Osmotic pressure force 𝜋𝜋 = 𝑅𝑅𝑅𝑅∑ 𝑗𝑗 𝑛𝑛 𝐶𝐶𝐶𝐶 . Total compound concentration is 0,3 mol/l. Potassium concentration (K) is only 0,1 mol/l. (about 0,1 % of plant weight). Osmotic pressure is 6 times higher than atmospheric. More fertilizers > more outer concentration > more pressure Less fertilizers > less outer concentration > less pressure
