This alfalfa field was stunted and yellow in areas of high pH soils. There were lime deposits in these areas and are high fixing soils. Plant analysis showed very low phosphorus levels and plant symptoms were that of phosphorus deficiency.
After the first cutting we applied 5 tons/acre of NutraBio (Biomass). This is equivalent to about 150 lbs of phosphorus and 350 lbs of sulfate sulfur in the form of gypsum. The field received over 10 inches of rain in the next three weeks. The alfalfa responded very well. Part of the field was also treated with elemental sulfur. Where the NutraBio was applied the alfalfa showed a significant response during the second cutting. The sulfur and biomass together also showed a nice response, but the elemental sulfur alone gave no response.
