•Composition:Loam is characterized by a balanced mix of sand (larger particles), silt (medium-sized particles), and clay (smaller particles).
•Proportions:While the exact proportions can vary, loam typically contains around 40% sand, 40% silt, and 20% clay by weight.
•Water Retention and Drainage:The combination of these particles allows loam to hold a good amount of water, preventing it from drying out too quickly, while also allowing excess water to drain away, preventing waterlogging.
•Aeration:The pore spaces created by the different particle sizes ensure good aeration, allowing oxygen to reach plant roots, which is essential for healthy growth.
•Nutrient Holding Capacity:Loam is also known for its ability to hold nutrients, making it a fertile soil type for a wide variety of plants.
•Ideal for Plant Growth:Because of its balanced properties, loam is considered an ideal soil type for most garden plants and crops.
•Variations:While the term "loam" describes a general type of soil, there are variations such as sandy loam, silty loam, and clay loam, depending on the relative proportions of sand, silt, and clay.
