Terra-Sorb increases Fat Output of olive

Field Experience | Terra-Sorb®
The main objective of cultivating olive for olive mill is to extract as much oil as possible
However, it is important to keep the productive levels without affecting later productions/harvests.
Application of Terra-Sorb Foliar in the aforementioned crop, since the first tests performed, has showed positive effects in the increase of grease/fat contents in olives, maintaining a perfect balance between fruit setting and sprouting (biennial bearing).
During the past campaign, there were done test that once again confirmed efficiency of Terra-Sorb foliar. The aforementioned tests were carried out in different plantations in the Andujar zone (Jaén.)
The main parameters evaluated were olive moisture and well as its fat content and its industrial output. In the table below we present summarized the results of spraying Terra-Sorb Foliar in the aforementioned plantations in reference to industrial output:
Action of free L-α-amino acids plus other ingredients (derivates from purinic or pirimidinic bases, etc.) present in Terra-Sorb, in the increase of fat content in olives, can be explained by the existing synergy between both compounds:
• Some amino acids such as serine, isoleucine, leucine and valine are included in the formation of different lipids, as it is the case of phosphatides and fat acids of branched chain.
• There have been described also synergies related to transport of fat acids to vegetal tissues by complexes formed by amino acids, proteins and lipids (lipoproteins.)
• In periods of stress for crops (draught, low relative humidity, etc.) fat acids are converted into sugars and used by the plant as energy source. This fact originates a decrease in fat output during periods of severe draught. In these situations, the higher resistance to stress favoured by the L¬-α-amino acids included in Terra-Sorb Foliar could also explain why fat contents is higher in olive oil produced by trees treated with Terra-Sorb Foliar.
