Hecla sandy loam and Embden sandy loam; pH = 7.1; 1.7 % organic matter, soil
N 27 lbs/acre soil K were very high; soil S was high. |
|
|
|
Previous crop: |

|
|
|
|

|
Plots: |
Plots were 40 ft long by 10 ft (4 rows) wide. The study had six replications. |
|
Treatments: |
Trt 1 = check; trt 2 = Bio-Forge 16 oz/acre @ V6
(June 25); trt 3 =
Bio-Forge 8 oz/acre @ V6 (June 25) and Bio-Forge 8 oz/acre @ R1 (July
31); trt 4 =
check; trt 5 = Bio-Forge 8 oz/acre
in-furrow @ planting (May 17), Bio-Forge 8 oz/acre @ V6 (June 25)
and X-Cyte 16 oz/acre; V9 (July 8); trt 6 = Bio‑Forge 8 oz/acre in‑furrow @ planting (May
17), Bio-Forge 8 oz/acre @ V6 (June 25), X-Cyte 16 oz/acre; V9 (July 8)
and Sugar Mover 16 oz/acre @ R1 (July 31). |
|
|
|
Fertilizer: |
Broadcast 9 lbs N/acre, 42 lbs P2O5/acre, 36 lbs K2O/acre, 5 lbs S/acre and 2 lbs Zn/acre. Three lbs N/acre and 10 lbs P2O5/acre in furrow as
