“…The differences were presumed to be associated with soil nutrients. Biochar's contribution in increasing the availability of soil nutrients has been well recognized, especially in poor soils (Agegnehu et al, 2016) Lower number of panicles per hill was not associated with more grains per panicle (Figure 4). This result indicates that number of grain per panicle and number of panicles per hill was not correlated.…”

“…Recent research has identified several environmental and agricultural benefits of applying biochar, including carbon sequestration for reducing carbon emission into the atmosphere (Mašek et al, 2013;Mukherjee and Lal, 2013;Zhang and Ok, 2014;Jiang et al, 2016;Wang et al, 2016); phytoremediation of soil contaminants (Ahmad et al, 2014;Mohan et al, 2014;Wiszniewska et al, 2016); adjusting soil physicochemical and biochemical properties for agriculture (Herath et al, 2013;Githinji, 2014;Bai et al, 2015;Abujabhah et al, 2016;Bera et al, 2016;Haider et al, 2017); creating soil health by inducing growth of beneficial and suppressing pathogenic organisms (Lone et al, 2015;Abujabhah et al, 2016;George et al, 2016;Xu et al, 2016); and improving crop growth and yield (Vaccari et al, 2015;Agegnehu et al, 2016).…”

Biochar improves soil quality. However, most biochar research has focused on aerobic soil conditions. The objective of this research was to evaluate the agronomic benefits of applying biochar on unfertilized rice crop, cultivated under transitional anaerobic soil conditions during early vegetative growth phase, and gradually drying out to fully aerobic at harvest time. This transitional condition is typical during the rice growing season of the tropical riparian wetlands in Indonesia. Biochar was applied in the form of fine powder at rates of 0, 0.4, 0.8, and 1.2 Mg.ha -1 ; no inorganic fertilizer was applied. The research was conducted on a farmer's paddy field at Pemulutan Ulu Village, South Sumatra, Indonesia from July to November 2016. Results indicated that applying biochar at rates up to 1.2 Mg.ha -1 increased rice yield, but restrained shoot elongation rate and plant height. During the vegetative growth phase, applying biochar significantly increased the number of tillers, leaves, shoot dry weight, and root dry weight. Biochar significantly affected the following yield components: number of tillers, percentage of productive tiller, number of grains per panicle, panicle density, percentage of filled grain, and weight of 1,000 grains.

“…This process improves both the growth and yield of the plant. Besides decreasing soil bulk density, Agegnehu et al [28] added that application of compost can increase soil pH, soil organic content (SOC), N content, available P, K, Ca, Mg, Na, and S. Compost addition to soil has also been shown to increase yield of crops similarly to, or beyond the effects of, mineral fertilizer application [36]. However, annual application of high doses of compost had an inhibitory effect on enzyme activity and crop yields [37].…”

“…Agegnehu et al [28] listed some extensive scientific evidence demonstrating that additions of low application rates of biochar into bedding plant container media in the greenhouse, or as amendments to field soils, improve plant growth and yields significantly, regardless of nutrient supply. For example, Vaccari et al [29] reported increases in the rates of germination, growth, and yields of tomato plants grown in a range of concentrations of a soil commercial container medium amended with biochar.…”

This paper reviews the role of Natural Farming as an ecological farming method to produce organically grown food of safe and high quality and at the same time improve soil quality and soil health. Currently, there is a dearth of information on the effects of Natural Farming approach on black pepper farms particularly in Sarawak, Malaysia. Previous studies on other crops had indicated positive outcome using the Natural Farming method. Thus, this paper discusses the essential role of effective microorganisms in Natural Farming and their potential in pepper cultivation. Through the action of effective microorganisms, this approach should be able to transform a degraded soil ecosystem into one that is fertile and has high nutrients availability. The mixed culture of effective microorganisms applied must be mutually compatible and coexist with one another to ensure its favorable establishment and interaction in the soil. Therefore, it is anticipated that introducing Natural Farming in black pepper cultivation can enhance the predominance of effective microorganisms in the soil, which in turn could lead to promising growth and yield of the crop.

Soil fertility depletion has significantly reduced the yields of various crops in Ethiopia, mainly the yield of malt barley in the district. To address this issue, integrated applications of vermicompost and mineral nitrogen (N) fertilizers were tested. Therefore, this study aimed to evaluate the effects of vermicompost and mineral nitrogen fertilizers application on malt barley yield (Hordeum distichum L.), soil properties, and economic benefits. The experiment was arranged in a randomized complete block design with three replications. The treatments were nine in various combinations of vermicompost (VC) and N fertilizer (N): (69 kg N; 0.79 t VC + 58.65 kg N; 1.59 t VC + 48.30 kg N; 2.39 t VC + 37.95 kg N; 3.19 t VC + 27.60 kg N; 3.98 t VC + 17.25 kg N; 4.78 t VC + 6.90 kg N; 5.31 t VC ha−1 and control). The highest soil pH was recorded by applying 5.31 t of vermicompost ha−1 alone. The highest total nitrogen (0.34%), available phosphorus (15.58 mg kg−1), grain yield (4950 kg ha−1), and net benefit (4255.74 USD) were recorded from the application of 2.39 t VC plus 37.95 kg N, while the highest soil organic carbon (3.38%) and cation exchange capacity (26.17 cmol (+) kg−1) were recorded from 3.19 t VC plus 27.60 kg N ha−1 compared to the control. This study concludes that applying 2.39 t VC and 37.95 kg N ha−1 in combination improves soil fertility, malt barley yield, and economic benefits for smallholder farmers in the study district and adopts this in similar soil types and agroecologies.
