The increasing use and the continuous development of pesticides are required to maintain sufficient global food production. The pesticide residues and their biotic and abiotic breakdown products may be harmful to the environment and may leach into waterways, thus it is crucial that the interactions of pesticides with microorganisms are deeply understood at all levels. Pesticides reach the soil via direct and indirect routes. The fate of the pesticides in the soil is affected by chemical, physical and microbiological factors. Microbial degradation of pesticides in soil is possible owing to the diverse metabolic capabilities of the microorganisms present, thus indigenous microbes act as biocatalysts for the remediation of the pesticides from the environment. The research topic will cover novel insights into microbial pesticide degradation with specific attention to the microbe-pesticide interactions in soil. To date researchers have focused on the degradation of pesticides using indigenous microbes with different degradation rate. There is scant information about the degradation intermediates, metabolic pathways, enzymes and complete set of factors involved into the microbes inhabiting into the pesticides contaminated soil. Therefore this Research Topic aims to contribute to the understanding of the role of microbes in pesticide degradation in soil. Since pesticide exposure may result in stress responses in the microbial population of the soil, there is also a need to know about the impact of pesticides on the microbial cell structure, membrane transporters, cellular content, metabolic pathways and gene expression. We are interested in reports of novel metabolic pathways, expression of the key genes in response to pesticide exposure and the changes in microbial physiology caused by pesticide exposure. The removal of the pesticides from the soil requires smart microbial methods that can reduce the pesticides concentration in a short time. The development of the smart bioremediation methods includes the direct application of the potential screened microbial strains and their enzymes. The immobilized microbial strains and their enzymes can be used for the rapid removal of the toxic pesticides from the soil environment. In addition, engineering of the microbial consortia can be developed as the potential smart bioremediation tool. Papers on single isolates or microbial communities are welcome as are reports of novel genes, enzymes or metabolites that might be used as markers of soil contamination. We would especially welcome manuscripts describing the application and development of smart soil bioremediation approaches that could be beneficial for the treatment of large scale contaminated agricultural and industrial soils. The research topic is of immediate interest to scientists and policy-makers and Frontiers in Microbiology is an ideal forum for a collection of novel, high-impact reports. The following themes are welcomes but not limited to: • Novel advancements into the microbe-pesticide interactions to clean the pesticide contaminated soil • High throughput screening of the potential bacterial, fungi and algae strains for the removal of pesticides from the contaminated soil • Smart soil bioremediation using indigenous microbial cultures and their purified enzymes • Microbial enzymes a smart tool for bioremediation of the soil • Engineering of the microbial consortia for the complete pesticides removal and resource recovery

Of all the food produced in the world one third is lost to insect pests, weeds and diseases, and the total world population is estimated as growing from 4000 million in 1975 to about 6000 million by the year 2000. To satisfy these needs, the world's farmers must meet the extra requirement every year. The easiest way in which farmers can increase the amount of food they produce is to prevent the loss due to pests. The biological control measures which were once thought to be the safest methods of pest control have, as we now know, not proved successful on a commercial scale. In such a dismal situation the only solution is to use pesticides to save the losses from pests and to increase the crop yield. Apart from agriculture, pesticides have also contributed much to human com fort by controlling the vectors of typhoid, malaria, sleeping sickness, filariasis, dengue hemorrhage fever, plague etc. On the other hand, the indiscriminate use of insecticides and their harmful effects on nontarget organisms has attracted much attention from people in all walks of life, for example, scientists, administrators, the press and the public. The harmful effects of insecticides on higher organisms such as birds, fish and mammals are easy to observe and have received much attention. However, the interactions of insecticides with microorganisms such as bacteria, fungi, algae and protozoa have gone unnoticed until recently.

The interactions between the plant, soil and microbes are complex in nature. Events may be antagonistic, mutualistic or synergistic, depending upon the types of microorganisms and their association with the plant and soil in question. Multi-trophic tactics can therefore be employed to nourish plants in various habitats and growth conditions. Understanding the mechanisms of these interactions is thus highly desired in order to utilize the knowledge in an ecofriendly and sustainable way. This holistic approach to crop improvement may not only resolve the upcoming food security issues, but also make the environment greener by reducing the chemical inputs. Plant, soil and microbe, Volume 1: Implications in Crop Science, along with the forthcoming Volume 2: Mechanisms and Molecular Interactions, provide detailed accounts of the exquisite and delicate balance between the three critical components of agronomy. Specifically, these two titles focus on the basis of nutrient exchange between the microorganisms and the host plants, the mechanism of disease protection and the recent molecular details emerged from studying this multi-tropic interaction. Together they aim to provide a solid foundation for the students, teachers, and researchers interested in soil microbiology, plant pathology, ecology and agronomy.

The dependence of present farming on artificial input of “chemical fertilizers” has caused numerous ecological tribulations associated with global warming and soil contamination. Moreover, there is an essential requirement for realistic agricultural practices on a comprehensive level. Accordingly, biofertilizers including microbes have been recommended as feasible environmentally sound solutions for agricultural practices which not only are natural, and cost-effective but also preserve soil environs and important biota of agricultural land. In addition, it enhances the nutrient quantity of soils organically. Microbial biofertilizers promote plant growth by escalating proficient absorption of nutrients for the plants and by providing an excellent disease-fighting mechanism.Agriculture, the backbone of human sustenance, has been put under tremendous pressure by the ever-increasing human population. Although various modern agro-techniques boosted agricultural production, the excessive use of synthetic fertilizers, pesticides and herbicides have proven extremely detrimental to agriculture as well as to the environment in which it is carried out. Besides this some faulty agricultural practices like monoculture and defective irrigation, further complicate the scenario by eliminating biodiversity, increasing the efflux of nutrients into the water bodies, the formation of algal blooms, eutrophication, damaging the water quality and lowering fish stocks. Biofertilizers are the organic compounds applied to crops for their sustainable growth and the sustainability of the environment as the microbiota associated with biofertilizers interact with the soil, roots and seeds to enhance soil fertility. Application of biofertilizers results in the increased mineral and water uptake, root development, vegetative growth and nitrogen fixation besides liberating growth-promoting substances and minerals that help the maintenance of soil fertility. They further act as antagonists and play a pivotal role in neutralising soil-borne plant pathogens and thus, help in the bio-control of diseases. Application of biofertilizers instead of synthetic fertilizers could be a promising technique to raise agricultural productivity without degrading environmental quality. The present book focuses on the latest research approaches and updates from the microbiota and their applications in the agriculture industry. We believe this book addresses various challenges and shed lights on the possible future of the sustainable agricultural system.
