La separación de residuos se encuentra poco desarrollada en Latinoamérica, en los países subdesarrollados son problemas los residuos sólidos en diferentes formas, la tasa obtenida y su eliminación es insuficientes porque afecta la salud. Motivando el inicio de investigación de la fertilización con compost producido atraves de residuos sólidos orgánicos del mercado y su mayor rendimiento en cultivo vainita en Huaura. Sobre objetivo, determinar el efecto de fertilización con compost producido, residuos sólidos orgánico del mercado y su mayor rendimiento en cultivo vainita. El método, aplicado de investigación con enfoque experimental, utilizo Diseño Bloques Completamente al Azar, conteniendo 03 bloques y 05 tratamientos, designados T1 = 0, T2 = 6, T3 = 8, T4 = 10, T5 = 10 tn/ha compost obtenido con residuos de mercado. Esto se aplicó 14 días después de la siembra, evaluá...

Objetivos: determinar los efectos de metales pesados en el cultivo de maíz. Materiales y métodos: Se determinó la concentración de los metales pesados Cu, Pb, Cd, Hg., en las aguas de la cuenca baja del rio Huaura y se evaluó su acumulación y efecto en maíz amarillo duro. También se analizó el contenido del plomo en el suelo extraído con el fin de determinar el efecto residual y la movilidad de estos elementos en el suelo a lo largo del perfil. Las parcelas de maíz se regaron con una solución de plomo con concentraciones de Pb (NO3)2 al 0.005%. Por espacio de dos meses y las del área testigo con agua potable de la Universidad. Se realizó análisis descriptivo de los datos obtenidos, análisis de varianza y comparación de medias empleando la prueba de Duncan para un nivel de probabilidad del 95%. Resultados: las cantidades de plomo se encontraron distribuidas en la raíz, h...

The Moche River water is contaminated due to informal mining and other anthropogenic activities. The pollutants are primarily organic matter and heavy metals, which contribute to the water’s elevated color and turbidity levels. This contaminated water is used for irrigating surrounding areas, leading to the production of contaminated crops. Monitoring color and turbidity requires expensive instruments. In this study, a water sample was collected from the district of Poroto, located in the province of Trujillo, La Libertad region. Approximately 200 L were sampled, with a pH of 5.2 and a turbidity of 12.04 NTU. The research employs a combined treatment process involving coagulants, specifically ferric sulfate and polyaluminum chloride, followed by filtration through activated carbon. Additionally, a low-cost monitoring system using an Arduino-based turbidimeter and colorimeter is propose...

In the present study, the influence of temperature and activating agents in the production of activated carbon from peach pits was evaluated to determine the most effective removal of water hardness. To obtain experimental data, activation was carried out using a 1:1 ratio of KOH, H3PO4, ZnCl2, and H2SO4 at temperatures of 400°C, 500°C, and 600°C. The results indicate that the highest preparation yield was achieved with carbon activated by H3PO4 at 400°C, resulting in a 47% yield. In all activation cases, the surface acidity, determined by Boehm titration, exceeded the basic character. The predominant acidic character was obtained with ZnCl2 at 500°C, reaching 62.08 mol%; acid character analyses were supported by zero-charge point pH analysis. The best iodine index analysis results were 797.22 mg/g and 747.72 mg/g, obtained with ZnCl2 at 400°C and 600°C, respectively. The activate...

Organic production is nowadays more important for the care of the environment. Therefore, fresh horticultural products such as green beans produced with organic compost are healthier and are influenced by their sensory characteristics. The objective of this research was to evaluate the effect of organic compost on the biometric characteristics of fruits and leaves, texture, and sensory attributes of fresh green beans (Phaseolus vulgaris L.), as assessed by consumers. A completely randomized design (CRD) with five experimental treatments with different levels of organic compost was used. The results show the direct influence of the level of organic compost concentration on foliar characteristics, as the concentration of compost increases, its chemical properties are increased. However, there is no direct influence on biometric, firmness, physical-chemical, and color characteristics. The S...
