Increasing Demand

Fertilization for agriculture and plantation nutrition still dominated by chemical fertilizers. Organic fertilizers utilization for soils is believed has not had the same quality as existing fertilizer standards. On the other hand, increasing waste problems has become environmental issues that have not been properly resolved. MSW process by using MBT Method is able to change the waste management system and produce RDF Fluff products as alternative fuels and compost fertilizers. Research have showed that the quality of organic fertilizer from the Mechanical Biological Treatment (MBT) process met the SNI 19-7030-2004 parameters with the total N = 1.38%, P2O5 = 0.66% and K2O = 2.34%. Production cost of making organic fertilizer is lower than NPK and the amount used for ground application is higher than NPK. Market confidence began gradually improving due to consumer increasing demand.

Abstract The application of inorganic fertilizers has been continuously increasing since last many decades globally. Farmers nowadays heavily rely on the use of inorganic fertilizers to meet the production of their farms and gardens. This becomes a concerning environmentally and also health issue. One solution is to decrease the use of inorganic fertilizers and substitute with organic fertilizers. In our previous work, we have developed macroalgae-based organic fertilizer (MbOF) which show promising results in increasing the growth and yield of various crops and plants. However, the quality of the formulated MbOF has never been accessed. In this study, we analysed the organic matter composition and heavy metal safety profile of the MbOF. Our results show that MbOF contains considerably high organic C (43.05 ± 2.56 %). The cumulative content of total-N (1.91 ± 0.78 %), P2O5 (2.20 ± 0.81 %) and K2O (2.18 ± 0.54 %) were also above 4%. Furthermore, the C/N ratio was sufficient (22.54 ± 5.81 %). In addition, heavy metal analyses also show low content of Pb (5.61 ± 0.71 ppm) and Hg (0.29 ± 0.14 ppm). Based on the results, the formulated MbOF could be employed as substitute or used together with inorganic fertilizer to get maximum benefits regarding yield and growth of crops and plants.

15N Abundance

Natural nitrogen isotope abundance (δ15N) has been suggested as a potential indicator for discriminating organic vegetables from their conventional counterparts. However, little is known about the δ15N characteristic of cauliflower (Brassica oleracea L. var. botrytis) under organic production and how the application of chemical fertilizers could affect this characteristic. In this study, δ15N characteristics of cauliflower (including the intra-plant δ15N characteristic) and soil under different fertilization treatments were investigated under field conditions. Five treatments were laid out: control, chemical fertilizers (F4M0), organic fertilizer (F0M4), and chemical fertilizer in combination with organic fertilizer at the ratio of 3:1 (F3M1) and 1:3 (F1M3). Results showed that plant δ15N was positively correlated with fertilizer δ15N and plant root/flower was more sensitive to changes of fertilizer δ15N and soil δ15N than leaf/stem. Distribution of δ15N in different plant parts (especially in flower and leaf) was significantly changed when organic fertilizers were partially or totally substituted by chemical fertilizers, suggesting a comparison of flower δ15N and leaf δ15N might be applicable for the organic identification of marketed cauliflowers. Our results provide fundamental data for the soil- and fertilizer-specific crop δ15N database and indicate that the intra-plant δ15N characteristic could be helpful for organic cauliflower identification.

In the development of vegetable farming by the community, there are fundamental problems which are generally carried out conventionally with the use of synthetic fertilizers and pesticides to determine the success of their farming. With the farming system, the community suffers a lot of losses because the inputs used are relatively expensive and on the other hand the products become cheap because the quality is not guaranteed. The solution to this problem is to develop bio-culture organic fertilizers and bio-urine whose raw materials are available in the region. The partner village development program aims to conduct training on the making and development of liquid organic fertilizer bio-culture and biourine to support the cultivation of organic vegetables. The method of approach applied is technology transfer (TT) and entrepreneurship capacity building (ECB) which is carried out with the Participatory Rural Approach (PRA) approach ) which in its implementation uses the method of lecture/discussion, training, making demo plotting, and assistance. The results achieved in the implementation of this program were that participants were able to make and develop liquid organic bioculture fertilizers and biourin and apply it to their farms as an alternative to chemical fertilizers

