One of the most common symptoms of potassium deficiency you’ll notice in plant structures other than leaves is non-uniform stretching in stalks and stems. This could be a sign of nutrient deficiency, whether it is a nitrogen, magnesium or potassium deficiency. You may have prepared the soil, watered and mulched but growth is slow, leaves are yellow or reddish, and there is poor flowering. Deficiency symptoms may vary among crops. the causes of these symptoms? is incorrect soil pH. For more information, check out my article on low-nitrogen fertilizers. So, what are It is often confused with under watering or a disease. When potassium is readily available in the soil, a plant absorb it through plasma membrane channels and high-affinity H+/K+ transporters and store it in vacuoles. With the wide variation in soil K test levels often found within fields, it is possible to have deficient soil areas in fields that overall test adequate. to a shortage of other nutrients, or even water.
