This document provides an overview of precision farming and its key components. It explains that precision farming utilizes technologies like GPS, GIS, yield monitors, and variable rate equipment to more precisely manage farms. This allows farmers to customize their activities based on detailed data collection and analysis of field characteristics. The benefits of precision farming include more accurate production management, analysis of varietal performance in different areas, and evaluation of strategies over multiple years.
APPLICATION OF REMOTE SENSING AND GIS IN AGRICULTURELagnajeetRoy
India is a country that depends on agriculture. Today in this era of technological supremacy, agriculture is also using different new technologies like some robotic machinery to remote sensing and Geographical Information System (GIS) for the betterment of agriculture. It is easy to get the information about that area where human cannot check the condition everyday and help in gathering the data with the help of remote sensing. Whereas GIS helps in preparation of map that shows an accurate representation of data we get through remote sensing. From disease estimation to stress factor due to water, from ground water quality index to acreage estimation in various way agriculture is being profited by the application of remote sensing and GIS in agriculture. The applications of those software or techniques are very new to the agriculture domain still much more exploration is needed in this part. New software’s are developing in different parts of the world and remote sensing. Today farmers understand the beneficiaries of these kinds of techniques to the farm field which help in increasing productivity that will help future generation as technology is hype in traditional system of farming.

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.
Precision agriculture is an art and science of utilizing innovative, site-specific techniques for management of spatial and temporal variability using affordable technologies… for enhancing output, efficiency, and profitability of agricultural production in an environmentally responsible manner
In India, agriculture is one of the major application areas of the remote sensing technology.

Rice is one of the most important crop in the world.
The main production countries are China, India, Indonesia, Bangladesh, Viet Nam. Becides the Asian countries, rice is also welcomed as staple food in South America and Africa countries.
Weed control is important in rice cultivation. Main weeds are grassy weed, broadleaf weed and sedges.
Usually, the emergence of grassy weed is ealier than other types of weeds and the damage is heavier. Echinochloa spp is a big problem as main grassy weed in rice field.
Here are some several herbicides suggested for weed control in rice field.
Control of grassy weeds: Oxaziclomefone, Bispyribac-sodium, Cyhalofop-butyl.
Control of broadleaf weed and sedges: Bentazon, Bentazon + MCPA.
Pre-emergence is a cost-effective way, here are several combinations: Bensulfuron-methyl + Metolachlor, Bensulfuron-methyl + Pretilachlor, Bensulfuron-methyl + Mefenacet.

Weed Management system is an environmentally sound system of farming using all available knowledge and tools to produce crops free of economically damaging, competitive vegetation.
At present, the farmers concentrate mainly on crop production which is subjected to a high degree of uncertainty in income and employment to the farmers. In this contest, it is imperative to evolve suitable strategy for augmenting the income of a farm.
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.
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.
