Soil correction or rectification is a process that aims to improve the appropriate physical-chemical conditions to maintain a stable, aerated, absorbent agricultural soil, with a high water retention capacity and that allows the ideal development of roots "Root (botany)").

A soil conditioner is a material added to soil to improve plant growth and health. A conditioner or a combination of conditioners corrects soil deficiencies in structure and nutrients necessary for plant growth, among others.

Contenido

El tipo de acondicionador a agregar depende de la composición del suelo, del clima, y el tipo de cultivo. Algunos suelos carecen de nutrientes necesarios para el crecimiento vegetal, otros retienen demasiada o muy poca agua. Los acondicionadores pueden ser incorporados al suelo o aplicados a la superficie, para corregir estas deficiencias.

Materials

Lime is used to reduce the acidity of soils. Fertilizers such as peat, manure, aljez or compost add nutrients to depleted soils. The inoculation of microbes that promote nitrogen fixation, as legumes do naturally, helps fertilize soils.

Porous materials such as diatomaceous earth or sand reduce water retention in clay soils. Vermiculite, hydrogel, bark or clay, on the other hand, will cause the soil to retain more water.

Gypsum is used to correct alkaline, saline and sodic soils.
