The importance of soil fertility

A critical look at industrial agriculture and the role of regenerative agriculture

Soil is much more than just the ground on which we grow our food. It is the basis of life on our planet. But how we treat the soil is crucial: while industrial agriculture relies on intensive exploitation and jeopardises soil fertility, regenerative agriculture shows a way in which we can preserve the soil as a living, regenerative system. This blog post highlights the enormous importance of soil fertility and why a regenerative approach is essential to promote healthy ecosystems and sustainable food production.


Diversity in the soil

Soil diversity is crucial for its health and fertility. Just one gram of healthy soil contains an incredible 8 billion microorganisms, including up to 50,000 different types of bacteria and fungi. These organisms form the so-called edaphon, the totality of all organisms living in the soil. In an untouched forest, the edaphon can reach a weight of around 25 tonnes per hectare. However, interventions such as clearing the forest and converting it into farmland drastically reduce the mass of the edaphon to just four to five tonnes per hectare. This shows how fragile the balance in the soil is and how important it is to protect its biodiversity.

Industrial agriculture: overexploitation of soil fertility

Industrial agriculture, which has become established worldwide in recent decades, is heavily based on monocultures and the intensive use of chemical fertilisers and pesticides. Although this has led to higher yields in the short term, the long-term effects on the soil are catastrophic:

  • Loss of nutrients: Intensive cultivation systems deplete the soil. Monocultures and the use of artificial fertilisers may promote rapid plant growth, but in the long term they lead to the loss of essential trace elements in the soil. Chemical fertilisers often only provide nitrogen, phosphorus and potassium, but neglect the many nutrients required for a healthy ecosystem.
  • Erosion and land degradation: The lack of soil cover, especially in times when no crops are grown, exposes the soil to erosion by wind and water. In recent decades, we have seen significant losses of fertile soil worldwide, as industrial agriculture often leaves the soil unprotected.
  • Soil as a dead substrate: A healthy soil consists of a living ecosystem with billions of microorganisms that work together to maintain soil structure and fertility. Chemical pesticides and herbicides destroy these microbes and turn the soil into a kind of dead substrate that can only be kept productive with additional chemicals.

Soil fertility as the basis for regenerative agriculture

Regenerative agriculture is an alternative approach that treats the soil as a living organism and aims to improve its fertility and resilience. It represents a solution to many of the problems caused by industrial practices:

  • Boost biodiversity: Regenerative agriculture favours mixed crops, crop rotation and the integration of livestock farming. These methods promote biodiversity and the development of a healthy soil microbiota. A diverse soil harbours more organisms, which makes it more resistant to pests and diseases.
  • Building humus and storing carbon: Practices such as composting, mulching and planting cover crops increase the humus content in the soil. Humus is not only important for fertility, but also a key to carbon sequestration. Soils rich in organic matter can store large amounts of CO2 and thus help combat climate change.
  • Improve water retention capacity: A healthy soil with a high organic matter content can store water better. This reduces the need for irrigation and helps protect plants during dry periods. Regenerative practices such as no-till also prevent soil compaction and encourage the absorption of rainwater, reducing flood risks.

A comparison of approaches: Why regenerative agriculture is the future

Whilst industrial agriculture focuses on short-term efficiency and yields, it ignores the long-term effects on our ecosystems. The loss of soil fertility, the destruction of microorganisms and the increasing dependence on chemicals create a system that is both ecologically and economically unsustainable.

Regenerative agriculture, on the other hand, views the soil as a valuable ecosystem that needs to be protected and developed. Through techniques such as permaculture, agroforestry and targeted pasture management, the soil is not only preserved but continuously improved. These approaches ensure that the soil remains fertile for future generations.

Final thought: Soil as the key to sustainability

Soil fertility is not just an agricultural issue – it is fundamental to the future of our food security and our planet. By embracing regenerative methods, we can correct the mistakes of industrial agriculture and create a system that nourishes both soil and people. The soil, the foundation of our lives, deserves our attention and care. It is time to promote agriculture that regenerates life, not destroys it.
