“…Many recent studies have reported increased crop yield (Subedi et al, 2016a;Vaccari et al, 2011;Usman et al, 2016;Kammann et al, 2012;Baronti et al, 2010;Uzoma et al, 2011;Houben et al, 2013;Genesio et al, 2015;Cornelissen et al, 2013;De La Rosa et al, 2014;Fox et al, 2014;Gregory et al, 2014;Lin et al, 2015;Schmidt et al, 2015;Butnan et al, 2015;Laghari et al, 2015;Mandal et al, 2016). Others have reported no yield effect (Cornelissen et al, 2013;Uzoma et al, 2011;Nelissen et al, 2015;Subedi et al, 2016aSubedi et al, , 2016bNielsen et al, 2014;Tammeorg et al, 2014;Suddick and Six, 2013;Schmidt et al, 2014;Bass et al, 2016).…”

Crop response to soils amended with biochar: expected benefits and unintended risks

et al. 2017

Biochar (BC) from biomass waste pyrolysis has been widely studied due to its ability to increase carbon sequestration, reduce greenhouse gas emissions, and enhance both crop growth and soil quality. This review summarises the current knowledge of BC production, characterisation, and types, with a focus on its positive effects on crop yield and soil properties vs the unintended risks associated with these effects. Biochar-amended soils enhance crop growth and yield via several mechanisms: expanded plant nutrient and water availability through increased use efficiencies, improved soil quality, and suppression of soil and plant diseases. Yield response to BC has been shown to be more evident in acidic and sandy soils than in alkaline and fine-textured soils. Biochar composition and properties vary considerably with feedstock and pyrolysis conditions so much that its concentrations of toxic compounds and heavy metals can negatively impact crop and soil health. Consequently, more small-scale and greenhouse-sited studies are in process to investigate the role of BC/soil/crop types on crop growth, and the mechanisms by which they influence crop yield. Similarly, a need exists for long-term, field-scale studies on the effects (beneficial and harmful) of BC amendment on soil health and crop yields, so that production guidelines and quality standards may be developed for BCs derived from a range of feedstocks.

“…Liu et al [33] reviewed published data from 59 pot experiments and 57 field experiments, concluding that crop productivity was increased by 11 % on average. Uzoma et al [34] reported the effects of biochar produced from cow manure on corn yield, nutrient uptake, and physicochemical properties when used on a sandy soil. They found that applying 15 or 20 t ha −1 of biochar significantly increased corn grain yield by 150 or 88 %, respectively, when compare to an untreated control.…”

Soil Health, Crop Productivity, Microbial Transport, and Mine Spoil Response to Biochars

et al. 2016

Biochars vary widely in pH, surface area, nutrient concentration, porosity, and metal binding capacity due to the assortment of feedstock materials and thermal conversion conditions under which it is formed. The wide variety of chemical and physical characteristics have resulted in biochar being used as an amendment to rebuild soil health, improve crop yields, increase soil water storage, and restore soils/spoils impacted by mining. Meta-analysis of the biochar literature has shown mixed results when using biochar as a soil amendment to improve crop productivity. For example, in one meta-analysis, biochar increased crop yield by approximately 10 %, while in another, approximately 50 % of the studies reported minimal to no crop yield increases. In spite of the mixed crop yield reports, biochars have properties that can improve soil health characteristics, by increasing carbon (C) sequestration and nutrient and water retention. Biochars also have the ability to bind enteric microbes and enhance metal binding in soils impacted by mining. In this review, we present examples of both effective and ineffective uses of biochar to improve soil health for agricultural functions and reclamation of degraded mine spoils. Biochars are expensive to manufacture and cannot be purged from soil after application, so for efficient use, they should be targeted for specific uses in agricultural and environmental sectors. Thus, we introduce the designer biochar concept as an alternate paradigm stating that biochars should be designed with properties that are tailored to specific soil deficiencies or problems. We then demonstrate how careful selection of biochars can increase their effectiveness as a soil amendment.

Results of the present study revealed that the application of all the studied treatments decreased soil bulk density, hydraulic conductivity, pH, EC, soluble Na, SAR and ESP values, while increased cation exchange capacity, organic matter content, total N as well as available amounts of P, K, Fe, Mn, Zn and Cu in soil.Data also indicated that all the treatments significantly increased the grain yields of wheat and corn plants and the treatment (20 kg humic acids/fed.) was the best one. The rate of increment over the control due to such treatment reached 39.49 and 37.68 % for wheat and corn grain yields, respectively. Also, macro and micronutrient concentrations of such grains were significantly increased by increasing the application rates of the applied conditioners.Based on results of the current study, it can be concluded that using biochar and humic acids as organic conditioners is helpful to improve soil properties, compensate the deficiency of nutrients in soil and have significant effects on the productivity of wheat and corn plants. These materials are easily producible, biodegradable, less expensive, cause no environmental hazards to human health and will be ecologically safe and culturally more acceptable among farmers. So, it can be recommended to use such materials as soil conditioners under salt affected soil conditions.
