Arbuscular mycorrhizal fungi (AMF) and their product glomalin (GRSP) play a decisive role in the soil aggregation, affecting carbon (C) dynamics agroecosystems.Tillage affects AMF activity GRSP content, influencing stability C forms as well.The aim of this study was to compare effect no tillage (NT) conventional (CT) on: i) arbuscular hyphal length content; ii) nature organic matter by means physical fractionation (free particulate [fPOM]; occluded [oPOM] mineral-associated [Mineral]), well...
Berberis empetrifolia L. and darwinii H. are native mountain plants of Chile Argentina, characterised by their benzylisoquinolic alkaloid content. This research aims to analyse benzylisoquinoline alkaloids antibacterial activity in root extracts A methanol extract was separated column chromatography through a polarity gradient were HPLC ESI-MS/MS. Antibacterial against Gram-positive Gram-negative assessed. The results showed the presence protoberberine aporphine total chloroform-methanol...
Soil compost application is a common soil management practice used by small farmers of Central-South Chile that produces positive effects on properties and also promotes presence activity arbuscular mycorrhizal fungi (AMF).This form symbiosis with plant roots improving nutrition, as well producing glomalin, glycoprotein has been associated aggregation stability.Therefore, the aim this study was to evaluate, in an Ultisol from Chile, effect different doses some characteristics at end third...
The use of biochar in agricultural soils appears to be promising because it is known improve soil properties and increase crop production.However, few studies have been conducted with on volcanic soils.Two field experiments were simultaneously evaluate the effect oat hull (OBC) various physical-chemical two soils, an 'Inceptisol' 'Ultisol', resulting effects yields barley (Hordeum vulgare) grown these soils.The OBC doses applied microplots equivalent 0, 5, 10 20 Mg ha -1 .The results showed...
Abstract. A critical aspect of predicting soil organic carbon (SOC) concentrations is the lack available information; where information on characteristics available, it usually focused regions high agricultural interest. To date, in Chile, a large proportion SOC data have been collected areas intensive or forestry use; however, vast beyond these forms land use few no available. Here we present new database for country, which result an unprecedented national effort under framework Global Soil...
Arbuscular mycorrhizal (AM) association plays a key role in the sustainability of terrestrial plant ecosystems, particular those presenting limitations for establishment and subsequent growth plants.In Chile, more than 50% arable soils are originated from volcanic ashes, showing general several constraints to crop production, such as low pH, high exchangeable aluminum content levels available P. Under these conditions, management AM fungal propagules using adequate cultural practices emerges...
ABSTRACT A study was conducted to evaluate the effects of aluminum (Al) in nutrient solutions on dry weight (DW) yield, Al and phosphorus (P) contents, organic acid exudation alfalfa (Medicago sativa L.). Four cultivars ('Robust', 'Sceptre', 'Aquarius', 'California-55') were grown solution at pH 4.5 6.0, with (50 100 μM) without Al. The results revealed that caused a significant reduction DW, especially treatment. Organic affected by treatments. Citrate succinate increased high treatment...
Biochar is a carbonized material obtained from the pyrolysis of biomass produced in limiting environment zero or very low oxygen. Its interest lies its versatility for different applications water treatment, soil pollution, mitigation greenhouse gases, etc. The synergy this product with other amendments such as compost has been studied soil, including environmental remediation, crop yield, aim research to identify relevant aspects scientific literature biochar, and through bibliometric...
In this study, the physiological performance and fruit quality responses of highbush blueberry (Vaccinium corymbosum) cultivar Legacy to high temperatures (HTs) were evaluated in a field experiment. Three-year-old V. corymbosum plants exposed two temperature treatments between load set harvest during 2022/2023 season: (i) ambient (AT) (ii) (HT) (5 °C ± 1 above temperature). A chamber covered with transparent polyethylene (100 µm thick) was used apply HT treatment. our diurnal maintained...
Arbuscular mycorrhizal fungi (AMF) have an important role on the ecosystem stability promoting water and nutrient acquisition by plants allowing their growth under stress conditions including drought salinity.This study aimed at describing colonization of native AMF associated to pioneer plant species growing mouth lake Budi, which receive seasonally marine water.For this, root samples rhizosphere substrate Polygonum maritimum, Carpobrotus chilensis, Ambrosia chamissonis, Ammophyla arenaria...
Abstract. One of the critical aspects in modelling soil organic carbon (SOC) predictions is lack access to information which usually concentrated regions high agricultural interest. In Chile, most and SOC data date highly 25 % territory that has intensive or forestry use. Vast areas beyond those forms land use have few no available. Here, we present a new database for country, result an unprecedented national effort under frame Global Soil Partnership help build largest on Chile named...
El objetivo de este estudio es determinar las potencialidades los pastos más utilizados en sistemas producción familiar la provincia Los Ríos, Ecuador, durante el verano. se realizó áreas investigación y Laboratorio Ruminología Metabolismo Nutricional Universidad Técnica Estatal Quevedo. Las especies utilizadas ganaderos fueron seleccionadas para realizar estudios comportamiento productivo (biomasa total, RMS hojas tallos) calidad (MS, PB, cenizas, MO, P, Ca, FDN, FDA, LAD, Cel, Hcel, CC,...
Agroforestry systems (AFSs) have gained recognition as a land use strategy to address food security and climate change. They involve intentionally cultivating trees alongside crops and/or animals. AFSs cover approximately 5% of the global forest area promote sustainable soil conservation, including organic carbon (C) sequestration (CSEQ). In some areas Chile, are used preserve ecological value native forests. This study evaluates effects two AFSs, namely, an agroforest for fodder production...
Organic waste generation in aquaculture worldwide requires circular economy approaches. The revalorization of wastes the Chilean salmon industry could be a potential soil amendment. We investigated thermo-drying process on sludge, evaluating it as an alternative to reusing horticulture. chemical characterization untreated sludge (wet sludges: WS) and dried sludges (DS) were evaluated with thermogravimetry, IR spectroscopy, fluorescence. Additionally, germination index DS was determined L....
