Andalucia Board launches a Web application that allows to calculate the olive water requirement.

The Board of Agriculture, Fisheries and Rural Development, through the Research Institute and Agricultural and Fisheries Training of Andalusia, has launched a new Web application called ‘Programming olive irrigation and fertilization’ which allows to calculate the crop water requiret by climate data of Agro climate Information Network of Andalusia. When no water is available and there are limitations to apply for the provision of the grant, the electricity tariff or limitation of aquifers, it is necessary to resort to deficit irrigation, where some water stress is assumed in the plantation.

The Board of Agriculture, Fisheries and Rural Development, through the Research Institute and Agricultural and Fisheries Training of Andalusia has launched a new Web application called ‘Programming olive irrigation and fertilization’ that calculates the needs irrigation in most types of crop.

As detailed in a note the Board, this Web application, which can be accessed from desktops, notebooks and adapted to other mobile devices, it is applicable to olive crop for several distance plant as the intensive and cultivation in hedge . Furthermore, difference between adults and young olive and allows the user to make a rational plan based subscriber net tree nutritional needs. This application is available on the website of the Board of Agriculture, Fisheries and Rural Development, while the platform ‘on line’ knowledge management ‘Servifapa’ offers stakeholders the instruction manual and the ability to contact the service expert for questions of management system in a short period of time counseling. This Web service is aimed at both individual farmers and technicians of Irrigation Communities, Integrated Production Associations (API), cooperatives and advisory services as possible through a single user registration, define different owners for a program irrigation and fertilization, Irrigation demands.

On the one hand, the application uses the methodology of water balance of an official manual of the United Nations for Food and Agriculture (FAO) to calculate the irrigation that best suits each holding; and in other side, the application computes the crop evapotranspiration using climatic data of Agro climate Information Network of Andalusia (RIA) that manages the Ifapa. The RIA integrates hundred automatic weather stations located in major irrigated areas of Andalusia. It also ensures that ‘Programming the irrigation and fertilization of olive’ to define the so-called optimized irrigation, one in which the olive trees grow in the absence of water stress, because including soil characteristics of the plantation, texture and depth, calculated water needs considering rainwater that land is able to store.

However, Ifapa experts consider that, even with the contribution of rainwater, in most cases there is no availability of water to apply this type of irrigation because of the limitation by the provision of the concession fee electric or limitation of aquifers. Therefore, it becomes necessary to resort to deficit irrigation, in which water stress in some planting, depending on the degree and duration, affect different way to final production is assumed. In this case, the application difference between olive and olive oil mill table, since the design of the irrigation strategy is different depending on the final destination of the harvest. If production is for the production of olive oil it is essential to ensure water supply in the fall to not adversely affect the process of formation of oil; whereas if the olive plant is intended to obtain table olives, it is crucial to avoid wrinkling the fruit, so the summer irrigation is of great importance.

Finally, the application allows the user to modify the dose previously calculated monthly irrigation to suit the actual availability of water for planting, applying the so-called, watering to the carte. This system is based on the possibility of correcting irrigation programs obtained a priori through checking the evolution of soil water content in response to the applied water.
