temperatures greater than 65 °C, Karathanos (1999) reported that decomposition of low-molecular-weight sugars (specifically fructose), in addition to the evaporation of water, could occur within the sample. An ASABE standard ( ASABE, 2007 ) recommends that
-N content was estimated. The results were expressed in terms of the amount of decomposed urea-N (mg) per kilogram of soil per hour (mg Urea-N per kg −1 ·h −1 ). The soil NP in short-term incubation was determined with NO 2 − -N production method ( Schinner

crown and had a higher root-to-shoot ratio with sawdust mulch than with black weed mat ( Larco et al., 2013 ). Sawdust mulch insulates the soil from temperature fluctuations and adds organic matter as it decomposes ( Strik et al., 2017a , 2019 ; White
by many organic blueberry growers to increase soil organic matter content and provide additional nutrients. Depending on the feedstock, compost supplies 3% to 10% of the total N during decomposition for several years after application ( Gale et al

with distilled water to a volume of 200 mL. Because the decomposition of mandelonitrile produces both free cyanide and benzaldehyde, a germination assay was also conducted for benzaldehyde. A dilution series consisting of 1, 5, 10, 20, 50, and 100 μ m
yellow sweet clover and hairy vetch decomposition after incorporation. The two techniques provide different information. Whereas the soil sample provides point in time measurements, the ion exchange membrane of the PRS probe integrates plant-available N
