Is this explanation correct?
Can't neutral ions & positively charged ions get depleted just like negatively charged ions? Please explain.

The majority of plant-available nitrogen is in the inorganic forms NH4+ and NO3- (sometimes called mineral nitrogen). Ammonium ions bind to the soil's negatively charged cation exchange complex (CEC) and behave much like other cations in the soil. Nitrate ions do not bind to the soil solids because they carry negative charges, but exist dissolved in the soil water, or precipitated as soluble salts under dry conditions
Forms of Phosphorus available for Plant Uptake. The orthophosphates, H2PO4- and HPO42-, are the primary forms of phosphorus taken up by plants. When the soil pH is less than 7.0, H2PO4- is the predominate form in the soil. Although less common, certain organic phosphorus forms can also be directly taken up by plants
