“…Regardless of whether the amendments were incorporated or on the surface, the combination of the wood biochar and chicken manure compost significantly increased soil fertility, and plant and root biomass. Plant biomass yield increases of 14-70% compared to the mineral fertilised soils were of similar scale to other studies using combined biochar and compost (Agegnehu et al 2015;Berek et al 2018;Cao et al 2018;Liu et al 2019;Schulz and Glaser 2012). Plants grown in biochar and compost amended soils were deemed more effective at accessing and using nutrients than that the controls (Agegnehu et al 2016a;Berek et al 2018;Manolikaki and Diamadopoulos 2019;Schulz and Glaser 2012).…”

“…They also provided more P (0.75 times) and K (0.79 times) than the fertiliser for the Andisol. The compost component of the combination was more likely to contribute the most available nutrients (Liu et al 2019;Radin et al 2018). At harvest, the soil N was higher in the amended 0-10 cm soil for the papaya trials, but was not consistent for the Chinese cabbage trials.…”

“…Attempts to examine this effect under different soil types, crops, biochar and compost types and climates often found the highest rate of biochar and compost combinations substantially increased crop yields and improved soil properties (Agegnehu et al 2017;Di et al 2019;Doan et al 2015;Kammann et al 2016;Manolikaki and Diamadopoulos 2019;Sadegh-Zadeh et al 2018). Recent studies have ascertained that the combination is superior to the amendments on their own due to increased water-holding capacity, increased nutrient retention and nutrient use efficiency (especially N), improved soil pH and CEC, decreased soil bulk density, increased soil macroaggregates, and suppressed disease (Agegnehu et al 2015(Agegnehu et al , 2016aAkmal et al 2019;Cao et al 2018;Jien et al 2018;Khorram et al 2019;Liu et al 2019;McDonald et al 2019;Novak et al 2019;Sánchez-Monedero et al 2019). In Hawaii, several biochar and compost combinations significantly increased soil pH, reduced Al, Mn and Fe in the Oxisol, and for both the Oxisol and Ultisol, increased P, K and Ca, overcoming many plant limitations to growth (Berek et al 2018).…”

Many Hawaiian agricultural soils are acidic with low-nutrient retention; therefore, organic soil amendments are often used to improve soil properties and increase yields. Amendments can be incorporated for annual crops, but perennial orchards need surface application to avoid damaging surface roots. Pot trials compared responses to incorporated (IBC) or surface-applied (SBC) combination of hardwood biochar and chicken manure compost (4% v/v of each amendment) added to an Andisol and Oxisol. Soil pH was increased by 0.4–1.1 units in IBC and by 0.2–0.5 for SBC in the 0–10 cm soil layer. Both SBC and IBC increased soil total N, extractable P, Ca and Mg in the 0–10 cm soil layer. Soil pH, total C and extractable Ca were also higher in the 10–20 cm soil layer for IBC soil, indicating movement and/or leaching of amendments. Chinese cabbage biomass was 18–70% higher in the IBC and 14–47% higher in the SBC than that in the unamended soil, while papaya biomass was 23% and 19% higher in SBC and IBC, respectively. There was a greater response in the more acidic Andisol soil, with larger improvements in soil pH, plant nutrient uptake and root biomass than the Oxisol. Surface application was as effective in increasing plant growth as the incorporated amendment, providing evidence for farm scale assessment. Biochar and compost are recommended for use in tropical soils, and surface application may be beneficial to annual and perennial crops.

“…As to biochar, Trupiano et al [28] found that this amendment stimulated leaves number and total biomass of lettuce in soil poor in nutrients. In a comparison of the efficacy of peanut shell biochar and biochar-based compost on crown daisy and lettuce productivity, biochar had little effect on crop growth and mass yield [29]. In a pot experiment [30], the addition of rice-husk biochar to soil with and without fertilizers (a mixture of compost, liquid compost, and lake sediments) increased the final biomass, root biomass, plant height and leaves number of lettuce and Chinese cabbage.…”

Biochar, Vermicompost, and Compost as Soil Organic Amendments: Influence on Growth Parameters, Nitrate and Chlorophyll Content of Swiss Chard (Beta vulgaris L. var. cycla)

Soil addition with organic amendments is an issue that receives growing attention in the agricultural sector. However, the effects of such materials on plant growth and crop yield are highly variable in the literature. This study aims to evaluate the influence of soil addition with biochar (from vine pruning residues), vermicompost (from cattle manure), and three different composts (from olive pomace or cattle anaerobic digestate), on the quali-quantitative response of Swiss chard (Beta vulgaris L. var. cycla) grown in pots. The organic amendments were applied to the soil in two doses to provide 140 and 280 kg N ha−1, respectively. Two growth cycles were considered, and, at each leaf cut, plants were analyzed for growth parameters (height, fresh weight, leaf number, and leaf area) and qualitative characteristics (nitrogen, nitrate, and pigment leaf content). Swiss chard responded positively to organic amendment and, particularly when the soil was treated with compost from animal wastes, higher plant growth and pigment leaf content were observed. Nitrate leaf content was always well below the NO3− thresholds established by the European Commission Regulations. Biochar application did not show a positive effect on the quali-quantitative characteristics of Swiss chard, likely due to benefits that may be achieved over time.

“…BC contains key plant nutrients, although at a low level as demonstrated by several studies, and may have led to the lack of a complete plant nutrient profile in the soils to obtain a desirable increase in yields [223]. Multiple studies reported mixed results in terms of crop production [229,236] or described no effect [162,222,224,225]. Soil nutrient content and CEC were improved with BC amendment but were short-lived and resulted in comparable crop productivity compared to controls in studies with rice and wheat growing in wheat straw BC (350°C -550°C) [162], potatoes with green plantain peel-derived BC (450°C -500°C) [224], and tomatoes and maize with walnut shell-derived BC (900 °C) [225].…”

Biochar - A Panacea for Agriculture or Just Carbon?

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. As such, maintenance of soil quality, and reclamation of marginal soils, has become an increasingly important endeavor. Recently, there has been emerging interest in the use of biochar, a carbon rich, porous material thought to improve various aspects of soil performance. Biochar (BC) is produced through the thermochemical decomposition of organic matter at high temperature in an oxygen limited environment, in a process known as pyrolysis. Importantly, the source of organic material, or ‘feedstock,’ used in this process and different parameters of pyrolysis, especially temperature, determine the chemical and physical properties of biochar. Incorporation of BC impacts soil-water relations, tilth and nutrient status, pH, soil organic matter (SOM), and microbial activity. Soil amendment with BC has been shown to have an overall positive impact on soil health and crop productivity; however, initial soil properties need to be considered prior to the application of BC. There is an urgent need to understand the effects of long-term field application of BC and how it influences the soil microcosm. This knowledge will facilitate predictable enhancement of crop productivity and meaningful carbon sequestration.
