Soil morphological properties described in the field, such as texture, consistence or structure, provide a valuable tool for evaluation of soil productivity potential. In this study, we developed regression model between variables banana plantations and crop Productivity Index (PI) previously same areas Venezuela. For this, implemented categorical regression, an optimal scaling procedure which are transformed into numerical scale, can thus be entered multiple analysis. The was from data six...

Gully erosion is one of the main processes soil degradation, representing 50%–90% total at basin scales. Thus, its precise characterization has received growing attention in recent years. Geomatics techniques, mainly photogrammetry and LiDAR, can support quantitative analysis gully development. This paper deals with application these techniques using aerial photographs airborne LiDAR data available from public database servers to identify quantify through a long period (1980–2016) an area...

Currently, there are some initiatives aimed at transforming agriculture from being a source to sink of greenhouse gases, mainly by encouraging combination management practices that drive nature-based climate processes (NbCS) resulting in an increase the stocks soil and biomass organic carbon. Olive grove cultivation represents key socio-economic environmental asset for Mediterranean rural regions. Being woody crop planted orchard fashion, potential carbon accumulation is very high. In this...

Summary A Quaternary fluvial chronosequence (Guadalquivir River, southern Spain), consisting of five soil profiles with estimated ages 300 years (Haplic Fluvisol), 7000 Calcisol), 70 000 (Cutanic Luvisol), (Lixic Calcisol) and 600 was studied. Increasing age associated increases in: reddening, development structure, clay content, dithionite‐extractable iron (Fe d ) aluminium (Al strengthening X‐ray diffraction (XRD) peaks for phyllosilicates oxides; there were also decreases in pH percentage...

In Southern Spain, olive trees have traditionally been cultivated in marginal areas with relatively shallow and bare soils under rainfed conditions, resulting heavy soil losses degradation. The implementation of temporary spontaneous cover crops the inter-rows groves, has proven to be a suitable diversification strategy reduce erosion but it can also contribute climate change mitigation boosting internal nutrient recycling. However, information on contribution atmospheric CO 2 fixation...

Mineralogical ( XRD ), crystallochemical DXRD geochemical ICP ‐ms and ICP‐AES ) spectroscopic colour DRS properties of the clay fractions confirmed that five soils (a F luvisol, two C alcisols L uvisols) on fluvial terraces in southern S pain form a genuine chronosequence extends back to 600 ka. Analyses showed goethite was more abundant than haematite. Both iron (hydr)oxide contents A l substitution (mole %) increased with soil age. The e (hydr)oxides came from transformation illites...

Management practices in the inter-row area of olive orchards are undergoing significant transformations. Current regulations and recommendations increasingly advocating implementation temporary spontaneous cover crops (TSCV) mainly to reduce erosion. Existing research has predominantly focused on evaluating effectiveness TSCV mitigating soil erosion orchards, with limited attention given carbon (C) cycling, despite potential for contributing removal atmospheric CO2 reduction eroded carbon....

Summary The effect of colloidal forces involved in the adsorption commercial humic acids ( HA s) and particle cohesion was studied soil an organic olive grove with extended D erjaguin, L andau, V erwey O verbeek (extended‐ DLVO ) theory. Total interaction energy determined from zeta potential ζ surface free energy, measured under different experimental conditions [natural hydrogen peroxide H 2 matter‐free mineral surfaces]. clayey, dominated by illite vermiculite. It showed electron‐donor...

In Southern Spain, olive (Olea europaea L.) growing is an important part of the economy, especially in provinces Jaén, Córdoba and Granada. This work proposes first stages Information Decision-Support System (IDSS) for providing different types users (farmers, agricultural engineers, public services, etc.) with information on environment, also assisting decision-making. The main purposes project reported this paper are to process uncertain or imprecise data, such as those concerning...

Under the Zero pollution action, there is a strong emphasis on promoting management practices that enhance nitrogen (N) cycling to decrease reliance inorganic N fertilizers and mitigate potential environmental impacts. Olive (Olea europaea L.) groves constitute dominant landscape of many areas Southern Mediterranean as Andalusia (Spain). Different farming models coexist in olive sector, but they had not been studied context cycle. By integrating field model data, we analyzed flows, balance,...

Summary A soil chronosequence from the R iver G uadalquivir ( S pain) was studied at a nanometre scale (10 −9 m), this being poorly investigated aspect of genesis. The fine mineral fractions (< 50 µm) were by X‐ray diffraction XRD ) and analytical electron microscopy TEM‐AEM ). At nano‐scale, dominant materials in dioctahedral 2:1 phyllosilicates, such as potassium mica (mainly muscovites illites), mixed‐layer smectite/illite smectite (beidellite). Sodium brammallite described for first...

Summary We studied the soils of Patio de la Acequia garden Generalife, a palatial villa forming part La Alhambra, World Heritage Site in Granada, Spain. This garden, which is estimated to be around 700 years old, oldest historical Western World. The are man‐made cumulimollihumic‐calcaric (hypereutric, anthric) Regosols. Noteworthy amongst main pedogenic processes, relation human activities cultivation, irrigation and tillage, horizonation, melanization (the contents organic carbon varied...

We studied the soil quality and response of olive trees (Olea europaea L.) to organic agriculture. Three factors were considered: management (organic conventional), parent material (calcareous colluvium marl), slope (upper, middle, lower). An increase in was observed plots colluvial soils. Moreover, we noticed an assimilation rate CO2 lower water deficit leaves under management, which are great importance semi-arid environments. These results indicate a relationship between physiological...
