“…With the aim to evaluate the Cl − concentration and distribution in the soil profile after three years of treatment application, soil samples were collected per treatment and replicated at a 25 cm lateral distance to the stem, where nearly 86% of the coffee roots are located [ 49 ]. Samples were taken at three soil depths (10, 30, and 50 cm).…”

Chloride (Cl−) is applied in coffee at rates as a “macronutrient” in the form of muriate of potash (MOP). Potassium (K+) is one of the most demanded nutrients by the coffee plant, and MOP is one of the most used fertilizers in coffee production. No scientific evidence shows how Cl− applied with MOP influences coffee growth, nutrient uptake, and nitrogen use efficiency (NUE). In order to address these questions, a greenhouse trial over two years and a field trial over four years were conducted. The trials were designed to test the influence of variable Cl−/S ratios on biomass accumulation, nutrient uptake, and NUE. A significant effect of the Cl− rates on growth was observed under greenhouse conditions but a non-significant effect on yield under field conditions. Cl− and S significantly influenced the NUE in coffee. The results allow us to conclude that Cl− rates need to be balanced with S rates, and that Cl− applied at macronutrient rates can improve the NUE in coffee between 7 and 21% in greenhouse conditions and between 9% and 14% in field conditions, as long as the rates do not exceed 180 mg L−1 Cl− and 80 mg·L−1 S in the greenhouse and 150 kg·ha−1·year−1 Cl− and 50 kg ha−1·year−1 S in the field. With the aim to improve the NUE in coffee, the Cl− content in leaves in coffee should be lower than 0.33% of dry matter, and in soil lower than 30 mg·L−1. In practical terms, coffee farmers need to balance K-based fertilizers to avoid the excessive Cl− applications that reduce the nutrient use efficiency, especially the NUE.

“…A cada matero se adicionaron 50 kg de suelo con humedad de 44.5%, hasta una altura de 0.35 m, para un volumen de 0.044 m 3 , con lo que se procuró conservar la densidad aparente del suelo en campo (800 kg.m -3 ). También, se instalaron los sensores de potencial mátrico y temperatura del suelo marca Teros (MPS 6 y MPS 21), a una profundidad de 0.15 a 0.20 m, que corresponde al rango de profundidad del perfil del suelo, en el que la planta de café presenta el mayor número de raíces absorbentes (Rendón y Giraldo, 2019).…”

Contextualization: Water is indispensable for plant development, and its response to water deficit varies according to the species and their growth stages. Knowledge gap: The magnitude of the effect of soil water deficit on the growth of young coffee (Coffea arabica L.) plants evaluated over time is unknown. Purpose: Research was carried out to identify the effect of soil water deficit and, therefore, the sensitivity to drought in young coffee plants. Methodology: The deficit irrigation method was used. Coffee plants of the Cenicafé 1 variety were planted at three months old in cylindrical pots and conditioned for four months in mesh houses at Cenicafé - Planalto. After conditioning, the effect on plants' growth and dry matter subjected to five ranges of soil matric potential was evaluated over 140 days. Potentials ranged from -20±10 kPa (control) to -1600±100 kPa. Results and conclusions: The results showed that soil water deficit affects the growth of young coffee (C. arabica) plants, which could define C. arabica at this stage as drought sensitive. Plants subjected to the least stress and the extreme drought showed a 30% and 57% decrease in dry matter, respectively. For growth variables, the effect of water deficit was evident in the evaluations at 77, 113, and 140 days of treatment application. In all cases, the results showed differences between the extreme drought and the control of up to 30cm in height and equatorial diameter, 0.9 m2 of leaf area, 132 leaves, 3 branches, and 66 nodes. The mathematical models that explained the effect of drought on dry mass were of the logarithmic type. It was identified that for weather and soil conditions similar to those in the study, young coffee plants begin to deteriorate after 40 days of drought. With a soil matric potential close to -40 kPa, for a time of 120 days, coffee plants can lose 10% of dry mass, and when the potential exceeds -90 kPa there can be further losses in dry matter and decreases in the number of branches between the 77 and 113 days.

“…In coffee, the highest concentration of roots is found within the first 25 cm of the soil profile [55], making solarization effective for controlling soil pathogens. After removing the infected plants and residues, the management of R. pepo and R. bunodes proceeds with solarization for three months, with flipping and homogenization performed monthly [53].…”

Coffee stands as a vital pillar of Colombia’s economic prosperity, constituting approximately 7% of the nation’s agricultural GDP. Moreover, it serves as a significant contributor to national agricultural employment, with direct jobs stemming from coffee cultivation comprising 26% of the total agricultural workforce. This underscores the pivotal role coffee plays in shaping Colombia’s social and economic landscape, solidifying its position as the primary origin of mildly washed coffees for global consumers. However, Colombia’s coffee production grapples with the challenge of operating amidst persistently rainy conditions, fostering an environment conducive to fungal diseases. This, compounded by environmental, economic, commercial, and safety constraints for disease control, creates a multifaceted scenario that continuously tests disease management strategies. Addressing this complex dynamic demands a crop protection framework that seamlessly integrates efficient and sustainable methodologies. Such methodologies should prioritize outbreak prevention, cost-effectiveness, adherence to national and international regulations, and the preservation of environmental and human health. Integrated disease management emerges as a solution capable of optimizing productivity tailored to the unique conditions of each plot. By mitigating the impact of pathogens while responsibly utilizing and conserving natural resources, this approach safeguards the well-being of both producers and consumers alike.
