After the green revolution excessive use of inorganic fertilizers increased, which resulted in affecting the activities of soil microflora and macrofauna, thus posing an environmental risk and decreasing crop production. The use of organic sources which include biochar, carpet waste, FYM (Farmyard manure) and PGPR (Plant growth promoting rhizobacteria) may act as an important tool to sustainably increase soil organic matter, crop yield and improve soil health on a long-term basis. The results of application of biochar, carpet waste, farm yard manure (FYM) and PGPR showed that the combined application of biochar, carpet waste and PGPR significantly improved soil properties such as organic carbon, nitrogen(N), phosphorus(P), potassium(K), dehydrogenase, alkaline phosphatase activity and microbial population. The enzymatic activity of soil was highly positively correlated with the physicochemical properties of soil. Therefore, it can be concluded that the combination of biochar, carpet waste, FYM and PGPR may increase and sustain the soil properties and crop productivity over time.

Sustaining soil health cannot be divorced from sustainable crop production. Organic, or natural, farming is being promoted as a good sustainable agriculture practice. One aspect of organic farming that could significantly enhance and sustain soil health, soil quality, and crop productivity is the use of high-quality soil conditioners or organic amendments produced from agro-wastes. Thus, the objective of this study was to characterize the chemical and biological properties of selected agro-wastes with potential for use as organic amendments in sustaining soil health. Standard procedures were used to produce and characterize the soil conditioners, namely fermented plant juice (FPJ), fermented fruit juice (FFJ), palm kernel shell (PKS) biochar, and kitchen waste (KW) compost. The fermented juices (FPJ and FFJ), PKS biochar, and KW compost exhibited chemical and biological properties with good potential as soil conditioners or organic amendments to sustain soil health. The fermented juices contained important microbes that can solubilize P and K in soil for crop use. The high pH and C content of the biochar and compost and the high cation exchange capacity of the biochar are good indicators of the potential of these materials to sustain soil health in terms of the liming effect of acid soils, nutrient and water retention, nutrient reserves, and a suitable habitat for microbial life. Moreover, the organic amendments contain reasonable amounts of macro- and micro-nutrients, which could be released to increase soil fertility. Despite these potential benefits, field application of these organic amendments is necessary to evaluate their effects on soil health and crop production in both the short and long term.

The world vision of no hunger target, food security, and zero poverty followed by raising standards of living of rural people through agricultural transformation is the greatest challenges faced by the agricultural planners worldwide. Due to the alarming state of population growth and cultivable land scarcity, change in agronomic practices which could bring a significant effect on crop production and productivity is urgently needed. The concept of using different sources of plant nutrients combined to check nutrient depletion, maintain soil health, and crop productivity, called INM, has a bright solution in this area. Recently several researchers introduced that integrated use of inorganic fertilizers, organic fertilizers, green manure, and bio-fertilizers is becoming an effective practice not only for increasing crop production and productivity but also for the better crop and soil health. In addition, INM helps to increase the activity of soil microorganisms and improves the soil physical, chemical and biological properties. So, INM create an economic eco-friendly environment by reducing the dependence on inorganic chemical fertilizers and improving the soil fertility, optimizing crop yield, maximizing profitability and ultimately making the agriculture sustainable. Lastly, INM is one of the good agricultural practices which needs to be followed by every conscious individual in order to maintain soil health, nutrient balance and to make the agriculture and environment more sustainable.  Int.

Nutrient management influences soil health and crop productivity. Sustained crop production re-quires specific nutrient management options after a certain period. The objectives of this investigation were to examine the effects of inorganic and organic fertilization on yields and soil carbon budget under rice based cropping patterns in Bangladesh. The research data and informationhave been gen-erated based on previouslypublished, unpublished sources and own concept.Omission of K or im-balanced K are more influential for reduction in grain yield up to 47% in Boro (dry) season but N was most limiting up to 35% in T. Aman (wet) season. With existing fertilizer rates for growing rice, the balances of N and K are always negative. Balanced chemical fertilizer (NPKSZn) can be an option for improving crop productivity and maintain soil quality. Net ecosystem carbon (C) balances are posi-tive when 3 t ha-1 cow dung (CD), 2 t ha-1 poultry manure (PM) and 2 t ha-1 vermicompost (VC) are used in combination with chemical fertilizers. Soil amendments with organic nutrient sources (rice straw, CD, PM, VC, legume crops) and rice based cropping patterns such as T. Aman-Mustard-Boro, Boro-Fallow-Fallow, Jute-T. Aman-Fallow, Wheat-Mungbean-T. Aman, Grass pea- T. Aus-T. Aman and Potato-Boro-T. Aman can be beneficial in improving soil C budget, soil nutrient ratio, total crop production and maintenance of environmental health that will meet SDGs goal.

