The nutrient balance is an approach to generate fertilization recommendations, which requires less resources and time for its implementation. It is based on the fact that the fertilization dose depends on the nutrient demand by the crop, the nutrient supply by the soil and the efficiency of recovery of the nutrient applied as fertilizer. The objective was to evaluate the conceptual model of fertilization to generate nitrogen doses in corn on the Gulf Coast of Mexico. This consisted of the balance between crop nitrogen demand minus soil nitrogen supply and fertilizer efficiency in four treatments (VS-536 and V-537 C with and without fertilizer). The physiotechnical parameters evaluated in the locations of Jamapa, Paso Real and El Rincon, in the municipality of Jamapa, Veracruz were: crop demand, soil nutrient supply and fertilizer efficiency. Nitrogen demand with fertilizer was statistically superior to that without fertilizer; supply in both treatments was statistically similar. Nitrogen fertilizer efficiency was less than 50% at all three locations. Nitrogen doses estimated with the conceptual model were different in the three locations (Jamapa 85, Rincon 55, and Paso Real 72 of kg N ha-1, respectively) compared to the applied dose (150 kg N ha-1), representing an overfertilization of 44%, 64% and 52% for Jamapa, Rincon and Paso Real. It is concluded that this model allowed the generation of adequate doses of nitrogen in less time and with a lower investment.
营养平衡是一种产生施肥建议的方法，它需要较少的资源和时间来实施。它是基于这样一个事实，即施肥剂量取决于作物对养分的需求、土壤对养分的供应以及作为肥料施用的养分的回收效率。目的是评估在墨西哥海湾沿岸的玉米中产生氮剂量的施肥概念模型。这包括4个处理(VS-536和v - 537c)的作物氮需求减去土壤氮供应和肥效之间的平衡。在韦拉克鲁斯州贾帕帕市的贾帕帕、帕索雷亚尔和埃尔林孔地区进行的物理技术参数评估为:作物需求、土壤养分供应和肥料效率。施氮量在统计学上优于不施氮量;两种治疗的供给量在统计学上是相似的。三个地点的氮肥效率均低于50%。与施氮量(150 kg N ha-1)相比，利用概念模型估算的3个地点(Jamapa 85、Rincon 55和Paso Real 72分别为kg N ha-1)的氮剂量不同，表明Jamapa、Rincon和Paso Real的过量施氮量分别为44%、64%和52%。结论是，该模型可以在较短的时间内以较低的投资产生足够剂量的氮。

In the present study, an economic valuation was realized by using the contingent valuation method. This was done to aid the conservation of the forest of the watershed lagoon of Tecocomulco. The municipalities of Almoloya, Apan and Tepeapulco were chosen as a case study. 266 questionnaires were applied, determined by simple random sampling and proportional sampling. The results show than the WTP average was $13.33 monthly per person. This result was obtained by the binomial logit model. The economic value for the conservation of the forest was estimated at $539111.41 monthly. 65% of the respondent are willing to pay to preserve the forest, 85% know of the benefits by forests and 88% are aware of the environmental degradation that exists in the watershed. The variables that were statistically significant at a confidence level of 95% in the determination of the WTP are: age, education, gender and knowledge about the benefits of forest.

Rhicephalus (Boophilus) microplus ticks represent a strong problem in cattle production systems in the Mexican humid tropics. For its control, various chemical products are applied with negative implications such as bio-resistance, high costs, environmental impact and risks to people's health due to the consumption of milk and meat with product residues. The objective of this research was to evaluate the in vitro pathogenicity of Metarhizium anisopliae strains MM0801 and CD0804 on Rhicephalus (Boophilus) microplus ticks. Five concentrations 3x104, 3x105, 3x106, 3x107, 2.6x108 of conidia per milliliter of M. anisopliae were evaluated on ticks in adult stage collected live from cattle from the Catazaja dairy basin, Chiapas, Mexico. Ticks were susceptible to the entomopathogenic fungus, finding a mortality of 50% where the mean lethal concentration obtained was 6.58 x 106 conidia / ml of strain MM0801. It is concluded that M. anisopliae influences the degree of virulence of the tick, which may be an alternative for the biological control of the tick in the humid Mexican tropics.

The production of sacha inchi (Plukenetia volubilis L.) in the tropical countries of South America has increased rapidly because of the high quality and nutritional value of the oil in its Omega 3, 6 and 9 components. A review of the available literature on sacha inchi shows that most research on this promising species has been focused on oil and its derivatives, with little attention to agronomic processes, in which predetermined technology transfer models are applied and not adapted to the particular environmental, cultural and economic conditions of the production areas. This article presents a review of articles and technical reports published in Google Academic and Scopus related to the influence of climatic variations on sacha inchi production, covering the phases of germination, growth, flowering and reproduction, presence of pests and diseases, harvesting, post-harvest and oil extraction. The aim is to provide readers with an updated view of the implications of increases or decreases in temperature and rainfall for sacha inchi cultivation, which are areas of knowledge that have been little explored in this promising oilseed species.

