Curious about a lack of plant growth under her family's evergreen trees, Manashree Padiyath of Woodbury decided that an experiment was in order.
Her resulting essay on the subject, "Greening Under the Evergreens: A Biochar Soil Amendment Study," is now a national award-winner.
Padiyath, a seventh-grader at Math and Science Academy, a Woodbury charter school, is one of 12 students from across the country to capture a "young naturalist award" from the American Museum of Natural History in New York City.
More than 800 essays were submitted to the museum as part of a national science-based research competition for students in grades 7 through 12.
According to a museum news release, Padiyath wondered whether the fertility of the soil under the back-yard evergreens could be improved with the addition of biochar, which is biomass — wood, leaves or grasses — heated to the point of thermal decomposition.
She planted mung bean seeds in three trays filled with the soil, and added four varieties of biochar. Contrary to her hypothesis, the museum said, the additives did not yield any improvement in soil fertility.
The other seventh-grade winner wrote his essay about the respiratory rate of a brown bullhead catfish.
Padiyath and her fellow award winners will be flown to New York for an awards ceremony and luncheon on Friday, May 29. She will receive a cash award and a behind-the-scenes tour of the museum.
