In recent agronomy, tilling is not one of the best farming practices anymore.
Tilling involve digging about a spade deep, and putting the soil back in the ground, but inverting the top and bottom layers.
Both layers contain different sets of organisms, for instance aerobic bacteria that require oxygen in the top soil, and anaerobic bacteria in the bottom layer. You basically kill most of both kinds every time you till.
Tilling is a great mechanical way to get rid of weeds, as they will decompose when put upside down under the ground with no sunlight available, but it is currently viewed as bringing about a few flaws, among which:
More and more American farmers have adopted the "no-till" cultural practice, which consists in leaving the soil as it is after harvest, or maybe planting green manure, and planting the new crop directly in the soil that still has the stubbles of the old crop in it.
However, no-till relies heavily on genetically modified plants that produce their own pesticide in order to reduce the number of tractor passages.
The Fukuoka method of farming is an Organic Gardening method that does not use tillage, but it does not suit intensive organic farming.

Turning the soil over
Tilling the soil is the same cultivating it/ digging it up.

Aeration improves movement of water, oxygen, and carbon dioxide through your soil which is important for not only plant roots, but also for microbes and other soil biota that also help move nutrients around for your plants. But, don't aerate too much with tilling. Tilling increases soil erosion and aslo nutrient leaching.

Soil erosion can be increased by wind, water, or over tilling the land.
