Organic compost with worms, made from agricultural byproducts in the heart of the cloud forest. Nothing is wasted.
I had the wonderful experience today of watching an adult Yellow warbler feed two fledglings while I was walking at Hyper-humus Marsh in Lafayette NJ.
Plinthite (Gr. plinthos, brick) is an iron-rich, humus-poor mixture of clay with quartz and other highly weathered minerals. It commonly occurs as reddish redox concentrations in a layer that has a polygonal (irregular), platy (lenticular), or reticulate (blocky) pattern. See “Soil Taxonomy” (Soil Survey Staff, 1999) for a complete disscussion.
Upper photo: Nodular plinthite. A moist body of plinthite withstands moderate rolling between the thumb and forefinger, and either moist or air dry it will not slake when submerged in water even with periodic gentle agitation. It is firm when moist and hard to very hard when dry, yet can be broken in the hands.
Lower photo: Platy plinthite. This form of plinthite often occurs in association with an underlying aquitard layer that perches water aiding in the formation of an iron enriched zone.
Plinthite irreversibly hardens upon exposure to repeated wetting and drying, especially if exposed to heat from the sun. Other morphologically similar iron-rich materials that do not progressively harden upon repeated wetting and drying are not considered plinthite. The horizon in which plinthite occurs commonly has 2.5 percent (by mass) or more citrate dithionite extractable iron in the fine-earth fraction and a ratio between acid oxalate extractable Fe and citrate-dithionite extractable Fe of less than 0.10.
