Low soil fertility in savanna soils has been linked to low crop yields, with nitrogen being the most limiting factor yield. Soil used this pot experiment was obtained from Motshephiri village total N, NO3− and high NH4+. A conducted a greenhouse laid Randomized Complete Block Design four treatments (1) control, (2) Bradyrhizobium japonicum inoculant, (3) superphosphate (4) inoculant + superphos...

No-till farming and manure application are means of storing carbon in soil increasing quality. However, the organic fertilization no-till soils may sustain subtropical agroecosystems for only a limited period until quality declines. The C, N, P, other nutrient cycles perturbed due to imbalance manures their on surface, which poses risk dispersion into environment. Long-term N-based also impacts...

Phosphorus (P) is a non-renewable resource whose future scarcity will constrain agricultural sustainability. Thus, to ensure this sustainability, circular economy approach involving the use of recycled P sources needed. The objective study was assess fertilizer effect two products that can be obtained from water purification: vivianites and struvites. Five (one synthetic, one industrial process...
