“…The world population has reached 7.6 billion people and is expected to reach 8.6 billion by 2030, 9.8 billion by 2050, and 11.2 billion by 2100 (Gerliani, Hammami & Aïder, 2019;Tripathi et al, 2019). To meet the global anticipated food demand caused by this population growth, various agricultural practices have been proposed and tested (Godfray et al, 2010), including the excessive application of chemical fertilizers, pesticides, and herbicides (Ju et al, 2007); large-scale utilization of water resources (Tilman et al, 2002); and intensive plowing (Koch & Stockfisch, 2006).…”

We used a constant total N application base rate to conduct a two-year field experiment comparing the effects of three organic fertilizers (rapeseed meal (RSM), soybean meal (SBM), and cattle manure (CM)) on the crop yield, economic growth, and soil quality of a winter wheat-summer maize rotation system. Winter wheat and summer maize in rapeseed meal treatment (RSMT), soybean meal treatment (SBMT), and cattle manure treatment (CMT) showed yield increases of 161%, 299%, and 256%, respectively, when compared to no organic fertilizer treatment (CK) (P < 0.05). The annual net incomes of SBMT and CMT were 1.46 and 1.42 times higher, respectively, than RSMT. Compared to the results of the CK group, RSM, SBM, and CM stimulated the soil physically, chemically, and biologically. We found the highest soil macroaggregate proportions, soil organic matter (SOM) levels, total N (TN) levels, and phospholipid fatty acid (PLFA) levels in SBMT. The highest soil pH, microbial biomass carbon (MBC) levels, and microbial biomass nitrogen (MBN) levels were observed in CMT. We used a soil quality index (SQI) to evaluate soil quality. After the two-year fertilization treatments, we calculated the SQI using a minimum data set (MDS). We used SOM levels and actinomycete quantity for the MDS properties. The SQI values were significantly different across the four treatments, with the highest values occurring in SBMT, then CMT and RSMT. In conclusion, SBM and CM were more effective than RSM at maintaining crop yield, economic growth, and soil quality.

Effects of Applying Liquid Swine Manure on Soil Quality and Yield Production in Tropical Soybean Crops (Paraná, Brazil)

Brazil is one of the main producers of pork meat in the world. It is well-known that the agricultural sector is a key component of the economic development of this country, where super-intensive fields are only competitive in the globalized market. For the farmers, the application of swine manure to fertilize the soil can increase the yearly income, but it also may cause serious environmental problems related to soil health and soil quality. In this research, we assessed the effects of applying liquid swine manure in a tropical soybean (Glycine max) plantation to better understand when this technique stops being effective and starts causing a threat to soil health and quality. Therefore, we compared values of several soil properties and the soybean yield on treated fields at 10 random points belonging to 7 different plots that were treated with the liquid swine manure over a period ranging from 0 to 15 years. The results showed a positive linear trend in soybean production from 2.45 to 3.08 Mg ha−1 yr−1. This positive trend was also recorded for some key soil parameters such as porosity and exchangeable cations content (Ca, Mg, K, and Al). Additionally, positive effects were also found for organic matter content after 10 years of application. Our findings suggest that the use of liquid swine manure has a positive effect on soybean yield and improves soil quality, particularly on mixed farms where pigs are intensively raised nearby cultivated fields.

“…Energy is the primary catalyst of any country's socioeconomic development. The demand of energy is increasing rapidly as the World's population is increasing and it has reached upto 7.4 billion in 2016 [8]. Since the dawn of the industrial revolution, fossil fuel is the chief contributor to worldwide energy demand and remains as primary source of the worldwide energy supply scenario [9], [10], because the consumption of crude oil (34.01%) is higher when compared with other resources like nuclear (5.28%), hydro (6.54%), natural gas (24.13%) and coal (30.02%) [11].…”

Increasing demand of the carbon fuels in daily life and the global environmental degradation has led to the biodiesel production from non-edible oils because they has high potential as ecological, clean, facile and renewable fuel. In present study, oil is extracted from dried Eruca sativa seeds using mechanical expellers, the oil yield obtained is calculated. By alkaline transesterification, the obtained oil is converted into biodiesel. The physicochemical properties of Eruca sativa biodiesel are tested following ASTM test methods, all the properties satisfies and meet the ASTM D-6751 biodiesel standard specifications. The gas chromatography technique is used for the analysis of fatty acid composition of the biodiesel, which shows that the erucic acid has higher percentage composition. Emission characteristics (i.e. carbon monoxide, carbon dioxide, hydro carbon, nitrogen oxide and smoke) of diesel engine are analyzed for the biodiesel and its blends (i.e. B10, B20, B30, B40 and B100) and are compared with the petroleum diesel. From the emission results obtained it is observed that, the CO and CO2 emissions are lower for B10 and B20 blends whereas the HC emissions are lesser than diesel for all the blends. For B10, B20 and B30 blends the NOX emission and smoke opacity has been reduced when compared to diesel.
