چکیده
In tropical no-till systems, applying lime (L) and phosphogypsum (PG) on the soil surface may be a potential strategy for reducing acidification improving soybean root growth, thereby enhancing plant nutrition physiological responses and, in turn, crop resistance to dry spells. This study evaluated impact of long-term (17 years) amendment fertility development, nutrition, gas exchange, carbon antioxidant enzyme activity, grain yield region subject The treatments consisted following amendments: control (no amendment); L alone; PG + (LPG). Liming, especially when combined with PG, improved fertility, as evidenced by increases pH P, Ca2+, Mg2+ levels throughout profile, but reduced Al3+ micronutrients (Fe, Mn, Cu, Zn). improvements were associated increased development profile. Long-term application LPG negative impacts spells pigment concentrations, Rubisco sucrose synthase activities metabolism, yield. Our results reveal that is an important approach increasing vertical movement cationic bases roots systems improve nutrition. enhanced both metabolism plants, resulting higher yield, despite predisposition this
