The efficient use of fertilizers is one of the pillars of LIFE PRIORAT + MONTSANT. In this sense, foliar analysis is being performed to determine the amount of nutrients the plant absorbs. It is one of the most efficient methods to understand the shortcomings of the crop and, in combination with the soil analysis, can detect nutritional deficiencies and develop appropriate fertilization plans. In this regard, it is advancing the development of a protocol of recommendations to minimize the analysis time, and today more than 200 samples from a total of 48 wineries participating in the project have been collected.
In addition, foliar analysis is essential in cases where fertigation is applied, an increasingly popular technique in our country, which allows immediate action to correct nutritional imbalances that the plant can present, incorporating through the irrigation water, nutrients required.
