Agriculture is undergoing an agroecological transition characterized by adopting new practices to reduce chemical fertilizer inputs. In this context, digestates are emerging as sustainable substitutes for mineral fertilizers. However, large-scale application of in agricultural fields requires rigorous studies evaluate their long-term effects on soil microbial communities, which crucial ecosystem functioning and resilience. This study presents provides a comparative analysis field conditions fertilization strategies combining annual applications raw digestate with biennial different organic waste products (OWPs)-biowaste compost (BIO), farmyard manure (FYM), urban sewage sludge (SLU)-and compares them combinations the same OWPs The cumulative repeated OWP applications, paired two nitrogen sources-organic (digestate) (mineral fertilizer)-were assessed through physicochemical analyses.

Abstract Intensive agriculture has increased global food production, but also impaired ecosystem services and soil biodiversity. Organic fertilization, essential to organic integrated farming, can provide numerous benefits for quality compromise the environment by polluting soils producing greenhouse gases through animal husbandry.

Soil organic matter (SOM) plays a vital role for soil quality, sustainable food production and climate change mitigation. It is common knowledge that SOM consists of different pools with varying qualities, quantities, turnover times.

Abstract Visible and near‐infrared (vis–NIR) spectroscopy is a promising technology for the analysis of different soil quality parameters. In this study, we used in‐situ vis–NIR in association with partial least squares regression to predict total mineral (nitrate + ammonium) nitrogen content, permanganate oxidizable carbon (POXC), as well ratio organic carbon‐to‐clay content agricultural soils Switzerland. These parameters can indeed be indicators response agronomic practices. To goal, number 134 samples were carbon‐, nitrogen‐ clay‐related parameters, whereas 69 nitrogen‐related We found that model successfully POXC (ratio performance interquartile range, RPIQ > 2.62, R 2 0.73, Lin's concordance correlation coefficient 0.83).
