In this work, sampling was carried out in the urban area of Madrid to analyze content total heavy metals (Zn, Pb, Cu, Cr, Ni, and Cd) street dust. Contamination evaluated using various indices, such as Factor (CF), Enrichment (EF), Geo-accumulation Index (Igeo), Potential Ecological Risk (RI), Pollution Load (PLI), Human Health Hazard (HI), Cancer (CR). indices were related traffic density color. Traffic factor that most influenced values pollution indexes, but no significant differences...

In the present work, a sampling grid of urban core city Murcia (South East Spain) was designed in order to analyze street dust, focusing on contents heavy metals Cd, Cr, Cu, Ni, Pb, and Zn their relationships with color sample, traffic pattern, location where they were sampled (sidewalks, ledges, roads). The characterization samples carried out by X-ray diffraction scanning electron microscopy, whereas extracted acid digestion determined inductively coupled plasma mass spectrometry....

Abstract BACKGROUND: The objective of this work was to study the influence irrigation and organic fertilisation on quality attributes tomato fruit (cv. Nautilus) grown for canning industry. assay carried out during two consecutive years (2006 2007) in agricultural soil. Nine treatments resulting from combination three types (sheep manure, a mixture sheep manure peat an inorganic fertiliser (control)) with levels drip (3.30, 5.00 6.70 mm day −1 ) under black polyethylene mulch were applied (...

The environment is affected by most anthropogenic activities; among them, agriculture one activity with more negative effects, especially when management inadequate, causing soil degradation or contamination. This paper presents the results of an agronomic field trial on a spinach (Spinacia oleracea L.) crop. objective which was to monitor and crop properties under two doses irrigation organic fertilization. showed that use excessive fertilization increased electrical conductivity (ECext)...

For some years now, part of society has been demanding the implementation circular economy models and so use organic matter as a source nutrients is once again taking center stage. In this scenario, aim work was to implement an integrated management model for farm study influence on celery crop amendments (animal vegetable) obtained farm, opposed inorganic fertilization. This evaluated yield nutritional, organoleptic, sanitary quality resulting crops. The size marketable parts plants were...

Agriculture practices developed since the middle of last century have led to degradation different resources and made it necessary promote agricultural models that are less aggressive towards nature. Sustainable growth requires a more efficient use land. An experimental model was designed with four treatments in Campo de Cartagena area (SE Spain): biosolarization manure (BSM), brassicas (BB), solarization (S), pilot test (PT). The general objective determine by means rapid response...

Urban dust samples were taken from the playgrounds of 27 schools located in urban area city Murcia (S.E. Spain). Their color and degree magnetism determined, as well their heavy metal content (Cd, Cu, Cr, Ni, Pb Zn) to evaluate contamination by environmental health indexes. The highest concentration contaminants is found dusts dark medium high magnetism. concentrations metals were, this order, Zn (453.74 mg kg-1)> Cu (77.44 Cr (67.93 (55.72 Ni (18.56 Cd (0.42 kg-1). analysis magnetic...

This study shows the influence of soil salinity and irrigation dose on biomass production its impact some edaphic indicators functions. For this purpose, an experiment was carried out in two representative soils from Murcia (SE Spain), one slightly saline (LS) other (S), where oat–vetch green manure intercalated between a spinach cycle coriander cycle; latter being subjected to three different doses (deficient, optimum surplus). Rapid response (ECext, cations anions solution, etc.) were...

The aim of this study was to evaluate the possible contamination urban dust in schoolyards 27 schools an area city Murcia (SE Spain). color and degree magnetism, as well heavy metal content (Cd, Cu, Cr, Ni, Pb, Zn), were determined establish absence or contamination, if present, using environmental health indices. It established that concentrations metals samples followed order Zn (454 mg kg

The response of a Petrocalcic Palexeroll dedicated to the cultivation vegetables (Apium graveolens L.) with rotation mixture cereals and legumes when organic amendments are added has been studied; specifically, three fertilization treatments were experimented with: two (LSM COA) one chemical fertilizers (I). LSM COA plots managed according regulations governing production, while in I, conventional agricultural production practices used. Over three-year period, monthly samples taken from...

Abstract The development of an organic matter (OM) based on mixed sheep manure and peat, when it was incorporated into soils as fertilizer, studied. experiment carried out in under almond tree culture, with drip irrigation non regimes. Two doses, 10 4.5 kg –1 , were assayed. Changes the humic acid fraction one year after incorporation showed oxidation enrichment condensed structures, observed by increase O*:H* ratio a decrease H*:C* ratio, also FTIR spectra. oxidative process more...

In the present work, a study has been carried out on contamination of heavy metals in urban dust deposited roads city Cartagena (Spain) order to know content such as Ni, Zn, Pb, Cd, Cr and Cu. Likewise, possible relationship between concentration color sample, level magnetism traffic density was studied. Contamination evaluated using several indices factor (CF), enrichment (EF), geo-accumulation index (Igeo), pollutant load (PLI) ecological risk (RI). A total 88 samples were taken area...

The evolution of soil chemical properties over 20 years was monitored to assess the effects change in management from a rainfed an irrigated model and use organic amendments crop rotation. Intensive agriculture has been activity that caused most degradation contamination this soil. Long-term monitoring profile made it possible its response application sustainable agricultural techniques intended offset these effects. Three profiles same were studied—P1 (1998), P2 (2003), P3 (2017)—to show...

In the present work, a study has been carried out on contamination of heavy metals in urban dust deposited roads city Cartagena (Spain), order to know content such as Ni, Zn, Pb, Cd, Cr and Cu. Likewise, possible relationship concentration with color sample, level magnetism traffic density was studied. Contamination evaluated using several indices factor (CF), enrichment (EF), geoacumulation index (Igeo), pollutant load (PLI) ecological risk (RI). A total 88 samples were taken area...

For this study two fertilisation assays were carried out in an experimental field. The first assay (F1) used a sheep manure amendment, following the stipulations of European regulations concerning organic agriculture practices, and second (F2) followed conventional agricultural practices area using inorganic fertilizers (313; 37 566 kgha-1 N, P K, respectively). Over three-year period, samples arable soil layer taken monthly order to analyse properties as indicators quality (organic carbon,...

The electrical conductivity (EC) and ionic composition of the soil solution a Haplic Calcisol in Campo de Cartagena (Murcia, Spain) were studied <em>in situ</em> for four years an experimental open-air vegetable plot, together with relationship between these parameters, quality irrigation water management plot. results show that there very significant fluctuations variables during study period depended on plot particular used. Therefore, adequate agro-ecosystems, it is necessary...
