Plant Tissue Analysis Is Good Medicine For Crops
December 22, 2016 Plant tissue analysis determines essential nutrient concentrations in sampled plant tissues, according to an article on NutrientStewardship.com. It complements a proven soil testing plan and helps identify ways to use nutrients more efficiently. Unseen nutrient imbalances or toxicities can be identified, as well. It also measures the efficacy of fertilization and nutrient programs, as well as the levels of nutrients such as, copper, iron, sulfur and others not observed in routine soil tests.
Plant nutrient levels vary depending on the stage of maturity, the part(s) sampled, hybrid or variety and environmental conditions. Sampling earlier in the season identifies deficiencies in time to make corrective nutrient applications, if needed, to help reach yield goals and manage economic risks. Late-season samples tend to offer a “mirror into the past” at how sufficiently nutrients were taken up. This “mirror” can help you plan nutrient needs for the upcoming season.
In addition, plant tissue analysis is a proven diagnostic tool to help compare nutritional variances between normal and abnormal sections of fields. No matter the crop, plant tissue analysis is worthwhile to help determine nutrient needs. As crop values continue to rise, tools such as this and soil sampling are essential to fiscal and yield success. Balancing conservation practices, input use, and tillage to achieve optimum yield and plant nutrition are approached using a holistic point of view.
Bear in mind, plant tissue analysis should not be the sole basis for making fertilizer decisions. It should be used alongside soil test results, records of lime and nutrient applications, cropping history and recent crop protectant applications.
