The scientific field of precision agriculture employs increasingly innovative techniques to optimize inputs, maximize profitability, and reduce environmental impact. However, obtaining a high number of soil samples is challenging in order to make precision agriculture viable. There is a trade-off between the amount of data needed and the time and resources spent to obtain these data compared to the accuracy of the maps produced with more or fewer points.

- The petroleum industry produces various wastes that are often disposed of near well locations, leading to soil and water contamination.
- This study aimed to assess barium's solubility and its distribution in a contaminated site in Mato Rico, PR, by collecting soil samples at various depths.
- Findings revealed that while the top 0-30 cm had the largest contaminated area, the highest barium concentrations were actually found between 60-90 cm, with most barium being in a non-labile, low solubility form, indicating a low environmental risk.
The Amazon Forest plays a major role in C sequestration and release. However, few regional estimates of soil organic carbon (SOC) stock in this ecoregion exist. One of the barriers to improve SOC estimates is the lack of recent soil data at high spatial resolution, which hampers the application of new methods for mapping SOC stock.

The present study aimed to evaluate the contamination level and spatial distribution of lead in disposal and destruction areas. This site was used for ammunition disposal and destruction activities for 20 years.
