“…Biocharbased fertilizers (BF), as a new type of environmental protection fertilizer, have received attention in the elds of agriculture and environmental protection (Agarwal et al 2022). The BFs are made by mixing biochar with organic or inorganic fertilizers which can be used as a slow-release nutrient carrier (Gao et al 2022). The BF not only confers the advantage of soil improvement but also continuously supplies nutrients in combination with the fertilizer requirements of crops, thereby reducing nutrient losses and achieving the dual functions of slow release and carbon xation (Guo et al 2021).…”

In spite of decades of political commitments, research, and applications of innovations for reducing climate change's causes and catastrophic impacts, the global CO2 emissions have continued to rise. Achieving more stringent reduction targets requires rapid activities towards carbon neutrality in many ways to accelerate the transition to equitable, sustainable, livable, post-fossil carbon societies. Conventional agriculture, is responsible for 14% of global annual greenhouse gas (GHG) emissions and is causing an additional 17% through land use changes, mostly in developing countries. This is due to GHG emissions from its food production activities that include the farming activities, food transportation to food processing facilities, distribution, marketing, food usage, and food waste. The negative impacts of current agricultural practices underscore the urgency to transition to holistic, regenerative agricultural practices where negative carbon emission technologies such as the usage of biochar and other approaches are used to dramatically decrease the GHG emissions as well as to make the transition to circular economies via food chain, carbon neutrality. It is unfortunate that at this time, carbon sequestration progress and implementation of circular economy principle is well documented and to be practically achievable, the progress needs to be quantitatively measured. The authors of this paper, proposed a system of indicators for measuring progress toward carbon neutrality in agriculture based on circular economy principles. To accelerate the needed transition to regenerative agriculture, the extensive production and usage of biochar is essential.

“…Following Arya et al (2001), total soluble sugar and Vitamin C were measured by using a spectrophotometer. The calorific value was measured by using the oxygen bomb of the automatic calorimeter (ZDHW-5000 type) (Darling, 1976;Gao et al, 2022). Crude fat was measured by using the Soxhlet extraction technique and a fat extractor (JC-ZF-04) (Felton et al, 2009).…”

Global primates are endangered, and thus it is important to know the determinants of primate population dynamics. It is widely reported that food plant diversity and nutrients are key determinants of many primate population dynamics. However, it remains unknown whether this can be applied to explain the population dynamics of Hainan gibbon (Nomascus hainanus), the world’s rarest primate. Recently, two individuals moved out from one family group (group C) and went across more than 9 km to form a new family group (group E), thus providing a perfect chance to quantify whether food plant diversity and nutrients can determine Hainan gibbon’s formation of the new family group. Here, we used a plot survey to compare the differences in food plant diversity (species richness and abundance) and nine leaf nutrient traits (leaf water content, total soluble sugar, vitamin C, calorific value, crude fat, crude protein, crude fiber, Zn, and Fe) between group C and group E. We found that plant diversity in group E was indeed higher (1.35–1.41 times) than that in group C. Moreover, in both groups C and E, food plant diversity within the home range was also higher (1.4–1.6 times) than that out of the home range. However, both cases could not be witnessed for all leaf nutrient traits. Results of principal component analysis revealed that food plant species between groups C and E were all significantly separated by food plant diversity but not leaf nutrient traits. Food plant species within and out of the home range of both groups C and E could also be significantly separated by food plant diversity, but not for all leaf nutrient traits. In conclusion, food plant diversity was one key determinant of the formation of a new family group of Hainan gibbons. Choosing high food plant diversity was also one key motivation for Hainan gibbons to select their home range.

Biochar-Based Fertilizer Enhances the Production Capacity and Economic Benefit of Open-Field Eggplant in the Karst Region of Southwest China

Biochar as an amendment has been widely applied to enhance crop productivity and improve soil quality. However, the effect of biochar-based fertilizer (BF) on the production capacity and economic benefits of open-field eggplant in the karst region remains unclear. A field experiment was carried out in the karst region of Southwest China from 2020 to 2021 to study the ameliorative roles of different application rates (1875, 2250, 2625, and 3000 kg ha−1) of BF on the fresh yield, quality, fertilizer utilization, and economic benefits of fresh eggplant. The results show that BF increased the yield of fresh eggplant by 3.65–13.76% (2020) and 23.40–49.04% (2021) compared to the traditional fertilization practice (TFP). The application of BF reduced the nitrate content and increased the vitamin C (VC) and soluble sugar content of the fruits, which is beneficial for improving the quality of eggplant fruits. Meanwhile, the application of BF not only increased the nutrient uptake of the eggplant but also significantly improved the fertilizer utilization rates, especially the agronomic efficiency (AE) and recovery efficiency (RE). Moreover, BF could also significantly increase the output value and net income of fresh eggplant, which can help farmers increase their income. In conclusion, a BF application rate of 2544–2625 kg ha−1 could be used to improve the yield, fertilizer efficiency, and economic benefits of open-field eggplant and is recommended for managing agricultural production in the karst region of Southwest China.
