Sustainable food production is one of the major challenges of the twenty-first century in the era of global environmental problems such as climate change, increasing population and natural resource degradation including soil degradation and biodiversity loss. Climate change is among the greatest threats to agricultural systems. Green Revolution though multiplied agricultural production several folds but at the huge environmental cost including climate change. It jeopardized the ecological integrity of agroecosystems by intensive use of fossil fuels, natural resources, agrochemicals and machinery. Moreover, it threatened the age-old traditional agricultural practices. Agriculture is one of the largest sectors that sustain livelihood to maximum number of people and contribute to climate change. Therefore, a climate-smart approach to sustainable food production is the need of hour. Traditional agriculture is getting increased attention worldwide in context of sustainable food production in changing climate. The present article advocates traditional agriculture as a climate-smart approach for the sustainable food production and also deliberates the correlation between climate change and agriculture.

“…In contrast the solubility and /or availability of RP were increased by increasing the rate of applied elemental sulphur and/or organic manure. Another study conducted by Yadav et al [8] who reported that P availability in soil and absorption by wheat crop was noticed with incorporation of RP and organic compost. Rahman et al [11] suggested that solid rock phosphate with 100 % acidulated as amendment significantly promoted wheat crop yield and P use efficiency in calcareous soil.…”

“…As fertilizer is the most important input, its availability at affordable prices is a necessity if crop production is to be increased on sustainable basis [7]. Indeed, rock phosphate (RP) is a basis source of P, but un-fortunately we lack reliable technology to make it appropriate for local soils that is alkaline [8]. However, in view of increasing energy cost and the limited reserves of rock phosphate, the prices of phosphatic fertilizers are not likely to reduce.…”

“…The direct addition of RP to be found highly effective in acidic soils with low pH which assist to mobilize the RP and enhance P bioavailability from soil to plant, but this approach is failure in alkaline and/or calcareous soils because of high pH [15,16]. A significant number of literatures have reported the solubility and bio-availability P from rock phosphate might be affected due to influence of soil pH, particle size of RP, and quantity of P and Ca in soil pool [8,17,18]. To overcome the problem, RP is integrated with organic materials (OM) namely, farm yard manure, poultry manure, compost and bio-char etc to bring P in to soluble form which can be taken up by the plant [19].…”

The aim of this study was to assess the solubility of phosphorus from rock phosphate incubated with farmyard manure under laboratory condition. The treatments were factorial combination of three rates each of RP (0, 2, and 4 tons ha-1) and farm yard manure (0, 10 and 20 tons ha-1). These treatments were applied to 100 g soil contained in plastic vials with three replications. Seven such sets of 27 vials each were prepared to represent seven incubation periods namely 0, 15, 30, 45, 60, 75, and 90 days. The results showed that Olsen -P improved significantly with increasing rate of rock phosphate from 0 to 4 tons ha-1 and that of farmyard manure from 0 to 20 tons ha-1. Initial available P content of soil was 4.59 mg kg-1 which enhanced up to 10.55 mg kg-1 as a result of 90 days incubation. Addition of rock phosphate and farmyard manure increased it to maximum value of 23.03 mg kg-1 with incorporation of rock phosphate at 4 tons ha-1 and farmyard manure at 20 tons ha-1. Thus, positive response of rock phosphate and farmyard manure was clearly evident on Olsen-P values due to enhancement of soil organic matter. It is concluded that there is potential for utilization of local rock phosphate by solubilising the P using farmyard manure. Soil incubation for the prolonged period of 90 days with rock phosphate and farmyard manure helped to enhance the solubility of P from rock phosphate. It is recommended that further experiments may be performed along with different bio-char, vermicompost, organic acids etc. which can help solubilise P from rock phosphate under field trials. For the first time, the feasibility of using agricultural fertilizer (manure) to increase the solubility of phosphorus from rock phosphate is experimentally substantiated. The practical value of this study is to achieve two effects simultaneously, namely, improving the fertility of agricultural lands depleted in phosphorus and utilizing agricultural fertilizer (manure).

“…In Pakistan, there are several poultry farms that produce a large amount of poultry waste daily and all poultry farms' owners are facing problems due to lack of storage, disposal and handling facilities. Problems related to regulatory pressure, urban invasion, fly control, and proximate land base for waste disposal compel the search for an alternative waste management system (Yadav et al 2017). The commonly used livestock solid waste disposal techniques include onsite burial, landfill, incineration and composting.…”

Purpose The purpose of this study was to assess the efficacy of inorganic additives during the humification of poultry waste and rice husk. Methods Poultry waste mixture was treated with aluminum sulfate 3% and rock phosphate 2% during co-composting of mixture in mechanical composter and evaluated the potential of humification and compost nitrogen mineralization in incubation and pot study. Results The mesophilic to thermophilic phase of composting mixture is prolonged due to the rise in temperature, pH and ammonia that steadily decrease near the maturation phase. The humification rate (HR), humification index (HI), degree of polymerization (DP) and cation exchange capacity (CEC) increased in enriched compost as compared to unenriched with the composting process. The germination index (GI) of enriched compost (C/N:10.8) was significantly greater than unenriched compost (C/N:23.43). These all maturity indices, i.e., C/N, CE, HI, DP, HR revealed the significant correlation with each other. In the incubation study, nitrogen mineralization was also evaluated and nitrogen was applied at the rate of 50 kg-N/ha using the enriched and unenriched compost and found high mineralization in enriched compost due to low C/N. A laboratoryscale pot experiment was also conducted, applied the compost at a rate of 100 kg-N/ha and recorded the encouraging results in growth and nutrition value of Abelmoschus esculentus plant. Conclusion It was concluded that use of additives have a significant impact on humification of poultry waste.
