Correlation and calibration of Mehlich‐3 sulfur for Kentucky bluegrass

Crop Science
Abstract Sulfur (S) is a crucial macronutrient for turfgrass growth, and declining atmospheric deposition has increased the risk of S deficiency. Reliable Mehlich‐3 soil test interpretations for S are lacking for turfgrass.

Implementing potential climate‐smart practices through diverse partnerships

PLANTS, PEOPLE, PLANET, EarlyView.
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

Extraction methods and availability of micronutrients for wheat under a no-till system with a surface application of lime Métodos de extração e disponibilidade de micronutrientes para o trigo cultivado em plantio direto com calagem na superfície

Scientia Agricola, 2010
Micronutrient availability can be affected by the increase of the soil pH due to surface liming. A field trial was carried out on a loamy, kaolinitic, thermic Typic Hapludox at Ponta Grossa, Paraná State, Brazil.

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

PLANTS, PEOPLE, PLANET, EarlyView.
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 ...

Calibração de métodos de determinação de fósforo em solos cultivados sob sistema plantio direto Calibration of phosphorus extraction methods in soils cultivated under no-tillage

Revista Brasileira de Ciência do Solo, 2008
A mudança no sistema de preparo do solo e cultivo das plantas, do sistema convencional para o plantio direto, na profundidade de amostragem e o aumento de rendimento das culturas, ao longo do tempo podem alterar os teores críticos de P, as faixas de ...

Soil pH thresholds mediate soil biodiversity by regulating interspecific associations in alpine wetlands of the Qinghai–Tibetan Plateau

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Soil pH is recognized as a major determinant of soil biodiversity. However, the extent to which soil pH regulates soil biodiversity by influencing the biotic associations among species is unclear.

Photosynthetic Traits Underlying Yield Differences in Irrigated and Rainfed Soybean Systems in the Mississippi Delta

Plant-Environment Interactions, Volume 7, Issue 4, August 2026.
ABSTRACT Understanding photosynthetic processes under field conditions is critical for identifying physiological determinants of seed yield (SY) in soybean. This study evaluated leaf gas exchange and chlorophyll fluorescence traits in seven soybean cultivars grown under irrigated (IR) and rainfed (RF) environments in the Mississippi Delta.

Extração de cobre e de zinco por soluções multielementares em solos do sul do Brasil Copper and zinc extracted by multielement solution for Southern Brazilian soils

Ciência Rural, 2010
As quantidades extraídas de cobre (Cu) e de zinco (Zn) pelas soluções de HCl 0,1mol L-1 (HCl) foram comparadas com as extraídas pelas soluções de Mehlich-1 (M1) e de Mehlich-3 (M3).
