“…Before the cover crops were incorporated into the soil, the aboveground dry biomass was 11 ± 1.2 Mg ha −1 (with 2.8 % N content) for treatment V and 8.33± 2.1 Mg ha −1 (with 1.3 % N content) for treatment T. Our results are in agreement with previous studies, which observed that cover crops increase soil N content and soil organic matter (SOM) content (Jackson et al, 2004;Sainju et al, 2000, Ramos et al, 2010. In the experimental site we hypothesized a SOM increase after moving catch crops into the soil.…”

Abstract. When soil nitrate levels are low, plants suffer nitrogen (N) deficiency but when the levels are excessive, soil nitrates can pollute surface and subsurface waters. Strategies to reduce the nitrate pollution are necessary to reach a sustainable use of resources such as soil, water and plant. Buffer strips and cover crops can contribute to the management of soil nitrates, but little is known of their effectiveness in semiarid vineyards plantations. The research was carried out in the south coast of Sicily (Italy) to evaluate nitrate trends in a vineyard managed both conventionally and using two different cover crops (Triticum durum and Vicia sativa cover crop). A 10 m-wide buffer strip was seeded with Lolium perenne at the bottom of the vineyard. Soil nitrate was measured monthly and nitrate movement was monitored by application of a 15 N tracer to a narrow strip between the bottom of vineyard and the buffer and non-buffer strips. Lolium perenne biomass yield in the buffer strips and its isotopic nitrogen content were monitored. Vicia sativa cover crop management contributed with an excess of nitrogen, and the soil management determined the nitrogen content at the buffer areas. A 6 m buffer strip reduced the nitrate by 42 % with and by 46 % with a 9 m buffer strip. Thanks to catch crops, farmers can manage the N content and its distribution into the soil over the year, can reduced fertilizer wastage and reduce N pollution of surface and groundwater.

“…Cover cropping is currently the most effective practice for soil protection and maintaining the sustainability of the cropping system, as it can reduce soil erosion (Martínez et al, 2006;Pastor, 2008;Gómez et al, 2009) and increase soil organic matter and improve many other physical, chemical and biological properties of the soil compared with frequent tillage or non-covered treatments (Castro et al, 2008;Moreno et al, 2009;Ramos et al, 2010Ramos et al, , 2011. Cover crops, however, compete for resources with the trees, which can lead to a reduction in crop productivity (Hornig & Bünemann, 1993;Lipecki & Berbeç, 1997;Silvestri et al, 1999;Gucci et al, 2012).…”

Soil management in rainfed olive orchards may result in conflicting effects on olive production and soil fertility

The adoption of a sustainable soil management system is essential for the steep slopes and low fertility soils still supporting rainfed olive orchards in the Mediterranean basin. The effect of the soil management on olive yield, tree nutritional status and soil fertility was studied in a rainfed olive orchard located in NE Portugal that had been managed since its earliest days as a sheep-walk. In 2001, three different soil management systems were established: Sheep-walk, in which the vegetation was managed with a flock of sheep; Tillage, where the vegetation was controlled by conventional tillage; and Glyphosate, where a glyphosate-based herbicide was applied. The soil management systems had a pronounced effect on olive yield. The accumulated olive yields between 2002 and 2011 were 187.2, 142.9 and 89.5 kg tree-1, respectively in the Glyphosate, Tillage and Sheep-walk treatments. However, the effect of soil management on tree nutritional status was not so clear. On the other hand, the pools of organic carbon and N in the soil, and also the soil available N and phosphorus (P), were found to be less in the Glyphosate and Tillage treatments in comparison with the Sheep-walk. In these soils, N appeared as a much more limiting factor for crop growth than P. In rainfed orchards, the tolerance to herbaceous vegetation appears to be a determining factor in sustainability, which regulates annual crop yields and soil fertility. The higher the tolerance to herbaceous species, the lower the olive yields, but the better are the soil fertility parameters.

“…En primer lugar, se reduce la pérdida de materia orgánica adsorbida a los sedimentos al reducir la erosión hídrica (Durán et al 2012;Francia et al 2006;Gómez et al 2009,). El segundo motivo está relacionado con el incremento del contenido de materia orgánica al ser mayor la cantidad de residuos vegetales que se incorporan al suelo Nieto et al 2012;Ramos et al 2010). Y por último, se reduce la mineralización de la materia orgánica al ser menor la aireación del suelo por la reducción y/o supresión del laboreo (Beare et al 1994;Doran 1980;Melero et al 2009).…”

Efecto de técnicas de agricultura de conservación en la respiración del suelo en plantaciones de almendro en la región mediterránea (SE España) Resumen. El sistema de manejo de los suelos agrícolas puede modificar sustancialmente la dinámica del CO 2 del suelo. Se realizó un experimento en Lanjarón (SE España) para evaluar el efecto de tres sistemas de manejo de suelos en plantaciones de almendro: 1) mínimo laboreo y cubierta de vegetación espontánea (ML VE ), 2) mínimo laboreo y cubierta de tomillo (Thymbra capitata L.) (ML T ), y 3) mínimo laboreo sin cubiertas vegetales (ML). Las tasas de emisión del CO 2 del suelo presentaron el siguiente orden creciente ML VE >ML>ML T , determinándose una alta variabilidad a corto plazo. Así mismo, se registraron mayores emisiones de CO 2 durante la primavera, en contraste a las de otoño. Por otra parte, el contenido de agua en el suelo fue el factor ambiental con mayor influencia en las emisiones. En consecuencia, el empleo de técnicas de agricultura de conservación como el mínimo laboreo y cubiertas vegetales para el secuestro de C atmosférico son medidas sostenibles en los agroecosistemas mediterráneos de secano. Palabras clave: Cambio climático; CO 2 ; cubierta vegetal; mínimo laboreo; Prunus dulcis Mill.[en] Effect of different conservation agriculture techniques on soil respiration in almond orchards in the Mediterranean region (SE Spain) Abstract. The soil-management system in agricultural lands could be affected substantially on dynamics of CO 2 fluxes from soil. An experiment was carried out in Lanjarón (SE Spain) to evaluate the effect of three soil-management systems in almond plantations: 1) minimum tillage with spontaneous vegetation strips (MT SV ), 2) minimum tillage and thyme (Thymbra capitata L.) strips (MT T ), and 3) minimum tillage without plant strips (MT). The CO 2 emission rates from soil presented the following increasing trend MT SV >MT>MT T , showing highly variability in the short term. Also, higher CO 2 soil emissions were recorded during the spring, in contrast to autumn. Moreover, the soil-water content was the most influential environmental factor. Consequently, the use of conservation agricultural techniques such as minimum tillage and plant strips to sequester atmospheric carbon are sustainable measures for Mediterranean rainfed agro-ecosystems.
