Agricultural Water Management | Year: 2012
Irrigation scheduling of fruit trees according to the water balance showed significant differences between locations. In recent years, water status measurements such as leaf water potential have been suggested as irrigation tools in different fruit trees. The aim of this study was to adjust water potential threshold values previously studied and water application approaches that permit the estimation of irrigation requirements of olive trees based on midday stem water potential. The experiments were performed during three seasons (from 2005 to 2007) in two different locations (Badajoz and Ciudad Real) with different weather and cultural conditions. In both locations, the olive orchards were seven years old at the beginning of the experiment but had significantly different canopy development. In Ciudad Real the canopy shaded area at the beginning of the experiment was 15% and the first crop was harvested in 2003. On the other hand, the canopy shaded area of the olive orchard in the Badajoz experiment was 40% and the first crop was harvested in 2001. We therefore considered the Ciudad Real orchard as young and Badajoz as mature. Three different irrigation treatments were compared in both locations: Control treatment with traditional water balance as irrigation scheduling and two treatments in which midday stem water potential (SWP) provided the information about water management. In the midday stem water potential irrigation (WI) treatment the threshold value of SWP was -1.2. MPa before the beginning of the massive pit hardening period and -1.4. MPa after this date. Finally, in the deficit irrigation (DI) treatment the threshold value of SWP was -2.0. MPa throughout the season. In the WI and DI treatments irrigation was applied when SWP reached the threshold value. No significant differences were found between Control and WI in any of the seasons or locations when SWP, leaf conductance, shoot and fruit growth and yield (fruit and oil) were considered. In both locations, the same SWP value in WI treatment resulted in similar water application as the Control treatment. In DI treatment, shoot growth was significantly reduced in both locations in all the seasons. The SWP in DI trees was clearly affected in both locations, while leaf conductance was only reduced in the Badajoz experiment. In the Ciudad Real experiment no significant differences between DI and the other treatments were found in fruit growth, whereas differences were found in Badajoz. However, in Ciudad Real yield in DI treatment was significantly reduced, but not in Badajoz. WI treatment was successful for non-water-stress conditions. On the other hand, DI treatment was a mild water stress treatment which reduced yield only in low covered orchards, but not in the orchards with almost maximum canopy shaded area. © 2012 Elsevier B.V.

MoveCare develops and field tests an innovative multi-actor platform that supports the independent living of the elder at home by monitoring, assist and promoting activities to counteract decline and social exclusion. It comprises 3 hierarchical layers: 1) A service layer provides monitoring and intervention. It endows objects of everyday use with advanced processing capabilities and integrates them in a distributed pervasive monitoring system to derive degradation indexes linked to decline. 2) A context-aware Virtual Caregiver, embodied into a service robot, is the core layer. It uses artificial intelligence and machine learning to propose to the elder a personalized mix of physical/cognitive/social activities as exergames. It evaluates the elder status, detects risky conditions, sends alerts and assists in critical tasks, in therapy and diet adherence. 3) The users community strongly promotes socialization acting as a bridge towards the elders ecosystem: other elders, clinicians, caregivers and family. Gamification glues together monitoring, lifestyle, activities and assistance inside a motivating and rewarding experience. Off-the-shelf components are assembled in a robust and reliable way to get a low-cost multi-actor IP-domotic platform that can be massively deployed at elders home. The use of software/hardware standards assures interoperability and makes MoveCare adaptable to utmost novel components. Full configurability, personalization, adaptation to elder needs applies to all components to maximize elder compliance, even when computer illiterate. On-field testing starting early in the project assures an implementation iterative approach involving all actors. MoveCare identifies functional and technical metrics to characterize and evaluate the system by means of improvement in its abilities as described by the Multi-Annual Roadmap. The metrics lead to the definition of an evaluation framework transferrable to other fields

