Web1 dec. 2024 · Potassium concentrations in field crops vary widely depending on the site, year, fertilizer input, and plant species. In various plant species, its concentrations have been detected in the range of 0.4–4.3% (Askegaard et al. 2004).Furthermore, the most part of subcellular K + concentration is not well characterized with the exception of the cytosol … WebPlant nutrients in the soil. Soil is a major source of nutrients needed by plants for growth. The three main nutrients are nitrogen (N), phosphorus (P) and potassium (K). Together they make up the trio known as NPK. Other important nutrients are calcium, magnesium and sulfur. Plants also need small quantities of iron, manganese, zinc, copper ...
