Quality Of Irrigation Water

Since water is an increasingly limited resource, having methods for evaluating its quality is necessary to ensure an adequate and sustainableuse for human consumption, agriculture and industry. The aim of this work was to describe agriwater software for evaluating the quality of irrigation water. The software consisted of the following stages: a) development of a database capable of hosting all the information stored in the software; b) conversion of chemical units; c) indexes calculation; and d) evaluation of performance and efficiency in data processing. The Agriwater software converts measuring units of ions to mg L-1, meq L-1 and mmol L-1, calculating the following water quality indexes: sodium absorption ratio, effective salinity, potential salinity and chloride toxicity. The result is Agriwater software, a professional tool that can handle, analyze and evaluate thousands of data in seconds in an intuitive and simple way.

Lake Bosomtwe

Abstract One of the six major meteoric lakes in the world, Lake Bosomtwe, is of great ecological significance for Ghanaians and the scientific community, most importantly for agricultural and human consumption. Water samples (n = 30) were collected to analyze the hydrogeochemical characteristics and water quality of the lake. Statistical methods including correlation, principal component, cluster analysis, Gibbs ratio, and the Piper–Trilinear diagram were used to analyze parameters. The Water Quality Index revealed that the lake water is not suitable for human consumption because measured pH, temperature, total dissolved solids, color, and bicarbonate exceeded their respective thresholds on all occasions. The calculated sodium absorption ratio (13.7–14.8) and soluble sodium percentage (94.43–95.43%) showed that the lake is not appropriate for irrigation as they exceeded their respective limit of 2 and 60%. The Gibbs ratio revealed that rock–water interaction is the underlying mechanism for water evolution. The Piper–Trilinear diagram revealed that alkalies earth and weak acids dominate the water chemistry of the lake. The dominant cation is sodium (82.22%), while the dominant anion is bicarbonate (79.39%). Five monitoring stations were identified, and the water quality was influenced by diverse anthropogenic and natural sources. The findings will provide a reference for policymakers and decision-makers at Lake Bosomtwe.

Quality Of Irrigation Water

Abstract The quality of untreated water used by dry season vegetable growers determines the safety of the vegetables produced for human consumption. Traditionally, small scale vegetable farmers site their farms along banks of streams which gradually dry up during the dry season resulting in isolated pockets of ponds at different intervals along the path of the streams which are used by farmers to irrigate. A field experiment was initiated at Ibadan to ascertain the quality of irrigation water used to produce vegetables along Ona-stream during the dry season. Five isolated ponds and one locally dug well were sampled and analysed to ascertain the heavy metals status. Results of soil analysis from five farms (A - E) sited very close to the stream revealed high concentrations of heavy metals ranging from 0.96 to 2.34 mg kg-1 for Pb, 0.72 to 2.16 mg kg-1 for Cr and 0.30 to 0.92 mg kg-1 for Co while farmland F sited about 90m away from the stream was free of Pb, Cr and Co contaminants. Locally dug well F water was free of Cr, Co and Pb while isolated ponds had Cr, Co and Pb in the range of 0.01 to 0.23 mg kg-1 which is beyond safe consumption thresholds. There were strong correlations between heavy metals in water and vegetable for Cr (0.992**), Cd (0.599**), Ni (0.614*) and Pb (0.552**) indicating that the hygienic status of dry season vegetables is largely determined by the quality of irrigation water. In addition, all vegetables irrigated with untreated isolated ponds contained Cd, Pb and Ni concentrations above maximum permissible standard which could pose risk to human health. Therefore, farmers should be enlightened on the need to use hygienic water for irrigation. Construction of shallow wells on the farms instead of using contaminated stream water directly could be a better option for healthy and sustainable agriculture.

AbstractDeterioration of groundwater quality due to drastic human interventions is rising at an alarming rate particularly in lower- and middle-income countries. Yet, limited research effort has been devoted to monitoring and ascertaining groundwater quality. The present study develops a comprehensive irrigation water quality index (IWQI) for rating water quality of shallow and deep aquifers in North Kurdufan province, Sudan. The new approach is developed to overcome the deficiencies of the existing irrigation indices and coming up with a unified decision for classifying water quality for irrigation purposes. Because of these indices like permeability index (PI), sodium absorption ratio (SAR), etc., depending on specific elements, entirely subjective, as well as the great variations in their results, particularly when classifying water quality. Thus, IWQI is created based on eight indices that are generally used to evaluate irrigation water quality, plus three physicochemical parameters have been proven an impact on water quality. The analytic hierarchy process (AHP) is applied to minimize the subjectivity at assign parameter weights under multiple criteria decision analysis tools (MCDA). The spatial distribution of IWQI agrees with the spatial distribution of the most parameters. The results of our approach reveal that the majority of samples are suitable for irrigation uses for both aquifers except few wells in the confined aquifer. Also, noted that there are very variations in the irrigation indices results for classifying water quality. The comparison result showed that the new index robust, fair calculations and has best classifying of water quality.

Quality Of Irrigation Water

The effects of watering technique on container grown Lonicera tatarica L. ‘Zabelii’ and Philadelphus x virginalis Rehd. irrigated with water high in soluble salts were investigated during the 1982 and 1983 growing seasons. Hand, mini-sprinkling, and sprinkler irrigation were compared. The quality of irrigation water used in this experiment included: A) EC 0.12 mmhos/cm, pH 6.6, SAR 0.3 (city water); B) EC 1.42 mmhos/cm, pH 7.5, SAR 2.0; and C) EC 2.48 mmhos/cm, pH 7.8, SAR 2.9. Mini-sprinkling resulted in significantly greater growth of Philadelphus x virginalis when compared to sprinkler irrigation. This increase in growth was attributed to greater media moisture, prevention of leaf contact with irrigation water, and the possible leaching of salts by the spotspitter type of mini-sprinkling utilized.

Groundwater quality of Agra district has been assessed considering twelve water quality parameters viz. pH, electrical conductivity (EC), total dissolved solid (TDS), chloride (Clˉ), bicarbonate (HCO3ˉ), sulfate (SO4²ˉ), silicon (Si), iron (Fe), aluminium (Al), calcium (Ca⁺⁺), magnesium (Mg⁺⁺) and sodium (Na⁺). Data on groundwater quality of fifteen blocks of the Agra district were collected for nine years (2006-2014) from the Ground Water Department, Government of Uttar Pradesh. The data are investigated using Wilcox and Piper diagrams with the help of Aquachem 2011.1 software. The assessment on suitability of groundwater quality for the irrigation purpose is done using sodium percentage (Na%), Sodium Absorption Ratio (SAR) and Residual Sodium Carbonate (RSC) for all the blocks. The results show that groundwater of various blocks of Agra district is of Na⁺- Clˉ, Ca2⁺- Na⁺- HCO3ˉ, Ca²+ - Mg²+ - Clˉ, Ca²+ - HCO3ˉ, Ca²+ - Clˉ, Na⁺- CIˉ, Ca²+ - Mg²+ - Clˉ - SO4²ˉ and Ca²+ - Na+ - HCO3ˉ type. It is also found that the groundwater quality of the blocks Barauli Ahir, Fatehapur Sikari, Saiyan, Achhnera, Shamsabad, Khandouli, Pinahat, Jaitpur Kalan and Bah falls under very good to medium category and can be used for the irrigation purpose. However, the groundwater quality for the blocks Bichpuri, Akola, Fatehabad, Khairagarh, Etmadpur and Jagner falls under Medium to very bad category and hence cannot be used for the irrigation purpose. The outcome of the study would be helpful to the farmers, policy makers and water management authorities in planning and management of irrigation water.
