Soil Texture Modulates Phosphorus Dynamics, Enzyme Activity and root Responses to Phosphorus, zinc and Biofertilizer Inputs in Citrus Rhizosphere

Rafael Miranda de Lima Carvalho, Raja Yamma Rodrigues Souza, Lusiane de Sousa Ferreira, Gabriel Antonio Bortoloti et autres

Purpose: Phosphorus (P) fertilization is essential for citrus establishment in tropical soils, where soil texture strongly influences P availability and rhizosphere nutrient dynamics. This study evaluated the effects of localized P application, alone or combined with zinc (Zn) or a bioinput, on …

Potential of Composted Macrophytes as a Sustainable Organic Fertilizer: Environmental and Agronomic Insights

Paulo Sergio Costa Trindade, Andre Luiz de Freitas Espinoza, João Henrique Silva da Luz, Ingrid Martins Stelutti et autres

Abstract This study evaluated the agronomic potential and environmental impact of a macrophyte-based fertilizer (OMF) in maize cultivation. OMF was previously characterized in accordance with regulatory standards and applied to sandy loam and clayey soils at six rates (0, 2, 4, 6, …

vegetation and tight C-N cycling. Using synchrotron-based micro-FTIR imaging, we observed that PG promoted greater spatial clustering of SOC functional groups and stronger organo-mineral associations with clay minerals, suggesting enhanced SOC stabilization. These findings suggest that stabilization occurred primarily through enhanced physical …

Phosphorus availability and legacy in highly weathered soils: Unveiling the interplay with soil aggregation across diverse agricultural land uses as integrated systems

Maurício Cunha Almeida Leite, Júlio César Salton, Alberto Carlos de Campos Bernardi, Michely Tomazi et autres

Phosphorus (P) availability is a critical concern in tropical agriculture, particularly in highly weathered soils. Because soil functions are structured hierarchically and organized through aggregate-scale process, land use is closely associated with P availability and legacy through alterations in soil structure. However, …

Cover crops modulate soil phosphorus dynamics under P fertilizer sources in dryland maize production on tropical soil

Luana do Nascimento Silva Barbosa, João Henrique Silva da Luz, Rosemery Alesandra Firmino dos Santos, José Wilker Germano de Souza et autres

Phosphorus (P) is essential for plant growth but is frequently limiting in tropical agroecosystems due to strong sorption and low availability. The adoption of cover crops (CCs) with high P uptake efficiency can enhance P cycling for cash crops, reducing fertilizer use …

Diverse production systems affect soil phosphorus forms and crop productivity in tropical soil

Jossanya Benilsy dos Santos Silva Castro, Jorge Delfim, Laércio Santos Silva, Gabriela Castro Pires et autres

Diversified agricultural systems, associated with greater species diversity (SD), can alter the dynamics of phosphorus (P) in the soil and consequently increase crop productivity. This study evaluated the P forms and yields of soybean and cotton in a sandy loam Ultisol under …

How the Rhizosphere Chemistry Explains the Effectiveness of Radish (Raphanus sativus L.) in Reclaiming Legacy Phosphorus Compared to Maize (Zea mays L.)

Yahaya Mohammad Yusuf, Gabriel Sgarbiero Montanha, Kaoutar Benghzial, Paulo Sérgio Pavinato et autres

Around 50% of phosphorus (P) applied to tropical soils is not used by plants and becomes part of the legacy P. However, certain cover crops can access this P pool. But how do they extract this P, which form do they extract …

Multi-site evaluation of phosphorus fertilization with bio-inputs in sugarcane: Yield and soil P fractions

Gabriel Pinheiro Silva, Sarah Mello Leite Moretti, Ingrid Martins Stelutti, Paulo Sérgio Pavinato et autres

Background Phosphorus (P) deficiencies in highly weathered tropical soils limits sugarcane productivity, and the agronomic value of bio-inputs and phosphorus reapplication remain uncertain. We evaluated whether integrating bio-inputs with phosphorus fertilization increases yield and modifies soil phosphorus pools across contrasting environments. Methods …

Agronomic performance of maize and cover crops using composted sewage sludge to supply phosphorus

Nathércia Castro Elias, João Henrique Silva da Luz, Raimunda Eliane Nascimento do Nascimento, Philippe Solano Toledo Silva et autres

Abstract The application of composted sewage sludge (CSS) in crop production offers a sustainable solution for nutrient recycling and reducing reliance on mineral fertilizers. This study evaluated the residual effects of CSS on phosphorus (P) bioavailability and agronomic performance of maize and …
