Quality Of Irrigation Water

In Tunisia, golf courses are irrigated with secondary treated effluent stored in landscape impoundments. The impact of the conveyance and storage steps on the physical-chemical and biological quality of irrigation water was evaluated on three golf courses over two years. It was found that the water quality varies all along the water route, from the wastewater treatment plant up to the irrigation site: nutrient and bacteria contents decreased along the route in the three cases. This variation depends on the wastewater quality, the length of the pipes conveying water, the number of regulation reservoirs and ponds, the water residence time in pipes, reservoirs and ponds, and the operation of the ponds. The bacteriological quality of irrigation water deteriorates during the irrigation period in the three golf courses as the ponds are operated as continuous flow reactors. The results obtained in this study indicate the inability of golf water supplies, as currently managed, to properly sanitize reclaimed wastewater and meet target quality criteria recommended by WHO (1989) for water intended for recreational use. For a safe reuse of reclaimed wastewater for golf course irrigation, changes in the design and operation of the ponds should be planned or additional treatment steps provided.

Irrigation Water Quality Index

As a result of different quality standards for irrigation water and the varying ion composition, and the fact that classification of irrigation water consists of large and complex data, this study was conducted in order to find a way for combining the complex water quality data into a single value, a quality of irrigation water index (IWQI) which reflects the suitability of the water quality for irrigation. Irrigation water quality variables were divided into five groups according to Food and Agriculture Organization FAO guide. The order of the parameters were, Salinity expressed in electrical conductivity (EC), Sodium adsorption ratio (SAR), Toxicity of specific ions (boron, chloride, sodium, Toxic trace elements and Miscellaneous effects on sensitive crops (nitrates and bicarbonates and pH). Linear equations of each variable and the formulation of mathematical equations had been done to convert the actual concentration values in the classification adopted to estimate the values of the indicators (sub-indices) and then converting the actual values and different units for each variable to the estimated values under the general scheme consists of grades between (0 -100). For the purpose of calculating irrigation water quality index, a software was originated entitled IWQI program was applied to the data of the irrigation water samples for eighteen (18) locations of water sampling in the rivers: Tigris, Euphrates, Diyala and Shatt al-Arab. Results showed that the values of irrigation water quality index for the period March to December 2015 of the Tigris River were highest than the values of Euphrates River at all locations from the north to the south as it was estimated 94.38 and 88.6 in Muthana bridge site (Tigris) and sader Al- Yusufiya (Euphrates), respectively in Baghdad and reached 74.55 and 67.78 in Qurna (Tigris) and Qurna (Euphrates), respectively. Irrigation water quality index of Shatt al-Arab was at the site of Altnoma 39.78 and classified as almost unsuitable. In Diyala River, it has been observed that the impact of Rustumiya weste water station in reducing the quality of irrigation water quality index was relatively low and water in the two sites (before and after Rustumiya station) are classified as moderately suitable.

Quality Of Irrigation Water

Selected farmlands in southern Baja California, Mexico, were surveyed to determine the levels and the causes of salinization/sodication in irrigated agricultural soil. The salt dynamics observed in profiles differed from farm to farm. Low EC and high pH levels were observed in the profiles of sandy fields, because the salt composition of these soils can easily change when salts are leached by irrigation water that contains carbonates of sodium. On the other hand, high levels of salinity and sodicity were observed in the soils of clayey fields. Soil salinization/sodication is complexly interrelated with soil characteristics, the amount and composition of salts in the soil, the quantity and quality of irrigation water applied, and the irrigation methods used. Our findings indicate that irrigation water in Baja California should be supplied at a rate that is sufficient to meet crop requirements without exacerbating salt accumulation.

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.

Quality Of Irrigation Water

ENGLISHAs a source of irrigation water supplies, river plays an important role in influencing the quality of irrigation water. If the river water is used as irrigation water has been contaminated, it is directly or indirectly affect agricultural production. Suwatu River polluted waste of industrial tapioca is used as a source of water supply for irrigation of paddy fields in the Bulumanis Kidul village, Margoyoso Pati Regency. This study aims to determine the quality of irrigation water in paddy fields Bulumanis Kidul village in terms of physical parameters include Electrical Conductivity (EC), Total Dissolved Solid (TDS) and the degree of acidity (pH). This research is a descriptive case study method. Sources of data in the form are primary data from observations and laboratory testing. The results showed that the parameters EC and TDS still meet the quality standards, for pH parameters, there are two locations that do not meet the requirements according to the Government Regulation No. 82 / 2001, for water class IV are location B and D. INDONESIASebagai sumber pasokan air irigasi, sungai memegang peranan penting dalam mempengaruhi kualitas air irigasi. Apabila air sungai yang digunakan sebagai air irigasi telah tercemar, maka secara langsung maupun tidak langsung akan mempengaruhi hasil produksi pertanian. Sungai Suwatu yang tercemar limbah industri tapioka digunakan sebagai sumber pasokan air irigasi bagi lahan sawah di Desa Bulumanis Kidul, Margoyoso Pati. Penelitian ini bertujuan untuk mengetahui kualitas air irigasi pada lahan sawah Desa Bulumanis Kidul ditinjau dari parameter fisik yang meliputi Daya Hantar Listrik (DHL), padatan terlarut total (TDS) dan derajat keasaman (pH). Penelitian ini merupakan penelitian deskriptif dengan metode studi kasus. Sumber data berupa data primer dari pengamatan dan pengujian laboratorium. Hasil penelitian menunjukkan bahwa parameter DHL dan TDS masih memenuhi baku mutu, sedangkan pada parameter pH, terdapat 2 lokasi yang tidak memenuhi persyaratan menurut PP No. 82 Tahun 2001 untuk air kelas IV yaitu lokasi B dan D.
