A lawn aerator achieves this by removing small cores of soil. The ½-inch wide and 2- to 3-inch-long soil cores are left on the soil surface, where they slowly break down, replenishing the soil.
Core lawn aerator attachment on a conventional front-tine garden tiller. A lawn aerator is a garden tool designed to create holes in the soil in order to help lawn grasses grow. [1] In compacted lawns, aeration improves soil drainage and encourages worms, microfauna and microflora which require oxygen. [2]
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] Lack of oxygen in the soil can impact plant growth.
Regenerative agriculture is a conservation and rehabilitation approach to food and farming systems. It focuses on topsoil regeneration, increasing biodiversity, [1] improving the water cycle, [2] enhancing ecosystem services, supporting biosequestration, [3] increasing resilience to climate change, and strengthening the health and vitality of farm soil.
The searing heat from wildfires can transform metals found naturally in the soil into cancer-causing airborne particles, according to a new report.. While a growing body of research has focused on ...
Tilling the soil, or tillage, is the breaking of soil, such as with a plough or harrow, to prepare the soil for new seeds. Tillage systems vary in intensity and disturbance. Conventional tillage is the most intense tillage system and disturbs the deepest level of soils. At least 30% of plant residue remains on the soil surface in conservation ...
Mulch suppresses weeds, retains moisture in the soil, and adds nutrients back to the soil, too. "Fallen leaves can be used as mulch around annuals, vegetables, perennials, shrubs, and trees," says ...
Common attributes of soil degradation can be salting, waterlogging, compaction, pesticide contamination, a decline in soil structure quality, loss of fertility, changes in soil acidity, alkalinity, salinity, and erosion. Soil erosion is the wearing away of topsoil by water, wind, or farming activities. [54]
