When is a soil considered healthy?

A healthy soil is considered to be a soil that has a good structure, a good water holding capacity, a good amount of nutrients and a good variety of living micro-organisms. 

Values used to measure soil health include soil depth, root density, water holding capacity, biological activity, presence of nutrients and presence of organic matter. In addition, the soil’s ability to filter and purify water is also an important factor in soil health.

Values for a healthy soil

There are several values and standards used to measure soil health. Some of these include:

  • pH: Soil pH refers to the level of acidity or alkalinity of the soil. An optimum pH for most plants is between 6 and 7;
  • Organic matter: Organic matter is essential for soil health, as it provides nutrients and helps retain water. The percentage of organic matter is considered healthy when it is greater than 5%;
  • Nutrients: Soils should have an adequate balance of nutrients essential for plant growth, such as nitrogen, phosphorus and potassium. A soil with an adequate amount of nutrients is considered healthy;
  • Biological activity: Soil biological activity refers to the quantity and variety of living micro-organisms in the soil. A soil with good biological activity is considered healthy;
  • Erosion: Soil erosion refers to the loss of soil due to the action of water or wind. A soil with low erosion is considered healthy;
  • Structure: Soil structure refers to the way soil particles are bound together. Good soil structure is essential for good drainage and to provide a suitable environment for plant roots.

Each of these values has a range considered ideal for a healthy soil and their variation may depend on soil type and use.

Healthy soil is synonymous with good agriculture production

Healthy soil is essential for sustainable and productive agriculture. Because healthy soil provides ideal conditions for plant growth, which in turn can improve crop productivity. 

In addition, healthy soil can help retain water and nutrients, which can reduce the risk of drought and crop failure due to lack of nutrients.

Healthy soil can also help reduce the use of fertilisers and pesticides, as plants will be better equipped to resist diseases and pests. In addition, healthy soil can help improve water quality and biodiversity by maintaining a healthy ecosystem.

In addition, healthy soil is essential for sustainable agriculture, as it allows for long-term agricultural production without degrading natural resources and without causing damage to the environment.

In conclusion, healthy soil is essential for sustainable and productive agriculture. Healthy soil provides ideal conditions for plant growth, improving crop productivity and helping to retain water and nutrients. 

Because, healthy soil can help reduce the use of fertilisers and pesticides, improve water quality and biodiversity, and is essential for long-term sustainable agriculture. 

It is important for farmers and authorities to set goals and strategies to improve and maintain soil health, as healthy soil is fundamental to ensure food security and a healthy environment.
