Number (per core) and diversity of Collembola (family level) and Acari (sub-order level), for the 0-to 10-cm soil depth in the potato phase of 2-and 3-yr rotations in the 10th yr of conventional and conservation tillage management Increases in SOC in the surface soil, in combination with surface tillage, has been shown to have benefits for soil water-holding ability for potato systems on the same soil type as the present study (Carter 2007). Mallory and Porter (2007) also found a positive relation between increased SOC levels due to improved management in short-term potato rotations and soil moisture content.…”

“…This ongoing improvement in soil structural stability, under conservation tillage, is a positive development in shortterm potato rotations. In the same soil type as the present study; an improved soil structure was associated with a concomitant improvement in soil porosity parameters and increased soil water-holding capacity (Carter 2007).

Conservation practices in potato (Solanum tuberosum L.) cropping systems can reduce excess tillage, provide crop residue cover, and maintain crop productivity; however, little is known about their long-term influence on soil biota and biological properties. Conservation tillage was evaluated in two potato rotations: a 2-yr barley-potato rotation and 3-yr clover-based (barley-red clover-potato) rotation initiated in 1994 on a fine sandy loam (Orthic Podzol) in Prince Edward Island, eastern Canada. Soil samples were obtained in 2003 from the 0- to 10-cm soil depth of the potato phase of both rotations to evaluate the influence of conservation, compared with conventional tillage, on changes in soil fertility, soil structural properties, soil C and N fractions, soil-borne pathogens, nematode communities, and micro-arthropod (Collembola and Acari) communities. The 3-yr conservation tillage practice improved soil structural stability, increased soil extractable P and K, increased soil organic C and total N and their particulate fractions, compared with the other treatments. Comparisons with earlier studies indicated that soil organic C had reached an equilibrium level at the 0- to 10-cm soil depth. Reduction of potato disease caused by Rhizoctonia solani was evident in the 3-yr rotation, compared with the 2-yr rotation, but was not influenced by tillage practice. Plant parasitic nematodes were not greatly influenced by rotation and tillage treatments; however, densities of the beneficial bacterial-feeding nematodes were increased under the 3-yr conservation tillage treatment. The abundance of micro-arthropods was increased by conservation tillage, while their diversity was mainly influenced by the rotation cycle rather than tillage practice. Overall, the 3-yr conservation tillage treatment provided a more beneficial soil biological condition than the other treatments, especially when compared with the 2-yr conventional tillage practice. Key words: Conservation systems, potato rotation, fine sandy loam, soil fertility, soil organic C and N fractions, soil structure, soil-borne pathogens, nematode, Collembola; Acari

“…En las propiedades físicas evaluadas no se detectaron modificaciones estadísticamente significativas entre los tratamientos y el control, con excepción de CBIO que presentó menor infiltración básica (Tabla 4). Si bien hay estudios que documentan cambios en las condiciones físicas en suelos tratados con compost, las diferencias con este trabajo son el número de aplicaciones (Carter, 2007) o bien los rasgos granulométricos del suelo tratado. observaron modificaciones en la densidad aparente en un suelo arenoso de baja estabilidad estructural tratado con compost.…”

“…El efecto de la adición de compost sobre las propiedades físicas del suelo no muestra resultados concluyentes: mientras algunos señalan modificaciones, otros no detectaron efectos cuantificables. Se ha reportado un incremento de 3,4 % en la capacidad de campo de un suelo tratado durante 12 años con compost (Carter, 2007). Otros estudios reportaron incremento en la porosidad total después de cinco años de aplicaciones de compost (Giusquiani, Pagliai, Gigliotti, Businelli y Benetti, 1995).…”

Se evaluó sobre el suelo el efecto de diferentes compost, obtenidos mediante igual metodología de compostaje, después de dos años de aplicados. Sobre un suelo Haplustol típico se aplicaron 40 Mg ha-1 de cada compost, conformando los siguientes tratamientos: CBIO con compost de biosólidos, CF con compost residuos de estiércol bovino, CG con compost de guano de gallina, CROU con compost de residuos sólidos urbanos. También se incluyó un tratamiento con fertilizante inorgánico (FI) y un suelo no tratado o control (C0). El pH del compost afectó ligeramente el pH del suelo, según las características del compost usado. CROU y CBIO incrementaron y disminuyeron el pH, respectivamente (R2=0,98). Se observó un cambio en la distribución de la materia orgánica del suelo CG, sin incremento en el carbono orgánico total (COT). En CG aumentó un 85 % el Cfraccion>53um y creció en 24 % el C extractable en álcali, respecto al control. Finalmente, se observó un enriquecimiento de CuM y ZnM en CROU. Los resultados muestran que una única adición de compost puede modificar las propiedades del suelo dado los múltiples materiales compostados. Se debe monitorear tempranamente las condiciones del suelo para identificar tendencias y evitar efectos ambientales negativos.

“…There have been many studies that have analysed the positive effect of biowastes on bulk density, water retention, plant-available water, aggregate size and structural stability (Carter, 2007;Hernández et al, 2015;Khaliq and Abassi, 2015;Aranda et al, 2016;Aranyos et al, 2016;Esmaeelnejad et al, 2016;Ferreira de Araújo et al, 2016;Forge et al, 2016;Moreno et al, 2016;Omondi et al, 2016;Sall et al, 2016;Yazdanpanah et al, 2016). These authors studied degraded soils (Arenosols, Fluvisols and Lixisols, in terms of WRB, 2014) under tropical or boreal climates, sandy textures and a lack of organic matter.…”

We investigated the short-term effects of spent coffee grounds on the physical properties of two Mediterranean agricultural soils (Calcisol and Luvisol). The in vitro assay was performed with two spent coffee grounds doses (60 and 240 Mg ha-1), two incubation times (30 and 60 days) and two modalities: with and without lettuce seedlings (Lactuca sativa var. longifolia). Spent coffee grounds addition increased water retention at-33 and-1500 kPa, and decreased bulk density and plant-available water content. With spent coffee grounds, the percentage of macroaggregates increased, the percentage of meso-and microaggregates decreased and the structural stability of all types of aggregates increased. The stereomicroscopy images showed that: the structural aggregates were rounded, the porosity increased by 316%, the structure was ordered into smaller aggregates, the incorporation of spent coffee grounds particles could occur in intraped cracks and spent coffee grounds particles could act as a binding agent. Scanning electron microscopy also showed that spent coffee grounds particles interacted with mineral particles and integrated into soil structure; moreover, fungal hyphae also developed on many spent coffee grounds particles. If spent coffee grounds effects are compared with those described in the literature for other organic amendments, the same trend was observed in most of the soil physical properties although with a different intensity, principally with regard to structural stability. K e y w o r d s: organic amendment, soil aggregate stability, soil water retention, soil aggregate size, SEM images
