The document discusses biochar, a charcoal-like substance produced from biomass that can be used as a soil amendment. It defines biochar as a carbon-rich product resulting from pyrolysis of plant biomass at low oxygen levels. Common feedstocks include wood waste, crop residues, and manure. The document outlines biochar's characteristics, production methods, impacts on soil properties like cation exchange capacity and moisture retention, and factors influencing its benefits. In conclusion, biochar can improve soil quality, sequester carbon, reduce fertilizer needs and emissions, and help manage overall soil health.
Biochar is a product rich in carbon that comes from the pyrolysis of biomass, generally of vegetable origin. It is obtained by the decomposition of organic matter exposed to temperatures between 350-600°C in an atmosphere with low oxygen availability (pyrolysis), which can be slow, intermediate or fast. The objective of this review is to show how biochar (BC) can be obtained and its effects on the physicochemical properties of soils and physiological behavior of cultivated plants. However, most studies reported positive effects of biochar application on soil physical and chemical properties, soil microbial activities, plant biomass and yield, and potential reductions of soil GHG emissions. This review summarized the general findings of the impacts of biochar application on different aspects from soil physical, chemical, and microbial properties, to soil nutrient availabilities, plant growth, biomass production and yield, greenhouse gases (GHG) emissions, and soil carbon sequestration. The biochar applications in soil remediation in the past years were summarized and possible mechanisms were discussed. Finally, the potential risks of biochar application and the future research directions were analyzed to verify the mechanisms involved in biochar-soil-microbial-plant interactions for soil carbon sequestration and crop biomass and yield improvements.
Biochar is fine-grained or granular charcoal made by heating vegetative biomass, bones, manure solids, or other plant-derived organic residues in an oxygen-free or oxygen-limited environment and used as a soil amendment for agricultur- al and environmental purposes.
It is a new word to describe fine-grained, highly porous charcoal made from biological material (biomass), high in organic carbon. This excludes fossil fuel products, geological carbon and industrial synthetics (plastics).
Biochar is pyrolysed feedstock under limited or no supply of O2 (Lehmann and Joseph, 2009)
This concept comes from-Terra Preta- ancient soils of the Amazon. (Glaser et al., 2001 and 2002; Lehmann, 2007).

CAN BIOCHAR AMENDMENTS IMPROVE SOIL QUALITY AND REDUCE CO2? A Climate Change ...Jenkins Macedo
ABSTRACT
Variations in rainfall, increased mean surface temperature, persistent drought, reduced soil moisture and nutrient, and crop failures have all been evidently linked to anthropogenic-induced climate change, which impacts food security. Agricultural soils can be used to reduce atmospheric CO2 by altering the physicochemical composition of soil organic matter through biochar soil amendments. This study draws on current literature published online, in peer review journal articles, books, and conference proceedings to assess the implications of biochar soil amendments to enhance soil quality, while reducing atmospheric CO2 concentration. Building on the critical analytical approach, biochar use as soil amendments have been tested to have promising environmental potential, which improves soil quality and quantity thereby enhancing soil moisture status and reduces atmospheric CO2. Analyses of biochar amended soils in terrestrial ecosystems reduces about 12% of the total Carbon (C) emitted through anthropogenic land use change. Biochar amended soil systems are dependable in tracing and quantifying sequestered C and can stay in the soil for thousands of years. The challenge with biochar as soil amendments is the type of biomass that can yield high quality biochar through the pyrolysis process.

Studies on technological quality of sugar beets and soil parameters in relati...Agriculture Journal IJOEAR
Abstract— The aim of the studies was to determine suitability of effluent from methane digestion of organic wastes generated during processing of sugar beets for soil application at sugar beet plantations. In the paper parameters of technological value of sugar beet roots harvested from plots with standard values (i.e. optimal values for processing) which were defined by the Institute are discussed. It was shown that effluent from digestion of sugar beet pulp can be utilized as soil amendment on sugar beet plantations without any restrictions bearing in mind content of heavy metals and harmful microorganisms. Nutrients contained in studied effluent from gasifier are available for sugar beet plants at the same level as nutrients from mineral fertilizers. Determination of heavy metals in soil samples taken before and after effluent application did not reveal accumulation of harmful elements in the soil in the result of waste utilization.

