“…Universitario de Tecnología, Universidad de Burdwan en India relevan que un pH elevado afecta a los suelos con el alto valor del pH redundante en un ambiente ácido. Se cree que si el nivel de pH del suelo cae en un rango de 5,5 y 7 o un máximo de 8 es con las mejores condiciones en el agua de riego la cual para los investigadores posee un nivel alcalino y apto para el suelo (14).…”

El agua de riego en San Joaquín-Cuenca, contiene diferentes contaminantes por lo que conocerlos es fundamental para evitar problemas en salud pública. Objetivo. Determinar por métodos físico-químicos y microbiológicos, la calidad de agua en el punto de captación del canal de riego “Toma de Narváez”, San Joaquín. Materiales y Métodos. Se realizó un estudio cuantitativo no experimental. La muestra estuvo integrada por 30 muestras recolectadas durante un mes del río Tomebamba en el sector de Balzay Alto de la parroquia San Joaquín en el año 2023. Los datos obtenidos fueron tabulados en SPSS versión 26, para analizar la información se usó la estadística descriptiva e inferencial mediante el uso de tablas y gráficos. Resultados. Se analizó la media de los parámetros estudiados de las 30 muestras, en donde, los sólidos disueltos totales (SDT) obtuvieron una media de 62,45 mg/L, conductividad eléctrica (CE) de 0,087317 mho/cm, nitritos de 0,017 mg/L, pH de 6,89, coliformes fecales (E. coli) de 282,97 NMP/100ml y ausencia de huevos de parásitos. Conclusiones. Los parámetros fisicoquímicos, como microbiológicos estudiados se encuentran dentro de los valores establecidos en la norma de calidad ambiental y descarga de afluentes, establecidos en el anexo 1 del libro VI del texto unificado de legislación secundaria del Ministerio del Ambiente del Ecuador.

“…Irrigating with such water increases the root-zone pH and inhibits plant access to nutrients; Mg, Ca, P, Fe, Mn, Zn [40]. In addition, irrigation water with high pH can clog injectors and drip lines with deposits of calcium and magnesium phosphates and carbonates [41]. Sulphate is a major ion present in natural waters; its enrichment in the sampled water could have originated from chemical weathering and dissolution of highly soluble sulfate-bearing minerals found in Precambrian rocks [42].…”

“…Good quality irrigation water has circumneutral pH. Irrigation water pH influences the soil pH and consequently the absorption of macro and micronutrients by the plant [41]. Therefore, when considering nontraditional water sources for agricultural purposes, it is essential to optimise the water pH for symbiotic effects between the soil and the plant [47].…”

Nutrients and organic pollutants draining from agricultural fields are the leading sources of surface water quality impairment. Activated carbon (AC) produced from agricultural crop residues has great success in the sequestration of hazardous substances from wastewaters. This study evaluates the potential of coconut shell activated carbon for agricultural drainage water quality minimization; pH adjustment, and excess nitrate and sulphate adsorption. Agriculture drainage water samples were collected and analyzed for Electrical conductivity, Total Dissolved Solids, Chloride, Sodium, Sulphate, Bicarbonate, Nitrate – Nitrogen, and pH. Coconut shells were sourced locally and carbonized at 500°C (± 5°C) for one hour in a muffle furnace. The char produced was ground, sieved, and activated with potassium hydroxide (KOH). The porosity and morphological structures of the AC were examined using a Scanning Electron Microscope. The effect of contact time (30, 60, 90, and 120 min), temperature (20 and 40°C), and adsorbent dosage (1, 1.5, 2, and 2.5 g) were examined using batch studies. The analysis of the drainage water shows the water is highly alkaline and contains sulphate and nitrate above FAO benchmark values. The SEM analysis indicates that the stability and mesoporosity of the carbonaceous material were enhanced by KOH activation. The pH value of the treated water decreased from 9.94 (highly alkaline) to 7.92. The use of 1 g (10 g/l) of coconut shell AC has the highest amount of nitrate and sulphate per unit quantity of AC (4.1 and 2.98 mg/g respectively). The adsorption process peaked at 30 mins contact time with 99.8% and 98.8% nitrate and sulphate removal efficiency, respectively. The process is temperature dependent; nitrate adsorption performs slightly better at 40°C; sulphate adsorption at 20°C. More research effort is needed to ascertain the performance and applicability under continuous flow conditions.

The objective of project is hinged on two essential features (the time and the amount of water pressure). The automated plant irrigation and monitoring system was created efficiently get things done for farmers. This capstone project used an Arduino Board. The features of the system are based on identified needs of Ladroma's Farmland, situated in Banagbanag, Montevista, and Davao De Oro. The system was configured to measure the following (temperature, humidity, water level, soil moisture and control the flow of water) either manually or automatically. Moreover, it can also sense soil moisture and supply the exact amount of water needed. The system aims to set up a wireless sensor network to monitor the soil moisture which will send information to the system to start the water pump if the soil dries up. Furthermore, the proposed irrigation system will reduce the hassle of looking after plants. Thus, improving farmer efficiency. The system will also provide a real-time monitoring status relative to plant irrigation.
