Stonemeal: an excellent alternative to reduce fertilizer usage!

Stonemeal is a technique used to increase soil fertility by reducing the use of chemical fertilizers. The method consists of using the powder of various types of rock in the cultivation soils. Learn more about this practice that is not recent, but is still very current.

Stonemeal’s other names are biomineralization or remineralization.

The stonemeal process consists of the rejuvenation and conservation of soils by adding "rock dust" rich in phosphorus, calcium, magnesium, potassium, and other micronutrients.

Researchers prove the importance of stonemeal to agriculture represents many economic advantages and environmental and productive, especially in corn, rice, cassava, sugarcane, and fruit and vegetables compared to conventional fertilization.

In other words, rocking is the fertilization of the land by the land itself, through natural processes and maintaining production levels with sustainability and preservation of soils.

In the stonemeal process, soil change is made in two levels:

  • Chemical weathering: the process helps to break down the chemical structure of the minerals that make up the rock or sediment (source material). The stones then undergo a kind of decomposition.
  • Physical weathering: means rocks disintegration to flour or sediment, without any chemical alteration of their nutrients.

In other words, this very process is nothing else than a rocks’ grinding through a selective separation of their minerals according to the need.  

The stonemeal technique improves the soil’s physical, chemical, and biological quality, reducing the number of fertilizers used.

Being a continental country, America has one of the most extensive agricultural fields on the planet. It could be even greater if its soils were not so low when it lacks phosphorus and potassium.

Stonemeal belongs to agroecology principles. It allows low cost because it might avoid intensive use of industrialized inseams that compromise watercourses, soils, and atmosphere, causing a tremendous environmental impact.

Raindrops dissolve carbon dioxide, and it reacts with the rocks when it falls, and the remaining compounds go straight to the oceans. These compounds are employed to make shells and corals. Slowly and inevitably, it attracts the CO2 present in the air and retains it for hundreds of thousands of years.

The United States is a great place to develop stonemeal more extensively due to its abundance of rocks with fertilizing properties!

Trading rock flour pays off as long as they are close to big centers!

 

A significant leverage of rock flour is that it remains on the ground and is not taken by rainwater, like chemical fertilizers.

It is necessary to emphasize that the stonemeal technique is seen as a complementary process and not a full replacement process! Ambiental professionals should divulge more this stonemeal process, mainly in remote regions where communication is more difficult.

In short, this "art" of filtering rock nutrients, although not that new, might be an excellent deal for agribusiness without harming the environment!
