Plant Analysis - Nutrient Management | Mosaic Crop

Most designs for using plant analysis to assess nutrient status are based on the relationship between nutrient concentration and yield or growth of a plant or plant part. There are different ways to express concentration, but the most common are percent (%) and mg/kg (or part per million, or ppm).

Mechanism of Nutrient Uptake in Plants - Soil

2021-8-18 · Similarly, as nutrient anions are absorbed by the plant, more compensating cations are absorbed and/or HCO 3 ions are excreted into the soil solution in order to maintain the electron balance in the cell. Probably the H + ions and HCO 3– ions are excreted into the ‘Soil solution first in order to help solubility of nutrient elements.
