Phosphate Solubilizing

The inoculation of beneficial microorganisms to improve plant growth and soil properties is a promising strategy in the soil amendment. However, the effects of co-inoculation with phosphate-solubilizing bacteria (PSB) and N2-fixing bacteria (NFB) on the soil properties of typical C-deficient soil remain unclear. Based on a controlled experiment and a pot experiment, we examined the effects of PSB (M: Bacillus megaterium and F: Pseudomonas fluorescens), NFB (C: Azotobacter chroococcum and B: Azospirillum brasilence), and combined PSB and NFB treatments on C, N, P availability, and enzyme activities in sterilized soil, as well as the growth of Cyclocarya Paliurus seedlings grow in unsterilized soil. During a 60-day culture, prominent increases in soil inorganic N and available P contents were detected after bacteria additions. Three patterns were observed for different additions according to the dynamic bacterial growth. Synergistic effects between NFB and PSB were obvious, co-inoculations with NFB enhanced the accumulation of available P. However, decreases in soil available P and N were observed on the 60th day, which was induced by the decreases in bacterial quantities under C deficiency. Besides, co-inoculations with PSB and NFB resulted in greater performance in plant growth promotion. Aimed at amending soil with a C supply shortage, combined PSB and NFB treatments are more appropriate for practical fertilization at intervals of 30–45 days. The results demonstrate that co-inoculations could have synergistic interactions during culture and application, which may help with understanding the possible mechanism of soil amendment driven by microorganisms under C deficiency, thereby providing an alternative option for amending such soil.

Drought is one of the major threats to global food security. Biochar use in agriculture has received much attention and improving it through chemical modification offers a potential approach for enhancing crop productivity. There is still limited knowledge on how acidified biochar influences soil properties, and consequently its influences on the agricultural productivity of drought stressed plants. The water use efficiency (I-WUE) of drought stressed faba beans was investigated through the effects of acidified biochar (ACBio) (a 3:100 (w:w) combination of citric acid and biochar) on soil properties, growth, productivity, nutrient uptake, water productivity (WP), and irrigation. Two field experiments (2016/2017 and 2017/2018) were conducted in saline soil (ECe, 7.2 dS m−1) on faba been plants grown under three irrigation regimes (i.e., 100, 80, and 60% of crop evapotranspiration (ETc)) combined with three levels of ACBio (0, 5, and 10 t ha−1). Plants exposed to water stress presented a significant decrease in plant height, dry matter, leave area, chlorophyll content (SPAD), the quantum efficiency of photosystem II (Fv/Fm, Fv/F0, and PI), water status (membrane stability index and relative water content), and seed yield. Acidified biochar soil incorporation improved soil properties (chemical and physical), plant growth, physiological responses, WP, I-WUE, and contents of N, P, K, and Ca. Results revealed that the application of ACBio at 10 t ha−1 and 5 t ha−1 significantly increased seed yield by 38.7 and 25.8%, respectively, compared to the control. Therefore, ACBio incorporation may find application in the future as a potential soil amendment for improving growth and productivity of faba bean plants under deficit irrigation.

The Effect of the Mount Agung Volcanic Ash and Compost on Soil Properties and Yield of Tunggak Nuts (Vigna unguiculata (L.) Walp). The purpose of this study was to determine the effect of giving volcanic ash and compost as a soil amendment. The design used was a factorial randomized block design. The volcanic ash factor consisted of 3 levels: A0 = no volcanic ash, A1 = 15% volcanic ash and A2 = 30% volcanic ash. The compost factor consisted of 3 levels: K0 = without compost, K1 = 10 tons of compost ha-1, and K2 = 20 tons of compost ha-1. The combination treatments was repeated 3 times so that there were 27 observation units. Several parameters of soil properties and yield of tunggak nuts were studied to determine the effect of volcanic ash and compost as soil amendments. The results showed that the interaction between the treatment of volcanic ash and compost on the soil and plants was not significant, while the single treatment of compost had a significant effect on the growth and yield of tunggak nuts. The treatment of volcanic ash has not shown a significant effect, both on soil and on plant growth and yield.

