Abstract:

This paper presents the performance evaluation of a double chamber microbial fuel cell (MFC) to obtain the maximum amount of power production. Previous works have shown that the performance of a double chamber MFC varies depending on the design of the MFC and the type of waste water. Therefore, various MFC tests were conducted to obtain the maximum amount of power production by varying the distance of electrodes and thickness of the electrode. The types of water were also varied (i.e., fertilizer water, lake water, and soil water) to highlight the effect of the expected different amount of mic

Abstract:

Water conservation in nursery systems is an ever-increasing focus, yet there is relatively little guidance for growers producing seedlings intended for restoration regarding how practices such as subirrigation influence plant growth in the nursery and after outplanting. Our study investigated red-flowering currant (Ribes sanguineum Pursh) seedling development and early field performance using different fertilizer treatments under a subirrigation regime. Plants were fertilized with 1) incorporated organic fertilizer, 2) incorporated controlled-release fertilizer, 3) top-dressed controlled-relea

The agricultural sector is the economic basis of the people of Kedungrejo Village, so there are many problems in the agricultural sector in Kedungrejo Village. One of the problems being faced is the use of inorganic fertilizers. Most farmers use inorganic fertilizers to increase crop production in a short time. However, if used intensively, the use of inorganic fertilizers or chemical fertilizers will have a negative impact on soil fertility, soil pollution and can even lead to water pollution. For this reason, in dealing with this problem, it is highly recommended that organic fertilizer be a

Initially, chemical fertilizers were able to increase crop yields but over time yields declined and soil conditions became more critical. Chemical fertilizers can kill organisms in the soil. This is because chemical fertilizers contain compounds such as methane and ammonia which pollute the environment.
