Hello Darrin, it might be to early for me to say and I may lack experience to answer that question but I’ll try. I just installed this plot in June-July. I grew a cover crop of sorghum Sudan grass, sunflower, Sunn hemp, okra, and brown top millet. I didn’t use any nitrogen sources. The sorghum made it to about 6-7 ft tall in 5-6 weeks before going to seed. If I had planted earlier I think it would have grown much taller. I don’t know if this explains anything but it’s all I can tell you. After I terminated it I did some amending, mainly adding some lime in the top 3-4 inches. I over applied and it caused some issues this fall including nitrogen. The plants finally grew out of it for the most part and are doing fine now. Soon I’ll re-till the area 8 inches deep which will mix the top four inches of over applied lime with the lower 4 inches where the pH is 6.0. I think it will balance out around 6.4 or so and the next crop won’t experience the problem I created. My hope going forward is to not have to use nitrogen supplements. The soil has been amended with cobalt and molybdenum in order to aid biology in fixing nitrogen which would be on top of the nitrogen the soil can supply from organic matter. This is the idea anyhow.
