Interview
Plant growth slowed after a period of time in agriculture. To answer these questions: 1. Soil protocols (soil properties - soil temperature - acidity) 2. Air-air protocol (air temperature-humidity) 3 - The water protocol was used (water temperature irrigation - and conductivity - salinity) 4. Ground cover protocol (plant height measurement) The study concluded that the soil salinity is high because PH = 8.9

Hello. I am Shirley Leow, one of your judges on this interesting and important science project. I have two questions. 1.) Were the charcoal, animal manure and sawdust mixed together and then worked into the soil? I don't quite understand how the sawdust was used or why it might have been chosen. 2.) Where is the comparative data for the soil before your treatment? Is it listed in one of the references? Thank you, Dr. Leow
