"However, co-composting beet vinasse with cotton gin crushed compost beneficially impacted soil properties and increased wheat yield (Tejada, 2006)."
"A number of scientific studies have analyzed the fertilizing efficiency of vinasse. For example, it was found that sugar and cane yields increased with application of vinasse, with the optimal results obtained through application of vinasse at the moderate dosage level of 50,000 L ha–1
Further, the N (nitrogen), P2O5 175 (phosphorus) and K2O (potassium) sugarcane demands were supplied at this dosage level in proportions of 55%, 72%, and 100%, respectively (Gómez, 2000). It was also observed that application of vinasse to
sandy loam soil enhanced the organic carbon, available nutrient levels, and the microbial soil population, thereby resulting in higher sugarcane yields (Baskar, 2005). This report also suggested that application of distillery effluent 40–60 days prior to planting may overcome any issues with the excessive BOD of vinasse.
The application of fresh beet vinasse had a detrimental impact on the soil’s physical, chemical, biological properties and wheat yield parameters, most likely because high quantities of sodium and fulvic acids were introduced into the soil by vinasse. However, co-composting beet vinasse with cotton gin crushed compost beneficially impacted soil properties and increased wheat yield (Tejada, 2006)."
