pH Management and Plant Nutrition: Fertilizers

water-soluble fertilizers: ammoniacal nitrogen (NH4-N), nitrate nitrogen (NO3-N) and urea (Figure 1). Uptake of ammoniacal nitrogen causes the substrate-pH to decrease because H+ (acidic protons) are secreted from roots in order to balance the charges of ions inside the plant with the solution surrounding the outside of the roots. Urea is easily converted into ammoniacal nitrogen in the ...