Severe Erosion

Erosion leads to substantial loss of soil productivity. To abate such decline, amendments such as manure or fertilizer have been successfully employed. However, the longevities of erosion and soil amendment legacy effects are not well quantified. In 1957, a Dark Brown Chernozem soil at Lethbridge, AB, was land-levelled, creating three degrees of topsoil removal or erosion: noneroded, moderate erosion, or severe erosion. Two amendment studies (1980–1985 and 1987–1991) were superimposed on the erosion treatments. Both studies were cropped to spring wheat (Triticum aestivum L.) from 1993–2010 to examine legacy effects of erosion and soil amendments on wheat yield and soil properties. Without amendment, mean wheat yield under moderate erosion was 40% of the noneroded treatment, whereas severe erosion was 34% of the noneroded treatment, 36–42 yr (1993–1999) after erosion. Under moderate or severe erosion, the restorative power of manure diminished substantially in the first 10–15 yr following cessation of addition, but then levelled off resulting in wheat yields up to 35% higher than equivalent nonamended treatments. Legacy effects of erosion (54 yr) and amendment (27–31 yr) on soil organic carbon and total nitrogen were also observed.

The article presents the findings of a field experiment investigating the effectiveness of biochar and plant biomass ash when used as a soil fertiliser in the cultivation of basket willow (Salix viminalis L.). The purpose of the study was to determine the optimal dose of fertiliser to enable a maximum increase in the crop yield and enhancement of the chemical properties of the soil. In the course of the two-year experiment, the increase in basket willow yield was in the range of 6%–49%. The highest dry matter yield from the plants, at the end of both the first and the second year of the experiment, was obtained in the plots where the soil was amended with biochar alone (11.5 t ha−1), a combination of biochar and ash (respectively 11.5 and 1.5 t ha−1) and ash added at the rate of 1.5 t ha−1. The yield was reduced when the soil was amended with ash added at the rates of 3.0 t ha−1 and 4.5 t ha−1 or with the latter doses of ash combined with biochar. The results indicated that too high a concentration of ash (rate of 3.0 t ha−1 or higher for basket willow) have negative effects on plant growth and may represent a limiting factor. The study suggests that biochar is a better soil amendment than ash, because biochar application gave the highest improvement in the soil properties and plant growth. It was found that the addition of biochar, biomass ash or combinations of the two materials applied in suitable doses may be a good soil amendment.. In particular in soils which are severely damaged and require restoration, this fertilization may have a noticeable effect on soil properties and plant growth.

The Impact

Biochar, a carbon-rich material produced by the pyrolysis of organic residues, is frequently used as a soil amendment to enhance soil fertility and improve soil properties in tropical climates. However, in temperate agriculture, the impact of biochar on soil and plant productivity remains uncertain. The objective of this review is to give an overview of the challenges and opportunities of using biochar as an amendment in temperate soils. Among the various challenges, the type of feedstock and the conditions during pyrolysis produces biochars with different chemical and physical properties, resulting in contrasting effects on soils and crops. Furthermore, biochar aging, biochar application rates and its co-application with mineral fertilizer and/or organic amendments add further complexity to our understanding of the soil-amendment-plant continuum. Although its benefits on crop yield are not yet well demonstrated under field studies, other agronomic benefits of biochar in temperate agriculture have been documented. In this review, we proposed a broader view of biochar as a temperate soil amendment, moving beyond our current focus on crop productivity, and instead target its capacity to improve soil properties. We explored biochar’s benefits in remediating low productive agricultural lands, and its environmental benefits through long-term carbon sequestration and reduced nutrient leaching while curtailing our reliance on fertilizer input. We also discussed the persistence of beneficial impacts of biochar in temperate field conditions. We concluded biochar displays great prospective to improve soil health and its productivity, enhance plant stress resilience, mitigate greenhouse gas emissions and restore degraded soils in temperate agriculture.
