Soil samples are small amounts of soil collected from a specific location for analysis. They help scientists and farmers understand the soil's composition, including its nutrients, pH level, and organic matter content. This information is crucial for determining the best crops to grow and how to improve soil health. Collecting soil samples involves using tools like a soil auger or shovel to gather soil from different depths and areas. The samples are then sent to a laboratory, where they undergo various tests. Results guide decisions on fertilization, irrigation, and land management practices to enhance agricultural productivity and sustainability.
