LOSS OF EXTRACTION CAPACITY OF MEHLICH-1 AND MONOCALCIUM PHOSPHATE AS A VARIABLE OF REMAINING P AND ITS RELATIONSHIP TO CRITICAL LEVELS OF SOIL PHOSPHORUS AND SULFUR [PDF]

Revista Brasileira de Ciência do Solo, 2015
The Mehlich-1 (M-1) extractant and Monocalcium Phosphate in acetic acid (MCPa) have mechanisms for extraction of available P and S in acidity and in ligand exchange, whether of the sulfate of the extractant by the phosphate of the soil, or of the phosphate of the extractant by the sulfate of the soil. In clayey soils, with greater P adsorption capacity,

Effect of Phosphate Fertilization and Cutting Date Improves Nutritional Status and Productive Parameters of a Tropical Forage Legume

Legume Science, Volume 8, Issue 3, September 2026.
ABSTRACT The use of chemical fertilizers is economically and environmentally costly to produce and apply. Therefore, optimized fertilizer use is critical to increase or maintain crop yields. We evaluated the productive and nutritional characteristics of the Stylosanthes cv “Campo Grande” submitted to different cutting date and phosphate fertilization ...

Bioavailable phosphorus across Florida’s diverse soil orders: implications for crop productivity and environmental protection

Frontiers in Environmental Science
Effective phosphorus (P) management is critical for sustainable agricultural production in Florida. The state’s diverse acid-mineral soils, including Alfisols, Entisols, Spodosols, and Ultisols, exhibit distinct physiochemical properties that profoundly ...

Implementing potential climate‐smart practices through diverse partnerships

PLANTS, PEOPLE, PLANET, Volume 8, Issue 5, Page 1584-1598, September 2026.
Climate change is one of the greatest threats to society, negatively impacting agriculture and crop yields. Globally, agriculture is also one of the largest greenhouse gas (GHG) emitting sectors. Climate‐smart practices that are developed through diverse partnerships with scientists and practitioners are needed to decrease GHG emissions. We implemented

Crop genotypic richness enhances biomass production and phosphorus acquisition in maize‐mycorrhiza symbiosis

PLANTS, PEOPLE, PLANET, Volume 8, Issue 5, Page 1702-1714, September 2026.
Our study tests how soil and plant biodiversity can enhance sustainability of crop production in Kenya. We tested whether mixtures of maize varieties performed better than monocultures and tested their response to arbuscular mycorrhizal fungi. Mycorrhizal responsiveness differed significantly by maize variety, and genetic mixtures outperformed ...

Establishment Limitations of Sensitive Target Species Potentilla alba L. in Grasslands Restored on Arable Land

Land Degradation &Development, Volume 37, Issue 14, Page 10053-10062, 30 August 2026.
ABSTRACT Species in grasslands restored from former arable land have multiple obstacles when establishing. Understanding whether these limitations stem from soil chemical or microbial differences could help to create suitable environments for specific target and other species with similar requirements.

Assessing Soil and Management Quality Indexes in A Rural Watershed Under Long‐Term No‐Tillage in Southern Brazil

Land Degradation &Development, Volume 37, Issue 14, Page 10217-10231, 30 August 2026.
ABSTRACT Soil quality assessment is essential to detect management failures and prevent land degradation in agricultural systems. No‐tillage system (NTS) is a conservation management widely adopted in Brazil, but its effectiveness is compromised when adherence to the core principles of crop rotation and ground cover is not complete, and basic ...