Characterization of Solid Silicone Fertilizer Produced by Hydrothermal Proces...Agriculture Journal IJOEAR
Abstract— Wastes from agriculture or sewage systems have several properties, such as huge volume, high humidity, and high organic compositions. According to the past studied, sugarcane exocarp, peanut shells and rice husk contain high silicon content. Chemical conversion of biomass feedstock will enhance usage and provide value to agricultural waste. In this research, we applied hydrothermal carbonization to rice husk waste biomass to produce silicon-doped biochar carbon material. From SEM/SEX, FT-IR and XRD results, The silicon content of the synthesized carbon materials changed with increase in carbonization temperature. In addition, the averaged silicon content in carbon material was found:sugarcane exocarp to be 3.27wt %, peanut shells to be 3.01wt %, rice husks to be 7.26wt %. The silicon content of synthesized carbon materials changed with the carbonization temperature. It was speculated that due to silicon content of rice husk, peanut shells and sugarcane exocarp, Raw materials dissolve into reaction water bath and might have bonded to the surface of carbide whilst in hydrothermal carbonization processes. Silicon content of agriculture wastes through hydrothermal carbonization was found to be feasible for the production of silicon-doped Biochars carbon materials. It is suggested that this method be used for recycling of high carbon content waste material for the production of carbon materials. Recycled silicon doped biochars can be used as a base fertilizer for growing vegetables, organic soil conditioner, and also improve the added value of agriculture. Silicon containing biomasses are feasible methods for the recovery and recycling and processing of agricultural waste. Therefore, this study using agricultural waste sugarcane exocarp, peanut shells and rice husk raw carbon silicon fertilizer raw materials production, cultivation hypokalemia, hyponatremia high silicon vegetables Accord research of patients with hyperkalemia (kidney disease).

Introduction:
RNA interference (RNAi) or Post-Transcriptional Gene Silencing (PTGS) is an important biological process for modulating eukaryotic gene expression.
It is highly conserved process of posttranscriptional gene silencing by which double stranded RNA (dsRNA) causes sequence-specific degradation of mRNA sequences.
dsRNA-induced gene silencing (RNAi) is reported in a wide range of eukaryotes ranging from worms, insects, mammals and plants.
This process mediates resistance to both endogenous parasitic and exogenous pathogenic nucleic acids, and regulates the expression of protein-coding genes.
What are small ncRNAs?
micro RNA (miRNA)
short interfering RNA (siRNA)
Properties of small non-coding RNA:
Involved in silencing mRNA transcripts.
Called “small” because they are usually only about 21-24 nucleotides long.
Synthesized by first cutting up longer precursor sequences (like the 61nt one that Lee discovered).
Silence an mRNA by base pairing with some sequence on the mRNA.
Discovery of siRNA?
The first small RNA:
In 1993 Rosalind Lee (Victor Ambros lab) was studying a non- coding gene in C. elegans, lin-4, that was involved in silencing of another gene, lin-14, at the appropriate time in the
development of the worm C. elegans.
Two small transcripts of lin-4 (22nt and 61nt) were found to be complementary to a sequence in the 3' UTR of lin-14.
Because lin-4 encoded no protein, she deduced that it must be these transcripts that are causing the silencing by RNA-RNA interactions.
Types of RNAi ( non coding RNA)
MiRNA
Length (23-25 nt)
Trans acting
Binds with target MRNA in mismatch
Translation inhibition
Si RNA
Length 21 nt.
Cis acting
Bind with target Mrna in perfect complementary sequence
Piwi-RNA
Length ; 25 to 36 nt.
Expressed in Germ Cells
Regulates trnasposomes activity
MECHANISM OF RNAI:
First the double-stranded RNA teams up with a protein complex named Dicer, which cuts the long RNA into short pieces.
Then another protein complex called RISC (RNA-induced silencing complex) discards one of the two RNA strands.
The RISC-docked, single-stranded RNA then pairs with the homologous mRNA and destroys it.
THE RISC COMPLEX:
RISC is large(>500kD) RNA multi- protein Binding complex which triggers MRNA degradation in response to MRNA
Unwinding of double stranded Si RNA by ATP independent Helicase
Active component of RISC is Ago proteins( ENDONUCLEASE) which cleave target MRNA.
DICER: endonuclease (RNase Family III)
Argonaute: Central Component of the RNA-Induced Silencing Complex (RISC)
One strand of the dsRNA produced by Dicer is retained in the RISC complex in association with Argonaute
ARGONAUTE PROTEIN :
1.PAZ(PIWI/Argonaute/ Zwille)- Recognition of target MRNA
2.PIWI (p-element induced wimpy Testis)- breaks Phosphodiester bond of mRNA.)RNAse H activity.
MiRNA:
The Double-stranded RNAs are naturally produced in eukaryotic cells during development, and they have a key role in regulating gene expression .
(May 29th, 2024) Advancements in Intravital Microscopy- Insights for Preclini...Scintica Instrumentation
Intravital microscopy (IVM) is a powerful tool utilized to study cellular behavior over time and space in vivo. Much of our understanding of cell biology has been accomplished using various in vitro and ex vivo methods; however, these studies do not necessarily reflect the natural dynamics of biological processes. Unlike traditional cell culture or fixed tissue imaging, IVM allows for the ultra-fast high-resolution imaging of cellular processes over time and space and were studied in its natural environment. Real-time visualization of biological processes in the context of an intact organism helps maintain physiological relevance and provide insights into the progression of disease, response to treatments or developmental processes.
In this webinar we give an overview of advanced applications of the IVM system in preclinical research. IVIM technology is a provider of all-in-one intravital microscopy systems and solutions optimized for in vivo imaging of live animal models at sub-micron resolution. The system’s unique features and user-friendly software enables researchers to probe fast dynamic biological processes such as immune cell tracking, cell-cell interaction as well as vascularization and tumor metastasis with exceptional detail. This webinar will also give an overview of IVM being utilized in drug development, offering a view into the intricate interaction between drugs/nanoparticles and tissues in vivo and allows for the evaluation of therapeutic intervention in a variety of tissues and organs. This interdisciplinary collaboration continues to drive the advancements of novel therapeutic strategies.

