Loam is a mixture of clay, sand and silt and benefits from the qualities of these 3 different textures, favouring water retention, air circulation, drainage and fertility. These soils are fertile, easy to work with and provide good drainage.

Loam (in geology and soil science) is soil composed mostly of sand (particle size > 63 micrometres (0.0025 in)), silt (particle size > 2 micrometres (7.9 × 10 −5 in)), and a smaller amount of clay (particle size < 2 micrometres (7.9 × 10 −5 in)).

Clay loam is a type of soil characterized by a mixture of clay, silt, and sand particles. It provides a detailed description of soil structure, biological activity, and consistency, aiding in soil interpretation from both geomorphic and agronomic perspectives.

2024年1月1日 · Clay loam is a specific type of soil texture that contains a higher proportion of clay particles compared to other types of loam. According to the United States Department of Agriculture (USDA) soil taxonomy, a soil is classified as a clay loam if it contains 20-30% clay, 30-50% silt, and less than 52% sand.

2025年1月14日 · Most soils are loam, a mix of two or more other types. Clay loam contains 27-40% clay. For soil to count as “pure” clay, it must contain at least 40% clay particles. 1 These clay particles are the smallest of all soil types, measuring less than two one-thousandths of a millimeter, providing a fine, smooth texture. Clay Formation

Most common garden plants prefer loam — soils with a balance of different-sized mineral particles (approximately 40% sand, 40% silt, and 20% clay) with ample organic matter and pore space. However, some plants grow better in sandy soils, while others are well-adapted to clay soils.

2010年3月9日 · A fourth term, loam, is used to describe a roughly equal concentration of sand, silt, and clay, and lends to the naming of even more classifications, e.g. "clay loam" or "silt loam." In the United States, twelve soil texture classifications are defined by the USDA: Clay ( 粘土) Silt （粉土） Sand （砂土） Loam （壤土） Silty clay

2024年5月25日 · Loam is a combination of sand, silt, and clay—the three sizes of soil particles from largest to smallest. While there is a good bit of variability, ideal proportions for most garden plants are approximately 40% sand, 40% silt, and 20% clay .

Dry clay shrinks but stays packed, forming dense clods and cracking the soil surface. These drawbacks can be lessened by adding organic matter over time. Usually clay loam contains a good deal of plant nutrients and supports most types of plants and crops. Clay loams can be improved to create better drainage without too much difficulty.
