate but the plant analysis showed it to have a strong presence. There are a lot of interactions that the Ph.Ds can only guess at. It is a real mystery using a 52 year old Ag Degree from a State Teachers College. | |
