“…This could be explained by the naturally high nutrient content of the original chicken manure (total N 4.64% vs. 2.44%, P 2 O 5 2.52% vs. 2.08%, and K 2 O 2.64% vs. 1.69% DW), as well as its lower C/N ratio (11 vs. 20.9), which favors mineralization. Manure from forage-based diet animals tends to have lower soluble hydrolysable organic matter and mineral content than manure from concentrate-based diet animals such as chicken [31,33,73]. In the specific case of P, orthophosphate ions are subject to immobilization processes, precipitation reactions, and fixation reactions, which are strongly influenced by pH.…”

Using locally accessible organic materials as fertilizers in hydroponics can represent a sustainable alternative to the synthetic mineral fertilizers typically used. This study aimed at developing a simple bioponic method using chicken or goat manure on lettuce (Lactuca sativa var. Lucrecia) in the nutrient film technique, requiring few inputs. The first experiment compared nutrient solutions made from chicken or goat droppings and mineral fertilizers in terms of physico-chemical parameters, plant yields, and shoot mineral content. Organic solutions were produced in two main stages before being used on plants: (1) a simple manure maceration in water to produce stock solution, followed by (2) an aerobic digestion of the filtrated and diluted stock solution according to the total mineral nitrogen (TMN). The second experiment compared different concentrations of chicken manure stock solution (60, 80, 100, or 120 mg/L TMN) to a control mineral solution. In the first experiment, both organic treatments resulted in yields significantly lower than those of the control, probably due to nitrogen scarcity. In the second experiment, all organic treatments resulted in wet and dry shoot masses similar to those obtained with the inorganic control treatment. Produce quality was also improved, with lower shoot nitrate content. Important nitrogen losses occurred in the organic solutions during aerobic digestion, particularly in the goat treatment and in the highly concentrated treatments in stock solution during the 2nd experiment (~50–65% TMN losses). This was probably caused by the presence of residual organic matter, which resulted in excessive microbial development. It can be concluded that chicken and goat manure are suitable fertilizers for lettuce hydroponic production using this method; however, further research should be carried out to improve mineralization during digestion steps.

“…Thus, increasing atmospheric nitrous oxide by chemical fertilizer application give negative effect that bring to greenhouse effect. The nitrogen cycle includes biological nitrogen fixation (BNF), providing for the bulk of the nitrogen available to plants via direct and indirect influences on microbial activity and nutrient availability, significant in sustaining or improving soil fertility and plant nutrition [6]. Oil palm get benefits during bacteria's nitrogen fixation due to transformed of nitrogen gas (N2) into available form for plant uptake [7].…”

Oil palm plantation sector is the most important contribution to economic growth in most Asian countries and most plantations rely on chemical fertilizer for growth which caused harmful to environment. As we can see, nitrogen in the atmosphere can be fixed by the microorganism through the process of nitrogen fixation where it also can act as a bio-fertilizer. Therefore, three objectives are covered in this study, which 1) to review studies on microbial activities and their interaction with plant in soil, 2) to evaluate the effectiveness of organic matter that enhance microbe activity and also N-fixation and 3) to identify the species of bacteria and fungi used for oil palm inoculation in previous studies. A review of microbial activity has been presented in order to highlight the potential interaction where endophytic BNF bacteria have successfully increase the development of oil palm seedlings. Combination of EFB and cow dung in vermicompost technique showed the higher number of E. eugeniae (32 earthworms) thus increases available plant nitrogen. Microbial inoculation such as Glomus aggregatum, Bacillus salmalaya strain 139SI and Herbaspirillum seropedicae gives positive impact towards growth performance. The findings provided successful significant proof that microbe inoculation has a favorable influence on oil palm FFB production.
