VFR flight to ZZZ at 4500 ft. Approaching ZZZ; ASOS was monitored; winds favoring Runway XX. Announced position and intentions at 10 miles out; 5 miles out; overhead 500 ft. above pattern; entering left downwind; base and final for Runway XX. Only other radio traffic on frequency was a C172 10 to 5 miles out; also approaching ZZZ for landing.On short final to Runway XX; spotted an Air Tractor; turbine agricultural aircraft; on final to Runway XY. I immediately executed a go around; passed opposite direction traffic approximately 300 ft. laterally and 500 ft. vertically. The Air Tractor smoked his tires to make the turn off to the ramp where the agricultural application facility is located.I re-entered the left downwind for Runway XX and landed; taxied to the ramp; and shut down. Airport ground personnel and I had a discussion about the agricultural aircraft based at ZZZ. He noted that at least two of the aircraft are NORDO; and that there have been numerous traffic conflicts at ZZZ due to their NORDO status and frequent operations. They typically hot load; and depart within 5 minutes of landing; using Runway XY irrespective of wind direction due to its proximity to their facility.This situation is a fatal accident waiting to happen. While I realize that there is no requirement to use radios in Class D airspace; there is also no reason why this operator could not equip his aircraft with a single COMM radio; or even a hand held connected to the pilot's helmet. The combination of NORDO; impatience on the part of the operators; and disregard for standard operating procedures and other airport users indicate a lack of safety awareness.
DA-40 Pilot reported encountering another aircraft landing in opposite direction of normal traffic flow without radio communications.
