Software in the field of Precision Agriculture (PA) - irrigation The main aim of the project is to create easy-to-use software that will advise farmers how much and when to irrigate their crops using data from weather stations and other humidity measurement instruments installed in their fields or near them. The situation now In Greece, the use of water in agriculture with irrigation covering 85% of the total water consumption. In South Europe, farmers are irrigating their fields with empirical methods. It is known that they use much more water than necessary – about 30% more. This method has the result of a large wastefulness of water and laundering of useful soil components. The software The software belongs to the class of Precision Agriculture (PA) and irrigation in particular rational. The software will be development as a web application for all of its characteristics and as a mobile application only to give information to the farmers. The software will be very easy-to-use from farmers. The software will take data from weather stations and other humidity measurement instruments installed in the field, calculate the amount of water needed using the appropriate calculation formula every day and advise farmers if their crop needs irrigation and how much water they need. Each time the software connects with instruments and reads new data, will calculate the amount of water needed for each particular crop the farmer has assigned to each particular weather station or other measurement devices. Every farmer will have an account in the software and a record for every field and every crop they want to watch for irrigation with the software. The farmer can connect to application whenever he wants – web or mobile edition – and informed if his crops needs irrigation and the amount of water needed. Advantages of using the software Using this software, a farmer will: • reduce production costs • save water • improve product quality • protect the environment
