Greenhouse Precision farming is the break-through farming system where the state-of-the-art technology is implemented for a sustainable production, by maximizing the efficiency of the resources through information based management, using appropriate technologies suitable to the production variables such as soil, water, seed, varietal characters of the crop, agrochemical inputs , climate , etc. The efficiency of the production resources are maximized by providing precise quantities of the inputs to the crops in right composition. The decisions are made based on the information compiled on variables like soil fertility status, intake of nutrients by the plants and crop growth parameter. The inputs are provided to plants in an integrated manner where all the required nutrients are provided to the root zone instead of blanket application of major nutrients in the top soil in two or three phases of the crop growth. The information technology tools like wi-fi systems are also utilized to draw inferences in the decision making process. Further to the improved efficiency of inputs, precision techniques have its advantages in environmental and ecological aspects. The efficient utilization of inputs will lead to the less wastage and pilferage of agro chemicals to the environment like streams, ground water sources, water bodies and non-target vegetative area. Water has become the scarcest resource in farming activity with diminishing ground water levels and erratic rainfall pattern. Precision techniques enable the system to maximize the productivity from the unit quantity of water, thereby conserving the water resources to the communities. Microcontroller PIC 18 is used for data processing and controlling various operations like the amount of water, temperature control through bulb and fan. The data obtained is sent through Wi-Fi that can be seen in the website with a given domain.
