What do interconnected pores in the soil profile allow to enter the soil from the surface?

Interconnected pores in the soil profile play a crucial role in the movement of water and air into the soil from the surface. These pores create a network that facilitates the infiltration of water during precipitation or irrigation, ensuring that moisture reaches the root zone of plants. This process is vital for maintaining soil moisture levels, which in turn supports plant growth and agricultural productivity.

Additionally, these interconnected spaces allow for the exchange of gases between the soil and the atmosphere. As air enters the soil through these pores, it provides essential oxygen to plant roots and soil microorganisms, which is critical for respiration processes. Simultaneously, carbon dioxide produced by roots and soil organisms can escape back into the atmosphere through the same network of pores. Thus, the presence of interconnected pores significantly enhances the soil's capacity to absorb air and water, contributing to the overall health of the ecosystem.
