Biological nitrogen fixation (BNF) refers to a microbial mediated process based upon an enzymatic “Nitrogenase” conversion of atmospheric (N 2 ) into ammonium readily absorbable by roots. N -fixing microorganisms collectively termed as “diazotrophs” are able fix biologically in association with plant Specifically, the symbiotic rhizobacteria induce structural and physiological modifications bacterial cells roots specialized structures called nodules. Other bacteria free-living fixers that highly diverse globally widespread cropland. They represent key natural source (N) agricultural ecosystems lacking (SNF). In this review, importance Azotobacter species was highlighted both important potential biofertilizer proven efficacy for nutrition biological soil fertility. addition, we described beneficial promoting traits (e.g., nutrient use efficiency, protection against phytopathogens, phytohormone biosynthesis, etc.). We shed light also on agronomic features likely effective component integrated strategy, which contributes positively sustainable production. pointed out based-biofertilizers, possess unique characteristics such cyst formation conferring resistance environmental stresses.

Uptake, Translocation, and Consequences of Nanomaterials on Plant Growth and Stress Adaptation

Journal of Nanomaterials, Год журнала: 2021, Номер 2021, С. 1 - 17

Nanotechnology has shown promising potential tools and strategies at the nanometer scale to improve food production meet future demands of agricultural security. However, considering nanotechnology’s benefits date, their applicability not yet reached up field conditions. Increasing concerns regarding absorption, translocation, bioavailability, toxicity nanoparticles, impropriety regulatory framework restrict complete acceptance inclination sector implement nanotechnologies. The biological function nanoparticles depends on physicochemical properties, method application, concentration. effects various types (NPs) plants were determined increase seed germination biomass or grain yield. NPs also increased plant’s resistance biotic abiotic stresses. functions depend events that occur molecular level. little progress been made level influenced by which is an important step in evaluating mechanisms plants’ effects. Therefore, it understand underlying mechanism response towards gene expression changes through approaches. associations nanomaterials with plant cells, process internalization, distribution biomolecules using as a carrier are studied but well understood. transmission biomolecules, such nucleic acids, major obstacle due cell walls, limiting application crop enhancement mediated genetic engineering. Recently, use different for acid delivery cells published. Here, we aim update researchers absorption translocation elaborate importance agriculture stress tolerance.

Phosphate bacterial solubilization: A key rhizosphere driving force enabling higher P use efficiency and crop productivity

Journal of Advanced Research, Год журнала: 2021, Номер 38, С. 13 - 28

Опубликована: Авг. 23, 2021

Increasing crop production to feed a growing population has driven the use of mineral fertilizers ensure nutrients availability and fertility agricultural soils. After nitrogen, phosphorus (P) is second most important nutrient for plant growth productivity. However, P in soils often limited because strongly binds soil particles divalent cations forming insoluble P-complexes. Therefore, there constant need sustainably improve availability. This may include, among other strategies, application microbial resources specialized cycling, such as phosphate solubilizing bacteria (PSB). P-mediating bacterial component can biological production, should be integrated well-established formulations enhance efficiency P. importance fertilization, including both organic rock (RP) aiming its agronomic within an nutrition system where profitability PSB synergistically occur. The purpose this review discuss critically contribution concert with fertilizers, specific focus on RP. We also highlight bioformulations being sustainable approach fertilizer production. first recognize sustain which requires rational screening evaluation enabling accurate assessment effects alone intertwined interaction roots. Furthermore, we propose new research ideas about development based particular strains exhibiting synergetic

Revealing soil legacy phosphorus to promote sustainable agriculture in Brazil

Scientific Reports, Год журнала: 2020, Номер 10(1)

Опубликована: Сен. 28, 2020

Abstract Exploiting native soil phosphorus (P) and the large reservoirs of residual P accumulated over decades cultivation, namely “legacy P”, has great potential to overcome high demand fertilisers in Brazilian cropping systems. Long-term field experiments have shown that a proportion (> 70%) surplus added via remains soil, mainly forms not readily available crops. An important issue is if amount legacy mobilized from sufficient for crop nutritional how long this stored can be effectively ‘mined’ by crops profitable way. Here we mapped spatial–temporal distribution past 50 years, discussed possible agricultural practices could increase usage plants Brazil. Mineral fertiliser manure applications resulted ~ 33.4 Tg soils 1967 2016, with current annual rate 1.6 Tg. Following same rate, may reach up 106.5 2050. Agricultural management enhance includes increasing pH liming, rotation, double-cropping, inter-season cover crops, no-tillage system use modern fertilisers, addition more efficient varieties inoculation solubilising microorganisms. The adoption these efficiency P, substantially reducing new input thus save 31.8 (US$ 20.8 billion) coming decades. Therefore, exploring imperative reduce mineral while promoting long-term sustainability
