Weed Growth

The growth of weeds among agricultural crops is a pest that can decrease agricultural production by 47-87%. The aims of this research is to compare organic and an organic fertilizer and compare mechanical and chemical weed and pest control. This research employed a mixed-method, observation, in-depth interviews, and life cycle assessment. The greenhouse gas emissions were released are organic fertilizer 1,87 x 10-3 kg CO2 eq/ha and an organic fertilizer 15 x 101 kg CO2 eq/ha. Thereafter greenhouse gas emissions were released from mechanical control 1,87 x 10-3 kg CO2 eq/ha and chemical control 4,4 x 101 kg CO2 eq/ha. The totally of greenhouse gas emissions was released from dryland paddy farming in management phase is 19,4 x 101 kg CO2 eq/ha. Organic fertilizer more friendly than an organic fertilizer and mechanical control more friendly than chemical control. Mechanical control by farmers must be modified for the increase of effectiveness. The post-mechanical control should be those containing fruit and seed must be burned, meaning there will be not a longer any weed growth potential. Therefore, this mechanism will be able to realize potential production and sustainable dryland paddy farming.

Greenhouse Gas Intensity

The sustainability of intensification of rice production is a prime concern for China. Application of organic amendments, changes in crop rotation system, ducklings’ introduction, and construction of vegetated drainage ditches are some of the original management strategies to mitigate environmental pollution from paddy fields. Although these practices affect the rice culturing system through different mechanisms, there is limited investigation on their effectiveness on nutrient pollution alleviation. Therefore, a field study was carried out with the assessment of soil physico-chemical properties, greenhouse gas emissions, nitrogen removal efficiency, grain yield, and economic benefits by comparing the eco-rice culturing system (ER) to the local single rice cultivation system (CK). Results showed that the ER system can significantly improve soil fertility by increasing the pH in acidic soil, organic matter, total nitrogen (TN), and available potassium (K) content by 5.2%, 25.7%, 19.1%, and 19.4% in relation to CK, respectively. Meanwhile, about 10% of the total fertilizer N was removed from the harvesting of the plant species (Myriophyllum elatinoides and Pennisetum purpureum) in the vegetated drainage ditches. However, the ER system decreased the plant height (1.1%) and the number of tillers (9.6%), resulting in a reduction of the total grain yield (6.0%). Moreover, compared with the CK system, the ER system increased CH4 cumulative emission, global warming potential (GWP), and greenhouse gas intensity (GHGI) by 11.1%, 8.1%, and 14.3%, respectively, and decreased N2O by 27.2%, but not statistical significantly (p < 0.05). Even so, by taking the costs of farm operations and carbon costs of greenhouse gas emissions, the net economic benefits by applying the ER system were higher relative to the CK system. Thus, our study provides further understanding of the technology which has the potential to transform sustainable rice production to a more profitable, income generating, and environmentally friendly industry in China.

Abstract Northern China is a major production area for off-season vegetables in Chinese solar greenhouse. Usually, greenhouse gas emission flux and coefficient in Chinese solar greenhouse are higher than those in the open field. The reason for this phenomenon is heavy nitrogen (N) fertilization (esp. chemical N and organic manure N) and frequent irrigation during year-round cultivation. A novel substrate cultivation method for vegetable production in Chinese solar greenhouse, called soil-ridged/substrate-embedded cultivation (SSC), was put forward to reduce environmental pollution and increase use efficiency of nutrients. To clarify the characteristics of SSC root-zone greenhouse gas emissions, and the regulation effects of biochar and DMPP addition, five treatments were designed in Chinese solar greenhouse under the same nitrogen application level, including soil-ridge cultivation (SC, as a control), SSC (peat: vermiculite: perlite (v/v = 2:1:1), SSC-B50% (biochar: vermiculite: perlite,v/v = 2:1:1), SSC-B25% (biochar: peat: vermiculite: perlite, v/v = 1:1:1:1), and SSC-DMPP (SSC supplemented with 1% (w/w) DMPP of N fertilizer). Results showed that SSC improved fruit yield of sweet pepper of by 10.99% compared to SC. SSC-B50% and SSC-DMPP significantly improved sweet pepper growth compared to SSC. Moreover, SSC-DMPP increased sweet pepper yield by 10.30% compared to SSC treatment, while SSC-B50% and SSC-B25% treatments lowered the yield by 47.1% and 13.7% separately. Five treatments presented various root-zone temperature features. Also, substrate pH of SC, SSC-B50%, and SSC-B25% is alkaline, while SSC and SSC-DMPP treatments is acidic. Besides, the Global Warming Potential was significantly mitigated in the SSC cultivation compared with the SC. Similarly, the greenhouse gas intensity decreased from 0.074 to 0.038 kg CO2-eq kg− 1 yield. Compared with the SSC treatment, cumulative N2O emissions were significantly reduced in the SSC-DMPP treatment. The greenhouse gas intensity also decreased from 0.038 to 0.033 kg CO2-eq kg− 1 yield. Thus, we concluded that SSC was a promising method characterized with reduced greenhouse gas emissions and increased fruit yield. Application of DMPP in SSC cultivation significantly reduced N2O emissions. We recommend SSC method use in Chinese solar greenhouse with DMPP addition in substrate to optimize greenhouse gas mission.