To understand the relations between water use and yield in response to crop load, two experiments were conducted in olive (cv. Morisca), during six consecutive years (2002-2007) in an experimental orchard located in Badajoz, Southwest Spain. Experiment 1, assessed the responses during the early years of the orchard (2002-2004) using four irrigation treatments that applied fractions of the estimated crop evapotranspiration (ETc) (125%, 100%, 75% and 0%) and three crop load levels (100%, 50% and 0% of fruit removal, termed Off, Medium and On treatments). Experiment 2 assessed the response of more mature trees (2005-2007) to three irrigation treatments (115%, 100%, and 60% of ETc) and the natural crop load which were Off, On, and Medium in 2005, 2006 and 2007, respectively. Yield was reduced by water deficits and so did the estimated tree transpiration which was linearly related to yield (y=1.2302x-21.15, R2=0.8864), showing the high sensitivity of cultivar Morisca to water deficits. The relations between fruit number and fruit weight showed that high crop loads had lower fruit weights and oil yield, a decrease that was more pronounced as water deficits increased. The yield response to water supply in the control and excess treatments, and the observations on the water relations of these two treatments suggest that the calculations made using the FAO method (Doorenbos and Pruit, 1974) with the crop coefficient proposed by Pastor et al. (1998) and the reduction coefficient (Fereres et al., 1982) to apply 100% of ETc in the control treatment, underestimated the ETc of the orchard. The results indicate that, although the absence of fruits lead to reduced water use as compared to situations of medium and high crop loads, canopy size was much more determinant of orchard water requirements than crop load. © 2011 Elsevier B.V.

Delineation of management zones (MZ), i.e. areas within the field which represent subfield regions of similar production potential, is the first stage to implement site-specific management. During the last years different algorithms have been proposed to define MZ, with different results. In this work, the use of an objective method, the formulation of the Rasch model, which synthesizes data with different units into a uniform analytical framework, is considered to get representative measures of soil fertility potential which could be used to delimit MZ. To illustrate the method, a case study was conducted in a experimental field using five soil properties: clay, sand and silt content, and deep (ECd) and shallow (ECs) soil apparent electrical conductivity (approximately 0-90 and 0-30. cm depths, respectively). Two main results were obtained after applying this method: (1) a classification of all locations according to the soil fertility potential, which was the value of the Rasch measure and (2) the influence on the soil fertility of each individual soil property, being ECs the most influential and silt content the less influential property.Later, from the measures of soil fertility potential at sampled points, estimates were carried out using the ordinary kriging technique. Consequently, kriged estimates were utilized to map soil fertility potential and MZ were delimited using an equal-size classification method, which practically coincided with the MZ determined by a unsupervised classification. It is also shown the possibility of using probability maps to delimit MZ or provide information for hazard assessment of soil fertility in a field. © 2010 Elsevier B.V.

Sustainability of biofuels is increasingly taken into account; therefore, sustainable production technologies are needed. There has been a long history of converting Jerusalem artichoke into ethanol. Jerusalem artichoke (Helianthus tuberosus L.) is a low-requirement crop, it has a high carbohydrates yield and, nowadays, it does not interfere with food chain. It is, then, a promising energy crop for sustainable bioethanol production. However, the main storage carbohydrate of Jerusalem artichoke, inulin, can not be directly fermented by classic fermentation yeasts, so, either a hydrolysis followed by fermentation with classical yeast or the use of yeasts with inulinase activity are required to obtain bioethanol. Therefore, it is needed to know not only total sugar content, but also their composition, for the bioethanol production optimization from Jerusalem artichoke tubers. Several methods have been used in literature for carbohydrates analysis present in Jerusalem artichoke tubers. However, for further development of carbohydrate analysis, faster and more reliable identification and peak confirmation, mass spectrometry (MS) detection is required. In this paper, liquid chromatography with electrospray ionization mass spectrometry (LC-ESI-MS) was used as an alternative technique to analyse sugars content and composition in tubers from Jerusalem artichoke. Two simple, rapid, sensitive and specific LC-ESI-MS methods were developed under the positive ionization mode. Glucose, fructose, sucrose, kestose and inulin were determined. Furthermore, inulin profile can be characterized. Analytical reversed phase LC columns were used using only water as eluent. These methods can be useful to optimize the whole bioethanol production chain from Jerusalem artichoke. © 2011 Elsevier Ltd.

