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 …

Land-use intensification reshapes microbial phosphorus cycling, organic matter composition, and phosphorus fractions in Amazonian soils

Guilherme Lucio Martins, Gabriel Gustavo Tavares Nunes Monteiro, Markus Lange, Anderson Santos de Freitas et autres

Soil phosphorus (P) is a limiting factor for vegetation growth in the Amazon rainforest, where plants depend on microorganisms for organic matter cycling and nutrient uptake. While forest-to-agriculture conversion fundamentally reshapes plant-microbe-soil interactions and P cycling, these dynamics are further modulated by …

Land Use and Its Impact on Phosphorus Adsorption Capacity in a Tropical Dryland Agricultural Frontier: Insights and Predictive Modeling

José Wilker Germano de Souza, João Henrique Silva da Luz, Dayane Mércia Ribeiro Silva, Ricardo Barros Silva et autres

Land use significantly impacts the physical-chemical properties of soil, particularly in tropical regions where the maximum phosphorus adsorption capacity (MPAC) plays a crucial role in agricultural sustainability. This study evaluates the influence of land uses (cropland, grassland, and forest) on MPAC in …

Humic and fulvic acid derived from slaughterhouse waste compost as biostimulants in Marandu grass

João Henrique Silva da Luz, Evandro Alves Ribeiro, Bruno Henrique di Napoli Nunes, Hanrara Pires de Oliveira et autres

ABSTRACT Humic and fulvic acids promote the growth and development of different cash crops through biostimulation. However, when extracted from alternative sources, their effects on forage crops are unknown. Thus, the present study aimed to assess the effect of foliar spraying humic …

Application of Plant Growth Regulators Mitigates Water Stress in Basil

Dayane Mércia Ribeiro Silva, Isabelly Cristina da Silva Marques, Beatriz Lívero Carvalho, Eduardo Santana Aires et autres

Abiotic stresses, such as water limitation, are significant limiting factors in basil production. One alternative to mitigate the harmful effects of this stress on plants is using plant growth regulators. This study’s objective is to evaluate different doses of plant regulators in …

Short-Term Agronomic and Economic Responses to the Adoption of Cover Crops for Corn Rotation in the Brazilian Semiarid Region

João Henrique Silva da Luz, Matheus Batista da Silva, Luana do Nascimento Silva Barbosa, José Wilker Germano de Souza et autres

Cover crops (CCs) have demonstrated their significance in enhancing the agronomic and economic performance of corn in succession. In this paper, we assess the agronomic responses and short-term economic returns of adopting cover crops (CCs) for corn cultivation in the sandy soils …
