“…Further, its relative influence compared to other wastewaters is appreciable in red soil compared to other three soils. Similar findings were reported in sewage-treated soils [30]; bio-methanated spentwash-treated soil [23] reported that continuous application of different levels of spentwash had remarkably increased the NH 4 -N in soil. Both ammoniacal nitrogen content and nitrate nitrogen content were highest in lateritic soil with all other soils coming together as second.…”

“…The nitrate concentration was observed higher at surface layer (0-15 cm) in all the soils at different pore volumes passage and decreased steadily with depth. Continuous application of different levels of spentwash had remarkably increased in the NO 3 -N in soil [23]. Like carbon fractions, nitrogen fractions also recorded higher at surface layer in all the soils under different treatments.…”

A study was conducted to evaluate the effect of bio-methanated distillery spentwash, paper mill, soft drink factory and domestic sewage wastewaters on carbon and nitrogen dynamics in red, lateritic, and black soils of north Karnataka. Application of wastewaters from different sources influenced the carbon and nitrogen fractions across treated soils. Water-soluble carbon, labile carbon and organic carbon were significantly higher in bio-methanated distillery spentwash-treated soils. Wide variations in nitrogen fractions NH 4 ? -N, NO 3 --N were recorded under the influence of different wastewaters across the treated soils. Irrespective of the soil types, content of organic carbon and nitrogen fractions followed the order bio-methanated distillery spentwash [ paper mill [ domestic wastewater C soft drink factory wastewater. Higher values of carbon and nitrogen fractions were observed in the surface layers (0-15 cm) in comparison with lower depths. Enumeration of the bacteria, fungi, actinomycetes, N 2 -fixers and P-solubilizers indicated higher microbial load in bio-methanated spentwash application followed by paper mill wastewater application. Microbial load was highly concentrated in the surface layer (0-15 cm) across the soils and wastewaters evaluated. The bacterial count in treated soils was double that of fresh water-treated soils. Among the soils used in the study, maximum bacteria, actinomycetes and P-solubilizers count were recorded in black soil under the influence of the bio-methanated spentwash.

“…As the quantity of PBSW was increased, the available N content in soil was decreased in all the three soil depths. This might be due to high COD and BOD of PBSW which resulted in immobilization of available N. The high COD and BOD can increase the temperature and immobilize the nutrients particularly N as well as depletion of oxygen in soil (Kalaiselvi and Mahimairaja, 2010). Available phosphorus: The highest pooled available P content in soil (16.21, 15.11 and 12.18 kg ha -1 ) was recorded in treatment T 4 (50% N-PBSW and remaining N and P -chemical fertilizers) at all the soil depths.…”

Abstract:A field experiment was conducted on Sawargaon series of isohyperthermic family of Vertic haplustepts to study the effect of application of primary treated biomethanated spentwash (PBSW) through irrigation on soil properties, nutrient uptake and yield of soybean -wheat cropping sequence. The bulk density and hydraulic conductivity of soil were improved in 100% recommended dose (RD) of N through PBSW with and without P chemical fertilizer at soil depths of 0-15 and 15-30 cm. The lowest soil pH, calcium carbonate and highest electrical conductivity, organic carbon, available K, exchangeable sodium (Na), exchangeable sodium percentage (ESP), cation exchange capacity (CEC), sodium adsorption ratio (SAR) and pooled bacterial, fungal and actinomycetes populations in surface (0-15 cm) soil depth were observed in 100% RD of N through PBSW + with and without P chemical fertilizer at all three soil depths (0-15, 15-30 and 30-60 cm) over the other treatments. The highest pooled available soil P was recorded in 50% RD of N through PBSW application through irrigation and remaining N and P through chemical fertilizers in all three soil depths. The significantly highest total NPK uptake by cropping sequence and highest mean Benefit : Cost (B:C) ratio of soybean and wheat was recorded in 25 % RD of N through PBSW + remaining N and P through chemical fertilizers over the rest of the treatments. The 25 % N-recommended dose of soybean and wheat crop can be replaced by application of PBSW through irrigation in sequence without disturbing soils by salt load.

Kalaiselvi et al (2010) reported that higher N availability in DSW applied soil could be due to the direct contribution of nitrogen as well as increased microbial activity due to the added organic matter. ) of soil at different incubation periods and nitrogen levels on the NO3-N concentration of soil sampled at 15-day intervals during the incubation period.…”

Currently more than 20 per cent of the world’s irrigated land is salt affected. Of that about 60 per cent are sodic soils, warranting greater attention for efficient and eco-friendly environmentally amelioration techniques. Transformation and availability of several plant nutrient elements are affected by soil sodicity. Alkali/sodic soils are to be reclaimed so as tomake nutrients available to plants optimally. A laboratory incubation study was examined to analyse the impact of various amendments, either alone or in combination with nitrogen (N) @75 kg/ha, on the physico-chemical characteristics and nitrogen dynamics in sodic soil of Kumulur village Trichy District, Tamil Nadu (pH-10.4, EC-0.40 dS, m-1, ESP-31.8). The investigation was conducted at ADAC&RI in Trichy with three replications and eight treatments in a completely randomized design. The treatments used for sodic soil reclamation utilizing a standardized procedure were Gypsum (GYP) + Green manure (GM) @ 6.5 t ha-1 (T2), Distillery spent wash (DSW) @ 5 lakhs liter-1(T4), and Green leaf manure (GLM) @ 12.5 t ha-1(T3). Soil samples were taken at 15-day intervals from the 15th to the 60th day and tested for NH4-N, NO3-N, and accessible nitrogen. Using DSW, GYP + GM, and GLM, the pH of the water was decreased from 10.2 to 8.37, 8.42, and 9.21, respectively. The soil pH dropped the most in the DSW-controlled treatments. The application of nitrogen alone without any amendments (T5) recorded a higher value (135 kg ha-1) during an initial period (15 days) only and thereafter declined sharply due to various losses, i.e., volatilization, denitrification or fixation. When nitrogen was applied along with amendments, a significant (CD-0.05%) buildup in available N contents was observed over the application of N alone. Available nitrogen (325 kg ha-1), nitrate nitrogen (102 kg ha-1) and ammonical nitrogen (205 kg ha-1) were significantly increased due to the addition of amendments. However, the decline in available N with incubation period was only marginal when nitrogen was applied along with amendments. An increase in NH4-N at 30 DAI might be due to the release of nutrients. A slight increase in the nitrate-N content of the soil was observed at the end of the incubation period due to microbial oxidation of NH4-N to NO3-N. The application of amendments could save a quantity of N dose besides reclaiming the sodicity.
