This chapter provides an overview of cation exchange capacity (CEC) and its importance as an indicator of soil fertility, particularly in the assessment of grassland quality. The limitations of traditional methods are highlighted, and the need to explore more agile approaches to grassland quality assessment is emphasized. The increasing use of hyperspectral information (HSI) as an accurate tool for measuring soil properties, which promotes more effective and sustainable rangeland management, is further explored. This provides data on soil fertility and forage quality, enabling more accurate decisions. The benefits and challenges of using HSI data to estimate CEC and its potential to improve pasture and forage production will also be examined. HSI technology allows information to be collected and analyzed from reflected light at different wavelengths, providing a clear understanding of soil physical and chemical properties. In addition, a case study illustrating the estimation of CIC using hyperspectral cameras in the department of Antioquia, Colombia, is presented. The chapter emphasizes the relevance of this topic in the rangeland context and concludes with a future outlook that anticipates a change in the management and understanding of grazing systems.

“…En el uso de suelo cacao Joven, el contenido de C (3,58%) y N (0,28%) son los picos más altos, seguido del banano (C 2,56 %; N 0,22 %); esto indica que los niveles de C son altos en estos usos del suelo y bajos en N, resultado similar a los obtenidos por Barrezueta-Unda, (2019). El promedio de P (11,52 mg/kg) y K (0,5 cmol/kg) en el uso de suelo en Banano resultaron mayores a los usos de suelo Cacao Joven (6,5 mg/kg, 0,46 cmol/kg) y Maduro (10,4 mg/kg, 0,38 cmol/kg) debido al manejo agronómico y la demanda de nutrientes durante sus etapas fenológicas; Gordon, et al (2018), mencionan que se deben realizar aplicaciones frecuentes de estos nutrientes por su alta capacidad de ser removido en el proceso fisiológico de las plantas.…”

“…Likewise, soils in the Caribbean region present acidic to strongly acidic pH conditions, salinity problems, low to medium natural fertility, as well as low cation exchange capacity [66]. In the case of the Urabá region, which has the largest export banana production area in the country, they generally have acidic pH soils, with low P and Ca content, low natural fertility, low cation exchange capacity, and low values of organic matter [67]. In this way, these studies of soils from different regions of production of banana and plantain have edaphic factors predisposing to Foc TR4 based on chemical properties of the soil that have been indicated for this pathogen in different productive systems of Musaceae in the world [21,62,[68][69][70].…”

Fusarium oxysporum f. sp. cubense Tropical Race 4 (Foc TR4) (Syn. Fusarium odoratissimum) is a devastating soil-borne pathogen that infects the roots of banana plants and causes Fusarium wilt disease. Colombia is one of the world’s leading banana producers; therefore, new uncontrolled outbreaks could have serious consequences. Despite this, little is known about the susceptibility of Musaceae lands in Colombia to Foc TR4. This work presents a pioneering study on the susceptibility of Colombian soils to Foc TR4. For this, a study was carried out to characterize climatic, edaphic, and density factors of Musaceae productive systems at the Colombian level, articulated with expert criteria to map and define areas with different levels of susceptibility to Foc R4T. These criteria are typically selected based on the existing scientific literature, consultation with domain experts, and consideration of established methods for assessing soil health and disease susceptibility in Musaceae plantations. By joining the analyzed susceptibility factors, differentiated areas were generated that imply a greater or lesser predisposition to the disease. Subsequently, a validation of the classification was made with Random Forest. The results indicate that at the level of climate, soil, and farm density as a fit factor, practically 50% of the cultivated territory of Musaceae are areas high and very highly susceptible to the pathogen (572,000 km2). The results showed that from the total Musaceae area, Antioquia, Bolívar, Chocó, and Santander turned out to be the departments with the highest proportion of very high susceptibility class of the production farms. The analysis of Random Forest classification performance shows that the model has a relatively low out-of-bag (OOB) error rate (0.023). The study on the susceptibility is highly novel and original, as it represents the first systematic investigation of Foc TR4 susceptibility in Colombian soils. This paper provides important insights into the susceptibility of Musaceae lands in Colombia to Foc TR4. The study highlights the need for ongoing monitoring, containment, and control measures to prevent the spread of this deadly pathogen and protect Colombia’s important banana industry.
