GIS in agriculture helps farmers to achieve increased production and reduced costs by enabling better management of land resources. The risk of marginalization and vulnerability of small and marginal farmers, who constitute about 85% of farmers globally, also gets reduced.
Agricultural Geographic Information Systems using Geomatics Technology enable the farmers to map and project current and future fluctuations in precipitation, temperature, crop output etc.
When we think of agriculture we think of cultivation,
plant life, soil fertility, types of crops, terrestrial environment,
etc. But in today’s world we associate with agriculture terms
like climate change, irrigation facilities, technological
advancements, synthetic seeds, advanced machinery etc. In
short we are interested in how science of today can help us in
the field of agriculture. And so comes into the picture
Precision Agriculture (PA).
The general definition is information and technology
based farm management system to identify, analyze and
manage spatial and temporal variability within fields for
optimum productivity and profitability, sustainability and
protection of the land resource by minimizing the production
costs. Simply put, precision farming is an approach where
inputs are utilized in precise amounts to get increased average
yields compared to traditional cultivation techniques. Hence it
is a comprehensive system designed to optimize production
with minimal adverse impact on our terrestrial system. [1]
The three major components of precision agriculture

UNIT IV PRECISION FARMING TECHNIQUES 9
Concept and introduction of precision Farming: importance, definition, principles and concepts.
Role of GIS and GPS. Mobile mapping system and its application in precision farming. Design,
layout and installation of drip and fertigation in horticultural crops, role of commuters in developing
comprehensive systems needed in site specific management (SSM), georeferencing and
photometric correction. Sensors for information gathering, geostatistics, robotics in horticulture,
postharvest process management (PPM), remote sensing, information and data management and
crop growth models, GIS based modeling,VRT, robotics and drones in agriculturePrecision farming is also known as site-specific crop management. It merges data collection and remote sensing with Global Positioning Systems (GPS) and Geographic Information Systems (GIS) to allow farmers to respond to in-field variability with their crop management.
Farmers can get extremely precise in their crop management while not sacrificing crop yields. They can vary the amount of seed planted or fertilizer spread to not just sections of a field but by the square meter and even square centimeter of a field. This means they can place the precise amount of seed and fertilizer to optimize production based on field conditions such as soil types and moisture levels.
What is Precision Farming Used For?
Farmers use precision farming in many aspects of their farming practices to make resource management decisions based upon on-site and real-time data collected in their fields.
The earliest, and most commonly used, precision ag technique is for variable rate applications of inputs. Variable rate technology (VRT) is installed on seeders, and fertilizers and is now being added to irrigation systems like center pivot systems. Variable rate technology (VRT) allows farmers to precisely vary how much and where they apply inputs (seed, fertilizer or water) based on overlaying data sources, like soil maps, prior harvest yield maps or imagery collected from drones, and airplanes or satellites. Prior to seeding or applying an input, a farmer will run a “prescription,” aka “script,” that gives the machine being used a precise GIS-enabled map with instructions of how much input to apply at what point in the field. The farmer enables auto-steer and their GPS program in their tractor and then lets the variable rate program automatically follow the script, with no further input needed from them.
These are the notes for Precision Farming useful in the course of Bsc(agriculture & food business) from Amity university or what so ever you are in.. All the best for your degree.!

Precision Farming and Good Agricultural Practices (1).pptxNaveen Prasath
Precision agriculture (PA), as the name implies, refers to the application of precise and correct amounts of inputs like water, fertilizers, pesticides etc. at the correct time to the crop for increasing its productivity and maximizing its yields. The use of inputs (i.e. chemical fertilizers and pesticides) based on the right quantity, at the right time and in the right place.
This type of management is commonly known as “Site-Specific management”
Strictly based on Global Positioning System (GPS) i.e. unique character is precise in time and space.
Precision Farming helps findout nutrient and micro nutrient deficiency in minute areas of soils and enables application of nutrients/micro nutrients in the soil where deficiency exists. This saves money and helps soil improvement.
GPS-based applications in precision farming are being used for farm planning, field mapping, soil sampling, tractor guidance, crop scouting, variable rate applications, and yield mapping. GPS allows farmers to work during low visibility field conditions such as rain, dust, fog, and darkness.

Richard's entangled aventures in wonderlandRichard Gill
Since the loophole-free Bell experiments of 2020 and the Nobel prizes in physics of 2022, critics of Bell's work have retreated to the fortress of super-determinism. Now, super-determinism is a derogatory word - it just means "determinism". Palmer, Hance and Hossenfelder argue that quantum mechanics and determinism are not incompatible, using a sophisticated mathematical construction based on a subtle thinning of allowed states and measurements in quantum mechanics, such that what is left appears to make Bell's argument fail, without altering the empirical predictions of quantum mechanics. I think however that it is a smoke screen, and the slogan "lost in math" comes to my mind. I will discuss some other recent disproofs of Bell's theorem using the language of causality based on causal graphs. Causal thinking is also central to law and justice. I will mention surprising connections to my work on serial killer nurse cases, in particular the Dutch case of Lucia de Berk and the current UK case of Lucy Letby.
Nutraceutical market, scope and growth: Herbal drug technologyLokesh Patil
As consumer awareness of health and wellness rises, the nutraceutical market—which includes goods like functional meals, drinks, and dietary supplements that provide health advantages beyond basic nutrition—is growing significantly. As healthcare expenses rise, the population ages, and people want natural and preventative health solutions more and more, this industry is increasing quickly. Further driving market expansion are product formulation innovations and the use of cutting-edge technology for customized nutrition. With its worldwide reach, the nutraceutical industry is expected to keep growing and provide significant chances for research and investment in a number of categories, including vitamins, minerals, probiotics, and herbal supplements.
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 .

