Rice (Oryza sativa L.) is one of the major food crops in many countries. As the cultivation of rice requires huge volume of water, long term use of Arsenic contaminated groundwater for irrigation may result in the increase of arsenic concentration in the agricultural soil and eventually accumulation in rice grains. A micro level study was conducted to investigate the transfer of arsenic from irrigation water and soil to rice plants in the arsenic affected 8 unions of Chandina upazilla, Comilla district. The level of arsenic in irrigation water (0.12±0.08 and 0.67±0.07 mg l-1) was much above the WHO permissible limit of 0.01 mg l-1 for drinking water and FAO permissible limit of 0.10 mg l-1 for irrigation water. The total soil arsenic concentrations ranged from 3.21±0.80 to 8.74±2.83 mg kg-1 dry weight of soil, which was below the maximum acceptable limit for agricultural soil of 20.0 mg kg-1 as recommended by the European Community. The accumulation of arsenic in the grain ranged from 0.12±0.04 to 0.58±0.06 mg kg-1 in Boro and 0.16±0.04 to 1.06±0.20 mg kg-1 in T. Aman. Except grain sample (T. Aman) of one union, the grains in both Boro and T. Aman of all unions did not exceed 1.0 mg kg-1 dry weight of arsenic (the permissible limit of arsenic in rice according to WHO recommendation). Thus, till now rice has remained harmless for consumption in the study area. The results clearly showed that the arsenic content in the grains of Boro rice is correlated to the intensity of arsenic contamination of irrigation water and soil. The Agriculturists 2014; 12(2) 74-82

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.

Abstract Phytoremediation is a cost-effective and ecologically friendly process that involves the use of plants to uptake, accumulate, translocate, stabilize, or degrade pollutants. The present study was conducted to demonstrate the potential of pea (Pisum sativum L. spp. sativum) cultivar Blauwschokker to phytostimulate biodiesel degradation in an agricultural soil, considering the influence of biological remediation on selected physiological parameters of plants and the amount and activity of soil microflora. Biodiesel was spiked into soil in dose of 50 g kg−1 of dry mass soil. The results of the study showed that the rate of biodiesel degradation in the vegetated soil was higher than that occurring by natural attenuation. At the same time, biodiesel showed a positive effect on the growth, development, and activity of soil bacteria and fungi. Moreover, the obtained results showed an improvement in physiological parameters of plants, including an increase in chlorophyll a and total chlorophyll content and higher relative water content in leaves in the presence of biodiesel.

Abstract The application of hydrogel in agriculture has gained a wide interest in the last decades due to the great benefits that it has provided to this sector. In Algeria, agriculture suffers from two main issues: water shortage and climate change, especially in the south of the country (Sahara), which is classified within the arid and semi-arid regions, where irrigation is based exclusively on groundwater. This paper presents an experiment of hydrogel application in agricultural soil for reducing overexploitation of groundwater used for irrigation. Hydrogels are super absorbent polymers. They are biodegradable and have the ability to absorb and retain a large amount of water. The aim of this work is to evaluate the effect of hydrogel on the efficiency of soil moisture retention through treating sandy soil with different doses of hydrogel. The results indicate that the application of hydrogel can increase the water retaining capacity of sandy soil up to 40%.

Abstract The present study investigates the phytoaccumulation factor (PF), Ecological risk index (ERI), and carcinogenic risk factor (CRs) of toxic heavy metals (THMs) i.e. As, Cd, Cr, Pb, and Ni in the agricultural soil, irrigation water, vegetables and cereals samples collected from peri-urban regions of Lucknow. The level of these metals was within the maximum allowable concentration (MAC) (FAO/WHO 2011) in agricultural soil while it was higher in irrigation water. The phytoaccumulation factor of Cd and Ni was very high in the edible parts of vegetable and cereal samples which show that they might have entered through metal-contaminated irrigation water even if not available in the soil. The contamination coefficient (ifC) and Ecological risk factor (ifE) of metals was detected in the range of low risk in all agricultural soil, whereas Ecological risk index of metals was found in the moderate risk which indicated a mild impact on the agro-ecosystem. The carcinogenic risk potential of metals was found more than the requisite value of 10-4 in tomato, spinach, and wheat samples. This study indicates that the metals possess a moderate ecological risk and high carcinogenic risk potential through the consumption of metal-contaminated vegetables and cereals grown and sold in peri-urban regions and food markets.

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.
