-Precision agriculture technology provides a way for adjusting production inputs based on the needs of individual areas within fields. Although precision farming (PF) infrastructures are acceptable in Iran, farmers' knowledge about PF is the main challenge for applying this technology. Most of farms in Iran are small, so the benefits of hard PF in these farms are not sufficient to justify the costs. Utilizing some low-cost and low technology tools such as chlorophyll meter and leaf color chart might be the best choices for Iran's small farms. Most of farmers are uneducated and are not familiar with PF; therefore, education is the first step for applying this technology. Because of water crisis and low watering efficiency, Variable Rate Technology and Wireless Sensor Network can be used to optimize agricultural water consumption. Size of farmlands, farmers' knowledge, and low investment in agriculture sector are the main obstacles for PF adoption in Iran.
