Invariably, many agricultural soils of the world are deficient inone or more of the essential nutrients needed to support healthyplants. Acidity, alkalinity, salinity, anthropogenic processes, natureof farming, and erosion can lead to soil degradation. Additions offertilizers and /or amendments are essential for a proper nutrientsupply and maximum yields. Estimates of overall efficiency of ap-plied fertilizer have been reported to be about or lower than 50%for N, less than 10% for P, and about 40% for K. Plants that areefficient in absorption and utilization of nutrients greatly enhancethe efficiency of applied fertilizers, reducing cost of inputs, and pre-venting losses of nutrients to ecosystems. Inter- and intra-specificvariation for plant growth and mineral nutrient use efficiency (NUE)are known to be under genetic and physiological control and aremodified by plant interactions with environmental variables. Thereis need for breeding programs to focus on developing cultivarswith high NUE. Identification of traits such as nutrient absorption,transport, utilization, and mobilization in plant cultivars shouldgreatly enhance fertilizer use efficiency. The development of newcultivars with higher NUE, coupled with best management practices (BMPs) will contribute to sustainable agricultural systemsthat protect and promote soil, water and air quality. |

Despite the importance of earthworms for soil formation, more is needed to know about how Pre-Columbian modifications to soils and the landscape. Gaining a deeper understanding is essential for comprehending the historical drivers of earthworm communities and the development of effective conservation strategies in the Amazon rainforest. Human disturbance can significantly impact earthworm diversity, especially in rainforest soils, and in the particular case of the Amazonian rainforest, both recent and ancient anthropic practices may be important. Amazonian Dark Earths (ADEs) are fertile soils found throughout the Amazon Basin, created by sedentary habits and intensification patterns of pre-Colombian societies primarily developed in the second part of the Holocene period. We have sampled earthworm com-munities in three Brazilian Amazonian (ADEs) and adjacent reference soils (REF) under old and young forests and monocultures. To better assess taxonomic richness, we used morphology and the barcode region of the COI gene to identify juveniles and cocoons and delimit Molecular Operational Taxonomic Units (MOTUs). Here we suggest using Integrated Operational Taxonomical units (IOTUs) which combine both morphological and molecular data and provide a more comprehensive assessment of diversity, while MOTUs only rely on molecular data. A total of 970 individuals were collected, resulting in 51 taxonomic units (IOTUs, MOTUs, and morphospecies combined). From this total, 24 taxonomic units were unique to REF soils, 17 to ADEs, and ten were shared between both soils. The highest richness was found in old forest sites for ADEs (12 taxonomic units) and REFs (21 taxonomic units). The beta-diversity calculations reveal a high species turnover between ADEs and REF soils, providing evidence that ADEs and REFs possess distinct soil biota. Furthermore, results suggest that ADE sites, formed by Pre-Columbian human activities, conserve a high number of native species in the landscape and maintain a high abundance, despite their long-term nature.
