“…The results of Baning et al (2016) showed the effect of BR water at different concentrations on the growth of pepper plants and found to increase the number of leaves, fresh and dry weight and recommended its use on the growth of pepper (Table 2). Juwarkar et al (1988) found populations of soil bacteria, fungi, and actinomycetes increased with increasing domestic wastewater applications. An increase in Azotobacter soil population was also observed due to the wastewater application (Juwarkar et al, 1988).…”

An increase in Azotobacter soil population was also observed due to the wastewater application (Juwarkar et al, 1988). Other than for fertilizer, WRW has also been studied for its potential use as a growth media for the bacteria Bacillus thuringiensis (Blondine & Yuniarti, 2008) and an alternative media carrier for Pseudomonas fluorescence.…”

A significant wastewater source in every household is washed rice water (WRW) because it contains leached nutrients (from washing the rice prior to cooking) that could be used as fertilizer. The paper reviewed the current understanding of the potential use of WRW as a plant nutrient source. WRW was shown to increase vegetables growth, such as water spinach, pak choy, lettuce, mustard, tomato, and eggplant. Different researchers have used various amounts of WRW, and their results followed a similar trend: the higher the amount of WRW, the higher the plant growth. WRW has also been used for other purposes, such as a source of carbon for microbial growth. WRW from brown rice and white rice had nutrients ranging from 40-150, 43-16306, 51-200, 8-3574, 36-1425, 27-212, and 32-560 mg L-1 of N, P, K, Ca, Mg, S, and vitamin B1 (thiamine), respectively. Proper utilization of WRW could reduce chemical fertilizer use and prevent both surface and groundwater contamination and environmental pollution. However, only a few of the studies have compared the use of WRW with the use of conventional NPK fertilizer. The major drawback of WRW studies is that they lack depth and scope, such as determining the initial and (or) final soil physico-chemical properties or plant nutrient contents. Considering the rich nutrient content in WRW, it will impact plant growth and soil fertility when used as both irrigation water and plant nutrient source. Therefore, it is recommended that studies on WRW effect on soil microbial population, plant, and soil nutrient contents to be carried out to ascertain the sustainability of WRW use as a plant nutrient source.

“…The pH of the soil was alkaline and contain a higher amount of inorganic minerals than wastewater. The data on the pH of the soil sample is higher compared to that of Juwarkar et al (1988) and Khasim (1989). Khasim (1989) studied agricultural soil irrigated with wastewater and the pH was reported in the range of 7.5-8.6.…”

Wastewater and soil samples were collected from the industrial area of Ghaziabad City, India from January 2005 to December 2007 and were analyzed for the presence of heavy metals by atomic absorption spectrophotometry. Test samples revealed high levels of Fe, Cr, Cu, Ni, Zn, and Cd as 967.03, 34.63, 27.97, 19.7, 16.70, and 3.20 mg/L of wastewater, respectively. The concentrations of inorganic minerals were higher in the soil samples irrigated with wastewater. Total coliforms were found to be maximum (1,133x10(4) most probable number per 100 mL) during spring and summer followed by winter and postmonsoon in the wastewater samples. The microbial count in soil as well as in wastewater decreases as the metal concentration increases. The concentration 200 microg/mL of nickel and cadmium inhibits majority of the population, while, at some points, it inhibits 100% of the population. The exponential decay model for microbial count at the increasing metal concentrations indicate that asymbiotic N2 fixers were best fitted to the model. In all the seasons, the order of decline in terms of exponential decay of the population of different microbial groups in soil was asymbiotic N2 fixers>actinomycetes>fungi>aerobic heterotrophic bacteria. The different microbial groups that have different values of slope in different seasons indicate that the resistant population of microorganisms was variable with seasons.

“…The data revealed that effect of CSFs and artificial potassium fertilization on potassium content in root (%) displayed significant (P ≤ 0.05) result in wheat crop. Juwarkar et al (1993) Potassium content in soil (mg kg -1 ) Potassium content in soil was observed maximum in treatment T15 (K SOP (2.11 g) + Press Mud 1%) with the average value from three replicates, 330 mg kg -1 soil. While to the minimum side T2 (K 0 (No K addition) + Compost 0.5%) gave the least value of potassium concentration in soil valuing 278 mg kg -1 soil (Figure 5).…”

Potassium plays a critical part in series of central metabolic and physiological developments in the plant (Cakmak and Kirkby, 2008;Marschner, 1986). In plant body, its buildup rate during initial stages of development leads nitrogen buildup. So, its provision to plants looks to be pivotal for nitrogen exploitation, Abstract | Potassium (K) fertilizer is costly in Pakistan and K from soil is depleting with intensive cropping which made it necessary to find out innovative ways to conserve native K in soil. Following study was carried out to possibly find a way to overcome bioavailable potassium losses and to access the efficacy of carbon sequestering fertilizers in this regard using wheat as a test crop under aridisols. Different carbon sequestering fertilizers (CSFs) i.e., press mud, compost and fly ash were applied @ 0% (control), 0.5 and 1% of soil weight along with recommended doses of two K chemical fertilizers (SOP and MOP). After the crop was harvested, soil sampling was carried out followed by analysis in the laboratory. All collected data was statistically analyzed for interpretations. It was depicted from results that use of carbon sequestering fertilizer (press mud @ 1 %) along with commercial K fertilizer (SOP) performed superior by resulting in maximum K content in shoot (2.13 %), K content in root (1.12 %) and K content in soil (330 ppm). Similarly, highest fresh weight (42.43 g) and dry biomass (14.37 g) of wheat were also observed when SOP was used in combination with press mud as CSF. Press mud found to be most effective CSF compared to compost and fly ash.
