Abstract

Biochar is recognized as a versatile and sustainable tool for improving agricultural and environmental conditions due to its unique physicochemical properties, such as soil fertility, nutrient retention and water holding capacity. The presence of biochar, which contains stabilized carbon, not only has a positive impact on plant growth and crop yields through microbial activity, but can also act as a sorbent to remove contaminants from soil and water. However, the use of biochar in soil and its effects on ecosystem services depend on several factors. This article explores the impact of biochar use on soil and the potential to address ecosystem service challenges by improving soil composition, increasing access to water, and removing contaminants, all to promote sustainable agriculture. The method of this article consists of a literature review by collecting data from various sources such as scientific journals, books and seminar proceedings. The data obtained were qualitatively analyzed to review and identify the information, resulting in a critical and comprehensive explanation and discussion of the role of biochar in improving soil and environmental quality for environmental services. The results of the literature review are presented in the form of a coherent, systematic and critical narrative. The results of this article review indicate that on-farm biochar application contributes significantly to climate change mitigation through various mechanisms, including biochar's ability to sequester carbon, improve soil quality, and minimize greenhouse gas emissions.

Abstract

Demand for soybeans in Indonesia continues to increase along with population growth, but productivity remains low and dependent on imports. One of the key factors affecting soybean productivity is seed quality, which often deteriorates during storage. Seed invigoration, which includes techniques such as hydration-dehydration, hydropriming, and osmopriming, is a possible solution to improve soybean seed viability and vigor. This research used the literature survey method to collect and analyze data from various scientific sources. The results show that seed invigoration can improve the quality of soybean seeds by improving the germination process, increasing vigor, and optimizing water uptake. These techniques are especially important when seeds are sown in non-ideal conditions, such as arid or high salinity areas. Thus, the application of invigoration techniques has the potential to be an effective strategy for increasing soybean productivity in Indonesia and reducing import dependence.
