| It would take a very long time to draw those phos. levels down to a reasonable level. I still don't understand or maybe believe that an excess in phos. will reduce crop yields. Are we not hearing the entire story. There are many "staves" in the yield barrel. I think the shortest one needs to be identified to determine what is limiting yield. For instance, pH can greatly effect yield.
Are you sure you didn't get the manure mixed up with the soil analysis? | |
