Organic lawns often benefit from over seeding, slice seeding and aeration more frequently due to the importance of a strong root system. Well-maintained organic lawns are often drought-tolerant. If a lawn does need watering it should be done infrequently but deeply. [7]
Core aeration is suitable for heavy clay soils, and spike aeration is more suited to sandy or loamy soils. Powered aerator vs. manual aerator. Powered core aerator in use. Powered aerators employ the power from ground propulsion to drive multiple tines into ground. The machines can aerate a large lawn in a relatively short time (similar to ...
Aeration, also known as core aeration, opens the soil profile and makes way for a thriving ecosystem below the surface of the lawn. A thriving ecosystem leads to strong plant growth.
Aerating just before planting/seeding may promote deeper root growth and thicker turf. [ 62 ] Sodding (American English), or turfing (British English), provides an almost instant lawn, and can be undertaken in most temperate climates in any season, but is more expensive and more vulnerable to drought until established.

Soil aeration is the mechanism of improving the exchange of gases between the atmosphere and soil. Through soil microbial activity and plant root respiration, certain gases such as oxygen will be depleted in the soil, while others, such as carbon dioxide, will build up in the soil. [1]
So plant roots can not penetrate deep into the soil for optimum growth in Alkali soils. When soil is irrigated with low pH / acidic water , the useful salts (Ca, Mg, K, P, S, etc.) are removed by draining water from the acidic soil and in addition unwanted aluminium and manganese salts to the plants are dissolved from the soil impeding plant ...
Many species have long roots that may reach two meters (6 + 1 ⁄ 2 feet) or more into the soil, which can aid slope stabilization, erosion control, and soil porosity for precipitation absorption. Also, their roots can reach moisture more deeply than other grasses and annual plants during seasonal or climatic droughts.
