PRECISE FARMING[pic 1] SUBMITTED BY – ARSHDEEP SINGHROLL NO- 31SUBJECT- GPS AND ITS APPLICATIONSABSTRACT Precision farming is a management idea in farming field which is based upon detecting, quantifying and reacting to inconstancy in crops. Spatial and temporal components are associated with crop variability that makes mathematical treatments dominant. Main aim of accurate farming is the power to specify a System for management in agriculture keeping the aim of maximizing the returns on inputs in mind . The truth lies in the fact that basic ideas like the power to explore different areas of management , different areas in which practices related to management shall be applicable , for one type of plant on a singular farm spanning over an interval of time are very hard to specify. Phytogeomorphological approach is one such approach among many which relates multiple year crop growth stability to topographical terrain attributes. Phytogeomorphological approach gained popularity because the geomorphology component decides the field’s hydrology. Datasets of multiple years are now very popular that show this stability and these effects, however, there is a lot of scope which is possible in creation of such system which can assist people related to farming globally.It is true that the advancement of GPS and GNSS gave way to precision agriculture. The ability to identify accurate coordinates in a particular field grants the freedom of formation of maps of the spatial variability multiple variables equal to the number as can be measured . These variables include yield of crop, features of relief , moisture levels, pH, nitrogen levels, content of organic matter etc. Further, comparison on common base is possible by interpolation. Any decision support system that can be prepared for a farm results in the creation of recipe maps. The development of sensors which are inbuilt on the motor vehicle have the ability to measure everything from green pigment levels to plant water levels in real time, monitors of crop field mounted on GPS, creation of variable rate technology have also enabled precision agriculture.INTRODUCTION Issues concerning The main aim of Precision agriculture is to optimize management of field with respect to:Basic technique in crop: It is done by aid of matching practices of farming more closely to needs to needs of the like usage of fertilizer inputsProtection issues of environment: It is done through reduction in the environment related risks . Nitrogen’s limiting leaching comes under this;Economics : It is done through enhancement in competitiveness through by aid of better practices . Fertilizer’s effective management comes under the economics issue . A variety of information is provided by precision agriculture which is as follows:An improved record of a farm is possible;Decision-making process enhancement;It gives better traceabilityMarketing of farm products gets a major boostRelationship with landlords is enhanced and lease arrangements are improvedEnhancement in the inherent quality of farm products PROCESSPrecision agriculture is basically a multiple-stage process which uses processes to view aerial variability:Geolocation of data Field’s location geographically allows the farmer to cover data collected from study of samples of and nitrogen which is left over , and data on former crops and resistivity of soil. Locating geographically can be achieved in following ways:
A basemap is formed from aerial photography and the farm is specified onthat base map. For ensuring that the location is accurate enough quality and the resolution must be precise.While the farmer carries out work with the machinery in the farm, an inbuilt GPS receiver on the vehicle is used to specify the farm.Defining the inconstancyDifferent things are responsible for variability within and outside the field. Amounts of nitrogen , conditions prevailing, different farming practices etc are some of the factors affecting it. Important constants about the nature are provided by the indicators that are permanent in nature like indicators of soil are one of these. To check if the crop is getting destroyed or not i.e. its current status which includes stresses about nitrogen and water levels , point indicators are really useful. To achieve this data various types of sensors and the information from the weather stations is used. Analysis of soil along with the resistivity of soil makes way to accurately plot various agricultural conditions.Techniques to handle the inconstancyVarious field inputs can be adjusted by the use of these two techniques:Technique involving the probability: It is based on the study of non-kinematic factors that include past history of the farm, resistivity etc. Control approach: Data obtained from the stable factors is refreshed from time to time by:Farmer moves around the whole field to note down the current status of the leaf by aid of sensors in the machinery. Taking the mass of the fruit, noting down its biomass and seeing the levels of chlorophyll.Carefully noting down various things like water content in air, leaf or soil , diameter of the stem and the temperature.Steps to cater inconstancyManagement relating to the crop in the farm is made more useful and easier to use by advancement in the wireless information technologies. Agricultural machinery that incorporates flexible rate mechanization is needed if management of crop in the field needs to be done. for example varying the spray of various fertilizers and seeds.Precise Farming takes use of the automation of farm machinery:
