ABSTRACT:
Importance of phosphorus in plants
Nutrient availability in the soil does not always meet plant requirements, which compromises agricultural productivity. Harvesting removes nutrients, and when combined with inadequate replenishment, natural depletion, and specific soil characteristics, this leads to nutritional deficiencies. Consequently, reliance on mineral fertilizers increases (ARNON; STOUT, 1939; WINIWARTER, 2014; PRAKASH et al., 2015).
Phosphorus (P) is a macronutrient that frequently limits plant growth (KALAYU, 2019). In Brazilian soils, it exhibits low availability and high fixation rates in low-pH environments. Within the soil solution, P can be taken up by microbial biomass, assimilated by plants, fixed in the soil matrix, or precipitated in the presence of iron, aluminum, and calcium, depending on the pH (MOREIRA; SIQUEIRA, 2006; NOVAIS; SMYTH, 1999).
