e1“A series of laboratory incubation, greenhouse, and field studies were conducted to evaluate fertilizer reaction and Mn sources on availability of Mn to sugarbeets ( Beta vulgaris L.), soybeans ( Glycine max L.) and navy beans ( Phaseolus vulgaris L.)”

Other claims from this paper (12)
- Intervention effect Fertilizer sources producing an acidic reaction initially increased DTPA-extractable Mn in the soil band.
- Intervention effect After seven weeks, H3PO4-extractable Mn levels did not differ significantly among fertilizer treatments.
- Observation DAP-Urea-KCl gave the highest DTPA-extractable Mn after seven weeks among the fertilizer sources, above control.
- Intervention effect Banded MCP was as effective as banded Mn in increasing Mn availability, extractable and to plant uptake.
- Intervention effect Banded Mn along with banded MCP was much superior to either factor alone in Mn availability.
- Intervention effect Nitrogen source and placement had small and variable effects on Mn availability.
- Intervention effect MnSO4 gave higher tissue Mn than the control in field studies on seven soil types.
- Intervention effect MnO (100 mesh) gave higher tissue Mn than the control in field studies on seven soil types.
- Intervention effect Oxysulfate (partially acidulated MnO) did not differ from the control in tissue Mn.
- Intervention effect EDTA-chelated Mn did not differ from the control in tissue Mn.
- Observation The difference in tissue Mn between acidic and basic fertilizer diminished when oxidation of the basic fertilizer was more complete.
- Recommendation Use of an acidic fertilizer with MnSO4 or finely divided MnO would help eliminate early-season Mn deficiency.
