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.

The international community has recognized soil salinization as one of the biggest global problems when it comes to soil conservation and its fertility, where the quality of water used for irrigation is a very important factor. Institute ofSoil Science in Belgrade conducted research on the properties of agricultural soil and irrigation water sampled at locations under irrigation systems within 6 areas of central Serbia (Braničevska, Podunavska, Pomoravska, Moravička, Mačvanska,and Toplička) in the period 2015-2018. Irrigation water was sampled at the research sites, in which the parameters for assessing its quality were analyzed (pH, electrical conductivity, sodium adsorptionratio, fixed residue). Five different classifications of irrigation water, which define the degree of risk of salinization and alkalization of soil due to the use of water of a certain quality for irrigation purposes, were applied in the paper. It was observed that a number of samples fall into different classes of application possibilities for irrigation according to different classifications. In some areas, the percentage of samples where a mismatch among classifications was observed is not negligible. Worldwide, priority is given to different classifications depending on practical experience and scientific conclusions. Many factors affect the degree of risk of soil salinization that issubject to change in the conditions of climate change. Having in mind the importance and prevalence of soil salinization, we conclude that the practice of using a number of classifications and their revision over time is a positive example and useful tool in the prevention and combat against soil salinization.

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.
