Dr Tim Weaver is a Research Officer with NSW DPI and based at the Australian Cotton Research Institute at Narrabri. Tim joined the Department in 1998 and has worked on a range of projects related to soil quality, soil drainage, profitability and crop rotations in cotton farming systems at the Narrabri institute. Tim has experience in minimum tillage systems and stubble retention systems in irrigated cotton farming systems. Tim completed a PhD in 2013 on estimating deep drainage and the movement of salt, nutrients and pesticides in Vertosols. Tim's research is focussed on crop nutrition in northern NSW.
