Organic amendments are widely used to enhance soil fertility and nutrient cycling in greenhouse cultivation, but their effectiveness can vary depending on origin composition. This study investigated the impact of four organic materials (rice husk, coconut coir, biochar, sheep manure) enzyme activities two tomato soils. The distribution nutrients was analyzed under controlled conditions during a pot experiment. addition amendments, regardless source, significantly altered microbial resource allocation, reducing carbon limitation while increasing nitrogen demand. effect pools largely determined by chemical composition amendments. In clayey soils, biochar rice husk additions most effectively promoted related carbon, nitrogen, phosphorus acquisition. Under sandy conditions, manure increased acquisition enzymes, enhanced enzymes. Biochar emerged as particularly effective amendment, enhancing sequestration across different types. specifically, content carboxyl C, aromatic O-alkyl played crucial role influencing limitations. mean C:N:P ratios for CK, T1, T2, T3, T4 treatments were 1:1.375:0.625, 1:1.244:0.662, 1:0.839:0.610, 1:1.161:0.689, 1:1.038:0.549, respectively. 1:1.117:0.698, 1:1.18:0.75, 1:1.096:0.731, 1:1.217:0.689, 1:1.06:0.669, These findings suggest that improve retention activities, effects influenced both texture. research enhances our understanding transformations, aids optimizing application improved management cultivation.

Air quality is an essential factor for human health and ecosystem balance, but in regions like Petroșani Mountain Depression, air pollution continues to be a significant challenge. This area, marked by decades of coal mining, confronted with high concentrations pollutants, influenced activities the specific geography climate. study aims compare instrumental measurements snow sample analysis, as sustainable alternative method. Specifically, it examines spatiotemporal distribution evolution utilizing long-term monitoring data extensive sampling network (42 points) both snow, provide thorough understanding dynamics area. The experimental part this focused on determining VOCs PM air, dissolved ions (sulfate, calcium, magnesium) suspended solids snow. results highlight correlations between sources atmospheric mountain depressions, while also analyzing efficiency instruments used collection. emphasizes that, although methods precise detailed measurements, their implementation isolated presents challenges. Therefore, approaches such analysis can represent more efficient option these regions.
