nitrogen (N), phosphorus (P), and potassium (K), but supply organic matter and micronutrients, such as boron, magnesium (Mg), Cu, and zinc (Zn) ( Warman and Termeer, 2005 ). The ratio of N to P tends to be lower in composted biosolids because ≈15% of N is

K. Organic matter was determined by the Tyurin method ( Schollenberger, 1927 ) and NO 3 -N content by reflectometry (RQ plus; Merck, Whitehouse Station, NJ). The Lancaster method ( RDA, 2002 ) was used in determining available P. An atomic absorption

can be extracted by plant roots. This range varies markedly based on soil properties, including organic matter content, texture, and mineralogy. The high surface area and hydrophilic nature of most soil organic matter result in very high total and

distinctively different from highbush blueberry in its ability to withstand high temperatures and lower organic matter soils. Rabbiteye blueberry is relatively high yielding, with commercial yields in the range of 5000 to 8000 lb/acre typical on well

friable, moist loam soil with high organic matter content like those found along the Mississippi River Bottoms area of Illinois ( Swiader et al., 1992 ). Horseradish that is grown on soils with shallow, hard subsoils will often produce low biomass roots of

Aerification and sand topdressing are important cultural practices to reduce thatch and soil organic matter on golf course putting greens ( Christians et al. 2017 ). However, the cost, dulling of mower blades, and disruption of golfers are some of
