“…Therefore, considering the source of biochar, synthesis conditions, type of soil, and even the type of the crop are essential factors that should be collectively considered for achieving better sustainable agricultural production without posing undesirable physical or biological alternations to utilized agroecosystems [2,11]. Biochar effect is soil type-dependent; for example, for decreasing sandy soil bulk density, at least 1% of biochar addition is required, whereas it was at least 5% for sand-loam soil [12,13]. Indeed, it is frequently reported that the application of biochar to soil for ameliorating its properties and enhancing crop productivity is more successful with well-weathered soils (degraded), low fertility soils, and acidic soils, than with fertile healthy soils [11,[14][15][16].…”

“…At the level of the microbial community, biochar was confirmed to alter the balance between bacteria and fungi in the soil, but in a contradictory manner. There is no tangible answer to whether biochar enhances or diminishes soil microorganisms, as both effects were reported with biochar-added soil [13,21,23].…”

“…It is one of the most significant vegetable crops in Egypt for local utilization and exportation [31,32]. Globally, Egypt is the fifth top country in tomato production where the top four are: China (64,768,158 tons), India (20,573,000 tons), Turkey (13,204,015 tons), and USA (12,227,402 tons). The total harvested area in Egypt is 170,862 hectares with a production amount of 6,731,220 tons (4% of global contribution in tomato production).…”

Effect of Biochar Application to Fertile Soil on Tomato Crop Production under Saline Irrigation Regime

Biochar application is a promising sustainable strategy for enhancing soil properties thus crop production. However, biochar application to soil certainly alters its biological and physical properties, and could require extra costs. Therefore, biochar suitability to agroecosystems must be proactively estimated. The advantage of biochar addition to poor fertile or weathered soils has been well studies, however, its feasibility to fertile soil under low quality (saline) irrigation water was not frequently studied. Consequently, this work investigates the hypothesis of whether the application of biochar at a rate of 4.8 tons/ha to fertile soil (Nile Valley, Giza, Egypt) would ameliorate the negative effects of saline irrigation regime (3000 ppm) on tomato crop and soil. The results of two seasons experiments showed that saline irrigation significantly reduced tomato crop yield by an average reduction ratio of 51%, and biochar addition could not compensate such reduction. Furthermore, biochar did not reduce accumulated Na+ in fruits or roots. Tomato fruits produced from biochar-added soil were lower in TSS levels (41.7% reduction ratio) yet larger in diameter by approximately 1.5-fold increase. Interestingly, biochar addition into soil greatly promotes the length of stem-borne lateral roots and elevates the expression of LeNR (encodes nitrate reductase enzyme) in leaves yet under fresh irrigation regime. For soil properties, biochar application enhanced the soil properties under either saline or fresh water irrigation conditions. Collectively, it is assumed that biochar application to fertile soil in Nile Valley of Egypt could not alleviate tomato fruits yield reduction affected by applied saline irrigation regime.

The impact of climate change is the biggest challenge for the agricultural sector, especially the food crops sub-sector. The research was conducted in Jembrana Bali. The aim was to obtain new high yielding varieties of rice and location-specific adaptive planting methods. The research time April - August 2021. Used a factorial randomized block design. The first factor consists of the type of variety (V) and the second factor is the method of planting (T). The type of variety (V) consists of 3 levels, namely V1=Bioni 63; V2= Inpari 32; and V3 = Inpari 30, while the method of planting (T) consists of 2 levels, namely T1 = direct seed planting, and T2 = transplanting. Data were analyzed using analysis of variance and further test with LSD 5%. The results showed that the treatment of varieties and planting methods had no significant effect on the diversity of carnivorous arthropods. Four types of carnivorous arthropods were found, namely odonata, araneae, coccinellidae, and paederinae with a low species diversity index of 0.4985; 0.5210; 0.5172; 0.4976; 0.5205, and 0.5057 in V1T1; V1T2; V2T1; V2T2; V3T1, and V3T2. Dominant herbivorous arthropods were Scirpophaga incertulas Walker, Cnaphalocrocis medinalis, Nilaparvata lugens Stal, and Leptocorisa oratorius. The highest yield was shown in V1T2 at 9.44 tons/ha. It was concluded that the new high yielding varieties of rice and location-specific adaptive planting methods were Bioni 63 Agritan transplanting. The use of the new high-yielding variety Bioni 63 Agritan also contributed to the reduction in the use of chemical pesticides, with data supporting low yellow rice stem borer attack.The relationship between research results and sustainable agriculture is supports sustainable agriculture.

“…Biochar stored in the soil can also trap carbon, as well as lower greenhouse gas emissions in the field such as carbon dioxide, methane, and nitric oxide, thereby decreasing global warming (9)(10)(11). The incorporation of biochar into the soil environment would undoubtedly impact the environmental behavior of numerous contaminants in the soil, and thus the fate of pollutants in the environment (12). Biochar has been proven to have tremendous promise in the prevention and restoration of organic pollution in soil and aquatic environments.…”

Biochar is a porous carbon-rich substance generated by anoxic pyrolysis of biomass. Biochar has a high adsorption capacity for organic contaminants in water and soil environmental media due to its large specific surface area and surface physical and chemical characteristics. The effects of biochar application on the adsorption-desorption behavior and bioavailability of pesticides in soil are illustrated in this paper; biochar can strongly adsorb pesticides in soil due to its loose and porous properties, large specific surface area and surface energy, and highly aromatic structure. Residual pesticide pollutants are reduced, as is desorption hysteresis, which reduces pesticide desorption. Furthermore, the use of biochar reduced the absorption and efficacy of pesticides in soil. At the same time, it describes the present gaps in research on the influence of biochar on pesticide migration mechanisms and its application in pesticide pollution control, and it identifies the major scientific issues that need to be addressed. Finally, the potential application of biochar in pesticide pollution management is discussed.
