“…Thus, the nutrient exports of N and P by the biomass of the shoots and grains were calculated by the amount of biomass multiplied by the contents of these nutrients present in it (Tables 4 and 5). Soil solution was calculated by the average concentrations of N and P in the soil solution as obtained in a similar experiment by Carlos et al (2015) with a total porosity value of 0.4 cm 3 cm -3 in the layer of 0-20 cm.…”

“…Many technologies appropriate to rich and developed countries are not feasible for implementation in developing countries (Levy et al 2011). In this sense, the use of wastewater in agriculture is a low-cost and eco-friendly tool that promotes facile intake of nutrients and organic matter into the soil (Carlos et al 2015;Carlos et al 2016). This type of wastewater can be made use of for irrigation in developing countries like Brazil for reducing effluent discharges in water sources reducing the pollution problems (Drechel et al 2010).…”

“…Flood irrigation promotes numerous chemical transformations (Carlos et al 2015), soil physical changes, and microbiological effects (Ponnamperuma 1972). The ricecultivating soils in southern Brazil are at lower elevations, have poor drainage, and lack groundwater near to the surface (Streck et al 2008), requiring constant monitoring of the composition of the effluents due to their potential for groundwater contamination.…”

Treated industrial effluents have high levels of nutrients and dissolved organic matter. The irrigation of rice by flooding can increase nutrient uptake and grain yield. Therefore, this study evaluated the nutrient contents in the shoots and grain of the rice crop and also the chemical of the soil after irrigation of the crop with leachate of the treated industrial effluent. A greenhouse experiment was conducted using pots filled with 20 kg of soil in a randomized block design with three replications. The treatments consisted of control (irrigation with distilled water) and four concentrations of the leachate (25, 50, 75, and 100 %) for irrigation. At the end of the experiment, the nutrient contents in tissues of rice plants, sterility of spikelets, and grain mass were evaluated. Results showed that irrigation with the leachate at 25 % content increased the macro-and micronutrients' concentrations in the shoot biomass and grain, except for potassium and iron. Irrigation with the industrial leachate decreased tillering and grain yield; however, it increased chlorophyll content, sterility of spikelets, and sodium intake at this leachate concentration. The potassium and sodium levels and the electrical conductivity values of soils irrigated with treated industrial leachate were increased. The use of the treated leachate from industrial effluents is an alternative that reuses the nutritional load, but the volume of leachate should be limited and monitored to prevent the sodicity in the soil and problemsdue to eutrophication.

“…Furthermore, many farmers utilize poor quality water because it is abundant and free, especially for irrigating rice crop during drought periods (Jeong et al 2014). In addition, wastewater acts as an efficient fertilizer because of its content of plant nutrients such as nitrate, phosphates and organic matter (Gibbs et al 2006 andCarlos et al 2015). This practice by farmers will not disappear and itcan'tbenegligent or dealt with by imposing a prohibition on its use (Scott et al 2004).…”

The quality of irrigation water may affect soil water retention properties, especially in arid areas such as Egypt. Evaluate such an impact plays a vital role in the achieving of effective development of soil and water maintenance and management practices. Therefore, a field trial was performed to evaluate the effects of irrigation water qualities and organic manures amendment on the soil water potential as a limiting factor of crop production. The treatments consisted of all possible combinations of three types of organic manures (2 t fed-1 rice straw compost, 5 t fed-1 farmyard manure (FYM), and 2 t fed-1 rice straw compost + 5 t fed-1 FYM) beside the control and three types of irrigation water differed in salinity (EC) and sodicity (SAR Adj), that were industrial wastewater, agricultural drainage water and freshwater. The investigated treatments influenced the shape of the soil-water characteristic curves (sorption and desorption) and had considerable effects on the aggregate stability as indicated by the patterns of hysteresis phenomena. The variation of irrigation water quality had the strongest effect on modifying soil properties, especially agricultural drainage water having the highest SAR Adj then industrial wastewater with the highest EC. In addition, mixing compost with FYM is considered the best improver for soil irrigated with poor quality water under these experimental conditions.

A long‐term no‐tillage system can increase enzymatic activity and maintain bacterial richness in paddy fields

Soil management systems cause many changes in the microenvironment that directly affect activity and diversity of microorganisms. In lowlands, there is a gap in relation to the adoption of no-tillage (zero-tillage) and the impact it has on soil under cultivation of irrigated rice. This study, an in-field experiment, evaluated the microbial enzymatic activity and diversity in an Entisol cultivated with rice under different managements for 22 years. The experiment started in the 1994/95 growing season, and the treatments were no-tillage, conventional, and pregerminated management systems. After 22 years, the data obtained on most of the evaluation dates indicated that no-tillage increased microbial biomass carbon (+45%), microbial biomass nitrogen (+54%), and basal respiration (+54%). No-tillage compared to management under soil tillage (pregerminated and conventional tillage) increased the activity of β-glucosidase (+43%), acid phosphatase (+68%), diacetate fluorescein (+34%), and urease (+96%).The enzyme activity was correlated with the soil organic carbon content and particulate fraction. Despite the relatively high enzyme activity with no-tillage, bacterial richness was maintained in this soil management system. The Proteobacteria phylum has a greater abundance in the NT (43.2%) in relation to the CT (32.3%). Bacteroidetes phylum has a lower abundance in the NT (10.0%) in relation to the CT (15.2%). The Verrucomicrobia phylum has a greater abundance in NT (8.9%) in relation to CT (4.9%). The results suggest that no-tillage is an important management tool in the recovery of irrigated rice areas whose soil has undergone microbiological degradation.
