Reserve Analysis in Roots allows you to know nitrogen reserves, carbohydrate reserves and phosphorus available in roots
AGQ Labs is excited to provide you with additional tools to contribute to the efficient planning of the crop’s productive cycle. We have begun to offer analysis in roots for table grapes, wine grapes, almonds, pomegranates, pistachios and fruit trees.
The lab reports are followed-up with a meeting by an AGQ Labs agronomist to interpret the results and to elaborate on fertilization programs for the season and the post-harvest period. These recommendations will vary according to the levels obtained in the results of Arginine, Starch, Phosphorus and Potassium.
To measure 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. The preferential form of nitrogen storage is expressed as Arginine concentration in roots.
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.
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 decayassociated to phosphorus deficiency aredue to the lack of energetic metabolism of the plant.
Suggested sampling periods
- 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 vines or trees.
