Summary: This study aimed to test whether the integration of precision farming and agroecological practices could influence wheat yield on soils with varying degrees of risk from flooding. The results showed that both agronomic practices and soil vulnerability to flooding were significant factors affecting wheat yield. The study concluded that food security on vulnerable land can only be guaranteed when precision farming and agroecological practices are coupled with water management techniques that enhance the resilience of vulnerable soils to floods.

Summary: Treated wastewater (TWW) is increasingly used for agricultural irrigation, with higher concentrations of plant nutrients N, P, and K than freshwater. However, excessive nutrient inputs can be harmful. The study developed six indices to assess TWW-irrigation sustainability and spatio-temporal trends in NPK loads, indicating the need for redistribution of high-quality TWW in specific areas and the development of local environmental standards for maximizing nutrient utilization.

Summary: Sustainable agriculture is crucial in addressing climate change and pollution. Limited use of technology in Colombia's agriculture leads to a lack of timely and accurate information for decision-making, particularly in determining nitrogen fertilizer rates. To tackle this issue, researchers have developed a fertilization rate optimization model for potato crops in Colombia, aiming to maximize yield while minimizing nitrogen emissions.

Summary: Using hyperspectral remote sensing to predict nitrogen conversion efficiency and nitrogen internal efficiency in maize hybrids showed promising results, with the ability to statistically differentiate hybrid performance based on these predictions, particularly for nitrogen internal efficiency. Lowering the spatial resolution had an impact on the hyperspectral index values, but did not noticeably affect hybrid differentiation.

Summary: This study aims to evaluate the accuracy of mobile in-field fluorescence sensor measurements in quantifying nitrogen indicators variability in maize canopy during early growth season. The results showed that fluorescence sensor can successfully differentiate the variability among different nitrogen treatments, and the accuracy is higher at the V9 stage. When combined with machine learning model, fluorescence-based indices can estimate canopy nitrogen indicators at different growth stages. Mobile fluorescence sensing can accurately determine canopy nitrogen variability in early growth stages of maize, assisting farmers in optimal nitrogen management.

Summary: The difference in soil matrix limits nutrient analysis via XRF sensors and few strategies have been proposed to mitigate this effect. This research aimed to compare different models for predicting Ca and K in agricultural soils. The results showed that all strategies allowed mitigation of the matrix effect to some extent, with excellent predictive performance. The best models for Ca and K prediction were RS2 and RF, respectively.

Summary: This study used spectroradiometry techniques with hyperspectral data to investigate the relationship between sugarcane leaf reflectance and the contents of nitrogen, phosphorus, potassium, sulfur, calcium, and magnesium. Nutritional stress was induced in sugarcane during two harvest seasons by applying limestone doses. The study identified the wavelengths correlated with each nutrient using correlation analysis and evaluated data variability using ANOSIM and PCA. The results showed that the spectral responses in the visible and red-edge regions were most sensitive to sulfur, potassium, and phosphorus deficiencies.

Summary: Nitrogen management is crucial for agricultural production, and methods to determine nitrogen levels in plants quickly and non-invasively are important for improving production systems. This research focuses on the relationship between leaf nitrogen content (LNC) and sugarcane spectral behavior, finding that green and red-edge spectral bands are reliable predictors of LNC in sugarcane. Stepwise multiple linear regression analysis (MSLR) generated better LNC estimation models when calibrated with experimental area, independent of variety.