4. INTRODUCTION:-
Soil health is the foundation of a vigorous and sustainable
food system. As the land is farmed, the agricultural process
disturbs the natural soil systems including nutrient cycling
and the release and uptake of nutrients.
Efficient use of biomass, available as crop residues and other
farm wastes, by converting it to a useful source of soil
amendment/nutrients is one way to manage soil health and
fertility.
Biochar is a potential soil amendment and carbon
sequestration medium. It also reduces farm waste and
improve the soil quality. 25-10-20164
5. BIOCHAR
Biochar is a fine-grained, carbon-rich, porous product
remaining after plant biomass has been subjected to thermo-
chemical conversion process (pyrolysis) at temperatures
(~350–600°C) in an environment with little or no oxygen.
It is highly porous structure & is also very variable in quality,
depending on raw material, pyrolysis conditions, whether it is
enriched with other compounds and how finely it is ground.

Physical characterization
Pyrolysis temperature is the main regulating factor which
governs characterization of biochar.
It also depends on the type of feedstock used.

25-10-2016
• The biochar prepared from rice residues showed highest CEC.
• pH of maize & pearl millet biochar was higher than that in wheat & rice biochar.
• Maize biochar was richer in major (N, P, K), secondary (Ca, Mg) and
micronutrient (Fe, Mn, Zn and Cu) contents. Wheat biochar ranked second with
respect to all the above nutrients except sulphur for which it ranked first.

13. Biochar Stove
Types- a) Top-Lit Updraft Gasifier (TLUD)
b) Anila stove
The TLUD operates as a gasifier by creating a stratified
pyrolysis regime with four basic zones: raw biomass, flaming
pyrolysis, gas combustion and charcoal combustion.
Biomass fuel is placed between the two cylinders and a fire is
ignited in the centre. Heat from the central fire pyrolyzes the
concentric ring of fuel.
The gases escape to the centre where they add to the cooking
flame as the ring of biomass turns to char.

15. BIOCHAR APPLICATION IN SOIL
Methods of application
1. By hand
2. Using a tractor propelled lime spreader
3. Deep banding of biochar in rhizosphere
4. Mixing of biochar with composts & manures
5. Line trenching and backfilling
25-10-201615
16. • Rate of application
25-10-2016
Most studies back the field application rates to be 25 tons/ha
that increased crop productivity varying with crop type with
greater increases for legume crops (30%), vegetables (29%),
and grasses (14%) compared to cereal crops corn (8%), wheat
(11%), and rice (7%).
The yield gains were attributed to the combined effect of
increased nutrient availability (P and N) and improved soil
chemical conditions resulting from the bio-solid based
amendment.

19. Biochar Influence on Soil Water Hydraulics
Biochar additions to soils had mixed results with regard to
modifying soil hydraulic conductivity (ksat ).
Some experiments have reported improvements in ksat after
biochar additions to a silt and sandy loam-textured soil,
respectively.
In contrast no significant change has been reported in ksat for
biochar applied to loam- and clay-textured soils, respectively.
25-10-201619
20. BIOCHAR INFLUENCE ON SOIL BIOTA
25-10-2016
The chemical stability of a large fraction of a given biochar
material means that microbes will not be able to readily
utilize the C as an energy source or the N and possibly other
nutrients contained in the C structure.
However, depending on the type of biochar, a fraction may
be readily leached and therefore mineralizable and in some
cases has been shown to stimulate microbial activity and
increase abundance.

22. Critical factors for maximizing the
benefits from biochar
25-10-2016
Quality of feedstock biomass
Optimum temperature for biochar production
Soil carbon level

parameters such as soil pH, cation exchange capacity and soil
water holding capacity.
It helps reduce GHG emissions and sustain carbon sequestration.
Store recalcitrant form of carbon in soil.
Helps overcome waste lands by reclamation of the soil.
