dc.description.abstract | Today’s agriculture has the challenge of ensuring food supply for a growing population
while human activity has already deteriorated about 40% of the world’s soils, reducing productive
capacity and increasing reliance on mineral fertilizers. In this context, valorizing and recycling
mineral and agricultural waste for use as substrates or soil supplements enhance a sustainable
economy, as well as the development of activities focused on finishing the soil nutrients’ cycle.
Looking for an effective solution to the massive waste generation and to enhance the agronomic
qualities of soils, this study investigates the agronomic impact of contrasting inorganic and organic
materials such as green compost (GC), wood biochar (WB), rice husk ash (RA), and volcanic ash (VA)
as amendments to an alkaline Luvisol under controlled conditions. In this sense, barley seeds were
planted and grown in a greenhouse under controlled conditions for 60 days on a soil amended with the
aforementioned materials. The amendments demonstrated appropriate attributes for improving soil
agronomic properties, enhancing the soil’s nutritional content with no effect on barley germination.
The WB showed high aromaticity and abundance of refractory organic C. Both ash-rich amendments
showed high P and K contents, which are important elements for plant development. The GC has
high water retention capacity and an adequate C and N balance. Although the application of the
amendments had no effect on barley yields, the plants from the ash-amended pots showed an increase
of Photosystem II efficiency, indicative of a better physiological status. In terms of toxicological safety,
the abundance of trace elements in soils and plants was investigated. All soils met the maximum
allowable limits for these persistent pollutants. Nevertheless, longer-term tests on plants are required
to determine the risk of Pb accumulation, particularly in soils amended with GC and compost-ash
mixtures. The simultaneous combination of organic and inorganic amendments showed adequate
agronomic attributes. WB analysis revealed its great recalcitrance and carbon sequestration potential. | es |
