This summer a client of ours started a field trial with pumpkins in Southern Arizona. The trial was done at a farm in San Simon, Arizona. The fields are irrigated with drip irrigation. Activated EM•1® was used in conjunction with conventional fertilizer, humate, and micronutrients. Three applications of Activated EM•1® were applied to total 40 gallons in the soil. No product was applied foliarly.
The only difference between the Activated EM•1® plot and the control was the addition of Activated EM•1®. Final yields were 45 boxes per acre on the control and 54.52 boxes per acre on the Activated EM•1®-treated plot. The observations from the soil and plant tissue analysis are as follows:
1. Organic matter increased with Activated EM•1® (from 1.02 on 5/13/10 to 1.25 on 7/26/10)
2. pH decreased with Activated EM•1® (from 7.8 on 5/13/10 to 7.6 on 7/26/10)
3. N-P-K increased with Activated EM•1® (from
Nitrate NO3 36.95ppm on 5/13/10 to 76.35ppm
Phosporous 19.8mg/kg on 5/13/10 to 21.1 mg/kg on 7/26/10
Potassium 44ppm on 5/13/10 to 82ppm on 7/26/10
4. Powdery mildew was less severe with Activated EM•1® use.
