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)).

2024年8月13日 · Loam soil is a type of soil that is a mixture of sand, silt, and clay. Loam soil holds nutrients and has a texture that retains water long enough for plant roots to access it, yet it drains well. This means that, eventually, the water seeps away so that plant do not rot.

Loam is a type of soil that is primarily made up of sand, silt, and a tiny quantity of clay. Sand, silt, and clay make up roughly 40-40-20% of its mineral content by weight, respectively. However, these ratios can vary to some extent, leading to many varieties of loam soils, including clay loam, sandy clay loam, silty clay loam, and loam.

2024年5月25日 · Creating a loamy soil takes time, but this guide will provide everything you need to know. 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.

根据《国际制土壤质地分类标准》，土壤质地由粘粒clay＜0.002mm、粉粒silt（0.002~0.02mm）及砂粒sand（0.02~2mm）构成，其中粉砂质粘壤土的粒径占比大小为：粘粒（15~25%）、粉粒（45~85%）及砂粒（0~40%）,这样的土壤类型称之为粉砂质粘壤土。

2021年7月14日 · Loam soil is a mineral mixture of clay, sand, and silt. In the right proportions, loam is the ideal medium for growing plants. Its mineral content makes up less than half of the soil,...

2022年10月7日 · Components of loam will contain sand, silt, and clay soil but not the problems. Loam soil will hold water but drain at a rate of about 6 to 12 inches (15-31 cm.) per hour. Loam soil should be rich in minerals and nutrients for the plants and loose enough that roots spread out and grow strong.

2025年3月20日 · Loam soil is a mixture of sand, silt and clay, which provides the ideal environment for plant growth. It is nutrient-rich and holds nutrients well, making it fertile. Loam soil is also well-aerated, which is essential for healthy root growth. The larger sand grains prevent the soil from compacting, which helps oxygen reach plant roots.

2024年7月29日 · Loam soil is a harmonious blend of sand, silt, and clay, resulting in its unique composition and desirable characteristics. This balanced combination allows loam to possess excellent drainage capabilities while retaining adequate moisture for plant nourishment.

2024年6月25日 · Loam is a type of soil that strikes an ideal balance among its three main components: sand, silt, and clay. This well-mixed composition offers a number of benefits for plant growth, making it one of the most desirable soil types for gardeners and farmers alike.