Macro Nutrients

Liquid organic fertilizer is a solution from the fermentation of organic materials by involving microorganisms as a destructor of macromolecular compounds into minerals that are easily absorbed by plants. The quality of organic fertilizers is the main ingredient to get productive plants. The quality of organic fertilizer is determined by the concentration of macro nutrients such as nitrogen (N), potassium (K), and phosphorus. Getting high amounts of macronutrients fertilized organically is not easy. Macro-nutrients in organic waste with high concentrations are very difficult to obtain because each organic waste does not have all three macro-nutrients simultaneously. It takes a combination of organic waste to increase the concentration of macro nutrients in organic fertilizers. The combination of tofu whey with banana waste is one technique to obtain organic fertilizers that are high in phosphorus content. This study aims to obtain the effect and conditions of fermentation on the addition of mass of banana waste to produce optimum levels of phosphorus (P) in liquid fertilizer of tofu waste. The type of research used is pre-experimental research. The design of this study used a completely randomized design (CRD) with two factors, namely the first factor was the mass of banana waste (X) (X1 = 250 grams, X2 = 500 grams, X3 = 750 grams) and the second factor was the fermentation time (Y) (Y1 = 14 days, Y2 = 28 days, Y3 = 42 days). Determination of phosphorus content using UV-Vis spectroscopy instrument. Parameters measured were phosphorus (P) levels in liquid organic fertilizer. The independent variables in this study were the mass of banana waste and fermentation time, while the dependent variable in this study was the phosphorus content of the liquid fertilizer produced. The results of the analysis show that the phosphorus content (P) produced is X1Y1 = 0.1%, X2Y1 = 0.5%, X3Y1 = 0.09%, X1Y2 = 0.5%, X2Y2 = 2%, X3Y2 = 1.9 %, X1Y3 = 0.2%, X2Y3 = 0.5% and X3Y3 = 0.5%. There is an effect with the addition of a mass of banana waste as much as 250 grams at a 12-day fermentation time. It can be concluded that the liquid fertilizer produced has exceeded the SNI quality standard.

Reduction of chemical fertilizers and effective use of livestock excrement are required for the realization of sustainable agriculture and reduction of greenhouse gas (GHG) emissions. The purpose of this study was to estimate the reduction rate of GHG emissions represented by comparing global warming potential (GWP) using organic fertilizers instead of chemical fertilizers. The study was conducted in a managed grassland on Andosol in southern Hokkaido for 3 years from May 2017 to April 2020. There were five treatment plots: no fertilizer, chemical fertilizer, manure, slurry, and digestive fluid. Organic fertilizers were applied such that the amount of NPK did not exceed the recommended application rate, and the shortage was supplemented with chemical fertilizers. Fluxes in CO2 caused by heterotrophic respiration (RH), CH4, and N2O were measured using the closed chamber method. Net ecosystem carbon balance (NECB) was obtained as net primary production + organic fertilizer application—RH—harvest. The GWP was estimated by CO2 equivalent NECB and CH4 and N2O emissions in each treatment. Chemical fertilizer nitrogen application rates in the organic fertilizer treatments were reduced by 10% for manure, 19.7% for slurry and 29.7% for digestive fluid compared to chemical fertilizer only, but the grass yields were not significantly different among the fertilizer treatments. The 3-year NECB showed significantly smallest carbon loss in manure treatment, and smaller carbon loss in the organic fertilizer treatments than in the chemical fertilizer only. The reduction rate in the GWP with use of organic fertilizers relative to that of chemical fertilizer was 16.5% for slurry, 27.0% for digestive fluid, and 36.2% for manure. The NECB accounted for more than 90% of the GWP in all treatments. CH4 emissions were < 0.1% of the GWP. On the other hand, N2O emissions accounted for more than 5% of the GWP, and was larger in the order of slurry > chemical fertilizer only > digestive fluid > manure. As a conclusion, these organic fertilizers can be used without no reduction of crop yield instead of chemical fertilizer, however, manure is the best way to increase soil carbon and to decrease GWP, followed by digestive fluid.

Rice Yields

The decline in rice yields as a result of excessive chemical fertilizer (CF) inputs is a matter of great concern in rice-growing regions of Asia. In two-year’s field experiments, the nitrogen, phosphorus, and potassium (NPK) status, growth characteristics and yield of rice were examined by application of poultry manure (PM), cow manure (CM) and compost (CP). Organic fertilizers were applied as EMN (estimated mineralizable N) based on their total N content. Six treatments were assigned in a randomized complete block design: (1) no-N fertilizer (N0); (2) 50% CF (CF50), (3) 100% CF (CF100); 50% CF + 50% EMN from (4) PM or (5) CM or (6) CP. Compared with CF100, the CF50PM50 (total N ≥ 4%) accumulated higher N, P and K content in leaf, sheath, panicle and seeds, resulting in greater growth and yield. The CF50PM50 increased yield by 8.69% and 9.70%, dry matter by 4.76% and 5.27% over CF100 in both years. The continuous application of CF50CM50 (total N < 4%) and CF50CP50 (total N < 4%) treatments led to similar NPK contents but higher yields than those of CF100 treatment in 2018. In conclusion, the organic fertilizer (total N ≥ 4%) with the EMN method enhances higher N availability in each year. Continuous application of organic fertilizer (total N < 4%) over two years effectively increased N availability in the second year. The 50% organic fertilizer (total N ≥ 4%) and 50% CF led to increased NPK availability and rice yields over the 100% CF treatment, reducing CF usage and leading for sustainable agriculture.