In the emerging global economic order in which agricultural crop production is witnessing a rapid transition to agricultural commodity production, potato is appearing as an important crop, poised to sustain and diversify food production in this new millennium. Temperature and unpredictable drought are two most important factor affecting world food securities and the catalyst of the great famines of the past. Decreased precipitation could cause reduction of irrigation water availability and increase in evapo-transpiration, leading to severe crop water-stress conditions. Increasing crop productivity in unfavourable environments will require advanced technologies to complement traditional methods which are often unable to prevent yield losses due to environmental stresses. Various crop management practices such as improved nutrient application rate, mulching, raised beds and other improved technology help to raise the productivity. Conservation farming practices play important role to restore soil and enhancing soil health and play important role to combat climate change issue.

The sustainable production of food faces formidable challenges. Foremost is the availability of arable soils, which have been ravaged by the overuse of fertilizers and detrimental soil management techniques. The maintenance of soil quality and reclamation of marginal soils are urgent priorities. The use of biochar, a carbon-rich, porous material thought to improve various soil properties, is gaining interest. Biochar (BC) is produced through the thermochemical decomposition of organic matter in a process known as pyrolysis. Importantly, the source of organic material, or ‘feedstock’, used in this process and different parameters of pyrolysis determine the chemical and physical properties of biochar. The incorporation of BC impacts soil–water relations and soil health, and it has been shown to have an overall positive impact on crop yield; however, pre-existing physical, chemical, and biological soil properties influence the outcome. The effects of long-term field application of BC and how it influences the soil microcosm also need to be understood. This literature review, including a focused meta-analysis, summarizes the key outcomes of BC studies and identifies critical research areas for future investigations. This knowledge will facilitate the predictable enhancement of crop productivity and meaningful carbon sequestration.

Drought conditions marked by water deficit impede plant growth thus causing recurrent decline in agricultural productivity. Presently, research efforts are focussed towards harnessing the potential of microbes to enhance crop production during drought. Microbial communities, such as arbuscular mycorrhizal fungi (AMF) and plant growth-promoting rhizobacteria (PGPR) buddy up with plants to boost crop productivity during drought via microbial induced systemic tolerance (MIST). The present review summarizes MIST mechanisms during drought comprised of modulation in phytohormonal profiles, sturdy antioxidant defence, osmotic grapnel, bacterial exopolysaccharides (EPS) or AMF glomalin production, volatile organic compounds (VOCs), expression of fungal aquaporins and stress responsive genes, which alters various physiological processes such as hydraulic conductance, transpiration rate, stomatal conductivity and photosynthesis in host plants. Molecular studies have revealed microbial induced differential expression of various genes such as ERD15 (Early Response to Dehydration 15), RAB18 (ABA-responsive gene) in Arabidopsis, COX1 (regulates energy and carbohydrate metabolism), PKDP (protein kinase), AP2-EREBP (stress responsive pathway), Hsp20, bZIP1 and COC1 (chaperones in ABA signalling) in Pseudomonas fluorescens treated rice, LbKT1, LbSKOR (encoding potassium channels) in Lycium, PtYUC3 and PtYUC8 (IAA biosynthesis) in AMF inoculated Poncirus, ADC, AIH, CPA, SPDS, SPMS and SAMDC (polyamine biosynthesis) in PGPR inoculated Arabidopsis, 14-3-3 genes (TFT1-TFT12 genes in ABA signalling pathways) in AMF treated Solanum, ACO, ACS (ethylene biosynthesis), jasmonate MYC2 gene in chick pea, PR1 (SA regulated gene), pdf1.2 (JA marker genes) and VSP1 (ethylene-response gene) in Pseudomonas treated Arabidopsis plants. Moreover, the key role of miRNAs in MIST has also been recorded in Pseudomonas putida RA treated chick pea plants.

