    Advance technology for biostimulants in agriculture
    (Elsevier, 2022) Bahuguna, Ayush; Sharma, Sachin; Rai, Ashish; Bhardwaj, Reshu; Sahoo, Sanjib Kumar; Pandey, Astha; Yadav, Bharti
    Biostimulants are substances, different from fertilizers, which stimulate plant growth when applied in minute quantities. They are increasingly used in worldwide agricultural production and can effectively contribute to overcoming challenges imposed by the increasing world population. These environmentally friendly and natural substances promote vegetative growth, mineral nutrient uptake, and tolerance of plants to abiotic stresses. In the modern agriculture system, biostimulants are obtained from the different communities of naturally occurring microorganisms and the biochemical products produced by them such as organic acid, proteins, enzymes, and hormones. These substances when interacting with the plant-soil continuum enhance the availability or uptake of essential nutrients that are applied in the form of fertilizers or that are already existing in soil or crop residues. The other advanced technology used by different manufacturers is nanosurfactant additives, protein hydrolysates, humic acid, and seaweed with their different modes of action. So, in the current perspective, the use of these advanced technologies in organic farming will help to increase crop productivity, and soil fertility, protect against pathogens, and in turn, increase the income of the farmer. � 2022 Elsevier Inc.

    Conservation Agriculture for Soil Health and Carbon Sequestration in the Indian Himalayan Region
    (Springer Singapore, 2023) Rai, Ashish; Tripathi, Sumit; Bahuguna, Ayush; Rai, Sumit; Rajput, Jitendra; Gangwar, Anshu; Srivastava, Rajeev Kumar; Singh, Arvind Kumar; Singh, Satish Kumar; Shekhar, Dibyanshu; Mishra, Rahul; Sathyanarayana, Eetela; Pandey, Supriya
    Mountains the most significant agro-ecosystems that directly or indirectly support human life. The areas surrounding the hills are abundant in biodiversity and have enormous potential for sustaining Indian agriculture. It has been widely recognised that the ecological fragility and sensitivity of the Himalayas to climatic aberrations, topography, peculiar geographical features, and some of the particular identified problems, which may be soil loss, runoff, steep slopes, acidity of soils, and loss of soil nutrients, form it a very distinct region as opposed to plains in terms of socioeconomic situation. Conventional agriculture was one of the best aspects of food production during the green revolution and after India gained its independence for securing food and nutrition through intensive agricultural practices, but on the flip side, it has simultaneous effects on resource degradation and soil biodiversity. The need for food and fodder, an ever-growing population, the preservation of soil biodiversity, declining soil health, climate change, the use of unbalanced fertilisers, and decreased farm profitability all call for a paradigm shift in the agriculture sector. On the other hand, increasing the intensity of the hillside agriculture system without implementing any conservation measures greatly increases the likelihood of disastrous conditions. Conservation agriculture has long been known to improve soil health and sustain agricultural production systems by reducing environmental footprints. Between the atmosphere and the lithosphere, numerous biological and physical processes are regulated by soils. An integral aspect of soil that promotes agricultural sustainability is soil health. However, each measurement of a specific soil health parameter is always tied to a unique set of circumstances. A fundamental concern in maintaining soil health to feed an expanding population is resource conservation. Climate change is a topic of discussion on a worldwide scale in the current globalisation context. The greenhouse effect is best for life but only up to a point beyond which it becomes dangerous. Due to urbanisation, changes in land use, cropping patterns, and other factors, human influences on climate change go beyond the range of natural fluctuation. Climate change in the soil system is significantly influenced by carbon regulation in the soil. The rate of organic matter decomposition is accelerated by an increase in mean annual temperature, which affects aggregate stability, water storage capacity, and nutrient balance� all of which are crucial for healthy soil structure, soil fertility, productivity, and sustainability. In actuality, soil bacteria break down organic materials, but a change in temperature regime may change the microbial population. � The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2023.

    Current State of Knowledge in Diagnosis and Mitigation of Micronutrients Deficiency in Crop Production from an Indian Prospective
    (Nova Science Publishers, Inc., 2022) Singh, Satish Kumar; Pandey, Astha; Bahuguna, Ayush; Mohapatra, Kiran Kumar; Patra, Abhik; Sathyanarayana, Eetela; Jatav, Hanuman Singh; Jatav, Surendra Singh; Rajput, Vishnu D.
    Indian soils are fairly satisfactory with respect to total micronutrient content. But in spite of the relatively high total contents, micronutrient deficiencies have been frequently reported in many crops due to low levels of available micronutrients in soils. Based on the critical limits followed in different states of India, the status of the micronutrients deficiencies was assessed in different soils under the leadership of ICAR All India Coordinated Research Project on Micro- and Secondary Nutrients and Pollutant Elements in Soils and Plants (AICRP-MSPE). In addition to single micronutrient deficiencies, multimicronutrient deficiencies have emerged in different areas of the country over the years, posing a threat to the sustainability of agriculture. Various diagnostic procedures for micronutrients deficiency in soil and plants have been briefly discussed in this paper. In total 1421 field experiments were conducted on specific crops to determine the critical nutrient concentration of different micronutrients. Based on field experiments and crop response to micronutrients, generalized transition zones were worked out for different nutrients across the soil types. Various factors affecting micronutrients availability in soil and deficiency symptoms of micronutrients have been discussed along with their mitigation strategies. Hence this paper represents the current status of micronutrients in Indian soil with emerging solutions for micronutrient deficiency. � 2022 by Nova Science Publishers, Inc.

