How healthy soil makes for a healthy life commonlit answers? ›

In summary, healthy soils are the foundation for a healthy life. They support the growth of nutrient-rich food, enhance plant productivity, filter water, and contribute to climate change mitigation.

The Soil Health foundation consists of five principles which are: soil armor, minimizing soil disturbance, plant diversity, continual live plant/root, and livestock integration.

Biodiversity loss is threatening the global economy and the world's food supply. We rely on the soil for 95% of food, globally, but a third of it has already degraded, according to the UN.

Healthy soil is teeming with life and nutrients, while unhealthy soil is challenged by erosion, invasive species, and more.

As organisms decompose, their nutrients become food for plants and other organisms. This web is an essential lifeline for all plants to receive nutrition and, in turn, for animals and humans to receive nourishment. Healthy soil also makes clean water and air possible.

Loam: Loam is an ideal garden soil for many types of plants. It's crumbly, full of organic matter, retains moisture, and drains well. For most plants, this is "healthy" garden soil.

The above soil orders in sequence of increasing degree of development are Entisols, Inceptisols, Aridisols, Mollisols, Alfisols, Spodosols, Ultisols, and Oxisols. Histosols and Vertisols may appear in any of the above at any time during their development.

The agricultural plants that often replace the trees cannot hold onto the soil and many of these plants, such as coffee, cotton, palm oil, soybean and wheat, can actually worsen soil erosion. And as land loses its fertile soil, agricultural producers move on, clear more forest and continue the cycle of soil loss.

Putting all the data together, the researchers found continuous corn increased soil organic matter and acidity, and led to an increase in microbes involved in both nitrification and denitrification.

Beyond that… do what works! Yes, generally this means keeping the soil covered with living plants, minimising disturbance to the soil like ploughing, minimising the use of synthetic fertilisers, herbicides, pesticides and fungicides etc etc.

In no-till farming, farmers do not till their fields before planting. Instead, they use specialized equipment to create a channel that is just spacious enough for seeds to be planted, minimizing soil disturbance.

Healthy soils provide many benefits to plants, animals and humans, including nutritious food, better fertilizers, and improved human health. Nutrient-rich soils are essential for the growth of healthy plants, and the nutrients they contain are essential for our own health.

It is commonly said that an ideal soil is 50% pore space (water + air), 5 % organic matter, and 45% minerals. The 45% of the soil that is minerals is the sand, silt, and clay component. Organic matter and soil minerals form organized units, which are referred to as soil aggregates.

Healthy soils provide habitats that support thousands of different species of fungi, bacteria and invertebrates, which then work in combination to drive the Earth's carbon, nitrogen and water cycles, thereby creating the nutrients and food we need to survive.

Well-structured soil is porous and oxygen rich. Life in the Soil Food Web (plant roots, microbes, worms, and more) is further nourished by oxygen. An oxygen-rich environment is also inhospitable to anerobic microorganisms—which thrive in oxygen-poor environments—that cause plant diseases.
