Nutrient source, management system and the age of the plantation affect soil biodiversity and chemical properties in raspberry production

Soil biodiversity is the driving force behind most soil processes. While potentially improving plant productivity and food quality, it can be negatively affected by land use management. Raspberry production part of cultural identity ‘La Comarca Andina’ placed within “Andina Patagonica” world biosphere reserve. In this study we assessed (a) chemical quality (b) microbial in raspberry as management (certified organic vs. current conventional practice), source nutrients (commercial on-farm) age plantation. We sampled twelve plots from neighboring family farms, classified according to system nutrients, based on information recovered regarding certification, type agri-food system, weeding pests control practices, fertilizers, tillage regime rate application main amendments. each plot pH, electrical conductivity (EC), C (SOC), total N, extractable P, basal respiration (SBR), indexes (Shannon, inversed Simpson Richness), bacterial community structure considering separately rows inter-rows. The effects properties varied between row inter-row. row, these factors had no properties; while SBR, Shannon index structure. Conversely, inter-row, were detected SBR (the only biological property analyzed), management, age, or their interactions EC, P N. Finally, associations found biodiversity. diversity positively correlated with SOC gradient explained 42% variability structure, likely a result long-term high amendments P-mobilizing bacteria. These findings provide initial insights performance systems practices applied farmers production, components quality.
