levélanalízis

Levélanalízis, also known as leaf analysis or foliar analysis, is a diagnostic technique used to determine the nutrient status of plants. It involves collecting leaf samples from a crop and having them analyzed in a laboratory to measure the concentration of various essential nutrients. This analysis provides valuable information about the plant's nutrient uptake and can help identify deficiencies or excesses that may be affecting growth and yield.

The process typically begins with selecting the appropriate leaves at the correct stage of plant development. Factors such as the type of crop, the specific nutrient being tested, and the time of year can influence which leaves are sampled. For example, for many perennial crops, the most recently matured leaves are often chosen. After collection, the leaves are carefully prepared for analysis, which may involve washing to remove surface contaminants and drying.

The laboratory analysis then quantifies the levels of macro-nutrients like nitrogen, phosphorus, and potassium, as well as micro-nutrients such as iron, zinc, and manganese. The results are compared to established critical levels or sufficiency ranges for the specific crop. If nutrient levels fall outside these ranges, it indicates a potential issue. Based on the findings, growers can then make informed decisions about fertilizer application, adjusting rates, timing, or types of fertilizers to correct any imbalances. Levélanalízis is a proactive tool that helps optimize plant health, improve crop productivity, and reduce the risk of nutrient-related problems.
