While many tuned in to watch the World Cup to see which team would become the globe’s soccer champs, others watched a competition of a different kind: one that named the earth’s best identifiers of slices of earth.
College students from the United States competed with teams from nine other countries to see who could best interpret soil. America took first and second in the inaugural International Soil Judging Contest. And American contest Tyler Witkowski also won second place overall of 45 contestants.
“Soil and land judging at the high school and college level is a baseline entry for young people to study the land and learn to read the landscape so that they can better manage and protect it,” said Maxine Levin, with the National Soil Survey Center of USDA’s Natural Resources Conservation Service. NRCS is the United States’ premier private lands conservation agency, originally founded to conserve and map the nation’s soils. Levin helped prepare the contest and served as a judge. Read more »
