Rapid soil pH mapping

摘要

PRECISIONAGRICULTURE is the first company in Australia to offer a rapid soil pH mapping service. The company imported a pH detector unit from America in December 2010 and mounted it on a Yamaha Grizzly 700 quad bike. Farmers are using the pH maps to better understand lime requirements. Paddocks which measure significant soil pH (water) variability can also have a variable rate lime prescription map generated. The conventional technique for mapping soil pH is using a standard soil sampling probe and sending samples away for laboratory analysis.
