Comparison of Nutrient Content in Acid Treated Fish Waste Compost with Normal Fish Waste Compost

Critical land area in Indonesia was recorded 23.25 million ha in 2000, and increased to 77.8 million ha in 2007, efforts are needed to optimize it. However, the existence of agricultural waste, livestock waste and sewage abundant fishery potential to increase soil fertility has not been utilized to the maximum. This study aimed to determine the macro nutrient content available in waste after the fermentation process. This research is an experimental research conducted in a laboratory to find out the content of: N, P, K, C / N ratio. The method for making liquid organic fertilizer is fermentation for one month using EM4 effective microorganisms, then analyzed using Spectrometry and Titrimetry Kjeldahl. The results showed that the highest N content was in bio urine fermentation (0.126%), fish waste (0.035%) and mixed waste (0.028%); The highest P was found in cattle rumen (7.239 mg / L), bio urine (5.234 mg / L), and seaweed (4.689 mg / L), and highest K was found in fruit waste (7, 801 mg / L). The highest C / N ratio was found in seaweed (55,643%) and fruit waste (27,857%). The conclusion is that agricultural waste, livestock waste, and fisheries waste after 1 month of fermentation contain adequate nutrients for optimizing critical land.

Organic fresh products are appreciated and are gaining a good reputation regarding human health and environmental concerns. Despite the fact that hydroponics are commonly used in vegetable production, growers are looking for sustainable cultivation systems. Therefore, the objective of this study was to investigate the effect of using an organic-based nutrient solution (NS) derived from fish waste in a hydroponic system on the vegetative growth and production of lettuce compared to a conventional inorganic NS. Plant growth, yield, physiological and nutrient content parameters were determined. The results revealed that the overall growth and fresh biomass of the organic NS grown lettuce were relatively lower than those of the inorganic NS. Stomata density was significantly higher in inorganic grown lettuce compared to the organic one. However, the total chlorophyll, carotene, phenolic compounds, and flavonoid contents, as well as antioxidant activity were significantly higher in lettuce grown in organic NS compared to the inorganic one. Leaf nutrient content at harvest was significantly impacted by the type of used fertilizer. Based on these findings, in hydroponic system, organic liquid fertilizer derived from fish waste (as an alternative NS source) requires further improvements to achieve optimal growth and yield comparable to that of conventional inorganic NS.

The effects of the pesticide Abate on the ovary of the cat fish Heteropneustes fossilis (Bloch.) was studied by observing the vitellogenesis of the fish. The LC50 of Abate (0.64 ppm) after 24, 48, 72 and 96 hours of exposure to the fish was determined to be 14.3, 10.0, 6.61 and 5.13 ppm, respectively. The glycogen contents in the normal fish were lowest (6.0 mg/g) and highest (21.96 mg/g) in December and August, respectively; the protein contents were lowest (102.65 mg/g) in August and highest (424.17 mg/g) in December; whereas, the cholesterol was the lowest (9.32 mg/g) in November and highest (15.76 mg/g) in August. In the Abate treated fish, the lowest and highest contents of biochemicals were: 3.58 and 17.10 mg/g of glycogen in December and August, respectively; 80.44 and 378.34 mg/g of protein in December and August, respectively; and 7.15 and 12.92 mg/g of cholesterol in December and August respectively. The results show that the pesticide Abate has the potentiality to alter the vitellogenesis of the fish. DOI: http://dx.doi.org/10.3329/bjz.v40i2.14314 Bangladesh J. Zool. 40(2): 207-212, 2012

The study investigated effect of vermicompost enriched with fish silage on the growth, yield and biochemical constituents of cowpea. The experiment was laid out in a randomised complete block design (RCBD) in three replicates with plot size of 2.0×2.0 m each. The treatments were chemical fertiliser (CF) (100 kg urea + 300 kg single super phosphate ha-1), fish silage enriched vermicompost (VCS) (3.33 t of enriched vermicompost and 300 kg single super phosphate ha-1) and vermicompost (VC) (4.5 t vermicompost + 300 kg single super phosphate ha-1). Data on growth and yield parameters of cowpea were analysed. Chlorophyll and carotenoid content of the leaves were also estimated. Results showed that cowpea performed best with the enriched vermicompost in terms of average yield of fruits per plant (209.27 g), plant height (114.2 cm), total number of branches per plant (13.4), weight per fruit (4.41 g) and number of seeds per fruit (10.5). Cowpea plants given inorganic fertiliser had a better biochemical profile with higher total chlorophyll (37.52 mg g-1) and carotenoid (1.497 mg g-1) content than the organic manure treated plants. Results revealed that enriching vermicompost with fish silage is a potential option for improving the nutrient content of vermicompost, resulting in higher crop production by converting fish waste into a useful byproduct.