SUMMARYCalcium cyanamide is a nitrogenous fertilizer used predominantly for over a century in field and glasshouse vegetable and salad production. The current review draws together, for the first time, knowledge concerning the biological properties of the compound that benefit crop production by encouraging sustainable soil health and quality. This is achieved through the increase of microorganisms antagonistic to plant pathogens. The review also reports on the natural occurence and degradation of cyanamide. The literature survey provides a perspective of research from the early 1900s to current studies. This identifies that nitrogen is released steadily into the rhizosphere from this fertilizer. Calcium is also readily available for plant roots and promotes the alkaline soil conditions beneficial to benign microorganisms. Consequently, soil suppressiveness towards organisms such asPlasmodiophora brassicae, the cause of clubroot disease in brassicas, develops. The effects of calcium and accompanying changes in soil pH values are discussed in relation to the life-cycle stages ofP. brassicaeand the development of clubroot disease. Formulations of calcium cyanamide contain the dimeric form, dicyandiamide. This compound slows soil nitrification and subsequent nitrate leaching into ground waters, reducing potential pollution. Calcium cyanamide is normally used for growing specialized fresh produce and is not available in quantities comparable with ammoniacal fertilizers. It is contended, however, that it has properties deserving wider assessment because of their implications for sustainable cropping.


Agriculture is the most important sector of Indian Economy. Indian agriculture sector provides employment to 50% of the countries workforce. India is the world's largest producer of pulses, rice, wheat, sugarcane, pomegranates etc. The current scenario of agriculture business in India is not up to the mark as expected. There are number of reasons which causes less yield in the agriculture such as unpredictable environmental conditions, excess use of fertilizers (cost is increasing day by day), increased draught frequency and its severity, increasing labor rate, less difference between the income and expenditure, ripeness of soil, influenced suspensions, non-appropriate water management, diseases on crops, invasion of animals and so on. There is need to find the ways which makes the use of Information Technology (IT) concepts and tools wherever possible for increasing automation in the agriculture business, which results in the efficient and effective outcome of agriculture i.e. higher yields. The production efficiency can be increased significantly with technological advancement in agriculture. Internet of Things (IoT) is a novel design approach for precision farming. Farming has seen number of technological transformations in the last decade. By using various smart agriculture gadgets, farmers have gained better control over the process of raising the growing crops and livestocks. One of the major issues which cause fewer yields is the soil health. This paper mainly analyses/reviews the problems related to the soil health (soil fertility), which is a main obstacle in the crop production. Also this study focuses on the use of IoT applications in precision farming. It gives an overview of the relation between crop productivity and soil health

Soil physico-chemical properties are an important phenomenon for sustainable crop production and maintenance of optimum soil health. Hence, a laboratory measurement was conducted with soil samples of three years long experimental field of the Department of Soil Science, Bangladesh Agricultural University, Mymensingh to assess the changes in five selected soil physico-chemical properties viz. soil texture, bulk density, soil pH, total nitrogen and organic matter. The experiment was laid out in a split plot design with two water regimes (continuous flooding and alternate wetting & drying) in the main plots and five fertilizer treatments (N0 - control, N1- 140 kg N/ha as PU, N2- 104 kg N/ha as USG (2× 1.8 g/ 4 hills), N3 - 5 t CD + PU @ 140 kg N /ha on IPNS basis and N4- 5 t CD + USG (2× 1.8 g/ 4 hills @ 104 kg N/ha)) in the subplots under rice-rice cropping pattern with three replications. After three years, soil samples were collected at 0-5 and 5-10 cm soil depths for measuring bulk density and at 0-10 cm depth for other soil properties and analyzed. Results found that % sand, % silt, % clay, bulk density and soil pH was not changed significantly compared to initial status. Percentage of total nitrogen and organic matter was significantly affected by irrigation and fertilization. Total nitrogen (%) was higher in AWD whereas organic matter (%) was higher in CF practice. The highest total nitrogen (%) and organic matter (%) was found in N4 treatment in which USG was applied in combination with cowdung as organic manure. It can be suggested that N4 treatment was formed good combination for sustaining chemical properties of soil. Further long- term experimentation will be needed to know the changes in soil properties for sustainable crop production and improving soil health. Asian Australas. J. Biosci.

This paper deals with verification of the effect of fermented manure (with and without Z'fix activators) and soil activators (PRP Sol) on a soil properties change. Their application should lead to a change in physical, physical-chemical and biological properties of soil, along with ecological material fixation, improved water retention and infiltration, reduction of soil susceptibility to water erosion and decreased soil tillage energy requirements. Field trial was established in Sloveč in Central Bohemia in the year 2014. The experiment was divided into several variants and was designed as multiannual. Z›fix activator was used as a biological transformation activator of manure. PRP Sol was used as a soil activator. In order to verify the effect, soil infiltration, cone index, bulk density and draft of tillage implement were measured. Measurements have shown a beneficial effect of the activators with regard to the decomposition of organic matter. Consequently, changes in soil properties and a reduction of draft at tillage operations developed. Finally, the effect should evolve gradually with a prolonged activator treatment.
