Cover cropping is a promising sustainable agricultural method with the potential to enhance soil health and mitigate consequences of degradation. Because cover can form an agroecosystem distinct from that bare fallow, microbiome hypothesized respond altered environmental circumstances. Despite growing number primary literature sources investigating relationship between microbiome, there has not been quantitative research synthesis sufficiently comprehensive specific this relationship. We conducted meta-analysis by compiling results 60 relevant studies reporting effects on microbial properties estimate global effect sizes explore current landscape topic. Overall, significantly increased parameters abundance, activity, diversity 27%, 22%, 2.5% respectively, compared those fallow. Moreover, varied covariates like crop termination or tillage methods. Notably, were less pronounced under conditions continental climate, chemical termination, conservation tillage. This showed become more robust when properly managed other practices.

Role of Arbuscular Mycorrhizal Fungi in Regulating Growth, Enhancing Productivity, and Potentially Influencing Ecosystems under Abiotic and Biotic Stresses

Plants, Journal Year: 2023, Volume and Issue: 12(17), P. 3102 - 3102

Published: Aug. 29, 2023

Arbuscular mycorrhizal fungi (AMF) form symbiotic relationships with the roots of nearly all land-dwelling plants, increasing growth and productivity, especially during abiotic stress. AMF improves plant development by improving nutrient acquisition, such as phosphorus, water, mineral uptake. tolerance resilience to stressors drought, salt, heavy metal toxicity. These benefits come from arbuscular interface, which lets fungal partners exchange nutrients, signalling molecules, protective chemical compounds. Plants' antioxidant defence systems, osmotic adjustment, hormone regulation are also affected infestation. responses promote performance, photosynthetic efficiency, biomass production in stress conditions.

Phosphate‐solubilising microorganisms for improved crop productivity: a critical assessment

New Phytologist, Journal Year: 2020, Volume and Issue: 229(3), P. 1268 - 1277

Published: Sept. 16, 2020

Phosphate-solubilising microorganisms (PSM) are often reported to have positive effects on crop productivity through enhanced phosphorus (P) nutrition. Our aim was evaluate the validity of this concept. Most studies that report 'positive effects' PSM plant growth been conducted under controlled conditions, whereas field experiments more frequently fail demonstrate a response. Many indicated mechanisms seen in vitro do not translate into improved P nutrition complex soil-plant systems. Furthermore, associated rigorously assessed. We suggest mobilise sufficient change crops' nutritional environment conditions. The current concept, which solubilise 'for plant' should thus be revised. Although capacity meet their own needs, it is turnover microbial biomass subsequently provides plants over longer time. Therefore, existing concept function unlikely deliver reliable strategy for increasing A further mechanistic understanding needed determine how mobilisation by as component whole soil community can manipulated become effective

Phosphates are known to be essential for plant growth and development, with phosphorus compounds being involved in various physiological biochemical reactions. as one of the most important factors limiting crop yields. The problem deficiency soil has traditionally been solved by applying phosphate fertilizers. However, chemical fertilizers considered ineffective compared organic manure compost. Therefore, increasing bioavailability phosphates plants is primary goals sustainable agriculture. Phosphate-solubilizing microorganisms can make soil-insoluble bioavailable through solubilization mineralization. These currently focus interest due their advantages, such environmental friendliness, low cost, high biological efficiency. In this regard, holds strong potential research, inoculation soils or crops phosphate-solubilizing bacteria a promising strategy improve uptake. review, we analyze all species described literature date.
