| dc.description | SUMMARY This document deals with what refers to soil contamination by herbicides does not cause effects on rice productivity. Rice cultivation is one of the main short-cycle products that are grown in our country, and that serve to meet the demand in food. From what was analyzed, it was determined that the impurities, present in several herbicides, also promote soil contamination, remaining for many years and causing the natural degradation of other pesticides, such as fungicides; the continuous entry of herbicides into the soil and plants, cause detrimental effects on soil microorganisms and their activity, which causes modification of the biological processes essential for the productivity of rice cultivation; the indiscriminate use of herbicides with high doses causes soil degradation; the herbicides Glyphosate and Atrazine, since the time of the Green Revolution, are considered to be the ones that cause the greatest damage in edaphoclimatic pollution; the persistence and dispersion of herbicides in the rice crop soil depends on the soil characteristics and climatic conditions; the agrochemicals used as Glyphosate Bispiribac, can considerably impact the organisms that are in charge of the decomposition of the soil and that serve to increase the productivity of the rice crop; the components that deteriorate the soil due to the use of herbicides are erosion by water and wind. These phenomena that cause in situ degradation of the soil, can be physical or chemical degradation processes and the effects of soil contamination by herbicides is the loss of biodiversity, which limits the phase of preparation of the land essential for agricultural development of rice cultivation. | es_ES |

| dc.description.abstract | RESUMEN El presente documento trata lo referente a la contaminación del suelo por herbicidas no causa efectos en la productividad del arroz. El cultivo de arroz es uno de los principales productos de ciclo corto que se cultivan en nuestro país, y que sirven para suplir la demanda en la alimentación. Por lo analizado se determinó que las impurezas, presente en varios herbicidas también promueven la contaminación de suelos, permaneciendo por muchos años y causando la degradación natural de otros pesticidas, como funguicidas; la entrada continua de herbicidas en el suelo y las plantas, causan efectos perjudiciales para los microorganismos del suelo y su actividad, lo que causa modificación de los procesos biológicos esenciales para la productividad del cultivo de arroz; el uso indiscriminado de herbicidas con dosis elevada causa degradación de los suelos; los herbicidas Glifosato y Atrazina, desde la época de la Revolución Verde, son considerados los que causan mayores daños en la contaminación edafoclimática; la persistencia y dispersión de los herbicidas en el suelo del cultivo de arroz depende de las características del suelo y las condiciones climáticas; los agroquímicos utilizados como Glifosato Bispiribac, pueden impactar considerablemente los organismos que se encargan de la descomposición del suelo y que sirven para incrementar la productividad del cultivo de arroz; los componentes que deterioran el suelo por el uso de herbicidas son la erosión por agua y viento. Dichos fenómenos que originan una degradación in situ del suelo, pueden ser procesos de degradación física o química y los efectos de la contaminación del suelo por herbicidas es la pérdida de biodiversidad, lo que limita la fase de preparación de la tierra indispensable para el desarrollo agrícola del cultivo de arroz. | es_ES |
