dc.description | Rice is one of the most cultivated and consumed cereals in the world and plays a strategic role in the agri-food chain. Rice is the main source of carbohydrates for more than half of the world's population and is consumed by people with high and low purchasing power. Understanding the influence of floods on the electrochemical and chemical properties of soils provides necessary information in their management for rice production. With this objective, a review was carried out to understand the electrochemical alterations in soils cultivated with rice under irrigated conditions. Irrigated soils differ widely in their abilities to release ammonium, P, K, Ca, Mg, Fe, Mn, and Zn and therefore an analysis can provide useful information on potential plant nutrient deficiencies as well as on the appearance of Fe toxicity in soils with irrigated rice. Dissolved inorganic nitrogen (DIN) adsorbed on soil colloids plays an important role in the leaching of N from the soil. In general, the review shows that flooded soils affect electrochemical and chemical processes which, in turn, dynamically affect soil fertility. The widespread adoption of the use of low-loss N sources could become a key solution for the future reduction of environmental pollution by N and agricultural N inputs. | es_ES |

dc.description.abstract | El cultivo de arroz figura como uno de los cereales más cultivados y consumidos en el mundo y cumple un papel estratégico en la cadena agroalimentaria. El arroz, es la principal fuente de carbohidratos de más de la mitad de la población mundial y es consumido por personas con alto y bajo poder adquisitivo. La comprensión de la influencia de las inundaciones en las propiedades electroquímicas y químicas de los suelos proporciona información necesaria en su gestión para la producción de arroz países arroceros. Con este objetivo se realizó una revisión para comprender las alteraciones electroquímicas en suelos cultivados con arroz bajo condiciones de riego. Los suelos bajo riego difieren ampliamente en sus capacidades para liberar amonio, P, K, Ca, Mg, Fe, Mn y Zn y, por lo tanto, un análisis puede proporcionar información útil sobre las posibles deficiencias de los nutrientes de las plantas y también sobre la aparición de toxicidad por Fe en suelos con arroz irrigado. El nitrógeno inorgánico disuelto (NID) adsorbido en los coloides del suelo juega un papel importante en la lixiviación de N del suelo. En general, la revisión muestra que los suelos inundados afectan los procesos electroquímicos y químicos que, a su vez, afectan la fertilidad del suelo de manera dinámica. La adopción generalizada del uso de fuentes de N de baja pérdida podría convertirse en una solución clave para la reducción futura de la contaminación ambiental por N y los insumos agrícolas de N. | es_ES |
