Impacts of Biostimulants on Nitrous Oxide Emissions and the Soil Microbiome

Journal of Plant Nutrition and Soil Science, EarlyView.
Soil incubation experiment examining the influence of biostimulants on greenhouse gas emissions and the soil microbiome in fertilized soils. ABSTRACT Background Overapplication of nitrogenous fertilizer and enhanced microbial activity in agricultural soils are drivers of increasing greenhouse gas emissions.

Moderate Fire Temperatures Affect the Structure of Clayey Oxisol Aggregates

Land Degradation &Development, EarlyView.
ABSTRACT Wildfires have become increasingly frequent and intense worldwide, raising concerns about their impacts on soil systems. However, the thermal responses of clay‐rich Oxisols, dominated by Fe and Al oxides, remain poorly understood. In this study, samples from the 0 to 5 cm layer of six Oxisols were subjected to controlled heating at ...

Phosphorus adsorption and release dynamics in calcareous soil as affected by humic and fulvic acids

Journal of Degraded and Mining Lands Management
Humic and fulvic acids play a crucial role in enhancing phosphorus retention in calcareous soils. These organic acids increase phosphorus fixation on soil surfaces, thereby strengthening its binding and modifying its availability in the soil solution ...

Biomass composite with exogenous organic acid addition supports the growth of sweet sorghum (Sorghum bicolor ‘Dochna’) by reducing salinity and increasing nutrient levels in coastal saline–alkaline soil

Frontiers in Plant Science, 2023
IntroductionIn coastal saline lands, organic matter is scarce and saline stress is high. Exploring the promotion effect of intervention with organic acid from biological materials on soil improvement and thus forage output and determining the related ...

Hurdles to overcome to achieve biostimulant‐driven, low chemical input crop production

PLANTS, PEOPLE, PLANET, EarlyView.
Crop production requires considerable chemical inputs that result in significant greenhouse gas emissions and other environmental costs. Biostimulants are natural agents, such as microorganisms or seaweed, applied to plants and soil to stimulate plant growth and reduce chemical inputs. Biostimulant use is rapidly increasing globally, but hurdles remain,

Effect of potassium fulvate on continuous tobacco cropping soils and crop growth

Frontiers in Plant Science
Long-term continuous cropping of tobacco causes dysbiosis of soil microbial communities, the imbalance of soil nutrients, and the increase of pathogenic bacteria, which will slow the growth and development of tobacco plants, reduce the production quality,

Fulvic Acids and Viral Infections

The Open Conference Proceedings Journal, 2012
Fulvic acids are active principles in humic substances allowing big absorption of mineral ions from soil through vegetables. They are formed by large organic molecules having several reactive sites. Tested in mice and rats with radio- active labeled ions ( 45 Ca 2+ , 32 PO4 3- , 59 Fe 3+ and 131 I - ) in drinking water, it has been found that for even ...

Plant biostimulants and their potential role in achieving the United Nations sustainable development goals

PLANTS, PEOPLE, PLANET, EarlyView.
Plant biostimulants are substances that are obtained from a variety of sources and are applied in minute quantities to enhance plant growth and vigor. In this review we detail how the use of plant biostimulants may contribute to efforts to achieving a number of the UN Sustainable Development Goals.
