The present mixing apparatus has a tank for holding water, a hopper at the top for passing granular fertilizer down into the tank, a strainer below this hopper and above a mixing chamber in the tank, a reservoir for liquid insecticide or the like at the top of the tank, a manual valve between this liquid reservoir and the mixing chamber in the tank, a motor-driven rotary shaft carrying upper and lower mixing blades inside the mixing chamber in the tank, and a discharge outlet at the bottom of the tank. The motor is mounted at the top of the tank. An upper sealed bearing for the motor-driven shaft is located in the strainer and a lower sealed bearing for the shaft is located near the bottom of the tank. Inside the tank the mixing chamber is defined by a generally funnel-shaped screen of fine enough porosity to retain the granular fertilizer on the inside of the screen. A spray pipe extends across the inside of the screen near its upper end and down across the outside of the screen at one side.
