“…The main soils used in Yucatan Peninsula are: K'ankab lu'um (red soil) and Box lu'um (black soil) [20]. This classification comes from the Mayan language, and is widely used in the Yucatan Peninsula (southeast region in Mexico) to refer to soils of different colors [21]. The work previously conducted by Oney-Montalvo et al [22] reported that the red soils have the highest concentration of calcium (2075.28 ± 29.70 mg kg −1 ), magnesium (779.23 ± 12.71 mg kg −1 ), phosphorus (11.00 ± 2.38 mg kg −1 ), iron (6.27 ± 0.21 mg kg −1 ) and the lowest concentration of organic matter (5.16 ± 0.04%).…”

The purpose of this work was to investigate the effect of the ripening stage and type of soil on the concentration of carotenoids and vitamins in Habanero pepper (Capsicum chinense Jacq.). Pepper plants were grown in two soils named according to the Mayan classification as: K’ankab lu’um (red soil) and Box lu’um (black soil). The results of two harvests at 320 and 334 PTD (post-transplant day) showed that the ripening stage exhibited a significant effect (p < 0.05) on the concentration of carotenoids and vitamins, while the effect of the soil type was negligible. The concentration of carotenoids decreases as the ripening process of the fruit takes place, with the highest concentration of lutein (49.47 ± 0.34 mg/100 g of dry mass), β-carotene (99.92 ± 0.69 mg/100 g of dry mass) and β-cryptoxanthin (20.93 ± 0.04 mg/100 g of dry mass) in the unripe peppers. The concentration of vitamins increases as the ripening process develops, with the highest concentration of Vitamin E (9.69 ± 0.02 mg/100 g of dry mass) and Vitamin C (119.44 ± 4.72 mg/100 g of dry mass) in the ripe peppers. This knowledge could be used to select the best ripening stage to harvest Habanero peppers according to the use of the pepper and to the needs of producers/company.

Pre-Columbian food production in the Maya Lowlands was long characterized as reliant on extensive, slash-and-burn agriculture as the sole cultivation system possible in the region, given environmental limitations, with maize as the dominant crop. While aspects of this “swidden thesis” of Maya agriculture have been chipped away in recent years, there has been an underappreciation of the many forms of long-term capital investments in agriculture made by ancient Maya people. Here, we review the last three decades of research that has overturned the swidden thesis, focusing on long-term strategies. We demonstrate long-lasting agricultural investments by Maya people, in social capital including multigenerational land tenure, in cultivated capital including long-lived trees, and in landesque capital including soil amendments and landscape engineering projects, such as terracing and wetland modification.