Positive Effects

Biochar, that is, carbonized biomass similar to charcoal, has been used in acute medical treatment of animals for many centuries. Since 2010, livestock farmers increasingly use biochar as a regular feed supplement to improve animal health, increase nutrient intake efficiency and thus productivity. As biochar gets enriched with nitrogen-rich organic compounds during the digestion process, the excreted biochar-manure becomes a more valuable organic fertilizer causing lower nutrient losses and greenhouse gas emissions during storage and soil application. Scientists only recently started to investigate the mechanisms of biochar in the different stages of animal digestion and thus most published results on biochar feeding are based so far on empirical studies. This review summarizes the state of knowledge up to the year 2019 by evaluating 112 relevant scientific publications on the topic to derive initial insights, discuss potential mechanisms behind observations and identify important knowledge gaps and future research needs. The literature analysis shows that in most studies and for all investigated farm animal species, positive effects on different parameters such as toxin adsorption, digestion, blood values, feed efficiency, meat quality and/or greenhouse gas emissions could be found when biochar was added to feed. A considerable number of studies provided statistically non-significant results, though tendencies were mostly positive. Rare negative effects were identified in regard to the immobilization of liposoluble feed ingredients (e.g., vitamin E or Carotenoids) which may limit long-term biochar feeding. We found that most of the studies did not systematically investigate biochar properties (which may vastly differ) and dosage, which is a major drawback for generalizing results. Our review demonstrates that the use of biochar as a feed additive has the potential to improve animal health, feed efficiency and livestock housing climate, to reduce nutrient losses and greenhouse gas emissions, and to increase the soil organic matter content and thus soil fertility when eventually applied to soil. In combination with other good practices, co-feeding of biochar may thus have the potential to improve the sustainability of animal husbandry. However, more systematic multi-disciplinary research is definitely needed to arrive at generalizable recommendations.

The Impact

Abstract. Livestock waste is one of the contributors to greenhouse gas emissions, therefore it needs proper handling so that the impact on the environment can be minimized. Therefore, socialization and education on waste handling is carried out in an effort to reduce greenhouse gas emissions. Socialization to farmer is done online using whatsapp and zoom meetings platform. Partner are farmers from Cileles and Cilayung Villages, Jatinangor Sumedang District. Waste treatment extension activities as an effort to reduce greenhouse gas emissions are carried out by creating audio visuals in the form of videos and e-flyers uploaded to the media youtube and whatsapp partner groups. In general, farmers understand that the waste generated from their livestock activities must be managed properly, but they do not understand that the impact of improper management will result in greenhouse gas emissions. After extension activities was carried out, there was an increase in farmers' knowledge, both on the potential of livestock waste is one of as a greenhouse gases contributors and good waste processing techniques.Keywords: animal waste, organic fertilizer, greenhouse gasAbstrak.

Greenhouse gases dominated by CO2, CH4, CFC, and N2O come from human (anthropogenic) activities. Efforts to increase the production of rice and corn crops require organic and inorganic fertilizers. The use of chemical fertilizers, which can increase greenhouse gas emissions, is higher than that of organic fertilizers. This study aimed to investigate the reduction in the greenhouse gas emission rate and the increase in crop production caused by organic fertilizer from rice straw and cocoa peel, a community-based sustainable development approach based on education. This research used the mixed method, a descriptive and simple experimental design with the following treatments: t0 = without Compost; ta = straw rice compost dosage of 3 t ha-1; tb = cocoa pod husk dosage of 3 t ha-1; Bta = maize crops + without compost (t0); Btb = maize crops + cocoa pod husk compost (tb); Sta = bare soil + without compost (t0); Stb = rice crops + straw compost (ta); Stc = rice crops + cocoa pod husk compost (tb); and Std = rice crops + without compost (t0). The application of compost reduced agricultural waste and greenhouse gas emissions of CH4 and N2O in both maize and rice fields. Greenhouse gas emissions were reduced by 30 percent compared to those under the application of chemical fertilizers. The utilization of compost as organic fertilizer also increased the production of corn and rice crops compared to that without the application of agricultural waste up to 10.3 tons per ha.
