Soil Structure. In subject area: Agricultural and Biological Sciences. Soil structure is the spatial arrangement of solids and pores at scales smaller than the soil horizon, and consists of clusters of solids and pores called aggregates, that have hierarchical, emergent properties, and memory that define their functions. From: Geoderma, 2023.

For soil used in agriculture, a ‘well-structured soil’ will have a continuous network of pore spaces to allow drainage of water, free movement of air and unrestricted growth of roots. Typically, a ‘good’ agricultural soil is thought to consist of around 50% solids, 25% air and 25% water, but this will vary according to soil type.

Knowing the soil in which you grow your plants is extremely important, especially if you grow them in large amounts or for financial reasons. Indeed, plants (if not for hydroponic growth) develop in the soil through which they “eat” (absorb minerals), drink, and breathe. A bad soil for nutritional or drainage purposes can cause your crop to fail, l...
The accuracy of your soil test depends on how you take soil samples. Here are some basic guidelines: 1. Tools and materials: Use a clean soil probe, auger, or spade to take each soil sample. Prepare resealable plastic bags or containers for storing the samples. 2. Area: Choose an area with similar soil and planting history. 3. Soil depth: First, cl...
Analyze your soil to know if it is suitable for your plants. For best results, take a soil sample of your garden at least once a year. After you identify your soil type, many healthy gardening or planting decisions will follow. Don’t worry. Soil analysis is easy.
What’s this about: In addition to easy soil analysis that you can do yourself, you can also send a soil sample to a soil testing laboratory for more accurate results and more complete information about your soil. Why It’s Important: A laboratory analysis of soil uses chemicals to estimate what and how much nutrients remain available to plants, the ...
Importance: Soil analysis is important in effective gardening as well as in large-scale crop farming. Soil sampling: The proper soil sampling procedure is an important first step in soil analysis. Two methods are described at the start of this article. Soil analysis: There are different ways to analyze soil, each providing different types of inform...
In a well-structured soil, roots can more easily exploit the mass of soil for nutrients and water. Although maintaining a good soil structure is as much a matter of cultivation and soil management as it is of soil humus content, farmers should be encouraged to maintain the humus content of their soils by incorporating available crop residues, including straw, and organic wastes, composts and ...
Jul 29, 2015 · Ideal pore distribution is generally found in a well-structured soil with the majority of small pores within soil aggregates (matrix pores) and large pores between soil aggregates (interstructural pores) (Kimmins 1997). Forest soils contain a larger percentage of organic matter that results in better soil aggregation and porosity; thus, moisture availability in forests is usually greater than ...

Jan 24, 2023 · Soil health is the foundation of productive farming practices. Fertile soil provides essential nutrients to plants. Important physical characteristics of soil structure and aggregation allow water and air to infiltrate, and roots to explore. Soil health and soil quality are terms used interchangeably to describe soils that are not only fertile ...

Jul 9, 2021 · The arrangement and size of aggregates and pores in a soil results in different soils having different types of soil structure. As soil aggregates combine, a soil will form clumps. Other words used to describe soil structure include porosity, tilth and friability. Aggregates. A well-structured soil has a mix of small and large aggregates.
