Petrovsky District is on the western border of Tambov Oblast, with Lipetsk Oblast to its west. It is about 50 km west of the city of Tambov, and 100 km north of Voronezh. Through the district runs the Matyra River, a tributary of the Voronezh River, and part of the Don River basin. The terrain is flat and gently rolling steppe.[8] The black soil of the district supports agriculture, and there are deposits of limestone and other minerals in the area.
The district is about 60 km long and 30 km wide. The administrative center of the district is the city of Petrovskoye. The Lipetsk-Tambov highway runs across the middle of the district. Subdivisions of the district include 12 rural settlements.[8]

Annual precipitation is 450–500 millimeters (18–20 in).[8] The climate is Humid continental climate, cool summer, (Dfb). This climate is characterized by large swings in temperature, both diurnally and seasonally, with mild summers and cold, snowy winters.

History
The area was settled by Slavs at least as early as the 11th century in the village Yablovontsky. The central village of Petrovsky was founded in the late 18th century. In 1868, the South East Railway was laid through the district, on which the Izberdey train station was built. During WWII, Petrovsky District sent 25,000 soldiers to the front. According to the district's website, more than half did not return. The farmers of the district raised funds for a tank column.[11]