The process followed by Spain to decide whether it should subscribe the International Convention for the Protection of Birds Useful to Agriculture, signed in 1902 is described. The fundamental role played by Mariano de la Paz Graells, one of the foremost Spanish naturalists of the 19th century, in the technical review and acceptance of the draft agreement, drawn up in 1895, is highlighted. Furthermore, a critical analysis of Graells's position in relation to this so-called first international convention for the conservation of certain wildlife species, has been carried out.

The main goal of this study was to assess the influence of the microencapsulation on the oil chemical composition and its oxidative stability. Factors such as microcapsule wall constituents and the addition of the antioxidant butylhydroxytoluene (BHT) were investigated in order to establish the most appropriate conditions to ensure no alteration of the extra-virgin olive oil chemical characteristics. The microencapsulation effectiveness was determined in base of process yield and the microencapsulation efficiency. Highest encapsulation yields were achieved when maltodextrin, carboxymethylcellulose (99.79 ± 0.51%) and lecithin were used as encapsulation agents and the ratio of oil-wall material was 1:1.5. Stability studies were achieved by placing encapsulated oil and un-encapsulated oil in heated chambers at 30°C during 4. months. Oxidative stability and oil quality studies were periodically assessed. It was concluded that the presence of protein constituents in the microcapsule wall material extended the shelf-life of the microencapsulated olive oil (protein-based model microencapsulated oil was unalterable for 9 to 11. months). For this later model, the addition of antioxidant additives did not significantly increase the oil stability. © 2011 Elsevier Ltd.

Climate change is promoting alterations of a very diverse nature in the life cycle of an array of insect species, including changes in phenology and voltinism. In Spain, there is observational evidence that the moth Lobesia botrana Den. & Schiff. (Lep.: Tortricidae), a key vine pest that is usually trivoltine in Mediterranean latitudes, tends to advance spring emergence, displaying a partial fourth additional flight, a fact that is potentially attributable to global warming. To verify this hypothesis, local temperatures were correlated with L. botrana phenology in six vine-growing areas of southwestern Spain during the last two decades (1984-2006) by exploiting the database of flight curves obtained with sexual pheromone traps. The dates of second and third flight peaks of the moth were calculated for each area and year and then correlated with both time (years) and local temperatures. The results obtained demonstrated a noteworthy trend towards local warming (as a result of global warming) in the last two decades, with mean increases in annual and spring temperatures of 0.9 and 3.0°C, respectively. Therefore, L. botrana phenology has significantly advanced by more than 12 days. Moreover, the phenological advance contributed to increased moth voltinism in 2006 by promoting a complete fourth additional flight, a fact that has never been reported previously to our knowledge in the Iberian Peninsula. The potential impact of an earlier phenology and increased voltinism in L. botrana is discussed from an agro-ecological perspective. © 2009 The Authors.

To determine whether root-to-shoot signalling of soil moisture heterogeneity depended on root distribution, wild-type (WT) and abscisic acid (ABA)-deficient (Az34) barley (Hordeum vulgare) plants were grown in split pots into which different numbers of seminal roots were inserted. After establishment, all plants received the same irrigation volumes, with one pot watered (w) and the other allowed to dry the soil (d), imposing three treatments (1d:3w, 2d:2w, 3d:1w) that differed in the number of seminal roots exposed to drying soil. Root distribution did not affect leaf water relations and had no sustained effect on plant evapotranspiration (ET). In both genotypes, leaf elongation was less and leaf ABA concentrations were higher in plants with more roots in drying soil, with leaf ABA concentrations and water potentials 30% and 0.2MPa higher, respectively, in WT plants. Whole-pot soil drying increased xylem ABA concentrations, but maximum values obtained when leaf growth had virtually ceased (100nm in Az34, 330nm in WT) had minimal effects (<40% leaf growth inhibition) when xylem supplied to detached shoots. Although ABA may not regulate leaf growth in vivo, genetic variation in foliar ABA concentration in the field may indicate different root distributions between upper (drier) and lower (wetter) soil layers. © 2011 Blackwell Publishing Ltd.
