It is known that soil texture does not change easily, but the effect of soil tillage, soil fragmentation and the passage of agricultural machinery over it, will it affect the soil texture over hundreds of years?
Soil texture will not change easily but if we continuously add organic manures, tank silt, green manures, and paddy root left over on the field, sugarcane trash left in the field, in the long run, changes the surface soil structure, texture, porosity, consistency but may not be subsoil texture.
@ Layth, to change soil texture is very difficult and it involves considerable mechanical and financial input. If your soil is mucky clay, you can improve its texture and structure by adding sand and compost. Sand will quickly improve the texture by separating some of the smaller mineral particles and allowing more openings for air and water circulation.

Compaction of soil is quite the hazard for crop production.
Excessive tillage can lead to soil hardening as the compacted clay can become impervious in aeration where moldboard plow sits creating plow pan condition.
Tillage in wet conditions can induce disturbance in the physical condition of soil.
Avoiding improper tillage is very important.
Soil structure can be favored by optimizing the Calcium and pH level and increas organic matter and sand in the soil which is clayey.
Permanent raised beds are an effective remedy for the way compaction inhibits root grown as zones of compaction are defined in the traffic pattern.

Soil texture take long time to change. However, tillage has all along been contributing negatively to soil quality. Since tillage fractures the soil, it disrupts soil structure, accelerating surface runoff and soil erosion. Tillage also reduces crop residue, which help cushion the force of pounding raindrops.
First, excessive soil tillage is associated with soil degradation processes such as compaction, a decrease in soil stability and structure, and increased soil erosion.
Second, Tillage modifies the soil physical properties. Usually, the bulk density of tilled soils decreases while the tillage implement compacts the soil underneath, creating, after repeated tillage operations, a plough layer that restricts water flow and root penetration and
Finally, It has been well documented that increased tillage intensities can reduce soil organic matter in the topsoil due to increased microbial activity and carbon (C ) oxidation. The potential loss of soil organic matter due to tillage operations is much higher for high organic matter soils than low organic matter soils.
La textura del suelo jamás se cambia si no es por eventos dramáticos como aluviones o grandes huaycos que suceden en algunas regiones del mundo, acá en Ica hay zonas donde se hace agricultura con un solo riego , en el periodo de verano donde se riegan los suelos una sola vez al año y se tienen melgas donde se almacenan entre 8 a 10,000 m3 /ha de agua de avenida con una alta carga de solidos en suspensión
como limo arcilla y materia orgánica, y año tras años se van aculando grandes cantidades de materiales finos, que a la larga pueden modificar la textura de los suelos.
Excess tillage can leave the soil prone to wind and water erosion with loss of lighter particles and consequent effect on texture.
Dear Layth Saleem Salman, By looking at the triangle of soil texture, we can see that the change of soil texture depends on time, place and climate. If the arable land is in slope condition, improper management of soil resources can shorten the time of soil texture change. One way to shorten the time of soil texture change is erosion.
This is an interesting question. Most of the answers provided so far make it clear that they did not really read the question.
I assume you are considering the fracturing of individual soil particles into smaller fundamental units, rather than the breakdown of soil aggregates.
I think this is very hard to answer, especially because no research project ever lasts the hundreds of years you refer to.
In my *opinion* (since there are no data) tillage is unlikely to change texture even when performed repeatedly. Because soil particles are aggregated, the tillage implement would tend to break the temporary bonds among them. These bonds are the weakest link in the chain, and it seems more plausible that they would break first, consuming the energy of the implement, rather than the energy being directed into fracturing the atomic structure of the soil mineral particles.
Of course soil particles break down into smaller units over time, but this is more likely due to natural weathering forces such as wetting and drying cycles and chemical reactions and not to the direct mechanical trauma induced by tillage operations. I suppose, however, that tillage could accelerate weathering processes by exposing more soil surface area to the elements.
In the end, I think that nobody knows for sure.
It would be extremely difficult to measure due to the long time scales and the possible confounding factors of erosion and mixing with depth, which would tend to wash out any clear treatment effect.
Estimado colega. La estructura, la composición, la distribución y el cambio Espacio/temporal del suelo es permanente y hasta a voluntad del hombre, a través de de los conocimientos científicos indetenibles y sus aplicaciones mecanísmicasy funcionales. Gracias por su atención.
Un ejemplo de los cambios delTODO UNIVERSAL véase publicación " Evaluación espació temporal de la sedimentacion del Embalse Burro Negro". Véase aquí en Researtga.net Saludos cordiales
La labranza es solo un elemento presente en las características de ese suelo.
