Tomato Yield and Fruit Size Did Not Respond to P Fertilization of a Sandy Soil Testing Very High in Mehlich-1 P [PDF]

HortScience, 1999
Tomato (Lycopersicon esculentum Mill.) was grown in southeastern Florida on sandy soils that tested very high in Mehlich-1 P to evaluate the yield response to P fertilization. One location was used in 1995–96, another in 1996–97. Prefertilization soil samples contained 290 (location 1) and 63

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

Land Degradation &Development, EarlyView.
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, EarlyView.
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 ...

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 ...

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 ...

Boron extraction and vertical mobility in Paraná State oxisol, Brazil Extração e mobilidade vertical de boro em latossolo vermelho eutroférrico no Estado do Paraná

Revista Brasileira de Ciência do Solo, 2009
The deficiency or excess of micronutrients has been determined by analyses of soil and plant tissue. In Brazil, the lack of studies that would define and standardize extraction and determination methods, as well as lack of correlation and calibration ...

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.

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,
