Definitions

1. Soil structure is the arrangement of soil particles into aggregates.
2. Soil structure is important because it determines the ability of soil to hold and conduct water, nutrients, and air necessary for plant root activity.
3. Soil structure is determined by how individual soil granules clump or bind together and aggregate, and therefore, the arrangement of soil pores between them.
4. Soil structure is considered to be good or bad in terms of its application; plant growth in agricultural settings is one such application.

Soil Amendments

1. The use of soil amendments can also be employed to alter the soil structure and promote the dissolution of the hard pan.

Bare Soil

1. Sowing a green manure on bare soil in the fall can improve the soil structure, prevent nutrient leaching and help with weed problems. (Web site)

Charman

1. Clay type, organic content and soil structure also influence soil water retention (Charman & Murphy 1977).

Cultivation

1. Cultivation, especially with heavy machinery, can degrade soil structure. (Web site)
2. Charman and Murphy (1998) propose two categories of soil structure decline: cultivation and irrigation.

Subsoil

1. They were soil color, organic content, soil structure, drainage, erodibility, and nature of subsoil.

Arrangement

1. Soil structure describes the arrangement of the solid parts of the soil and of the pore space located between them (Marshall & Holmes, 1979).

Formation

1. Physically it helps the soil retain moisture and encourages the formation of good soil structure.
2. Oades, J. M. 1993. The role of biology in the formation, stabilization and degradation of soil structure.

Aggregates

1. Soil structure decline under irrigation is usually related to the breakdown of aggregates and dispersion of clay material as a result of rapid wetting.

Aggregation

1. Aggregation of primary soil particles is a critical determinant of soil structure.

Factors

1. Other factors which contribute to the unique character of German wines, such as soil structure and climate, simply cannot be relocated. (Web site)

Soil Type

1. These products help enhance soil drainage, improve soil structure, boost fertility and prevent drought stress no matter what the soil type.

Water Movement

1. Eventually the mulch breaks down to create humus that improves soil structure, aids moisture retention, and improves air and water movement through the soil.

Pore

1. Cutans are the modification of the soil texture, or soil structure, at natural surfaces (particle, pore, or ped) in soil materials due to illuviation.

Microbial

1. It is where soil structure starts to improve and microbial activity increases. (Web site)

Soil Organic Matter

1. It contains soil organic matter that improves soil structure and soil moisture retention.

Cover Crops

1. The root system of cover crops improves soil structure and helps prevent erosion.

Water

1. Soil structure has a major influence on water and air movement, biological activity, root growth and seedling emergence.

Composting

1. COMPOSTING improves soil structure and moisture retention. (Web site)

Compost

1. Most garden debris can be recycled into compost, which then provides plant foods and improves soil structure.

Crop Rotation

1. Crop rotation can also improve soil structure and fertility by alternating deep-rooted and shallow-rooted plants. (Web site)

Tillage

1. He argues that a combination of no-till for some crops and tillage for others will help reduce both damage to soil structure and use of synthetic chemicals.

Porosity

1. Traditional agricultural practices have generally caused changes in soil structure which have compromised aggregation and porosity.

Voids

1. Soil particles pack loosely, forming a soil structure filled with voids.[2] The solid phase occupies about half of the soil volume.

Organic Matter

1. The soil structure may be improved by the introduction of organic matter such as compost or peat. (Web site)
2. It contains organic matter, that improves soil structure and water retention.

Earthworms

1. The organic material improves soil structure by binding soil particles together and provides food for soil organisms such as earthworms. (Web site)
2. Earthworms improve water infiltration and water holding capacity because their shredding, mixing, and defecating enhances soil structure. (Web site)
3. Microbial exudates act to maintain soil structure, and earthworms are important in bioturbation. (Web site)

Soils

1. Soil structure and microbial habitat are central to functioning of soils.

Soil

1. It also adds organic matter to the soil which may improve soil structure, aeration, soil moisture-holding capacity, and water infiltration. (Web site)
2. Increased soil organic matter enhances soil structure, as well as the water and nutrient holding and buffering capacity of soil (Patrick et al.
3. Soil structure There is growing realisation in the farming world that soil has a natural structure which can be damaged by tillage. (Web site)

Soil Structure

1. Earthworms dramatically alter soil structure, water movement, nutrient dynamics, and plant growth. (Web site)
2. Rebuilding is especially possible through the improvement of soil structure, addition of organic matter and limitation of runoff.
3. Soil color, soil structure, and soil texture are especially important components of soil morphology.