GIS features can be classified in to three categories :
Points
Lines
polygons
Refer to single place and usually considered as no dimension.
Represents the linear feature and consists of series X, Y co-
ordinate pairs with discrete beginning and ending points.
Polygons are characterized by area and perimeter and closed
features defined by set of linked lines enclosing an area.
15. GIS represents these features in different types of structure.
1. Raster Model
2. Vector Model
3. Quadree model
Fist two are most popular in GIS packages available in the market.

48. Birla Technical Services (BTS)
BTS in association with RMSI Pvt. Ltd. has been undertaking an innovative study
since the last 4 years for Basmati Export Development Foundation (BEDF),
APEDA under the Ministry of Commerce, Govt. of India.
This project includes
Crop classification
Acreage estimation
Yield forecasting
Health monitoring
Using Satellite Remote Sensing/ GIS based tools for basmati in Five states i.e.
Punjab, Haryana, Uttranchal, U.P. and J& K (covering an area of over 1,80,000 sq
km)
49. Utility of Basmati Agricultural Intelligence (AI) data
RMSI understands that AI data generated is used in different
ways:
•Industries - Use this data mainly for procurement and supply chain
•Management Boards - Use this data to streamline supply chain as well as to fix
the price in the market
•Insurance companies – Create an insurance product out of the agricultural
yield data
To create such intelligent data, RMSI followed two different aspects,
namely,
•Geospatial data validity of comparing Mandi data with remote sensing based
outputs in rice production
•Supply chain management methodology evolved from the above survey
50. Study area
Major rice growing districts from the Indian Ganges fl ood plains. This includes 13
districts each in Punjab and Haryana, 29 districts in Uttar Pradesh, 4 districts in
Uttarakhand and 2 districts of Jammu & Kashmir. Geographically, this spreads
across 25° 83’ North to 33° 07’ North latitude and 73° 87’East to 81° 86’ East
longitude covering an area of about 189,000 sq km.
Input data
The entire region was carried out using IRS P6 AWiFS satellite images with
spatial resolution of 56m. Information, from regional to local, were extracted
using medium and high resolution satellite images of IRS series 1C, 1D, P6
LISS III and LISS IV with spatial resolution of 23.5m and 5.6m, respectively.
Secondary sources of information like Survey of India Toposheet on 1:50,000 scale,
district maps
51. Methodology
SCM included Market survey, assessment, Agriculture and Land Resource
Mapping.
RMSI undertook a hybrid approach to compare and assess the accuracy of
remote sensing-based production estimation of Basmati rice for kharif 2005
against the mandis arrivals and other related sources at the end of the Kharif
season-2005.
Geo-spatial data validity
52. RS data being always higher than total supply chain sources confirms the reliability
of this data. Table 2 gives the results so produced and the comparison analysis.
53. 31st March 2006 and considering certain calculated and
logical assumptions and limitations, it is concluded that
the remote sensing based estimated results for Kharif
2005 is matching up to an accuracy of 90% to 94% in the
states of the study area.
54. Space-borne of remote sensing data for crop
acreage estimation and production forecasting was
experimented in early 1980s in selected districts for wheat,
rice and groundnut to estimate state-levels wheat acreage
using Landsat MSS data for Haryana and Punjab in 1985-
86. The results were encouraging and the project namely
“Crop Acreage and Production Estimation”
Crop Acreage and Production Estimation
55. Crop Acreage and Production Estimation (CAPE)
CAPE was launched covering wheat, rice, groundnut and Rabi sorghum in
selected major growing states/districts.
SAR of RADARSAT was operationally used for kharif rice in 12 districts of
Karnataka.
The multidate WiFS data (Coarse resolution and high receptively) is used to
explore the possibility of making national level forecasts.

district in Tamilnadu with accuracy of 94% injoint venture of IIHR
56. Case IH
Advanced Farming Systems (AFS) have been at the forefront of
precision farming for more than a decade, giving farmers the ability to control
the entire crop production cycle with repeatable accuracy from sub-inch
levels and beyond, reduce overlaps and cut input costs – and maximize
your yield potential.
PRECISON SOLUTIONS FOR ALL SEASONS
58. Commercialization of PF
The interest in PF and its introduction has resulted in a gap between the
technological capabilities and scientific understanding of the relationship
between the input supplies and output products.
Issues
There are certain issues which need further attention, research and
development to deliver the best in field. The issues are as follows:
•Area coverage and data management
•Scale bias
•Infrastructure
•Ownership and privacy
59. 1.Small land holdings
2.Cost/benefit aspect of PF system
3.Heterogeneity of cropping systems
4.Lack of local technical expertise
5.Knowledge and technological gaps
In India more than 57.8 per cent of operational holdings has size less
than 1 ha.
The reasons for limited implementation of PF in Asian
countries are following:
60. Indian perspective
Several negative ecological consequences such as
•Depletion of lands,
•Decline in soil fertility,
•Soil salinization,
•Soil erosion,
•Deterioration of environment,
•Health hazards,
•Poor sustainability of agricultural lands and
•Degradation of biodiversity.
Declining use efficiency of inputs and dwindling output–input ratio have
rendered crop production less remunerative.
The M. S. Swaminathan Research Foundation, Chennai, India has joined
hands with Israel to initiate PF on an experimental basis, including
conducting training programmes
61. Challenges for precision farming
•Identification of crops and estimation of area and
production of short duration crops grown in fragmented
land holding
•Forecasting of drought and/ floods.
•Detection of crop stress due to nutrients, pests and diseases
and quantification of their effects on crop yield.
•Automation of land evaluation procedures for a variety of
applications using GIS techniques.
•Information on sub surface horizons.
•Extending precision farming database to smaller farm size
•Estimation of depth of water in resevoirs and quality
assessment of ground water.
