Using treated wastewater as fertilizer: The first SOILdarity training course

The first SOILdarity training course is getting started!

Phosphorous (P), a non-renewable resource, has been applied extensively in farm fields and orchards to increase crop yield, yet consequently has increased the potential of waterway eutrophication. Hence, there is an urgent need to develop an innovative method of P capturing, recycling and reuse that will sustain agricultural productivity while concurrently reducing the level of P discharge from and to agricultural settings.

Against this background, SOILdarity has organized a multi-module course on the “Optimisation of the use of treated wastewater as a source for alternative fertilisers”.


The course is totally free of charge but
places are limited, so hurry up! Registration is open until 6 July 2021, 23:59 (Portugal Time).


The Content of the Course

The course is held by Prof. M. Iggy Litaor, who leads the MIGAL team, which is also made up of the Lab. Assistants Oren Reichman and Adi Zarka.

They will explain the principle behind MIGAL’s new patent on the subject and will address the following topics:

  1. Introduction to P cycling including eutrophication processes of water ways, expected global P scarcity and its influence on the green revolution;
  2. Physical and chemical characteristics of alum residue (Al-WTR);
  3. Mechanism of adsorption capacity of Al-WTR;
  4. Adsorption kinetic models;
  5. Adsorption equilibrium isotherm models;
  6. Adsorption dependency on pH;
  7. P adsorption is more favoured by small/fine particle size ranges than with bigger sized particles;
  8. Results of retention time; dependency on experimental conditions;
  9. Competitive Ions;
  10. Dosage of adsorbent.

When & Where

19-23 July 2021 (Theoretical Module via Zoom)
26-30 July (Presential Practical Module)

Both theoretical and practical classes will be held from 9:00 – 17:00 (Portugal time)

The practical module will take place at Faculdade de Ciências- Universidade de Lisboa

The course is open to researchers and students from FC.ID and the Faculty of Science of the University of Lisbon who have an adequate background and knowledge of the course subject.

Online Workshop on Women Empowerment, Gender Equality and RRI – Registration Open

The current COVID-19 pandemic has underlined the critical role that science and women’s empowerment play for driving progress forward across the 2030 Sustainable Development Agenda. Against this background, SOILdarity supports the need to better leverage the skills of women in science.

The research team holds a workshop on women empowerment, gender equality, responsible research & innovation on 27 April 2021 (in English) 9:30 – 16:30 (GMT+1).

In the online workshop “Women empowerment, gender equality, responsible research & innovation” taking on 27 April 2021, the team of the project “SOILdarity” would like to invite stakeholders from research, business, politics, civil society to discuss and review the key issues revolving women empowerment and gender equality in research, women in entrepreneurship, main obstacles to develop a successful professional career inside formal organizations, women in policy affairs, the institutional support to women empowerment in sciences and in science management.

The event aims to increase awareness about women opportunities/obstacles in the labour market and promote a debate about specific policies and programmes for women in research and innovation.


Knowledge knows no gender

But in EU-27 women are:

  • 41% of the scientists/engineers
  • 48 % of the PhD graduates
  • 33 % of the researchers
  • 24 % of the academic leaders

Water management, plant-soil interactions, alternative fertilizers – SOILdarity training programme

SOILdarity has been launching its first training programme!

The programme is made up of two specilised courses:

  1. The multi-module course on the “optimisation of the use of treated waste waters as a source for alternative fertilisers”, and
  2. The multi-module course on “soil ecology in dry ecosystems”.

The courses will be held in Lisbon and will be given from June 2021.

Course 1: Optimisation of the use of treated waste waters as a source for alternative fertilisers

Phosphorous, a non-renewable resource, has been applied extensively in fields to increase crop yield, yet consequently has increased the potential of waterway eutrophication. Hence, there is an urgent need to develop an innovative method of P capturing, recycling and reuse that will sustain agricultural productivity while concurrently reducing the level of P discharge from and to agricultural settings. We will demonstrate the applicability of the widely produced by-products of drinking water utilities and desalinization plants known as Aluminum-based Water Treatment Residual (Al-WTR) and Iron-based Water Treatment Residual (Fe/WTR) respectively. Al- and Fe- WTR are known as an excellent P adsorbent and could be used to recover P from agricultural wastewaters; subsequently, it could be applied to the fields as a P fertilizer. We will show that Al-WTR and Fe-WTR behave as sinks and will adsorb inorganic P (Pi), along with organic P (Po), dissolved organic matter (DOM) and other constituents from agro-organic wastes. We will demonstrate that the sorption of multiple constituents generates an Al/Organic Composite (Al/O-WTR) and Fe/ Organic Composite (Fe/O-WTR) that will desorb Pi and Po more effectively in the field compared to Al-WTR and Fe- WTR. The workshop objectives are: 1) to develop a thorough understanding of the sorption mechanisms of Pi and Po onto the Al/O-WTR and Fe/O-WTR; and 2) to critically evaluate the performance of the composite WTRs as a fertilizer using selected plants grown in screen-houses and in test-fields.

Course 2: Soil ecology in dry ecosystems

Although hidden from the eye, it is becoming more and more clear, that the ecology of soil processes can have far reaching effects on the aboveground ecology of natural and agricultural habitats. The role of soil microbes in affecting forest health and crop yields is currently unravelling. The course will be made up of classroom lectures in which the role of soil microbes (with an emphasis on mycorrhiza and rhizobium) on forest ecology will be discussed. Each day will include a morning lecture followed by a field trip related to the taught material. Some of the topics that will be covered include nutrient cycling, the role of soil microbes in forest regeneration after disturbance, soil ecology and its effect on plant health, competitive interactions within the soil, plant soil feedback and their effect on plant community dynamics, soil microbes and invasive plant species.
