Method of taking soil from Tianfu soil

1. Digging method: select the soil surface with flat terrain or gentle slope, and dig a pit with a depth of 50-60cm. The shape of the pit can be round or square. Pay attention to leave a part of the pit edge to protect the surrounding soil. After selecting the pit location, dig with tools such as shovel, and pay attention to the light action to avoid damaging the surrounding soil environment, so as to take out Tianfu soil.

2. Soil-breaking method: For sandy soil or soft soil, soil-breaking method can be adopted, which is also called "gridding" or "gridding". Choose a piece of ground that needs soil, break the soil with a shovel, and pay attention to the representativeness of the collected samples. It is best to collect multiple Tianfu soil samples from different directions for mixing.
