Article
Microplastics are small plastic pieces ranging in size from 1μ to <5 mm in diameter, are water-soluble, and can be either primary as they are initially created in small sizes or secondary as they develop due to plastic degradation. Approximately 360 million tons of plastic are produced globally every year, with only 7% recycled, leaving the majorit...
Article
Plastic pollution has become a global and persistent challenge, posing threats to ecosystems and organisms. In recent years, there has been a rapid increase in scientific research focused on understanding microplastics in the soil‒plant system. This surge is primarily driven by the direct impact of microplastics on agricultural productivity and the...

Greenhouse gas emissions during aerobic composting is unavoidable, but good practices can minimize emission. Therefore, to explore the key factors influencing the release of greenhouse gas emissions during composting, the inaction of organic matter conversion, greenhouse gas emissions and bacterial community structure during co-composting with diff...
Article
The dreaded weed ipomea (Ipomea carnea), has shown promise as a versatile phytoremediator. But I. carnea plants exude several alkaloids and phenols which are harmful to plants as well as animals. Due to this, the weed imparts as much or more toxicity to the soil as it remediates. These authors have earlier found that upon being vermicomposted by Ei...
Article
Municipal wastewater sludge may be processed into biosolids and applied to farmland for crop production, rather than be disposed of in landfills. Biosolids supply plant nutrients and increase soil organic carbon but also contribute to the production of greenhouse gases (GHGs). Computational models must therefore be refined to estimate the contribut...

Ammonia (NH3) volatilization from NH3-based fertilizer and animal manure reduces their nitrogen (N) fertilizer value and is a source of environmental pollution. Mixing manure with biochar may lower NH3 volatilization from manure by adding H⁺, adsorbing mineral N, or increasing N immobilization in microbial biomass. The objective of this study was t...
Article
Surface runoff from agricultural fields is the largest non-point source of phosphorus (P) that pollutes surface water in humid temperate regions. Best management practices have attempted to reduce P loading and improve P retention in agricultural soils, but significant losses continue to occur, emphasizing the need for novel solutions. The objectiv...

Vermicomposting is a process in which earthworms are utilized to convert biodegradable organic waste into humus-like vermicast. Past work, mainly on vermicomposting of animal droppings, has shown that vermicompost is an excellent organic fertilizer and is also imbibed with pest-repellent properties. However, there is no clarity whether vermicompost...

Question
In many of the Scientific publications it was reported that biochar was produced in the muffle furnace at varying temperature. Stainless steel/aluminium box or in some cases crucibles with lid were used as container. There seems two problems: a) maintaining oxygen free conditions and b) release of syngas or separation of syngas and bio-oil from biochar.
1) How we can maintain oxygen free atmosphere in the muffle furnace.
2) What happen to the syngas and bio-oil produced during the pyrolysis process in box/ crucible. Doesn't it impact the quality of biochar in terms of its pore size, structure and surface chemistry?
Question
I have taken the GC-MS of methanolic extract of few plant samples. I need to compare the compounds abundance and concentration in same samples, prior to and after some processing. Can i justify the concentration based on abundance /intensity of peaks?
Question
I need to quantify the lignin content of plant material and their subsequent compost. Though I had taken IR spectra of both the plant material and compost I couldn't extract much of inputs. Please, suggest me some methods for isolating the lignin content and its quantification.
Question
Whether plants have available form of nutrients or in what form does the plant material possess the nutrients. If for instance i prepare a compost from the leaves litter and wish to compare the nutrient pool in initial substrate and the final compost, what methodology need to be followed. Does the initial substrate (leaves litter) too have the available nutrients as the final compost? If yes how i can estimate?
Question
Usually we make powder of a substrate and mix it with certain quantity of Kbr for taking FT-IR spectrum, but in case of paper, i am not able to make powder of paper. Please suggest me how to prepare sample for taking FT-IR spectrum of a plain paper.
Question
It has been reported in several studies that during the process of vermicomposting the nutrient concentration (micro as well as macro nutrients) in the final vermicompost increased manifold from the initial substrate. For example, if the initial substrate has the nitrogen concentration 2g/kg, and after vermicomposting it increased up to 3g/kg (as reported in some studies). Can somebody share the experiences, with what process the nutrient pool increased from initial substrate to final vermicompost.
Question
I intend to cultivate okra in field conditions for some experimentation. I need to apply all the macro and micro nutrients in the required quantities, but I am not able to find the exact quantity of nutrients required for the growth of bhindi (okra) in South India (Pondicherry). The soil have the pH 5.90 and is stated as red soil.
Question
It has been reported in few studies that vermicompost generated from different substrates differs in terms of its impact on plant growth and yield, when amended/substituted in soil or potting media. It was also reported that the positive impacts of vermicompost on plant growth and development are not purely nutrients dependent but also non nutrient elements such as humic acids and hormones.
On what grounds we can interpret the difference in the results of seed germination, plant growth and yield of a plant species grown in soil amended with vermicompost derived from cow dung and food waste and municipal waste? In fact, the plant species and even plant variety under examination was the same. Moreover, the vermicompost concentration was also the same for each type of vermicompost.
Question
It has been reported that leaf colour can indicate the amount and proportion of chlorophyll in leaves which are, in turn, closely related to plant nutrient status. Hence, leaf colour, as a function of chlorophyll content, can be used as an index to diagnose nutrient status. What can be the possible mechanism or how can we estimate or predict the nutrient content of plants by estimating the chlorophyll content. Does plant chlorophyll content have any relationship with the growth of the plant? If yes, how?
