CARNERO LAZO, Greter et al. Agrochemical mapping and distribution of soils on “El Pitirre” farm. cultrop [online]. 2023, vol.44, n.3  Epub 01-Sep-2023. ISSN 1819-4087.

A soil study was carried out at “El Pitirre” farm, belonging to the Science, Technology and Innovation Entity (STIE) “Sierra Maestra”, with the objective of elaborating maps of landscape forms, soils, pH in water, organic matter and assimilable phosphorus and potassium; through the application of a geographic information system. Soil sampling was carried out with an auger at a depth of 0-20 cm, at a rate five-six simple samples to form a composite sample per area. A total of 39 agrochemical plots were prepared as representative of the 100 ha. Chemical analyses were carried out using the analytical techniques employed in the National Institute of Agricultural Sciences soil laboratory. Agrochemical sampling results showed that soils have a slightly acidic reaction, followed by a neutral one; in relation to the organic matter content, medium predominates, followed by low content; and in general, they have low and very low content of assimilable phosphorus and potassium.

Palabras clave : soil fertility; sampling; nutrition.
