Arcillas: clasificación y problemas que causan en la agricultura

This document deals with what is related to clays, classification and problems they cause in agriculture. Due to the above, it was determined that clays can be classified as primary clays, which are those that are found in the same place where they were formed, that is, they have not been transported by water or wind and secondary clays are those that have been transported from the place where they originated; water is the most common element that transports them, also wind and glaciers do it; These types of clays are much more common and are composed of more elements such as mica, iron, quartz and other minerals from different sources; clayey soils in conditions of high surface humidity are less susceptible to experiencing a decrease in surface roughness associated with the impact of raindrops, especially if the surface roughness of the soil is moderate or low; There is a notorious effect on decreasing the clay content and this is manifested in the rapid decrease in the upper limit of plasticity and the consequent decrease in the number of plasticity; The amount of water retained by a sandy soil and a clay soil is not the same, and in poorly drained soils it is possible to produce certain crops at an acceptable level, provided that the application of lime and an adequate amount of phosphorus to the establishment is considered.

El presente documento trata lo relacionado a las arcillas, clasificación y problemas que causan en la agricultura. Se determinó que las arcillas se pueden clasificar primarias que son las que se encuentran en el mismo lugar en donde se formaron, es decir, no han sido transportadas por el agua o el viento y las arcillas secundarias son las que han sido transportadas del lugar en que se originaron; el agua es el elemento más común que las transporta, también el viento y los glaciares lo hacen; estos tipos de arcillas son mucho más comunes y se componen de más elementos como mica, hierro, cuarzo y otros minerales procedentes de diferentes fuentes; los suelos arcillosos en condiciones de humedad superficial elevada son menos susceptibles a experimentar un descenso de la rugosidad superficial asociado al impacto de las gotas de lluvia, especialmente si la rugosidad superficial del suelo es moderada o baja; hay un notorio efecto al decrecer el contenido de arcilla y es el que se manifiesta en la rápida disminución del límite superior de plasticidad y la consiguiente disminución del número de plasticidad; no es igual la cantidad de agua que retienen un suelo arenoso y un suelo arcilloso y en suelos de mal drenaje es posible la producción ciertos cultivos a un nivel aceptable, siempre que se considere la aplicación de cal y una cantidad adecuada de fósforo al establecimiento.
