Abstract

Nitrogen (N) fertilizers acidify the soil due to nitrification. No-till soils are particularly susceptible to acidification from the lack of mixing of subsurface alkaline products and the tendency to apply N fertilizers at or near the soil surface. As a result, the zone of acidification is typically in the area of fertilizer placement. Calcium-carbonate is a common soil amendment that neutralizes soil acidity. Sugarbeet waste lime, is a by-product of the sugar refinement process and contains approximately 75% calcium-carbonate and phosphorus. Sugarbeet waste lime is readily available to North Dakota producers for use. Sugarbeet waste lime was applied at 0, 2, 4, 8, and 16 tons of calcium-carbonate/acre. All treatments improved soil pH (p-value <0.001) at the 0-3 in depth and reduced soil extractable aluminum (p-value <0.001). Regression analysis divided by the soil buffer pH at the 0-3 in depth produced several statistically significant equations (p-value <0.05). The equations can be used by producers to improve an acid soil pH to a desirable level. Sugarbeet waste lime treatments increased the fall Olsen phosphorus test and decreases both soil extractable aluminum and manganese (p-value < 0.001).
