The present application relates generally to methods and systems for delivering amendments like sulfate to a subsurface below a ground surface. In one embodiment a process comprises advancing a borehole from the ground surface to the subsurface below the ground surface wherein the borehole is advanced above a water table. The borehole is at least partially filled with a mixture comprising gypsum and a granular media. The borehole is then irrigated with water to at least partially dissolve the gypsum and to spread the dissolved gypsum to a desired treatment zone below the ground surface. The irrigating may comprise employing a gravity fed trickle flow using an irrigation line while the desired treatment zone may comprise one or more hydrocarbons.
