Chapter 12 Plant K nutrition and K fertilizers
Plant K A Potassium content of plants 1.20-50gkg1 2. Plants take up a large amount of K. Only N is taken up more 3. In some plants(sugar beets and potatoes) K uptake is greater than n uptake
Plant K A. Potassium content of plants 1. 20-50 g kg-1 2. Plants take up a large amount of K. Only N is taken up more. 3. In some plants (sugar beets and potatoes) K uptake is greater than N uptake
Plant K B Potassium movement to roots 1. Diffusion of k to plant roots accounts for >75% of plant upta ke. The diffusion distance is very small 2.k dissolved in soil water can also reach the plant root by mass flow
1. Diffusion of K to plant roots accounts for >75% of plant uptake. The diffusion distance is very small. 2. K dissolved in soil water can also reach the plant root by mass flow. B. Potassium movement to roots Plant K
Plant K C Potassium movement in the plant 1. Mobile in the plant. Translocated from older leaves to young growing points 2. The concentration of K in the phloem sap is high. The sap can be translocated for relatively long distances in the plan either upward or downward

Plant K D. Form of potassium in plants 1 K+ remains in its ionic form in the plant(remains as K+) 2. K+ may also be bound to negative charges on the surface of plant tissue
