We are about to start a new experiment on rhizoremediation of contaminated soil. Brassica juncea plants will be grown, under controlled Phytotron conditions, in soil simultaneously contaminated with metals and organic compounds. Different amendments (chicken manure, horse manure, etc.) will be used to both facilitate plant growth and stimulate the rate of contaminant degradation by rhizosphere microbial communities (i.e., bioremediation through biostimulation). In addition, bacterial strains isolated from the contaminated soil will be initially selected according to their (i) contaminant degradation potential and (ii) plant growth-promoting traits. A consortium of these strains will then be used for bioaugmentation purposes. Finally, apart from the reduction in the concentrations of the target contaminants, we will study the recovery of soil health, using a variety of physicochemical and microbial indicators of soil functioning, as a result of the application of the abovementioned rhizoremediation strategies.
Several groups of Neiker are working on the research project URAGAN, which aims a rational use of antibiotics in livestock. In the case of the Soil Microbial Ecology Group, we are concerned about the potential dissemination of antibiotic resistance genes and mobile genetic elements as a result of the application of animal manure in agricultural soil. In the short term, we plan to establish a pot experiment where we will apply several manures and grow different crops. We will use high-throughput qPCR to simultaneously analyze a great variety of antibiotic resistance genes both in soil and plants. To this purpose, this week we have collected manure and slurry in two dairy farms under organic and intensive management.
The Ministry of Agriculture and Fisheries, Food and Environment (MAPAMA) through the Biodiversity Foundation has granted aid for the NATURADAPT project, where we will continue working on the development of a methodology to assess the effectiveness of Nature Based Solutions for urban adaptation to climate change at different scales. The project will be carried out in collaboration with Tecnalia Research and Innovation, that will model variables related to reduction of temperature and uptake of runoff. Meantime, Neiker will be in charge of measuring carbon capture, as well as plant and soil biodiversity.

We have prepared a proposal on the combination of nanoremediation with zero-valent iron nanoparticles and bioremediation (biostimulation and bioaugmentation) of soils simultaneously contaminated with trace elements and organic compounds, in collaboration with IRAGAZ Company, Gaiker Technological Centre and the University of the Basque Country.
This week we have started sampling several agricultural soils from Navarra, as part of a new study carried out in collaboration with Sandra Blázquez from EDAR Arazuri (Navarra). In this case, we will study the potential impact of the application of sewage sludge on the presence of antibiotic resistance genes and mobile genetic elements in agricultural soil. To this purpose, we will use high-throughput qPCR to simultaneously analyse a great variety of antibiotic resistance genes. This is a new field for SMEG. Exciting!!
We are so happy to tell you that the project about developing agrosustainable schools in Uganda will be financed by Ner Group and Neiker one more year!!

In collaboration with Biolur, Eneek and Karabeleko, we are currently taking part in a project funded by the Basque Government (BERRIKER Programme) on the physicochemical and microbial characterization of urban composts from Gipuzkoa (Basque Country) for their potential use in ecological agriculture. During this project, the agroecological consequences of the utilization of urban composts will be assessed. Finally, different criteria for their application and utilization will be established. Apart from a traditional physicochemical characterization of these urban composts (including the determination of inorganic and organic contaminants), we will determine a variety of parameters that provided information on the biomass, activity and biodiversity of the microbial communities present in the studied composts.
Our project proposal entitled “Nature-based solutions for the ecological regeneration and restoration of urban and periurban areas in Donostia/San Sebastián” (acronym: NATUR-BIDEAK, 2016-2017) has been approved by IHOBE-Ecoinnovation Projects (Basque Government). The project has the following partners: TECNALIA RESEARCH AND INNOVATION and NEIKER-Instituto Vasco de I+D Agrario. This project will help us become familiar with the application of nature-based solutions for the ecological regeneration and restoration of urban and periurban areas. During this project, we will pay special attention to the assessment of biodiversity (belowground: microbial, mesofauna, macrofauna; aboveground: plants and birds) in the restored urban and periurban areas of Donostia/San Sebastián.
Our project proposal entitled “Design of a methodology to assess the sustainability of remediation plans for contaminated soil” (acronym: REMEDISOST, 2016-2017) has been approved by IHOBE-Ecoinnovation Projects (Basque Government). The main objective of the project is to develop a robust, reliable and rigorous methodology to properly analyse and assess the sustainability of plans for the remediation of contaminated soils aimed at recovering the functionality of degraded sites according to the intended land use. The project has the following partners: GAIKER-IK4 (coordinator), NEIKER-Instituto Vasco de I+D Agrario, BC3 – Basque Centre for Climate Change, and AFESA MEDIO AMBIENTE, S.A. Apart from sustainable remediation options, this project will help us become familiar with the methodology of Life Cycle Assessment that will be applied during the assessment of the different remediation plans.
Our Interreg Sudoe proposal entitled “Demonstration of the improving in soil biodiversity, functionality and ecosystem services of contaminated and degraded soils under phytomanagement within the Interreg Sudoe region” (acronym: PHYTOSUDOE, 2016-2018) has been approved. Phytomanaging polluted soils can gradually increase microbial diversity, carbon sequestration, and soil quality and functionality. However, the lack of field evidence demonstrating the provision of these vital ecosystem services has resulted in phytomanagement options being under-utilised as practical remediation strategies in the European contaminated land sector. PhytoSUDOE will demonstrate the environmental, economic and social benefits generated during and following phytomanagement and to encourage a wider use of these techniques by land use regulators and owners as an effective risk management strategy within the Sudoe territory and other European regions. This will be achieved by establishing a transnational network of contaminated sites (located in protected and non-protected areas but all of important ecological interest and potential to provide ecosystem services) under phytomanagement across the Sudoe region. The project has the following partners: CSIC-Instituto de Investigaciones Agrobiológicas (coordinator), Universidade de Santiago de Compostela, NEIKER-Instituto Vasco de I+D Agrario, Institut National de la Recherche Agronomique, Universidade de Coimbra, Centro de Estudios Ambientales de Vitoria-Gasteiz, Universidade Católica Portuguesa, Universidad del País Vasco, Universidade de Aveiro, and Laboratorio Nacional de Energia e Geología-Portugal. This project presents a great opportunity for us to further establish links with other groups working on the remediation of polluted soils.
