This system can automatically irrigate, fertilize and control pests while reducing costs, labor, saving energy and the environment. It can also be able to communicate with users via wireless communications, and users can also control the system via Android apps. The Smart Irrigation and Fertilization project is specially designed for poor farmers. Say no to plagiarism. Get a tailor-made essay on "Why Violent Video Games Shouldn't Be Banned"? Get Original Essay IntroductionThe continuous growth in demand for food requires the rapid improvement of food production technology of a country like Bangladesh, where the economy is mainly based on agriculture and climatic conditions are isotropic, yet we fail to fully exploit the agricultural resources. Furthermore, we misuse various types of agricultural elements and continuously pollute the environment. The main reason is the lack of knowledge and the scarcity of terrestrial water reserves. Continuous extraction of water from the land is reducing the water level due to which many lands are slowly coming into the unirrigated land areas. Another very important reason for this is due to the unplanned use of water and fertilizers, due to which a significant amount of water and fertilizers goes to waste and the fertility of the soil also decreases. Bangladesh is an agricultural country. Here mostly 70% of people are directly or indirectly connected to the agricultural system, and most of them are very poor. That's why we're building an automatic system for farmers that reduces costs and time and improves their lifestyle. Smart Irrigation and Fertilization Systems (SIFS) are an emerging technology to adjust irrigation and fertilization applications based on actual weather and soil conditions. The concept of adapting the application of irrigation and fertilization to meet prevailing climate and weather conditions is as old as irrigated agriculture. Technology to automatically control irrigation and fertilization application has been included in large-scale commercial systems for some time, but is relatively new to the small residential and commercial sectors. In recent years the number of intelligent controller products on the market has increased significantly with different manufacturers opting for different control technology solutions. Our project is based on both hardware and software. And it works automatically to irrigate and fertilize crops. Having sensors to read soil moisture and weather elements, the system automatically starts the water pump when water is low based on the humidity value. It also automatically stops the pump when there is enough water. It will automatically supply fertilizer to the field after a preset period. Irrigation: We used a soil moisture sensor to continuously read the soil and get input. This soil moisture sensor (SMS) is used to detect soil moisture or judge whether there is water around the sensor. They can be very easy to use, just insert them into the ground and then read them. With the help of this sensor, it will be possible to make the plant remind the system when the pump will be turned on or off. Fertilizations - Furthermore,we will set the program for different crops. And the system will receive input from Real Time Clock (RTC) module. When the time is right, the system will initially produce liquid fertilizer, then distribute it via a water machine. Literature Review Watering plants is usually a time-consuming activity; to be achieved in a reasonable time, it requires a large amount of human resources. Traditionally, all steps were performed by humans. Nowadays, some systems use technology to reduce the number of workers or the time needed to water plants. With such systems, control is very limited and many resources are still wasted. Water is one such resource that is overused. Mass irrigation is a method used to water the plant. This method leads to huge losses as the amount of water supplied is more than the plant needs. Another method is proper fertilization. Since our farmers are unable to accurately measure soil needs or improper use of fertilizers in the fields, it is not even necessary to grow more crops. As a result, their production costs are increasing day by day and rapidly polluting our environment. So we need technology to measure accurately based on time.SIFS is an automated system that helps farmers manage irrigation and fertilization system with modern technology. It can effectively help reduce labor costs and manage water and fertilizer waste. Project Purpose The purpose of the current project was to demonstrate a total SIFS that is an intelligent, flexible, easy-to-use yet accurate irrigation planning system at an affordable cost that takes advantage of recent technological advances in wireless networks, environmental sensors and improvements in crop modeling. System Design and Implementation Hardware and Software Requirements: Arduino, Sensors, Relay Switch, Bluetooth Module, Ethernet Screen/GSM Module AC Motor, LCD Display, “C” Programming Language, Java, XML, JSON, JavaScript, Arduino IDE Software, Android studio. The system consists of four main parts; sensing part, control section, communication section and output section. Soil moisture was detected using the YL-69 soil sensor (a resistance-type sensor). The control unit was created using the ATMega1280 microcontroller based on the Arduino platform. The output was the control unit used to control the irrigation system by turning it on and off depending on the moisture content of the soil. Two design phases were undertaken; hardware and software. The SMS (YL-69) used is the resistance sensor type. Its result is the resistance in the ground between the two SMS probes. The graph obtained is exponential. The value of soil resistance decreases with increasing water content up to a certain point. To obtain the results, the three soils were dried using a pan until all moisture content was lost. For the red earth, the black earth and the sandy earth 250 grams were measured. Water was added in 25 cm3 increments and the sensor value was recorded. The soil sensor value on dry soil was almost same for the three soils at 1021, 1022, 1020 for black soil, sandy soil and red soil respectively. By adding 50 cm3 the resistance value reduced dramatically until it reached 500. By adding more water the resistance value continued to reduce. At approximately 100 cm3 of water the reduction in soil strength was reported to be at a much slower rate..
