To examine the mechanisms of organic carbon transformation and sequestration by biochar in citrus orchard soil, a 100-day mineralization test was conducted using soil from 5-year-old forest. Calcium-modified peel (OBC-Ca) applied at rates 0%, 1%, 2%, 4%. The results indicated that different percentages OBC-Ca significantly influenced processes orchards. Specifically, cumulative notably reduced 8.68% 17.00% with application 2% 4% OBC-Ca, respectively, compared to control group. Random forest analysis revealed microbial biomass (MBC), readily oxidizable (ROC), dissolved (DOC) were critical indicators for predicting carbon. MBC ROC found inhibit mineralization, while DOC promoted it. As proportion applications increased, rose 2.63% 10.46%, increased 16.41% 108.59%, 0.48% 11.67%. Correlation demonstrated significant negative correlation between rate enzyme activity, sucrase content increasing 216.42% 393.44% control. calcium-modified effectively reduces dioxide emissions soils, yielding most favorable outcomes enhancing sinks, thereby positively impacting potential soil.

To demonstrate the effects of combined application biochar and different types nitrogen fertilizers on growth plant roots purple soil properties such as nutrients, carbon content respiration, a 206-day greenhouse pot experiment with rapeseed was conducted. Three fertilizer were used: urea (UR), controlled-release (RU), mixture 60% 40% (40% RU), added at mass fractions 0% (C0), 2% (C1) 4% (C2), control treatment (CK) without biochar. The results showed that significantly improved nutrient status, best effect observed when 40%RU co-applied addition increased total organic (TOC) particulate (POC). Soil respiration increasing application, combination RU reduction in emissions compared to UR treatments. number root tips (NT), forks (NF) crossings (NC) biochar, more beneficial for development than UR. Considering improvement nutrition, content, reduced emissions, enhanced development, co-application is recommended large-scale cultivation hilly southwest China.

Abstract Soil organic carbon (SOC) is the most important pool in terrestrial ecosystem. However, temporal variations paddy SOC under a temperate continental monsoon climate are poorly understood. Here, we demonstrate that significant occur meadow soil (MS), black (BS) and planosol (PS) soils. Several samples were collected from different regions where rice was cultivated for 1, 6, 10, 23 40 years MS samples; 20 35 BS 5, 15 25 PS samples. The total (TOC) content humus (HOC) found to increase as cultivation duration increased, while mineralizable (MOC) carbohydrate (COC) exhibited opposite trend. relationships between relative accumulation (Y) three types time (X) consistent with following models: Y TOC = 0.9973X 0.0245 , HOC 0.9936X 0.0457 MOC 1.023X −0.073 COC 1.040X −0.059 describing variation various forms of soils climate. results this study provide reference management fertilization management.