Food Composition Data ◽

Definition Of

Food composition data (FCD) comprises the description and identification of foods, as well as their nutrient content, other constituents, and food properties. FCD are required for a range of purposes including food labeling, supporting health claims, nutritional and clinical management, consumer information, and research. There have been differences within and beyond Europe in the way FCD are expressed with respect to food description, definition of nutrients and other food properties, and the methods used to generate data. One of the major goals of the EuroFIR NoE project (2005 - 10) was to provide tools to overcome existing differences among member states and parties with respect to documentation and interchange of FCD. The establishment of the CENs (European Committee for Standardisation) TC 387 project committee on Food Composition Data, led by the Swedish Standards Institute, and the preparation of the draft Food Data Standard, has addressed these deficiencies by enabling unambiguous identification and description of FCD and their quality, for dissemination and data interchange. Another major achievement of the EuroFIR NoE project was the development and dissemination of a single, authoritative source of FCD in Europe enabling the interchange and update of data between countries, and also giving access to users of FCD.

School Food Environment

This paper examines the changes to procurement for school food environments in Canada as a response to changes to nutrition regulations at the provincial level. Interviews with those working in school food environments across Canada revealed how changes to the nutrition requirements of foods and beverages sold in schools presented opportunities to not only improve the nutrient content of the items made available in school food environments, but also to include local producers and/or school gardens in procuring for the school food environment. At the same time, some schools struggle to procure nutritionally compliant foods due to increased costs associated with transporting produce to rural, remote, or northern communities as well as logistic difficulties like spoilage. Although the nutrition regulations have facilitated improvements to food environments in some schools, others require more support to improve the overall nutritional quality of the foods and beverages available to students at school.

Soil biological properties and CO2emission were compared in undisturbed grass and regularly disked rows of a peach plantation. Higher nutrient content and biological activity were found in the undisturbed, grass-covered rows. Significantly higher CO2fluxes were measured in this treatment at almost all the measurement times, in all the soil water content ranges, except the one in which the volumetric soil water content was higher than 45%. The obtained results indicated that in addition to the favourable effect of soil tillage on soil aeration, regular soil disturbance reduces soil microbial activity and soil CO2emission.

Npk Fertilization

Az Országos Műtrágyázási Tartamkísérletek (OMTK) tizenkét NPK kezeléskombinációjában, kilenc termőhelyen vizsgáltuk az NPK-trágyázás hatását az őszi búza és a kukorica termésére és a talajok 0,01 M CaCl2-oldható tápelemtartalmára. A termőhelyek: Bicsérd (BI), Hajdúböszörmény (HA), Iregszemcse (IR), Karcag (KA), Keszthely (KE), Kompolt (KO), Mosonmagyaróvár (MO), Nagyhörcsök (NA), Putnok (PU). Az NPK kezelések: 000, 101, 111, 121, 201, 220, 221, 222, 331, 341, 421, 441. A N- és P-kezelések a kódoknak megfelelően 50 kg N, ill. P2O5·ha−1, a K-adagok 100 kg K2O·ha−1 hatóanyag-mennyiséggel növekszenek. Az őszi búza termésadatok a 23., 24., 27., 28. és 31. évi kísérletekből, a kukoricatermések a 25., 26., 29. és 30. évből származnak.Az NPK-kezelések jelentősen növelték az őszi búza és a kukorica öt-, illetve négyéves átlagtermését, szignifikáns különbségek jöttek létre a termőhelyek átlagában. Az NPK-kezelések különböző érvényesülése az egyes termőhelyeken az eltérő ökológiai viszonyok, köztük a különböző eredeti tápelemtartalom és szolgáltató képesség következménye.Az NPK-kezelések hatására a talajok 0,01 M CaCl2-oldható tápelemtartalma is jelentősen változott. A növények tápelemigényét meghaladó kezelések tartamhatásaként tápelem-felhalmozódás igazolható mindhárom tápelem esetében. A növények szükségletét meghaladó N-adagok, a karbonátos talajokat és a nagy agyagtartalmú kompolti (KO) talajt kivéve csökkentették a talaj pH-t. A másodfokú görbék az őszi búza ötéves termésátlaga és a 0,01 M CaCl2-ban mért összes-N, P- és K-tartalom közötti összefüggéseket szemléltetik termőhelyenként.A legnagyobb kezeléshatások azokon a talajokon igazolhatók, melyeken a kontroll 0,01 M CaCl2-oldható összes-N értéke kisebb, mint 5–10 mg·kg−1. A 15,0 mg·kg−1 érték felett altalaban nem érvényesült a nitrogén termésnövelő hatása. Kivételt képez a tápanyagban gazdag, hajdúböszörményi nem karbonátos réti talaj. A foszfor termésnövelő hatása 2,0 mg P·kg−1 érték felett — a karbonátos réti talaj kivételével — általában nem érvényesül. Az összefüggéseket jellemző R2 meghatározottsági tényezők a legkisebbek az őszi búza és a talaj 0,01 M CaCl2-oldható K-tartalma között, ami az egyéb tényezők nagyobb szerepére utal.A bemutatott eredmények igazolják, hogy a 0,01 M CaCl2-oldható N-, P- és Kfrakciók alkalmasak a tápanyaghiány és -felesleg jellemzésére. Egyben igazolják, hogy az eltérő ökológiai viszonyok között nagyobb terméskülönbségek jöhetnek létre, mint a kezelések hatására. A környezetkímélő tápanyag-gazdálkodás megköveteli a tápanyagok eltérő érvényesülésének figyelembevételét.A termésadatok átengedéséért köszönet az OMTK Hálózati Tanács elnökének, titkárának, és valamennyi kísérletfelelősnek.
