SuperCal 98-G, Pel-Lime and Ag Limestone Broadcast on Soybeans, Year 2000 Research Results

SuperCal 98-G, Pel-Lime, and Ag Limestone Broadcast on Soybeans evaluates these products' 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 98-G 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 replicates 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.

Soil Analysis & Plot Layout

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.
