Sciblogs has posted an interview with 18-year-old Kyle Robertson, a former Palmerston North Boys’ High School student who has been squashing soil with a press and pouring fake cow pee on top.
The idea is to model the effect of cow trampling on nitrate leaching and the work has had some surprising results.
In the interview he explains why his Gold CREST research tells farmers to beware of overstocking on sandy loams.
CREST is an international awards scheme designed to encourage years 0-13 students to be innovative, creative, and to problem solve in science, technology and environmental studies.
The interviews of scheme participants are supported by the Royal Society of New Zealand.