El objetivo del presente estudio fue evaluar el ritmo reproductivo de Nannochloropsis oculata usando dos baterías experimentales y aplicando dosis únicas de 0.32 ‰ y 1 ‰ de F/2 Guillard, respectivamente; en salinidades de 33 ‰, 25 ‰, 20 ‰, 15 ‰, 10 ‰ y 5 ‰, periodos de 10 y 23 días y temperatura de 25 ºC. En un primer experimento, con 0.32 ‰ de F/2 Guillard, N. oculata presentó mayor número de cel/ml en salinidades de 33 ‰ y 25 ‰, a los 8 días de estudio, denotando la afinidad de N. oculata de reproducirse con mayor velocidad en ese rango de salinidad. La importancia del uso de F/2 Guillard fue observada usando 1‰ debido a que la microalga presenta similar número de cel/ml (P≤0.05) en concentraciones salinas de 33 ‰, 25 ‰, 20 ‰ y 15 ‰ y similar concentración a las microalgas cultivadas con 0.32 ‰ de F/2 Guillard en salinidades de 33 ‰ y 25 ‰. La capacidad de N. oculata de reproducirse en concentraciones salinas de 33 ‰, 25 ‰ y 20 ‰ y niveles bajos de nutrientes fue testado en un segundo experimento donde los resultados muestran similar número de cel/ml entre los tratamientos salinos, en ambas baterías, a los 23 días de cultivo. Nuestros resultados sugieren que N. oculata puede reproducirse con escaza concentración de nutrientes y que su metabolismo puede estar siendo mediado por la catálisis de algunas proteínas como rubisco que sirve como una importante reserva de nitrógeno, azufre y carbono.

The challenges posed by climate change to rural education in the face of negative impacts in the biodiversity and water basins that feed the Pamplonita river, the main tributary of the aqueduct of the Cucuta metropolitan area, requires the participation of all rural social actors. The study carried out between 2019 and 2020 required the following actions: a) A reconstruction of local rural knowledge related to the interaction with the environment. b) Investigate the imaginary of the peasants around the river and water as sources of life and biodiversity. c) Systematize the cultural practices of protection and care of the community's water sources. d) Resignify, from the perspective of local actors, a pedagogy for the regeneration of water basins and biodiversity in the tributaries of the Pamplonita River. The population was taken to be the inhabitants of around six (6) tributaries that feed the Pamplonita River in the Municipality of Bochalema. The research work was approached from the hermeneutics of the spaces by selecting twenty-five (25) inhabitants, who were subjected to an in-depth interview and visited their rural properties to characterise the water resources and biodiversity in situ. The results of the research will make it possible to obtain new knowledge, useful for the design of educational strategies that help to conserve biodiversity and water sources in the face of the effects of climate change.

The present work was aims to generate an sustainable alternative for the production of bioplastics as a proposal for Agroindustrial uses, taking crops from El Salvador such as potato (Solanum tuberosum) y Mandioca (Manihot esculenta Crantz) rich in starch, modifying the molecular structure by thermo-chemical process for obtain a thermoplastic starch capable to be moldable as a biodegradable film and be blended as a biocomposite. This with the objective to mitigate the pollution originate for petrochemical plastic with a high emissions of greenhouse gases and direct effects to the biodiversity, since the population growth dynamics has led the use excessive of plastics for culture and socio-economic factors, demand that will increase parallel with the food production.

The modification of the vegetal cover It´s obvious and increasing, the main causes are the different socioeconomic activities that the population develops. Climate is an essential factor in the distribution of biotic patterns of ecosystems and, in the same sense, ecosystems, through their cover, can influence climate variability. Studies that consider the change in land use, vegetation and climate are relevant to determine processes related to soil degradation, loss of biodiversity and climate variability. This study analyzed the change in land use and climate variability from 1984 to 2018 in the municipality of Chiautzingo, Puebla, Mexico from Landsat satellite images in Geographic Information Systems. Historical data from three weather stations were analyzed and through a survey of producers, information was collected on the perception of both the phenomenon of land use change and climate variability. The change in land use is related to the loss of forest area, with an annual exchange rate of -0.57%. The increase in the area devoted to protected agriculture was 310.58 hectares, which puts pressure on biotic and abiotic resources. It was also found that there is climatic variability, which is perceived by the population. It is necessary to have this analysis to identify the areas that have the greatest environmental degradation, and as a basis for planning the use and management of natural resources.

The present investigation analyzes the volatility of precipitation and temperature in Mesoamerican cities generated by climate change, using as a baseline the dynamics of the two observed climatic variables month by month; between 1971 to 1980 and 2001 to 2010, comparing them with future climate scenarios for the years 2061 to 2070. The Mesoamerican cities used in the analysis include the capital cities of the states of the Mexican southeast, Guatemala, El Salvador, Honduras, and Belize. Measuring climatic variables' volatility allows us to qualify if the distribution of rainfall and temperature is above or below the average ranges of the historical distribution of these variables. Understanding climate volatility provides a glimpse of a series of technical and political scenarios and generates concrete actions in the face of changes in long-term climate dynamics. Thus, it anticipates the effects of extreme climate events present in a region. The method empowers decision-making in public policy, particularly in urban areas where the tendency to dry and hot climates generate a series of consequences. Some consequences are i) the need to diversify drinking water sources and hydroelectric generation, ii) the effects of heat spells on the quality of life of the population, iii) the quality of sleep and productivity, and ultimately iv ) consumption of energy levels for air conditioning or refrigeration higher than current levels.
