Bundarra students have placed first in the state out of 52 schools for their thorough soil investigating skills.
Five stage three students participated in an Department of Primary Industries (DPI) Investigate: Soils, Science and Technology Competition last term.
Bundarra Central School students have had prior success in the annual competition, but managed to take out first place for 2019.
Hayley Azzopardi, Kayley Smith, Maddison Harper, Sarah O'Grady and Andrew Fox were given the task of observing different soils best suited for food production.
Teacher Pam Doak said the project was focused on sustainability and soil awareness.
"The students assessed the characteristics of soils and discussed factors likely to effect plant growth.
"The competition came at a dreadful time of year, just after the Tingha Plateau Bushfire, it was so hot and the soils were like rocks.
"We decided to plant snow peas. So the students planted them, recorded growth and watering habits and after about five weeks they tipped them out and measured the roots."
During the time of the experiment students also measured and researched soils in the local district, taking samples and testing pH levels.
Together, the students wrote a conclusion and recommendations of how they could improve soils.
"The students said they learnt a lot and believe they know more about different soil after the competition. I think I do too, it's all very interesting," she said.
Students won $1000 for the school by placing first in the competition open to all NSW stage three students and teachers.
The competition provided students an opportunity to prepare a scientific report that aligned with outcomes from the NSW Science and Technology, English and Geography syllabuses.
Bundarra Central School students and staff were extremely proud of the five students who dedicated extra time to the competition- sometimes cutting into their sport.
