AGQ Labs offers Arginine analysis in roots for table grapes, vineyards, almonds, pomegranates, pistachios and fruit trees
AGQ Labs provides to you the necessary technical tools to contribute better planning of the crop’s productive period. We have begun to offer Arginine analysis in roots for table grapes, vineyards, almonds, pomegranates, pistachios and fruit trees.
AGQ Labs USA offers discounts according to the number of root samples to be analyzed. The lab reports are followed-up with a meeting to interpret the results and to elaborate on fertilization programs for the season and the post-harvest. These recommendations will vary according to the levels obtained in the results of Arginine, Starch, Phosphorus and Potassium. All within a turnaround time of 10 business days.
Arginine Measurement (%)
The objective is to verify Nitrogen reserves and their availability to be metabolized. The nitrogen required for initial growth (first sprouting stage) comes from the nitrogen stored as a reserve. In vid there is a preferential form of storage that is expressed as Arginine concentration in roots.
Suggested sampling periods are as follows:
- Pre-pruning: sample extraction between 10 and 2 days prior to pruning to measure reserves. The decision to begin nitrogen fertilization will be based on this data.
- Post harvest: After the harvest is finished to measure the wear of the vine.
The purpose is to determine the carbohydrate reserves. The starch concentration in the roots gives us a clear reference of the accumulated energy (energy potential) that the plant has in its initial growth in order to be able to absorb mineral elements that require energy expenditure, such as potassium. Carbohydrates are divided into three groups:
- Structural carbohydrates: celluloses, hemicelluloses, etc.
- Simple molecules: glucose, fructose, etc.
- Carbohydrate reserve: Starch, which is insoluble, has to be split in order to be used. This is stored in the roots to be split into simple molecules or structural carbohydrates, and in this process they bind with minerals to form Arginine.
Phosphorus in Roots (%)
The objective is to know the amount of Phosphorus available during initial root growth. A low accumulation of phosphorus in the roots at the end of the dormancy can be associated with decayed vines or branches. Initial signs of decay associated to phosphorus deficiency aredue to the lack of energetic metabolism of the plant.