    Evaluating combined effect of different coated urea with PGPR on yield and nitrogen use efficiency in lowland rice by regression model and principal component analysis approach
    (Taylor and Francis Ltd., 2023) Sharma, Sachin; Bahuguna, Ayush; Parihar, Manoj; Yadav, Janardan; Singh, Surendra
    Nitrogen (N) loss is a key problem in rice fields, which results in low nitrogen use efficiency (NUE) of applied N and could be a major limitation from economic and environmental perspectives. In order to improve the NUE, use of slow or controlled released N fertilizers could be a potential alternative to the conventional N inputs. With this objective to evaluate the effect of different slow-release fertilizers on NUE and grain yield of rice, a pot experiment was conducted during kharif 2017 at Department of Soil Science and Agricultural Chemistry, Institute of Agricultural Sciences, Banaras Hindu University Varanasi. The experiment comprised thirteen treatments including control, Polymer (PCU) and Neem coated urea (NCU) and their combination with Farm yard manure (FYM) and Plant growth promoting rhizobacteria (PGPR). The combined application of PCU, NCU, FYM and PGPR in treatment T12 provided highest grain yield 47.98 gpot?1and followed by T8 46.60 gpot?1. The result showed that, compared with the PCU treatment T2 (PCU100 Split), the Agronomic efficiency (AE) and Apparent nitrogen recovery efficiency (ANR%) of the mixed doses of coated urea treatment T12 (PCU50 NCU50 FYM10 PGPR Basal) increased by 20.38% and 28.48% respectively. Therefore, application of FYM and PGPR with coated urea improved rice yield, nutrient uptake and their use efficiency and potentially recommended in eastern plain of the Indo-Gangetic Plain for the sustainable production of rice crop. � 2022 Taylor & Francis Group, LLC.

    (Nova Science Publishers, Inc., 2022) Sharma, Sachin; Singh, Surendra; Bahuguna, Ayush; Yadav, Bharti; Barthwal, Akshita; Khatana, Raghu Nandan Singh; Pandey, Astha; Thakur, Rajneesh; Jatav, Hanuman Singh
    The increasing global population accelerates world food demand with limited land resources. It shifts the research towards higher productivity with higher fertilizer use on large scale but with high economic inputs. This promotes the use of Nanotechnology in fertilizer industries which offers higher production with the desired customization in nutrient values, high reactivity, changeable surface area, high nutrient use efficiency because of its different physic-chemical properties. Nanoparticles facilitate a smart delivery system of nutrients with the targeted cellular approach in plants as well as in the rhizosphere. The nanopolymers and nano fertilizers also benefit the plant in stress resistance, crop nutrient quality and improve water use efficiency. However, the behavior of nanoparticles to surpass the food chain, its concentration and toxicity in edible products is still a topic of research. The present chapter deals with their mechanisms, controlled release pattern, particle morphology, chemical kinetics, interaction with soil colloids as well as the effect on the microbiome with lesser amount application in the field and proves to replace the current conventional fertilizers with sustainability and minimal environmental risks. � 2022 by Nova Science Publishers, Inc.

    Soil Pollution Due to Sewage Sludge and Industrial Effluents
    (Springer Science and Business Media Deutschland GmbH, 2022) Bahuguna, Ayush; Singh, S.K.; Sharma, Sachin; Arvind; Pandey, Astha; Dadarwal, Basant Kumar; Yadav, Bharti; Barthwal, Akshita; Khatana, Raghu Nandan Singh
    In recent times the issue of soil pollution is becoming important as all the nutrient are taken up by plant from the soil. The wastewater treatment produces sewage sludge as an end product, but its primary source is from domestic effluents as well as industrial effluents. Water makes up more than 90% of the sewage water produced in India, 40�50% organics, 30�40% inert compounds, 10�15% bio-resistant organics, and 5�8% miscellaneous components make up the solid fraction. Rapid urbanisation, industrialisation and increasing population generate a huge amount of waste and the waste from industry and the sewage released into the soil as a source of irrigation without being treated properly causes accumulation of toxic heavy metals, persistent organic pollutant, microplastics and high salt that leads to the reduction in the quality of the soil. Similarly, the effluents released by the industries such as distillery, tanning, textile also contains different sources of heavy metals, sodium and other salts and organic chemicals. This chapter providesa detailed aspect of soil pollution from the industry as well as sewage sludge. � 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.
