“…Kumar and Gupta 32 observed a similar specific unit weight of grains of the RHA, with a value of 1.98 g/cm 3 . The incorporation of RHA in the soil leads to a decrease in its density, as observed by Qu et al 33 . However, based on the results, rice husk ash can increase soil quality, in terms of stability and resistance.…”

This study evaluates the use of rice husk ash (RHA)-eggshell lime (ESL) and RHA-commercial lime (CL) as alternative binders for clayey soil stabilization, as well as the performance of soil-binder mixtures under acidic attack. A central composite design was carried out to analyze the reactivity by batch tests with a sulfuric acid solution. Physical and mechanical behavior was evaluated by compaction test and unconfined compressive strength (UCS). Reactivity tests demonstrated better neutralization of contaminant acidity for mixtures with ESL. The highest compressive strength, reactivity and partial encapsulation of toxic elements are associated with application of 30% RHA and 6% ESL in the soil. A C–S–H gel is observed in poorly crystalline phases through the XRD pattern. The application of RHA-ESL in soils exposed to acidic attack has environmental feasibility. Analysis of RHA grinding processes combined with the mixture strength over time, and its application tests in impermeable barriers, in landfills, are recommended.

“…Biochar application leads to improvement in soil structure and nutrient absorption potential (Wang et al, 2016). Qu et al (2014) reported a decrease in soil bulk density and an increase in soil moisture content after a ricehusk ash application. Combined application of biochar with other organic amendments (e.g., organic manure, crop residue) was also reported to improve soil WHC, moisture content, soil pH, electrical conductivity and soil nutrients (Kameyama et al, 2016;Singh et al, 2019bSingh et al, , 2019c.…”

Compatible package-based agriculture systems: an urgent need for agro-ecological balance and climate change adaptation

Besides contributing majorly in the growth of a country, agriculture is one of the severely affected sectors at present. Several modifications and adaptations are being made in agricultural practices to cope-up with the declining soil fertility and changing climate scenarios across the world. However, the development and adoption of a single agricultural practice may not help in the holistic mitigation of the impacts of climate change and may result in economic vulnerability to farmers. Therefore, it is high time to develop and recommend a group of agricultural practices i.e., package-based agriculture system having some compatibility for one another in the long term. In this article, a viewpoint has been given on some emergent agronomic practices adopted in the tropical agroecosystems which have potential to be developed as compatible agricultural package in combination. Moreover, we also emphasized on exploring some key indicators/environmental factors to assess the compatibility of different agronomic practices. For identifying the research transition from single to combined agricultural practices, a bibliometric analysis was performed by using conservation agriculture (CA), the system of rice intensification (SRI), organic agriculture and soil (biochar) amendment as the major agronomic practices being used for improving agroecological services such as improving nutrient cycling, soil fertility and crop productivity as well as climate change mitigation. The results revealed that scientific communities are now paying attention to exploring the role of combined agricultural practices for agro-ecological balance and climate change adaptation. Moreover, the limitations of the adoption of agronomic packages under different agro-climatic zones have also been highlighted. The recommendations of the study would further help the environmental decision-makers to develop potential measures for climate change mitigation without compromising the agro-ecological balance.

“…According to a study, Qu et al (2014) stated that there was a statistically significant increase in plastic limit values with the application of different doses of rice husk ash to the soil, while Stanchi et al (2015) stated that the plastic limit values in the upper soil horizons were higher than the lower horizons, and this situation was related to the organic matter content in the surface layer.…”

This study was carried out to determine the effects of wheat straw (WS), hazelnut husk (HH), humic acid (HA) and polyacrylamide (PAM) treatments on consistency limits (liquid limit (LL), plastic limit (PL), plasticity index (PI)) in two soils with sandy loam and clayey loam in texture. Soil samples used in the study were taken from two different areas of land (0-20 cm) from Samsun province's Bafra district. WS (0, 2%, 4%), HH (0, 2%, 4%), HA (0, 200 and 1000 ppm) and PAM (0, 30 and 90 ppm) were used in this study that was conducted in a split plots experimental design with three replications. According to the results; it was determined that the liquid limit, plastic limit and plasticity index values increased with the application of organic and synthetic conditioners in both soil texture, and the effect was realized as WS>HH>HA>PAM. It was observed that the highest dose application was the more effective in both soil texture, except for PAM.
