Abstract Organic fertilization and planting interactively regulate soil carbon (C) storage, phosphorus (P) components, and microbial respiration, providing insights for optimizing fertilization regimes in farmland.

Abstract Tomato pomace (TP) is an underutilized source of bioactive compounds with potential application in the food sector. A factorial experiment was designed to compare three culinary techniques, Thermomix®, Roner®, and traditional pan-frying, for the preparation of tomato sauces, enriched or not with TP, applying two temperatures and two cooking times. A multivariate analysis was performed on all the results obtained for the metabolites.

1 INTRODUCTION In many modern agricultural management systems, tillage is reduced because of multiple positive effects on soil structure, moisture retention, biological activity, and erosion reduction. However, the absence of tillage leads to a stratification of the soil with increases of soil organic matter at the soil surface (Alvaro-Fuentes et al., 2009), especially when organic amendments are applied.
