BIOZ® Diamond 10-0-1 combined with Agrolution pHLow can improve soybean yields and P-use efficiency
Whitewater, Wisconsin

Key Conclusions
- The highest yielding treatments (and most P use efficient) resulted from the combinations of Agrolution pHLow and BIOZ® Diamond.
- Agrolution pHLow 11-45-11+2Zn resulted in greater P use efficiency as a starter fertilizer.
- BIOZ® Diamond 10-0-1 consistently increased soybean grain yield across both years of the trial at this location.
- BIOZ® Diamond resulted in similar yield responses regardless of being used alone or in combination with a starter fertilizer (average of 4 bu/A).
Objective
To evaluate the performance of Agrolution pHLow® 11-45-11+2Zn as an in-furrow starter fertilizer for soybean production in comparison to a grower standard practice of ammonium polyphosphate (10-34-0). Also, to understand the additive effect of a nitrogen fertilizer with microbial food – BIOZ® Diamond 10-0-1.

Treatments
- A grower standard rate of ammonium polyphosphate (10-34-0) was applied in-furrow at 3 gallons/A, providing approximately 11.9 lb P2O5/A.
- Agrolution pHLow 11-45-11+2Zn at either 6 or 12 lb/A of dry product was solubilized into 3 gallon/A of water as a carrier. These rates provided 2.7 and 5.4 lb P2O5/A, respectively.
- Agrolution pHLow 11-45-11 +2Zn is an all-in-one water-soluble package for use as an acidifying starter fertilizer to improve phosphorus and micronutrient availability.
- BIOZ® Diamond 10-0-1 was applied at 1 quart/A, either in combination with the three starter fertilizer sources, or as an individual treatment.
- BIOZ® Diamond is a nitrogen fertilizer with microbial food.
- All in-furrow application treatments were compared to an untreated control which received no starter fertilizer or BIOZ® Diamond 10-0-1.
- Treatments were replicated four times in each year.

- Treatments were replicated four times in each year.
Results
- Averaged across two years, starter fertilizer treatments (with no BIOZ® Diamond 10-0-1) increased grain yield over the untreated control by approximately 4.1 bu/A.
- Although the rates of Agrolution pHLow 11-45-11+2Zn used in this study provided less P compared to the grower standard rate of ammonium polyphosphate, greater yield responses occurred, which suggests greater P use efficiency and potentially greater crop safety compared to ammonium polyphosphate.
- Efficiencies were 1.3 and 1.2 bushels of yield increase per pound of P2O5 for the 6 and 12 lb/A rates of Agrolution pHLow, respectively, compared to only 0.2 bushel of yield increase per pound of P2O5 for ammonium polyphosphate.
- BIOZ® Diamond applied as an individual treatment was significantly greater (4.7 bu/A) compared to the untreated control. When combined with a starter fertilizer source, the additive yield benefit of BIOZ® Diamond averaged 3.7 bu/A compared to starter fertilizer alone.
