WP1. Development of a chain of waste management between farmer associations and urban agro-industries.

This activity is conducted by partner 4 and 5 with the objective to stimulate, establish and maintain a chain of waste management between potato and other crop farmers, producer associations in identified Peri-urban pilot sites and available either urban agro-industries involved in transformation of vegetal products or other sources of organic waste.

6 months (WP1)

Achievements:

In Bolivia as well as in Ecuador, visits were conducted to urban agro-industries (potato agro-industries), local authorities, NGO’s, farmers producer associations … to select pilot sites. Criteria for selection were presence of potato agro-industry and potato crop, organic waste residues (vegetable and animal), crop diversification, irrigation water, availability of communal infrastructure, predisposition for communal work, effective organization of stockholders, local authorities support, compost elaboration experience, distance to the local fairs (markets), roads, and communication.

In Bolivia, Peri- urban municipalities of Sacaba and Quillacollo, Cochabamba and several farmers producer associations in localities of Tiraque and Lope de Mendoza were visited, while in Ecuador, twelve sites (Pichincha, Cañar, Tungurahua, Chimborazo, Carchi) were visited.

Chain of waste management has been established with Cochabamba municipality  and between crop producers in the pilot sites.

Based on the visit and surveys, two pilot sites were selected in Bolivia (Cochabamba -  Provinces of Carrasco and Tiraque) and in Ecuador (Virgen de la Nube – Province of Cañar and Chaupiloma – Province of Pichicha).

 

12 Months (WP 1)

Agreements have been signed in Bolivia and Ecuador for the establishment of a chain of waste managements. These agreements have been signed with farmers (in Ecuador) and with a municipality producing waste in Bolivia. Therefore, urban organic waste residues and rural post-harvest residues will be available during the whole duration of the project favouring an efficient organic waste management for bio-compost preparation in pilot sites.

 This resulted in the successful completion of two deliverables

  • Cooperation rules on waste management between farmers associations and agro-industries (deliverable 1)

  • Availability of biological waste to farmer associations for microscale composting (deliverable 2)

18 months (WP1)

This activity is conducted by partner 4 and 5 with the objective to stimulate, establish and maintain a chain of waste management between potato and other crop farmers, producer associations in identified Peri-urban pilot sites and available either urban agro-industries involved in transformation of vegetal products or other sources of organic waste. .

Achievements :

 

a.      The chain of waste management has been started at the beginning of year 1 and consolidated since then both  in Bolivia and Ecuador.

b.      In Bolivia, agreements for compost production has been based on organic wastes from urban sources (Kara Kara, Environmental Unit for waste collection in Cochabamba city) and rural post-harvest residues (farmers in pilot sites). Biological waste is now made available to farmer associations for micro-scale composting.

In Ecuador, compost production in both sites (Virgen de la Nube and Chaupiloma) continued on base of vegetal and animal residues. Agreements with both communities exist since the starting date of the project.

WP2. Characterization of pilot sites in urban and peri-urban areas in the target region

This activity is conducted by partners 1a, 1b, 2, 4, 5 and 6 with the objectives to recognise the abiotic and biotic factors to be afforded by the experimental trials (knowledge about physical and chemical soil characteristics, diversity of PGPR, populations of diazatroph organisms associated to Glomalean spores in situ, characterisation of pathogenic communities) in the designated pilot sites.

6 months (WP2)

Achievements :

a.    In Bolivia as well as in Ecuador, soil samples of the pilot sites were sampled and processed for physico-chemical analysis and potato bio-essays.

b.    A long-term survey is under process involving agro-ecological social economic, politic and environmental aspects

c.     Studies on microorganisms functional groups are under investigation in full collaboration with partner 6.

d.    Soils samples were sent to partner 1a and partner 2 for the establishment of the culture collection of arbuscular mycorrhizal fungi (partner 1a) and PGPR (partner 2)     

12 months (WP2)

In parallel pilot sites were selected in Bolivia and Ecuador in urban and peri-urban areas to conduct all the experiments. In Bolivia two pilot sites were selected in the area of Cochabamba (Province Carrasco and Tiraque) and in Ecuador two pilot sites were selected in the Province of Canar (Virgen de la Nube) and in the Province of Pichincha (Chaupiloma). In Bolivia, the pilot sites have been fully characterized, considering their physico-chemical characteristics and their populations in micro-organisms (PGPR, AMF and other microbes), while in Ecuador, only physico-chemical characteristics and selection of Pseudomonas spp. and trichoderma spp. have been achieved. The other populations of micro-organisms will be assessed in year 2.

 

This resulted in the successful completion of two deliverables

  • Databank on environmental abiotic factors (deliverable 3)

  • Databank on biotic soil components (deliverable 4)

 

18 months (WP2)

This activity is conducted by partners 1a, 1b, 2, 4, 5 and 6 with the objectives to recognise the abiotic and biotic factors to be afforded by the experimental trials (knowledge about physical and chemical soil characteristics, diversity of PGPR, populations of diazatroph organisms associated to Glomalean spores in situ, characterisation of pathogenic communities) in the designated pilot sites.

