Resumo: | Biochar has received great attention as a soil conditioner since it can potentially sequester carbon (C) in soil, enhance soil physical, chemical and biological properties and improve crop productivity. This study reports the results of a pot experiment with olive (Olea europaea L.), carried out in an acidic and clay loam textured soil, and cultivated during two growing seasons under eight fertilization treatments. They included mineral fertilization equivalent to a rate of 100 kg ha-1 of N, P2O5 and K2O (NPK), biochar applied at a rate of 10 (B10), and at 20 (B20) t biochar ha-1, biochar-NPK mixture (B10+NPK), biochar-waste mixtures with mushroom waste compost (B10+MWC), olive mill waste (B10 + OMW), and municipal solid waste (B10+MSW), the organic materials applied at a rate of 20 t ha-1, together with a treatment without fertilization (control). Biochar in the B20 treatment increased the soil C content in comparison to the control. Biochar in the B10+NPK treatment reduced soil nitrate levels compared to NPK treatment. No other benefits to soil properties, nutrient uptake or plant growth were observed with the use of biochar or any positive synergistic effect with the mixture of biochar with the other organic amendments. MSW, OMW and MWC tended to increase soil pH in comparison to the control. Most of the studies with biochar were carried out in soils with edaphic limitations or harsh environmental conditions limiting plant growth, which may have facilitated the detection of favorable effects. Under less limited soils or stressful conditions for plants, such as the ones established in this experiment, the benefits of using biochar were poor. |

Este trabajo muestra los resultados de una experiencia en macetas con olivo (Olea europaea L.), realizada en un suelo ácido y con textura franco arcillosa, cultivado durante dos estaciones de crecimiento. Se utilizaron ocho tratamientos, incluyendo fertilización mineral equivalente a 100 kg ha-1 de N, P2O5 y K2O (NPK), biochar aplicado a las dosis de 10 (B10) y 20 (B20) t ha-1, mezclas de biochar con fertilización mineral (B10+NPK) y con residuos de hongos (B10+MWC), residuos de aceite de oliva de almazaras (B10+OMW) y residuos sólidos urbanos (B10+RSU), aplicados a una tasa de 20 t ha-1, y un tratamiento sin fertilización (control). El biochar en el tratamiento B20 aumentó el contenido de C en el suelo en comparación con el control. El biochar en el tratamiento B10+NPK redujo los niveles de nitrato del suelo en comparación con el tratamiento NPK. No se registró ningún otro beneficio sobre las propiedades del suelo, la absorción de nutrientes o el crecimiento de las plantas por el uso de biochar o cualquier efecto sinérgico positivo con la mezcla de biochar con los otros correctivos orgánicos. MSW, OMW y MWC tendieron a aumentar el pH del suelo en comparación con el control. Muchos de los estudios anteriores con biochar se hicieron en suelos con limitaciones edáficas o condiciones ambientales adversas, lo que puede haber facilitado la aparición de efectos favorables. En condiciones menos estresantes para las plantas, como las establecidas en esta experiencia, los beneficios del uso del biochar parecen ser menos evidentes.O biochar tem recebido grande atenção como condicionador de solo, pois pode potencialmente sequestrar carbono (C) no solo, melhorar as propriedades físicas, químicas e biológicas do solo e promover a produtividade das culturas. Este trabalho relata os resultados de uma experiência em vasos com oliveira (Olea europaea L.), realizado em um solo ácido e de textura franco-argilosa, cultivada durante duas estações de crescimento. Oito tratamentos foram impostos, incluindo adubação mineral equivalente a 100 kg ha-1 de N, P2O5 e K2O (NPK), biochar aplicado nas doses de 10 (B10) e 20 (B20) t ha-1, misturas de biochar com adubação mineral (B10+NPK) e com composto de resíduos de cogumelos (B10+MWC), resíduos de lagar de azeite (B10+OMW) e resíduos sólidos urbanos (B10+RSU), aplicados a uma taxa de 20 t ha-1, e um tratamento sem fertilização (testemunha). O biochar no tratamento B20 aumentou o teor de C no solo em comparação à testemunha. O biochar no tratamento B10+NPK reduziu os níveis de nitrato do solo em comparação com o tratamento NPK. Nenhum outro benefício sobre as propriedades do solo, a absorção de nutrientes ou o crescimento das plantas foi registado pelo uso de biochar ou qualquer efeito sinérgico positivo com a mistura de biochar com os outros corretivos orgânicos. MSW, OMW e MWC tenderam a aumentar o pH do solo em comparação à testemunha. Muitos dos estudos anteriores com biochar foram feitos em solos com limitações edáficas ou condições ambientais adversas, o que pode ter facilitado o surgimento de efeitos favoráveis. Em condições menos stressantes para as plantas, como as estabelecidas nesta experiência, os benefícios do uso do biochar parecem ser menos evidentes.This work was funded by the INTERACT project – “Integrative Research in Environment, Agro-Chains and Technology”, no.
