Current agricultural practices are increasingly favoring the biochar application to sequester carbon, enhance crop growth, and mitigate various environmental pollutants resulting from nitrogen (N) loss. However, since biochar's characteristics can vary depending on pyrolysis conditions, it is essential determine optimal standard, as they have different effects soil health. In this study, we categorized rice husk biochars basis their pH levels investigated role of each in reducing ammonia...

Abstract An optimal use of organic composts derived from animal and food wastes could provide an opportunity to achieve both sustainable crop production soil quality, a lot research has provided the evidence. The nitrogen efficiencies (NUEs) is definition evaluate interaction between (N), and, due this reason, widely used in agriculture. current work tried NUEs as indicator N acquisition capacity physiological responses rice grown under varying levels. To do this, we employed different types...

Abstract The need for organic soil amendments is increasing in the Republic of Korea against backdrop increased acidification and nutrient losses. pyrolysis biomass produces biochar which not only increases productivity but also provides environmental benefits through carbon sequestration. portion brewer’s spent grain (BSG) recycled by far less than amount generated, can help to reverse this trend turning BSG waste into a valuable amendment. current study, therefore, evaluated effects (BB...

Abstract We examined the possibility of an environment‐friendly slow‐release fertilizer (SRF) made biochar impregnated by anaerobically digested slurry. The materials were produced from three types feedstocks (orange peel, residual wood, water‐treatment sludge) at different temperatures 300°C, 500°C, and 700°C via pyrolysis. release behaviors water‐soluble K + , Ca 2+ Mg similar for all biochars commercial SRF used. water‐retention capacity was greatly improved mixing biochar‐SRF with soil....

Abstract This study determined the fertilizer potentials of dehydrated food waste powder (DFWP) and spent coffee grounds (SCGs) through assessing their effects on yield, antioxidant activities, mineral proximate compositions leaf lettuce Japanese hogfennel efficiencies to inorganic fertilizers (N-P 2 O 5 -K O, NPK). In this study, both organic amendments were applied at rates that supplied half, double recommended nitrogen (N) requirements (15 Mg N/ha) (10 established in Daejeon, South...

We examined the physico-chemical properties of biochar produced from orange peel, residual wood, and water treatment sludge at different pyrolytic temperatures 300 to 700˚C. In peel (OPB) wood (RWB), pH carbon content tended increase with increasing tem- perature were higher than those in (WSB). The electrical conductivity OPB was highest, while specific surface area RWB highest among three types biochar. relatively high any Any displayed by scanning- electron-micrographs revealed many...

Abstract Xylem sap plays a major role in long‐distance transport of water, nutrients, and metabolites. However, there is little information on the behavior metabolites mineral‐deficient xylem sap. For this reason, time‐dependent changes selected (amino acids, organic soluble sugars) from tomato response to nitrogen (N), phosphorus (P), or potassium (K)‐deficient condition were investigated. Tomato plants ( Solanum lycopersicum L.) grown hydroponically liquid culture under three different...

The use of nitrogen fertilizers to enhance crop growth tends increase every year. In addition, as eco-friendly agriculture is emphasized, organic are preferred over inorganic fertilizers. However, since most in South Korea imported ingredients, an alternative ingredients needed. Biochar way recycle various biomass and has a high pH carbon contents. objective this study was evaluate the effect individual co-application on ammonia (NH3) volatilization soil quality. Organic used were divided...

Abstract Straw incorporation is strongly recommended in rice paddy to improve soil quality and mitigate atmospheric carbon dioxide (CO 2 ), via increasing organic (SOC) stock. However, straw application significantly increased methane (CH 4 ) emission during cultivation, then its area was not expanded effectively. To find the reasonable management practice which can reduce CH without productivity damage, effect of season method on investigated at six different textured fields South Korea for...

Despite the widespread use of food waste compost as a soil organic amendment, there is limited information on how it affects composition microbial community well its relationship environmental factors. This study investigated effects microbial-community by using FAME analysis. It was established that application composts in water saturated paddy and unsaturated upland soils increased pH levels, electrical conductivity (EC) values, total carbon (TC), ESP contents. also phospholipid fatty acid...

Abstract Ammonium ions (NH 4 + ) are commonly found in contaminated water and a contributing factor to eutrophication. Carbonized rice husk, derived from various biomass sources, possesses porous structure, its characteristics influenced by the feedstock pyrolysis conditions. Hence, this study aimed investigate applicability of carbonized husk as an absorbent for NH removal. The adsorption kinetics were analyzed using Pseudo-first-order Pseudo-second-order models, while assessed Langmuir...

Methane emissions from flooded rice paddies are a major source of atmospheric methane and represent significant greenhouse gas with high climate-forcing potential due to anthropogenic activities globally. For sustainable agriculture, it is necessary find effective methods for mitigating without reducing crop productivity. We investigated mechanisms reduce during cultivation by applying straw, husk biochar, humic acid, acid–iron complex, assessing gases yield over single season. The results...

The amount of vegetable waste (VW) has increased, and demand for good quality organic soil amendment is high. For these reasons, successive composting technique was tried to examine the possibility increasing nitrogen contents in compost. Collected VW initially composted after mixing with either sawdust (SD) or cocopeat (CP) at different ratios (30–50% SD CP). After finishing first cycle, finished compost mixed fresh various (10–30% VW) second cycle composting. Temperature, pH, electrical...

NH3 emitted into the atmosphere undergoes intricate chemical reactions to form fine particulate matter PM2.5. Nitrogen fertilizers are one of major sources gaseous ammonia. Recently, research using biochar lessen emissions from agricultural land has taken center stage and several studies have been executed in that regard. However, biochar’s capacity reduce applied nitrogen is affected by both soil properties. While effects properties on volatilizations widely studied, data concerning still...

Abstract As interest in sustainable agricultural land management continues to grow, there is a need for advanced techniques that enable easy and rapid quantification of soil characteristics. Soil organic matter (SOM) critical factor determining health. Unfortunately, contemporary SOM content analysis are laborious, time consuming, resource intensive. In response this challenge, our study has developed statistical model forecasting the using color indices machine learning algorithms. Color...

We analyzed the contents of 38 primary metabolites and 9 minerals in leaves roots bell pepper (Capsicum annuum L. var. angulosum) to study metabolic responses deficiency nitrogen, phosphorus, potassium, calcium, or magnesium. Induced deficiencies individual cations reduced abundance other both roots. Each nutrient-deficient condition was clearly grouped by principal component analysis, which also showed that under cation-deficiency treatments were separated from those non-cation-deficiency...
