Agriculture is a major source of food production in our country. Growth in population increase the demand for food production and agriculture is the main source. Irrigation in agriculture is an important process that affects the development of crops. In particular, farmers visit their agricultural fields regularly to check the level of soil moisture and water is pumped by motors to irrigate their respective fields on the basis of requirements. But the limitation of protecting crops from animals becomes a major concern for yield. This works presents the protection system in addition to the automated irrigation system.

Irrigation of fraser fir (Abies fraseri) in Christmas tree production is gaining importance in the upper midwestern United States because of the intensive planting of this species out of its natural range. However, current scheduling practices rely on empirical observations with no monitoring of soil moisture and no use of automated irrigation system. The goal of this project was to design, construct, and implement a tensiometer-based automated irrigation system for fraser fir Christmas tree plantations that would (1) use existing technologies, (2) apply water based on changes in soil moisture content, (3) provide operational flexibility, and (4) interface with a computer for system changes, data collection, and system modifications. Soil tensiometers equipped with 4- to 20-milliampere transducers were installed at two drip-irrigated tree farms. Water on demand was controlled by soil moisture tension levels that triggered the stimulation of a relay wired to solenoids delivering irrigation water to the various treatments. The system functioned according to the design as expected. However, several issues associated with the need for regular maintenance of tensiometers, computer programming, and system wiring created some challenges regarding the reliability and transferability of similar system to commercial facilities.

Agriculture plays a important role in Indian economy. The main issues which are faced in farming are water deficiency and high costs expected by labours. These major issues can be solved using smart automated irrigation system. So we proposed an renesas based smart farming using solar panel. This system consists of 3 sensors temperature, soil moisture and luminosity and senses the soil level. when soil moisture is less than the threshold level, the water is pumped to the crop. Various numbers of operations are performed in the agriculture field. Very basic operation is seeding. But the present methods of seeding are problematic. The equipments which are used for seed sowing are inconvenient to handle. So there is a need to develop the system which reduce the efforts of farmers. This system introduces a efficient mechanism which aims to drop seeds at desired position with specified distance between two seeds and lines while sowing. These operations are controlled by the human using mobile using GSM. The Reneses controller passes the information which is gathered from various sensors to Amazon web server utilizing GPRS.

Automation of farm activities can transform agricultural domain from being manual and static to intelligent and dynamic leading to higher production with lesser human supervision. This paper proposes an automated irrigation system which monitors and maintains the desired soil moisture content via automatic watering. Microcontroller ATMEGA328P on Arduino Uno platform is used to implement the control unit. The setup uses soil moisture sensors which measure the exact moisture level in soil. This value enables the system to use appropriate quantity of water which avoids over/under irrigation. IOT is used to keep the farmers updated about the status of sprinklers. Information from the sensors is regularly updated on a webpage using GSM-GPRS SIM900A modem through which a farmer can check whether the water sprinklers are ON/OFF at any given time. Also, the sensor readings are transmitted to a Thing speak channel to generate graphs for analysis.

Abstract: In a developing country like India, automation plays an important role in the development and advancement of the country. In the field of irrigation, proper method of irrigation is important . At the present era, the gardeners have been using irrigation technique in India through the manual control in which the gardeners irrigate at the regular intervals. This process sometimes consumes more water or sometimes the water reaches late due to which the grass and plants get dried. Over-irrigation can increase energy consumption and water cost as well as leaching of fertilizers below the root zone, erosion, and transport of soil and chemical particles to the drainage ditches. Irrigators who monitor soil moisture levels in the field greatly increase their ability to conserve water and energy and avoid soil erosion and water pollution. The objective of this paper is to develop sensor based automated gardening system to reduce water requirement and balanced gardening in smart city projects in India. Manpower isn`t required in this system and moisture content of soil will be balanced all the time.
