What is the difference between a soil amendment and a soil conditioner?

The distinction between soil amendments and soil conditioners is primarily based on their specific functions within soil management. Soil amendments are materials that are added to the soil to enhance its fertility, supplying essential nutrients to plants. For instance, adding compost or manure is a common practice to enrich the soil with organic matter and improve nutrient content, thus fostering plant growth.

On the other hand, soil conditioners focus on improving the physical characteristics of the soil, such as its structure, aeration, and drainage capabilities. These materials help in loosening compacted soils, enhancing water infiltration, or retaining moisture in sandy soils. Common examples of soil conditioners include materials like peat moss, gypsum, and certain types of compost that specifically target the physical aspects of soil health rather than nutrient content.

By understanding these roles, it's clear that the correct answer accurately reflects the primary purposes of amendments and conditioners in the world of soil management.
