Soil amendments

An agricultural amendment is a product applied to the soil in order to regenerate or improve its physical, chemical or biological properties, with the purpose of its fertility and therefore, the increase of crop yields and quality.

There are amendments to increase the Cation Exchange Capacity (CEC); that is, to increase the availability of nutrients for plants; others, that correct the physical structure of the soil, favoring percolation and aeration and therefore, promoting better root development; there are also amendments that increase moisture retention in light or sandy soils or level the pH, benefiting the development of microbiology; others, that balance the content of antagonistic elements or sequester toxic elements such as aluminum, iron, manganese or heavy metals.
