 Help Survey Organic Content of U.S. Agricultural Soils Minimize

Principal research scientist Elham Ghabbour and chemistry professor Geoffrey Davies are directing a National Soil Research Project at Northeastern University (NU) in Boston to measure and monitor the humic (HA) and fulvic acid (FA) contents of U.S. agricultural topsoils (0 – 30 cm). These major, microbially-resistant organic soil components retain water, buffer pH, improve soil texture/permeability and regulate many other healthy soil functions. We are concerned that HAs and FAs are being depleted, leading to poorer soils. Soils may be rebuilt with HAs extracted from such sources as low rank coals that are of no use as fuels. Existing data do not distinguish HAs and FAs from transient soil organic matter such as leaf litter, shards and corn stover. Results from 150 samples indicate widely varied soil HA and FA contents. The NU group needs 1-pound, dried soil samples from U.S. farms and counties. The group will reimburse parcel post costs on request and will published and share results with soil donors on request.

Please send an air-dried 1-POUND sample of a surface (0-30 cm) agricultural soil of your County, with leaves, sticks, rocks, pebbles and obvious trash removed, noting its GPS location, texture and classification (if known). Please indicate on the form below if you have historical data for this soil but do not send the data yet. Please keep a copy of this completed form.