 

Achievements :

 

a.       In Bolivia as well as in Ecuador, soil samples of the pilot sites were sampled at the start of the project. Part of these samples were send to partner 1 and 2 for AM fungi and PGPR isolation. The other soils samples were examined for abiotic and biotic components (partner 4,5 and 6).

c.     Sub-collections (in vivo) are maintained in Bolivia and Ecuador.

d.    Taxonomic identification of AMF sampled from the field is underway and being conducted by partner 6, while for PGPR (partner 2) characterisation is underway.

 

12 months (WP3)

The establishment, maintenance and characterization of a representative collection of AMF and PGPR collected from the pilot sites is underway. Some PGPR species are already characterized and maintained under standardized controlled conditions and are available to the partners of the consortium. Concerning AMF species, the process of cultivation is longer (several months of culture on trap plants), before isolation, characterization and distribution. From the first observations, species are present on the trap plants and are at present under isolation, purification and multiplication process. The first species will be identified during the second year of the project and available to the partners by the end of the second year.

Following these results, the two deliverables scheduled by the end of year 1 (see below) are partially completed for PGPR and underway for AMF. The establishment of the collections is started and will be completed during the whole duration of the project. Identically, the distribution of species will start begin year 2 for PGPR and presumably for AMF and will be maintained and reinforced during the duration of the project. 

  •  Establishment of a collection of AMF and PGPR (Deliverable 5)

  • Distribution of AMF and PGPR on request (Deliverable 6)

 

18 months (WP3)

WP4 : Development of microbial-coated potato technology and product

This activity is conducted by partners 3 and 6 with objectives to develop a low-cost, easy-to-use microbial inoculants for potato, based on the coating of tubers and/or emerging roots with indigenous AMF and PGPR selected from the micro-organisms collection (WP3). 

6 months (WP4)

Achievements : 

a.    A method to encapsulate AMF propagules (intraradical phase of the fungus) around potato seeds (tubers) has been developed.

b.    Natural encapsulation of tubers developed in inoculated soils with AMF is under investigation. This methodology aims at producing tuber seeds naturally entrapped with AMF strains. Substrate allowing such natural encapsulation on tuber is under investigation.

12 Months (WP)

The development of a microbial-coating potato technology and product is underway. At present three types of coating have been tested, all of which are economically-realistic and biologically sound. Results were positive with AMF.

The investigation of coating technology is started and will continue during the whole duration of the project. Therefore the deliverable scheduled under this activity (to be started month 0 and to be delivered month 36) is timely.

  • Development of microbial-coating potato technology (deliverable 7)

 

18 months (WP4)

This activity is conducted by partners 3 and 6 with objectives to develop a low-cost, easy-to-use microbial inoculants for potato, based on the coating of tubers and/or emerging roots with indigenous AMF and PGPR selected from the micro-organisms collection (WP3). 

Achievements :

 

a.       A method to encapsulate AM fungal propagules around potato seeds (tubers) with clay has been developed last year. This method showed some risks for contaminations. Therefore an identical process is underway using sterilized clays with microtubers and mycorrhizal propagules produced in vitro.

b.      Techniques are under process to produce AM fungi on callus, rooted callus and somatic embryos of potato. Hybrids formed by fusion of protoplasts between a variety resistant to nematodes (S. vernii) and non-resistant varieties (S. Phureja and S. tuberosum) were obtained. Calli were initiated from this hybrid and successfully  inoculated in vitro with AM fungi. The same process will be started on whole plant hybrids in vitro following the technique developed by partner 1. The hybrid will be made available to the partners of the project.

WP5: Development of micro-scale composting systems, based on management of organic waste from agro-industries, in collaboration with farmer associations

 

This activity is conducted by partners 4 and 5 with the objectives to identify at the local level and in close coordination with farmers associations appropriate facilities in pilot sites, for the development of composting systems, based on recycling of waste generated by urban agro-industries and /or other organic waste sources (see WP1) and local post harvest agro-waste generated in the fields of farmers associations.

 

Achievements :

 

a.       In Bolivia, micro-scale composting production based on organic waste from urban sources (Kara kara Unit) and/or rural post-harvest residues in combination with animal manures, have been carried out in three sites (Lope Mendoza in Carrasco Province, highlands in Tiraque province and Toralapa Experimental Station), and field trials have been established for their evaluation with farmers. Plant growth and tuber yield of different treatments will be participatory evaluated with farmers.

In Ecuador, 16 beds of compost have been located in Virgen de la Nube pilot site, and 10 in Chaupiloma. Vermicompost process has been initiated in 2 beds of Chaupiloma site.

WP6: Assessment of impact of microbial inoculants, compost and  microbial-coated potato product on potato based crop cultivation practices and on abiotic and biotic stresses in controlled and field conditions.

