This review covers the literature data on plant growth-promoting bacteria in soil, which can fix atmospheric nitrogen, solubilize phosphates, produce and secrete siderophores, may exhibit several different behaviors simultaneously. We discuss perspectives for creating bacterial consortia introducing them into soil to increase crop productivity agrosystems. The application of rhizosphere bacteria-which are capable fixing solubilizing organic inorganic secreting as well their consortia-has been demonstrated meet objectives sustainable agriculture, such increasing fertility yields. combining with mineral fertilizers is a crucial trend that allows reduction fertilizer use beneficial production.

The soil microbiome plays an important role in maintaining health, plant productivity, and ecosystem services. Current molecular-based studies have shed light on the fact that has been quantitatively underestimated. In addition to metagenomic studies, metaproteomics metatranscriptomic target functional part of are becoming more common. These for a better understanding deciphering plant-microbe interactions. Free-living beneficial bacteria promote growth by colonizing roots called growth-promoting rhizobacteria (PGPRs). They exert their effects different ways, either facilitating uptake nutrients synthesizing particular compounds plants or preventing protecting from diseases. A interactions both natural agroecosystems will offer us biotechnological tool managing fertility obtaining high-yield food production system.

Intercropping systems can flexibly use resources such as sunlight, heat, water, and nutrients in time space, improve crop yield land utilization rates, effectively reduce continuous cropping obstacles the occurrence of diseases insect pests, control growth weeds. Thus, intercropping is a safe efficient ecological planting mode. The legume–cereal system most common combination. Legume crops fix nitrogen from atmosphere through their symbiotic fixation abilities, fixed be transferred to utilized by cereal various ways. efficiency legume was improved reducing inhibition soil on nitrogenase activity competitive absorption nitrogen. However, effects transformation distribution microbial community structure characteristics transfer need further explored. In this review, (ⅰ) we present system; (ⅱ) describe systems; (ⅲ) discuss advantages using modern biological molecular techniques study microorganisms. We conclude that increase diversity microorganisms, interaction between different plants has an important impact composition bacterial fungal communities. extensive application research great contribution sustainable agriculture are particularly emphasized review.

Abstract Due to their unique properties, nanomaterials behave peculiarly in biosystems. Regarding plants, the interactions of can be interpreted on a spatial scale: from local cells systemic effects whole plants and ecosystems. Interpreted time scale, may immediate or subsequent. At cellular level, composition structure cell wall membranes are modified by nanomaterials, promoting internalization. The germination seedling physiology primary secondary metabolism shoot realized at organ organism levels. Nanomaterials interact with beneficial ecological partners plants. plant growth-promoting rhizobacteria legume–rhizobia symbiosis stimulating inhibitory, depending concentration type nanomaterial. exert negative effect arbuscular mycorrhiza, vice versa. Pollinators exposed which affect reproduction. substances released roots influence availability rhizosphere, components trigger internalization, translocation, transformation nanomaterials. Understanding multilevel bidirectional relationship between is great relevance.

Abstract A regional geopolitical conflict and sudden massive supply disruptions have revealed vulnerabilities in our global fuel–fertilizer–food nexus. As nitrogen (N) fertilizer price spikes threaten food security, differentiated responses are required to maintain staple cereal yields across over- underfertilized agricultural systems. Through integrated management of organic inorganic N sources high- low-input production systems, we estimate potential total N-fertilizer savings 11% India, 49% Ethiopia 44% Malawi. Shifting more cost-effective, high-N (such as urea), combined with compost integration legumes, can optimize N-deficient Better targeted efficient use will benefit systems surplus N. Geospatially fertilization strategies should prioritize low-yield, locations balanced N, P, K micronutrients high-yield Nationally, governments invest extension realign subsidies enable incentivize improved at the farm level.

Abstract In the Indo-Gangetic Plains (IGP), rice–wheat cropping system (RWCS) predominates, producing large quantity of crop residue and its management is major concern. Farmers usually burn to clear field for succeding crop, burning damages soil microbes, resulted in loss organic matter. Hence, current study was conducted assess impact different Happy seeder based options on changes microbial dynamics, enzyme activities matter content also know that alternative method attaining sustainable wheat productivity sandy loam soils Haryana, India. Results revealed Zero tillage (ZTW) with partial full retention treatments sown (after using chopper spreader), ZTW anchored stubbles significantly enhanced count by 47.9–60.4%, diazotropic 59.0–73.1% actinomycetes 47.3–55.2%, grain yield 9.8–11.3% biomass 7.4–9.6% over conventional tilled (CT) removal plots. surface rice increased carbon 0.36–0.42% moisture 13.4–23.6% CTW without load.

Nitrogen compounds like ammonia and nitrite can antagonistically affect the environment human health in many ways. The high rise demand for food has led to excessive use of fertilisers eventually causing increased losses reactive nitrogen environment. Ammonia be introduced into through agricultural runoff, wastewater discharges other anthropogenic activities. over-accumulation different forms (ammonia nitrite) ecosystem noxious life including humans aquatic life. High concentrations both nitrogenous nutrient pollution, decreased oxygen levels water bodies ultimately resulting dead zones eutrophication. In elevated cause methemoglobinemia. Remediation these contaminants become a crucial environmental concern recent past. To prevent pollution reduce their harmful effects several mechanisms physical chemical treatments have been it is also required fix remaining pollutants by biological agents. Current review deals with mechanism, organisms, enzymes involved transformation fixation various (fixation using chemicals, modified biochar, solidification, phytostabilisation, nano material-related compounds, etc.)
