The constraint of labour shortage resulted in modern heavy machineries which form a hard pan on agricultural field. A subsoiler plough is famous for breaking hardpan and working at higher depths. On overview of effects of subsoiler on field is studied. The subsoiler has better performance on improving soil properties such as bulk density, porosity, strength and infiltration rates. The subsoiling also has its effects on root system of plants positively. The crop yields were seen positive or no correlation on subsoiling. Among the various methods of ploughing, annual ploughing with modified tynes, winged subsoilers are performing efficiently than the conventional one. On an economic point of view, fully irrigated lands and those lands without any hardpan, subsoiling is not recommended. Many crops produced positive outcomes on subsoiling.
