The second round of the Coalition Government's Smart Farming Partnerships is open.
Agriculture Minister David Littleproud said the grants would be available to farmers, Landcare Groups, universities and others.
"We are funding substantial projects between $250,000 and $4 million that improve the sustainability of Australian agriculture," Mr Littleproud said.
"These grants fund sustainable agriculture by helping create new practices and then having farmers use those practices.
"We're looking for applications from across all agricultural industries including cropping, livestock, mixed farming, rangelands, marine, horticulture and sugar.
"Grants can fund research, trials or delivery of projects which deal with, for example, soil health, pest control, farm input efficiency, Indigenous involvement and climate adaptation.
"These grants are delivered in partnerships and offer a fantastic opportunity for organisations to partner with farmers to promote the best practices.
"Those with ideas which promote sustainable farming should apply for these grants.
