Biochar for Improving crop Production in Nepal
نویسندگان
چکیده
Improving soil fertility and crop productivity is crucial to reduce food insecurity poverty in Nepal. Biochar as a amendment has been found effective increasing production. Here, we reviewed various biochar studies carried out Nepal by different organizations assessed future potential of an amendment. In this review, have included the pretreated (enriched) with nutrient or added separately soil. We that good quality could be produced using novel flame curtain metal pit “Kontik” kiln slow pyrolysis technology. from Kontiki having high pH (9.8), organic carbon (OC, 72%), surface area (215 m2g-1) cation exchange capacity (CEC, 72 cmol kg-1). Further, application improved chemical properties (pH, OC, CEC, base cations) availability such available phosphorous (P) potassium (K). Similarly, addition increased yield significantly compared non-biochar plots. Higher was achieved when enriched charged cattle urine. Thus, study, suggest should prioritized government programs scale up increase its use at farm level. SAARC J. Agric., 21(1): 227-238 (2023)

Improving water use in crop production.
Globally, agriculture accounts for 80-90% of all freshwater used by humans, and most of that is in crop production. In many areas, this water use is unsustainable; water supplies are also under pressure from other users and are being affected by climate change. Much effort is being made to reduce water use by crops and produce 'more crop per drop'. This paper examines water use by crops, taking...
متن کاملLarge-Scale Biochar Production from Crop Residue: A New Idea and the Biogas-Energy Pyrolysis System
Biochar is an effective means to withdraw carbon dioxide (CO2) from the atmosphere and consequently influence the trend of global climate change. However, there still are substantial knowledge gaps for this idea to be applicable. One big question is how to produce biochar from biomass on a large scale. Our idea is to use biogas produced from agricultural wastes as thermal energy for biochar pro...
متن کاملBiochar: Effects on Crop Productivity and Soil Properties
World food security is under challenge to a great extent due to effects of climate change, continued population growth and resource-depleting practices on agriculture (IAASTD, 2009). Presently poor farmers use either organic manure or inorganic fertilizers (Mando et al., 2005; Topoliantz et al., 2005) for maintaining soil fertility as they cannot afford to apply fertilizers as a nutrient source...
متن کاملManaging Phosphorus for Crop Production
Phosphorus is a macronutrient that plays a number of important roles in plants. It is a component of nucleic acids, so it plays a vital role in plant reproduction, of which grain production is an important result. It is also critical in biological energy transfer processes that are vital for life and growth. Adequate phosphorus results in higher grain production, improved crop quality, greater ...
