Animals contribute to soil aeration from "summary" of Soil, Grass, and Cancer by André Voisin
One of the key benefits of having animals on the land is their ability to improve soil aeration. This process is crucial for maintaining healthy soil structure and promoting the growth of plants. When animals graze on grasslands, they compact the soil with their hooves. This compaction creates small channels and spaces in the soil, allowing for better air circulation and water infiltration. As a result, the soil becomes more aerated, which is essential for the growth of beneficial soil microorganisms and plant roots. In addition to compacting the soil, animals also help to break up compacted soil layers through their movements. As they walk and roam around the pasture, animals loosen the soil, making it easier for air and water to penetrate the ground. This improved soil structure not only enhances aeration but also helps to prevent soil erosion and runoff. By allowing for better water infiltration, animals contribute to the water retention capacity of the soil, which is crucial during dry periods. Furthermore, animals play a role in the decomposition of organic matter in the soil. Their droppings contain nutrients that enrich the soil and feed soil organisms, leading to increased microbial activity. This microbial activity is essential for breaking down organic matter and releasing nutrients that are essential for plant growth. As a result, the presence of animals on the land contributes to the overall health and fertility of the soil.- Animals are integral to the process of soil aeration and soil health. By compacting the soil, breaking up compacted layers, and contributing to the decomposition of organic matter, animals create a conducive environment for plant growth and soil fertility. Their presence on the land is essential for maintaining healthy soils and promoting sustainable agriculture practices.
