Abstract (English):	Peanut (Arachis hypogaea L.) production in Argentina is established on sandy soils that are naturally susceptible to degradation leading to soil properties changes linked to how soil management was done. In this context, the valorization of peanut shells, a by-product of peanut industrial processing, has sparked interest as a strategy for sustainable soil management. This study evaluated the impact of ash and biochar organic amendments, derived from peanut shells, on soil fertility, microbial communities, and crop performance. A greenhouse trial with five treatments (control, 1% and 3% ash, and 1% and 3%) biochar) was conducted over three years, assessing chemical, microbiological, phenological, and yield-related parameters. Results showed that biochar increased organic carbon (CO), total nitrogen (NT), enzymatic activity (FDA), and microbial biomass carbon and nitrogen (CBM y NBM), promoted uniform flowering and improved yield and shoot biomass, with stable effects over time. In fact, the application of 3% biochar produced, on average, a 38% increase in CO and a 33% increase in NT compared to the control treatment. The addition of 3% ash increased pH by 20% and electrical conductivity by 60%, although it showed limited effects on soil biology and productivity. Correlation analysis revealed that the microbiological properties (FDA and NBM) were strongly associated with crop yield in contrast with traditional chemical indicators. These findings underscore the significance of biological indicators to evaluate the sustainability and productivity of agricultural systems. In conclusion, the incorporation of peanut shell-derived biochar represents an effective strategy to enhance soil biological quality, optimize nutrient use, and improve crop resilience.

Abstract (Spanish):	La producción de maní (Arachis hypogaea L.), establecida en una región caracterizada por suelos arenosos y naturalmente susceptibles a procesos de degradación, plantea un escenario donde las propiedades del recurso edáfico pueden experimentar modificaciones vinculadas a condiciones de manejo. A partir de su procesamiento industrial surge el interés por valorizar sus residuos, en particular la cáscara, como estrategia de gestión sostenible del suelo. Este estudio evaluó el impacto de la aplicación de dos enmiendas orgánicas, ceniza y biochar derivadas de cáscara de maní, sobre la fertilidad del suelo, su microbiota y el rendimiento del cultivo. Se implementó un ensayo en invernadero con cinco tratamientos (testigo, ceniza 1% y 3%, biochar 1% y 3%) durante tres años, midiendo parámetros químicos, microbiológicos, fenológicos y productivos. Los resultados evidenciaron que biochar incrementó el carbono orgánico (CO), nitrógeno total (NT), actividad enzimática (FDA) y el carbono y nitrógeno de biomasa microbiana (CBM y NBM), uniformando la floración, mejorando el rendimiento y biomasa aérea, con efectos positivos a lo largo del tiempo. La aplicación de biochar al 3% produjo, en promedio, incrementos del 38% en CO y del 33% en NT en comparación con el suelo testigo. Mientras que, la adición de ceniza al 3% aumentó un 20% el pH y un 60% la conductividad eléctrica, aunque con efectos limitados sobre la biología del suelo y la productividad. El análisis de correlación indicó que las propiedades microbiológicas (FDA y NBM), se asociaron al rendimiento a diferencia de las propiedades químicas tradicionales. Estos hallazgos resaltan la importancia de utilizar las variables biológicas para evaluar la sostenibilidad y productividad de los sistemas agrícolas. En conclusión, la incorporación de biochar derivado de cáscaras de maní representa una estrategia eficaz para mejorar la calidad biológica del suelo, optimizar el uso de nutrientes y mejorar la resiliencia de los cultivos.
