SuperCal 98G vs. Ag Lime

SuperCal 98G, Pel-Lime, and Ag Limestone were broadcast on soybeans in fall 1999 to evaluate their ability to enhance soybean seedling vigor, stand establishment and yield response.

SuperCal 98G, Pel-Lime, and Ag Limestone were broadcast on soybeans in fall 1999 to evaluate their ability to enhance soybean seedling vigor, stand establishment and yield response.

An 80 acre field was planted with soybean variety Pioneer 92BO5 (141,000 seeds per acre) with SuperCal 98G at 300 lbs/A, Pel-Lime at 300 lbs/A, and ag limestone at 2,000 lbs/A applied broadcast in 70 foot wide strips, 1,100 feet long. Strips were alternated in six replications and comparisons were tracked throughout the growing season until harvest. The average soil texture in these strips is fine and loamy, with an average CEC of 15 and an average pH of 5.1.

The growing season temperatures were normal with several heavy rains following planting through the months of May and June. The late summer months of August, September and October were dry with ideal harvest conditions throughout late September and October.

The Bottom Line:

With treatment cost approximately the same, SuperCal 98G gave an economic yield advantage over Pel-Lime and ag lime. SuperCal 98G gave a 6.2 bu/A advantage over the control.

To compare rate of growth and stand establishment, the population of plants that had reached the V3 stage 5 days after planting were counted and averaged. At the V3 stage more plants per acre had reached this stage using SuperCal 98G than with the other treatments. This marks an increase over the other treatments; SuperCal 98G positively affected that the rate of growth and stand establishment.

  • Plant population at V3 of treatments vs. the control: 80 acre field 
    • SuperCal 98G at 300 lbs/A gave a 4.7% increase in plant population 
    • Pel-Lime at 300 lbs/A gave a 2.0% increase in plant population 
    • Ag Limestone (CaCO3) at 2,000 lbs/A gave a 1.0% increase in plant population
  • 6 replicates 
  • Harvested with Case 2388 yield monitor equipped combine