Soil texture cannot be easily changed. I takes century above century. But if you take soil another soil textural class and mix with other texture, there is a posibility of some change overtime.
Soil texture cannot be easily changed. Ut takes more than 100 years. But if you mix soil having different textural classes you might change soil texture, but it is costy, it takes time and so on!
Se trata de una respuesta cuyo contenido podría ofrecer un ingeniero agrónomo, desde las normas jurídicas no conozco en Argentina una que trate la cuestión expresamente sugiero: https://www.scielo.sa.cr/pdf/tem/v31n1/0379-3982-tem-31-01-167.pdf
Soil texture cannot be easily changed but if the soil has been tampered with by any agent it might be slightly changed.
Texture simply referers to the proportion of sand silt and clay in the soil. So by tillage proportion does not change however the structure of the soil i.e. soil structure changes with the tillage operation.
Texture of soil is changes over long period by the processes like sedimentation or due to weathering etc. By tillage in my view soil texture has no effect.
Soil texture can not change with ordinary tillage operations. It is a static soil property. It is the proportion of sand, silt and clay content in the soil. Since tillage will not change the content of the three soil particles, it will not change the soil texture even after a long time. However, it can be improved through the addition of organic matter or altered by incorporating other textural classes which can be cumbersome and expensive. Conclusively, soil texture will not change with tillage
All parameters being normal the properties of soil texture will not demonstrate change, however, the effects of severe erosion however do leave their mark. See: https://library.dpird.wa.gov.au/cgi/viewcontent.cgi?article=1001&context=rmtr regarding' Wind erosion in the Jerramungup area 1980-1981' . I worked in that area in the early 1980s. The effects of wind erosion are so severe that there are road signs to alert drivers because of disappearing roads due to blown topsoil. When considerable amounts of soil texture components are blown away, the texture composition will logically change.
Caso muy similar ocurre en VENEZUELA, en la península de Paraguaná en el Estado Falcón: MÉDANOS DE CORO. Erosión Eólica muy intensa; allí también se bloquea de Arena la Autopista hacia la ciudad de Punto Fijo. Saludos cordiales.
Of course, tillage practices can affect soil texture over time. General definition of soil texture is the fineness and coarseness of the soil; therefore indiscriminate cultivations can pulverize the soil and ultimately reduce its texture to finness
Yes, soil texture can change over time due to tillage. Soil tillage can cause physical changes to the soil structure, such as increased fragmentation, which can lead to a decrease in soil texture over time. Tillage can also cause changes to the organic matter content and chemical composition of the soil, which can affect the soil texture. These changes can be seen over hundreds of years, although the extent of the change will depend on the type of tillage and the soil type.
Interesting question yes, soil texture can change over time due to tillage. Soil tillage can cause physical changes to the soil structure, such as increased fragmentation, which can lead to a decrease in soil texture over time. However, tillage has all along been contributing negatively to soil quality. Since tillage fractures the soil, it disrupts soil structure, accelerating surface runoff and soil erosion. Tillage also reduces crop residue, which help cushion the force of pounding raindrops. Tilling destroys soil's natural structure, breaking-up colloids and collapsing macro pores. The short-term result is a warmer, aerated and competition-free environment suited to seed germination and soil tillage generally decreases soil bulk density and increases soil porosity by loosening the soil. Therefore, intensive soil tillage can increase the likelihood of soil erosion, nutrient runoff into nearby waterways, and the release of greenhouse gases into the atmosphere.
El proceso d Erosión es PERMANENTE aún bajo el lecho del océano. Siempre será "áreas de Erosión, de Acumulación, áreas de equilibrio; además de áreas en Transición.
Yes, Texture often changes with depth down the soil profile. It is important to describe texture changes that occur within the soil profile. Many of our soils have loamy surface soils and heavy clay subsoil. Soil texture can change over time due to tillage. Soil tillage can cause physical changes to the soil structure, such as increased fragmentation, which can lead to a decrease in soil texture over time. However, tillage has all along been contributing negatively to soil quality. Since tillage fractures the soil, it disrupts soil structure, accelerating surface runoff and soil erosion. Tillage also reduces crop residue, which help cushion the force of pounding raindrops. Bulk and particle densities were decreased due to tillage practices, having the highest reduction of these properties and the highest increase of porosity and field capacity in zero tillage.
