A soil sample is a small quantity of soil collected from a specific location for analysis. It is used to assess the soil's physical and chemical properties, such as pH, nutrient content, and texture. Soil samples help farmers, scientists, and environmentalists understand soil health and fertility, guiding decisions for agriculture and land management. Collecting a soil sample typically involves using a shovel or auger to gather soil from different depths and locations. The samples are then sent to a laboratory for testing. Results from soil analysis can inform practices like fertilization, crop rotation, and erosion control.
