“…It was concluded that CCs alleviated the effects of a tillage pan. A study conducted by Ess, Vaughan, and Perumpral (1998) on a loamy soil showed that cereal rye CC significantly reduced soil bulk density and increased noncapillary porosities compared to NCC at the 2.5-to 7.5-cm soil depth, even after multiple machine passes. It was suggested that soil compaction may have been alleviated by the reinforcing effect of a network of continuous roots within the soil.…”

Improving soil physical properties is important to soil conservation. Cover cropping can improve soil physical properties and organic matter content which can reduce soil loss, and thereby improve land productivity and environmental quality. In this article, the benefits of cover crops (CCs) for improving soil physical and hydraulic properties are reviewed as well as some soil conservation benefits that might accrue. The review indicates that CCs reduce soil bulk density by approximately 4%, increase macropores by approximately 33%, and increase water infiltration by as much as 629%, as compared to soil with no CCs. These improvements have been reported to lead to as much as 96% reduction in soil loss. Some current knowledge gaps in understanding how CCs can improve soil physical properties have been identified, including identifying which biomass, aboveground or belowground biomass, plays a greater role in organic C accumulation. Future research should focus on the interconnectedness of soil pores generated by CCs and the influence of CCs on heat transport parameters to further improve soil physical properties and associated benefits.

“…Few experiments studied soil compaction mitigation on the surface residue layer. Ess et al studied the cover crop effects on mitigating soil compaction with field experiments by analysing roots and surface biomass effects on soil characteristics and behaviour [8]. In addition, field tests with stress state transducers showed residues effects on soil stress compared to bare soil [9], but the quantity, type and conditions of residues was not defined.…”

“…Soil bulk density changes decreased below 100 kPa stress and increased over 400 kPa stress [12]. Few previous studies showed a complete approach to evaluate the residues effects on soil compaction [8]. Indeed, other studies were focused on residues effects only, without analysing the soil conditions due to the lying residues or cover crop growth [11,12].…”

How Much Impact Has the Cover Crop Mulch in Mitigating Soil Compaction?—A Field Study in North Italy

et al. 2023

Soil compaction was largely studied in different scenarios with laboratory and field scale experiments, with various soil conditions and traffic intensities. However, a detailed analysis to better understand the protective role of plant residues or cover crop mulch is still required. A field test was conducted in Northeast Italy aiming to fill this gap. Rye was chosen as a winter cover crop, and growth on a controlled traffic random block experimental field. Four different cover crop mulch treatments were compared to study the effects of root systems: roller crimper, flail mower, bare soil control and harvested biomass control. Four different traffic intensities were used to evaluate the multiple passages with 0, 1, 3, 5 traffic events. During traffic events, the mean normal stress was measured. Penetration resistance was then evaluated after trafficking and soil samples were collected. The obtained results showed a 19.3% cone index increase in bare soil compared to flail mower treatment after the first traffic event, while low differences were found in harvested biomass bulk density during the first and third traffic events. Moreover, mean normal stress increased 16.5% on harvested biomass treatment compared to the flail mower. These findings highlight that the cover crop maintains a lower soil penetration resistance during compaction events, helping the subsequent field operations. Furthermore, roller crimper and flail mower cover crop termination impact soil bearing capacity differently due to different soil moisture content. However, the results showed a low contribution of cover crop mulch on mitigating soil compaction effects during the experiment.

“…La escala espacial es variable, debido a que el territorio y muy especialmente las zonas montañosas, precisamente donde estas prácticas se suelen realizar, se caracterizan por presentar una elevada variabilidad medioambiental. Este hecho tiene una gran influencia sobre la capacidad de carga, porque está suficientemente demostrado en otras áreas científicas que la susceptibilidad del medio ambiente a la degradación depende de determinados factores ambientales (Youngs, 1983;Blackburn, 1984;Ess et al, 1998;Blanco, 2000Blanco, , 2004. Es decir, el impacto que puede provocar la práctica de las actividades recreativas que utilizan el viario tradicional puede variar de un área a otra dependiendo de la variabilidad normal de los factores medioambientales.…”

El aumento del interés del uso recreativo en los espacios naturales protegidos ha condicionado la aparición de nuevos conflictos e impactos ambientales, lo cual plantea la necesidad de planificar convenientemente estas prácticas. Las exigencias de sostenibilidad de estos espacios condiciona que sus documentos de planificación deban ordenar y gestionar adecuadamente dichas actividades, sin embargo, gran parte de los planes de ordenación y gestión carecen actualmente de una regulación óptima de las mismas desde un punto de vista territorial.En este artículo se analiza la regulación territorial de las prácticas recreativas en los documentos de planificación ambiental de los Parques Naturales andaluces. Las lagunas existentes en la planificación actual animan a desarrollar técnicas y herramientas que ayuden al gestor de éstas áreas protegidas a ordenar las prácticas mencionadas, en este sentido, los estudios de capacidad de acogida adquieren una importancia relevante al permitir determinar la carga real y potencial que presentan los recursos que sirven como soporte a las prácticas recreativas.
