“…The data from this research differ from that reported by Cetre et al (2020), who found that in substrates for vitro-plants of pineapple (Ananas comosus L.) based on cocoa soil and fertile manure compost, the percentage of total N was 1.8% and 1.48%, respectively. In addition, the data from this research contrasts with the N values reported by Rosas-Patiño et al (2021), who showed that the N percentage was not affected by the mixture of soil + dolomite lime for cocoa growth with 15.06%. In the results of this research, N consumption per agave seedling expressed different levels between the substrates.…”

Mexico has 159 species of Agave spp. In the agri-food industry stand out are Agave tequilana, A. angustifolia, and A. salmiana. A limitation to producing maguey seedlings is the low availability of organic substrates that favor plant adaptation in the field. The objective was to evaluate the effect of nitrogen (N), phosphorus (P) and potassium (K) found in substrates in response to vegetative and root growth of A. salmiana in agricultural areas of Huichapan, Hidalgo, Mexico. The treatment consisted of earthworm humus (EH) and leaf compost (LC) substrates with materials from the region with different percentages of EH (100, 75, 50%), LC (5, 10%), and sand (20, 40%). The treatments were applied with 14 random replications in two phases in seeds and 40-day-seedlings. The variables evaluated were NPK amount and pH in substrates. The physiological variables measured were plant height, leaf number, stem diameter, root length, and volume. Significant differences (P?0.05) were observed in seedling physiology due to the effect of the treatment. The best agronomic responses (plant growth and root length/weight) of Agave seedlings were T5 (75% earthworm humus + 20% sand + 5% leaf-soil) and T6 (50% earthworm humus + 40% sand + 10% leaf-soil); in both treatments, the NPK percentages were different from the control (Haplic Phaeozem soil) group. The final concentration of NPK in T6 was N = 0.04%, P = 398.13 mg Kg-1 and K = 11.88 meq 100g-1. The results infer that NPK availability in soil and progressive acidification (initial pH = 8.6, final pH = 7.4) of the substrate can favorably influence the plant response. The interactions between NPK availability in the substrate and their use for a better response in maguey seedling adaptability open up new lines of research on the productive systems in the region of Huichapan, Hidalgo, Mexico.

“…In this work, it was found that the exogenous application of macronutrients through fertilization reduced the soil pH to 4.8 and increased the EC to as high as 4.67 dS m −1 . When cocoa plants grow in extremely acidic soil (pH < 5.5), they suffer physiological disorders and present damage to their morphological structures [65], and acidity increases the bioavailability of Cd in the soil solution. Additionally, soils with an EC of > 2 dS m −1 represent saline soils [66], and this causes water deficit, decreases water absorption, produces ionic imbalance, and reduces respiration and photosynthetic activity.…”

Soil Cd is absorbed by roots and accumulated in cocoa plants, which represents a problem in the commercialization of beans. In order to evaluate whether the exogenous application of macronutrients (N, N-P, N-P-K, N-P-K-S, N-P-K-S-Mg, and N-P-K-S-Mg-Ca) mitigates the absorption, translocation, and accumulation of Cd in plants, soil pH and electric conductivity, dry root and shoot biomass, leaf gas exchange, chlorophyll content, and macronutrient bioaccumulation were evaluated in two cocoa clones (CCN-51 and EET-103) grown in a greenhouse. An increase in macronutrients gradually increased the extraction capacity of Cd in both clones, with the highest Cd values being obtained with the application of N-P-K-S-Mg-Ca. Macronutrient fertilization did not affect leaf gas exchange; however, it caused significant reductions of 30, 40, and 60% in chlorophyll content, shoot, and root dry biomass, respectively. The greatest translocation of Cd from the root to the shoot was obtained with treatments that included N in clone EET-103 and Ca in clone CCN-51. Fertilization with macronutrients did not decrease the absorption and accumulation of Cd in the cocoa seedlings, because a greater removal force of Cd from the adsorption complex towards the soil solution was caused by the exogenous application of Ca and Mg and an increase in soil acidity.

“…The grouping of the soil samples was presented with a tendency to their origin rather than due to altitude or nutrient content. The general altitude of all samples ranged from 5 m to 516 m and, on average, 151.4 m. Patiño et al, 2021). On the other hand, pH values between 7 and 7.5 are related to high Cationic Exchange Capacity and, therefore, greater nutrient intake (González-Gordon et al, 2018;Argüello et al, 2019).…”

Background: Cocoa in Mexico is produced mainly in the states of Tabasco and Chiapas, where among other factors, agroecological characteristics of the region allow its cultivation. The limitation in the production of this crop is often due to the low fertility of the soil. However, only a few studies have characterized the physical and chemical properties of the soils where cocoa is produced. Objective: To characterize the physicochemical properties of the soil under cocoa plantations in Chiapas and Tabasco, Mexico. Methodology: One hundred and seven (107) soil samples distributed in different municipalities of the states of Chiapas and Tabasco were collected for the analysis of their physical and chemical properties. A multivariate analysis was performed to observe the distribution of the samples. Finally, they were grouped using a hierarchical cluster analysis to compare the grouping based on their physical and chemical properties. Results: The grouping of the soil samples was presented based on their origin rather than due to altitude or nutrient content. According to the hierarchical cluster analysis, three groups and eight subgroups were obtained. The pH between the subgroups ranged between 5.3 and 7.3. The IIIc subgroup of Tuxtla Chico and Cacahoatán (Chiapas) presented the most significant amount of organic matter. Implications: It was a challenge to explain the physical and chemical characteristics of 107 different soils; achieving correlations required a lot of statistical analysis. Conclusion: From the soils studied, it was possible to identify the nutritional ranges and group them according to location, finding that it is variable between the subgroups, however, despite the variability they managed to meet the nutrient requirements for cocoa cultivation.
