AS AGRICULTURAL SOLID WASTE - COMPOSTING Flashcards
wastes resulting from the production and processing of crops and animals or agricultural
products, including manures with at least 20% solids, pruning and crop residues wherever
produced
agricultural solid waste
any item used to improve the compost structure and to increase porosity to allow internal air
movement
bulking agent
weight ratio of carbon to nitrogen
C:N ratio
mixture of an organic waste with amendment(s) or bulking agent(s) in the proper proportions
to promote aerobic microbial activity and growth and to achieve optimum temperatures
compost mix
controlled decomposition of organic matter by micro-organisms, mainly bacteria and fungi,
into a humus-like product
composting
any item added to the compost mixture that alters the moisture content, C:N ratio, or pH
composting amendment
process where fungi digest the carbons not degraded during composting and further stabilize
the nutrients
curing
site where solid waste is finally discharged and deposited
disposal site
solid waste or combination of solid waste which because of its quantity, concentration, or
physical, chemical or infectious characteristics may: cause, or significantly contribute to an
increase in mortality or an increase in serious irreversible, or incapacitating reversible, illness
hazardous waste
shall refer to the liquid produced when waste undergo decomposition, and when water
percolate through solid waste undergoing decomposition; contaminated liquid that contains
dissolved and suspended materials
leachate
interim containment of solid waste after generation and prior to collection for ultimate
recovery or disposal
storage
involves the arrangement of compost mix in long, narrow piles or windrows that are
periodically turned to maintain aerobic conditions
windrow composting
