“…Additional research is needed to identify consistent systems that provide responses to DDGs as a fertilizer source in low and medium yield environments if the cost of DDGs is low enough to be used as a fertilizer source for corn. This may require management changes, such as supplemental synthetic N fertilizer applications at reduced rates (N' Dayegamiye, 2006;Rashid & Voroney, 2005;) or incorporation (McDade & Christians, 2000) to achieve yields similar to conventional N fertilizer sources.

Increased ethanol production may result in excessive dried distillers grains (DDGs) that could be utilized as a fertilizer source for corn (Zea mays L.). Research was conducted to evaluate the effects of 1) DDG rates on weed suppression, changes in soil properties, and differences in grain yield and quality and 2) DDGs, polymer-coated urea (PCU), and anhydrous ammonia (AA) fertilizer sources on grain yield and quality. DDGs had a total N-P-K composition of 38.2-6.9-11.5 g kg -1 , respectively. There was no corn injury, common cocklebur or jimsonweed control with DDG rates up to 3600 kg ha -1 . Corn grain yield increased 1.41 and 1.56 kg ha -1 for every kg ha -1 of DDGs applied in medium and high yield environments, respectively. Grain yield was ranked non-treated control < DDGs < AA = PCU when fertilizers were applied at N equivalent rate of 140 kg ha -1 in medium and high yield environments.

“…The N requirement by sweet sorghum depends on the initial fertility of the soil (Tamang, 2010). Excessive N fertilization can diminish the soluble carbohydrates in sweet sorghum (Almodares et al, 2009), reduce profits for farmers, and harm the environment (Bolck, 1984;Rashid & Voroney, 2005). N can be lost by volatilization once applied to plants, and the resulting nitrous oxides (N 2 O) are potential greenhouse gas sources (Crutzen & Ehhalt, 1977;Ruser et al, 1998;Stehfest & Bouwman, 2006;Crutzen et al, 2007).…”

The objective of this research was to determine the optimum nitrogen fertilizer rate for producing sweet sorghum (a promising biofuel crop) juice, sugar, and bagasse on silt loam, sandy loam, and clay soils in Missouri. Seven nitrogen fertilization rates were applied, ranging from 0 to 134 kg N ha À1 . Regardless of the soil and year, the juice content of sweet sorghum stalk averaged 68.8% by weight. The juice yield ranged from 15.2 to 71.1 m 3 ha À1 . Soil and N rate significantly impacted the juice yield (P < 0.0001). The pH and the density of the juice were not affected by the soil or N. The sugar content (Brix) of the juice varied between 10.7% and 18.9%. N fertilization improved the sugar content of the juice. A negative correlation existed between the sugar concentration and the juice yield. In general, the lowest sugar content was found in the clay soil and the impact of the N fertilization on juice sugar content was most pronounced in that soil. The juice sugar yield ranged between 2 and 9.9 Mg ha À1, with significant differences found between years, N rates, and soils. N fertilization always increased the sugar yield in the clay soil, whereas in loam soil, a significant sugar response was recorded when the sweet sorghum was planted after corn. The average juice water content was 84% by weight. The dry bagasse yield fluctuated between 3.2 and 13.8 Mg ha À1 with significant difference found with N rate, soil, and year. When sweet sorghum was grown after soybean or cotton, its N requirement was less than after a corn crop was grown the previous year. In general, a minimum of 67 kg N ha À1 was required to optimize juice, sugar, and bagasse yield in sweet sorghum.

“…With the increase in corn acreage as a result of increasing ethanol production, the use of N will likely increase. If the balance between nutrients removed and those applied through fertilization is not carefully maintained, environmental and soil productivity problems may occur (4,23,28,34). Nitrogen management is therefore important not only to optimize profit, but also to sustain the biofuel production system.…”

Impact of Nitrogen Fertilization on Nutrient Removal by Corn Grain

2011

Nitrogen fertilization and nutrient removal are some of the greatest challenges associated with the production of bioethanol from corn grain in the United States. The project was conducted in Missouri from 2008 to 2009 in a silt loam soil to determine the effect of N fertilization on the nutrient removal by corn grain. Corn grain removed 31 to 201 kg N/ha, 10 to 102 kg K/ha, 3 to 20 kg P/ha, 0.6 to 11 kg Ca/ha, 0.7 to 2.7 kg Fe/ha, 0.045 kg Mn/ha, and 0.003 kg Cu/ha, depending on the N rate. Our results suggest that as farmers add N to their soil to improve the grain or starch yield, they will also be increasing the nutrient removal, therefore affecting the fertility of their fields if the nutrient removal is not offset.
