The sugar then enters the microbial cell and is hydrolyzed further to glucose which is then oxidized to pyruvate. Pyruvic acid in cranberry soil with organic mater undergoes a variety of changes which is determined by pH, redox potentials, osmotic pressure, the available electron acceptors, and the microorganisms present. Since cranberry soil contains a wide variety of microorganisms, the application of organic substance and sugar may be a good practice in a cranberry fertilizer program. K Ag research has shown a positive response to the application to peat bogs. When urea is applied to bogs, they rapidly undergo the following transformation.
Temperature has a marked effect on ammonium released in cranberry soils.
When water is applied continuously for sometime, almost all the mineralogical nitrogen in a soil is converted to ammonia within 5-10 days. This would affect cranberry production if additional nitrogen is not supplemented. We have noticed nitrogen deficiencies in many cranberry bogs at early fruit formation during the 1988 blossom season in central Wisconsin. Yellowing occurs due to loss of mineral and sulfur from the soil. The fixation of nitrogen biologically is a process by which nitrogen gas is reduced to ammonia.
