English to Russian Tech/Engineering Agriculture Potassium nutrition

But when we talk about potassium, we need to understand the potassium is not mobile in the soil, potassium is not usually required early on in the plant's life cycle, which is actually good.
But there is four pools of potassium with only two pools that really matter.
The mineral potassium pool and the organic potassium pool is not the main ones that the plant takes nutrients out of.
The pools the are important for the plant uptake are exchangeable K as well soil solution K. Now, it's a very interesting equilibrium that exists between this exchangeable pool and the soil solution pool.