 

Will be started at the beginning of month 6. 

However, in order to speed up the research activities : 

a.    Potato varieties Solanum tuberosum cv. Desiree, S. phureja (CGN 18281) and S. phureja (CGN 18315) have been obtained to use as model plants. These have been introduced into in vitro tissue culture.

b.    An experiment is set up to investigate the mycorrhizal dependency of different potato varieties.

c.     Several assays are being conducted in in vitro conditions on the effect of Glomus intraradices on the growth and the development of potato plants.

12months (WP6) 

The study of the impact of microbial inoculants and bio-compost on potato growth and alleviation of abiotic and biotic stresses have no deliverables during year 1. However some activities were started.  In particular, the obtaining of an in vitro mycorrhizal whole potato plants will allow reproducible, standardized interactions studies with potato root pathogens and will allow investigation of the mechanisms involved.

18 months (WP6)

  •  

  • An in vitro mycorrhizal whole plant culture model system has been developed with different potato varieties. This system is the first whole plant in vitro system on which AM fungi grow, develop and produce thousands of spores. The model will be used to investigate abiotic and biotic stresses.
  • To validate this system, two experiments were set up aimed (1) to determine the infectivity of the AM fungi and relationship between intra and extraradical mycelium development and (2) to determine the effectiveness of the system by testing the transport capacity of radiolabelled phosphorus by the extraradical mycelium. Once both infectivity and effectiveness of AM fungi in such system are validated the system will be used to investigate various stresses under strict controlled conditions.   
  • An experiment was set up to investigate the mycorrhizal dependency of seven potato varieties, both in vivo and in vitro. Growth parameters, mineral content of shoots and tubers, and potato production are under investigation. The objective is triple (1) determine the effect of AM fungi on growth parameters, (2) sort out the plant characteristics in vivo (essentially parameters of root system such as weight, density and length of root hairs) which may be responsible of the observed results (some parameters may be used as predictive tools of potato variety dependency) and (3) to investigate if some parameters of potato grown in vitro may identically be used to predict dependency in vivo (this would represent a fast bio-assay of variety dependency determined from potato collections maintained in vitro).
  • First tests were conducted in vitro on the effects of  Bacillus and Pseudomonas spp. on growth and protection of potato against Rhizoctonia solani.
  • Trichoderma and Pseudomonas isolates from Ecuador are in the process of testing against potato root pathogens in Ecuador

WP7 : the diffusion within farmer field schools of trainings on bio-composting and micro-organisms management and the diffusion of the technology, cultural practices and product developed to farmers associations and NGO’s

The objectives of this WP are to provide guidelines and documents on the techniques and product developed to the end-users, (2) to provide and identify training capacities within agricultural colleges in order to develop a self-sufficient expertise, (3) to disseminate experiences and information generated by the project widely throughout the region and (4) to encourage local authorities (municipal entities, industries associations,…) to implement the actions taken during the project on a long-term basis. In this WP, farmers groups will be intimately associated to develop at the regional level micro-scale composting systems and microbial-coating potato technology. 

6 months

No task nor deliverable are scheduled during year 1. However, some activities were conducted by partner 2 … 

A website has been set up by partner 2 through the National University of Ireland, Cork’s website (www.ucc.ie/research/comminandes).  The site contains the official name and project number as well as objectives of COMMINANDES, the list of participants and their chief contact e-mail addresses. The website also has a schedule of the meetings to be  held between the partners. Partners using a project password can download reports regarding these meetings.

12 months (WP 7)

The diffusion of the technology developed has been started at three levels: (1) the development of a web site maintained at the following address: www.ucc.ie/research/comminandes.  This site describe the activities of COMMINANDES and has also a restricted area for the consortium. To reach a broad audience, the pages have been translated into Spanish with the co-operation of all South American partners. The Spanish pages are available through a direct link from the homepage or accessed directly at URL: http://www.ucc.ie/research/comminandes/indexSpanish.htm. (2) the development of numerous contacts with various stakeholders (farmers associations, responsible of programmes on urban management in Latin America), and (3) diffusion through media (local radio, local newspapers, documents on composting process diffused to the end-users).

18 months (WP7)

The diffusion within farmer field schools of trainings on bio-composting and micro-organisms management and the diffusion of the technology, cultural practices and product developed to farmers associations and NGO’s

Although to be started in month 40, partners attach large importance to communicate information on the project.

The website set up by partner 2 in year 1 (www.ucc.ie/research/comminandes) has been improved in different ways. (1) new information regarding the project has been added, (2) translation to Spanish will continue in close collaboration with partner 4, (3) the website address of COMMINANDES will be added to the website of PROINPA to increase visibility in LA. (4) PROINPA will send to partner 2 all literature that PROINPA may use to disseminate COMMINANDES related information. 

A discussion regarding online meeting is planned with a group list set up and hosted by partner 2. This will allow discussion to take place between partners and all comments will be delivered to partner’s individual mail address.
