plant growth promoting substances, disease and pest suppression, improved physical and chemical properties, and increased nutrient content and availability ( Arancon et al., 2004 ). This has generally been found to be true in Hawai'i as well ( Gurr, 2011
physical and chemical properties of organic soils are dominated by organic matter, even though organic matter is commonly not the dominant component by weight. Organic matter has weight-disproportionate volume, reactivity, and moisture retention compared
slow biodegradability in soil. Bioplastics can be processed on equipment designed for petrochemical plastics, eliminating the need to develop new industrial machinery ( Koeser et al., 2013a ). The advantages of bioplastics are their physical properties
‘Evangeline’ sweetpotato produced acceptable yield compared to ‘Bayou Belle’, ‘Beauregard’, ‘Bonita’, ‘Covington’, ‘NC05-198’, and ‘Orleans’. Microwave and oven-baked ‘Evangeline’ and ‘Covington’ roots were analyzed for chemical and physical properties and
) were applied to all substrates at each irrigation as a result of the water-holding capacities of all substrates were within 7% of each other (data not shown), according to substrate physical property analysis performed on all substrate blends before
, animals, and humans ( Karlen et al., 1997 ; U.S. Department of Agriculture, 2017 ). For the purposes of this survey, we used the term “soil quality,” but we recognize that the term “soil health” is often used or preferred. Physical, chemical, and
. Evans et al. (2010) performed a study of physical properties on the same container types used in this study with annuals and found significant algal and fungal growth on peat pots only after 6 weeks. Plant material, substrate composition, and fertilizer
range of intrinsic physical and chemical properties, categorized by Schrader et al. (2015) , after producing ‘Arizona Sun’ blanket flower in two types of #1 trade gallon [0.75 gal (2.839 L)] bioplastic-based biocontainers and a petroleum-based plastic

). Increased SOM improves soil physical properties such as bulk density and increase available water-holding capacity. Chemical properties, cation exchange capacity, pH, and macro- and micronutrient supplies are also improved ( Ozores-Hampton et al., 2011
