There are environmental factors that influence the "quality" of coffee: soil, altitude, water, shading, temperature, winds, precipitation. This research paper analyzed physical and chemical factors: altitude, humidity of the environment and soil, and soil pH, in three different regions such as Córdoba, Coatepec and Xico. These temperatures and humidity varied, the pH of the soil was more acidic in high and humid regions and they were also variable in the different samples, due to temperature changes. The percentage of coffee bean moisture was analyzed, as it is an important condition to consider coffee suitable for the next roasting process. Finally, the coffee roasting process of each region was carried out; using a light, medium and dark term. Subsequently, the pH of each sample of coffee ground in hot water is analyzed, however, the acidity does not refer to the level of acidity of the coffee, it should not be confused with the character of acidity. Purely chemical process, A high acidity is described as bright, while a coffee with low acidity can be described as mild, and the low, considered uninteresting. A total lack of acidity can also result in a flat coffee.

Sludge and biosolids samples were analyzed microbiologically according to NOM-004-SEMARNAT-2002, of the Intermunicipal System of Wastewater Treatment and Disposal of the municipalities of Rincon (SITRATA) for a period of 10 months in 2017, the most were found within the LMP according to regulations. In addition, it was detected that the use of peracetic acid in doses greater than 0.1 % v/v may be an alternative disinfection in its use in sludge, to reduce the microbiological load, before being used in crops. Physicochemical analyzes were performed on samples of mud and soil to determine their N and P content, finding that the solid mud has 1.19 % of N and 3.51 % of P2O5 determined on a dry basis; which correspond to high values of these macronutrients, essential for crops. Greenhouse tests were carried out with application doses of 0 to 100 percent by weight of biosolids incorporated into the soil, to measure the crop yield of radish (Raphanus sativus), onion (Allium cepa) and carrot (Daucus carota), resulting in Agronomic dose of 20 % w/w the highest yield.
