Abstract The use of chemical fertilizers in agriculture has caused soil degradation and is harmful to human health. Organic fertilizers made from animal waste have received worldwide attention because they are not detrimental to health or the environment. This paper describes the effect of using organic fertilizers from chicken manure on the growth of papaya plants. A completely randomized design was used in this study using two factors and three repetitions; the variations of the fertilizers given were 0, 50, 100, 150, and 200 g. This study informed that organic chicken manure had a significant effect on the growth of oil palm and papaya plants. The best growth is oil palm and papaya plants given 200 g of organic fertilizer from chicken manure.

Study Results

Assessment for increasing productivity of suboptimal land with using three kinds of organic fertilizer and six rice varieties had been conducted in the Debowae village, Waeapo district, Buru regency at 2011.  Purpose of the assessment were to determine the effect of three types organic fertilizer and the use of six Inpara varieties to growth and productivity of rice in sub-optimal land. Study used a split plot design with three replications (farmers as replicates), where the main plot was three types of organic fertilizers (livestock manure, granular organic, and petroganic), while the subplot was 6 varieties Inpara (Inpara 1, Inpara 2, Inpara 3, Inpara 4, Inpara 5, and Indragiri). The soil types at the study site based on soil classification were Endoaquepts with soil fertility status was low. The study results  showed  that  the use of organic  manure combined with inorganic fertilizers,  both  from  livestock manure, while granular organic and petrogranic, gave an average crop growth and yield better than the results obtained by farmers outside of the study. Average petroganic fertilizer had a better growth and higher crop yields compared to other organic fertilizers. The six varieties of rice swamps that were examined (Inpara 1, Inpara 2, Inpara 3, Inpara 4, Inpara 5, and Indragiri) had the average growth and better yields than rice varieties used by farmers outside of the study (2.75 t ha-1). Varieties Inpara 4, Indragiri, Inpara 1 and  Inpara 2 had average yield above 7 t ha-1, while Inpara 3 and  Inpara 5 average above 4 t ha-1. Combination of granular organic fertilizer with Inpara 4 variety and petroganic with Indragiri variety had the best results (8.37 and 8.02 t ha-1), while the lowest yield (4.48 t ha-1) was reached at combination of  livestock manure with Inpara 5 variety.Keywords: adaptive varieties, land and plant management, organic fertilizers, suboptimal land [How to Cite: Marthen PS and MLJ Titahena. 2014.

Ecuador es el tercer exportador de rosas a nivel mundial. Un factor clave para la competitividad internacional es calcular y reducir las emisiones de gases de efecto invernadero (GEI). Por ello, se calculó la huella de carbono (HC) del cultivo de rosas en Ecuador, tomando como caso de estudio la Empresa Ecoroses S.A. en el año 2015. La empresa está ubicada en el cantón Mejía, provincia de Pichincha y dedica el 100% de su producción a las rosas. La HC se calculó mediante dos metodologías: GHG Protocol y PAS 2050, considerando los límites del sistema “de la cuna a la puerta”. Los factores de emisión fueron recopilados de bases de datos internacionales como IPCC y Ecoinvent v2.2. El resultado de la HC fue de 3,75 kg CO2eq/kg de rosa exportada. Las tres fuentes de emisión de GEI que más afectan son: los productos agrícolas (37,7%), la energía eléctrica (13,3%) y el uso de combustibles fósiles (10,95%). Esta HC duplica a la del cacao seco y es más de 8 veces mayor que la del banano nacional. Por ello, se propone implementar buenas prácticas ambientales para reducir los GEI, en concreto, fertilizantes orgánicos, ahorro energético y biocombustibles. Abstract Ecuador is the third largest exporter of roses worldwide. A key factor for the international competitiveness is to calculate and reduce greenhouse gases (GHG). For this reason, we calculated the carbon footprint (CF) of the cultivation of roses in Ecuador, taking as a case study the Company Ecoroses S.A. in the year 2015. The company is located in the canton Mejia, province of Pichincha, and dedicates 100% of its production to roses. The CF was calculated using two methodologies, GHG Protocol and PAS 2050, considering the limits of the system “from the cradle to the door”. The emission factors were compiled from international databases such as IPCC and Ecoinvent v2.2. The result of the CF was 3,75 kg CO2eq/kg of rose exported. The three sources of emission of GHG that most affect are: agricultural products (37,7%), electrical energy (13,3%), and the use of fossil fuels (10,95%). This CF doubles that of dry cocoa, and is more than 8 times higher than that of domestic bananas. Therefore, the implementation of good environmental practices is proposed to reduce GHG, specifically, organic fertilizers, energy saving, and biofuels.

Ensuring food security of the state provides for obtaining high yields of agricultural crops and the development of livestock facilities. The aim of the investigation is to develop an accelerated biotechnological preparation of sewage and livestock manure from livestock farms for irrigation of pastures and fertilization of fields for forage crops. Closed-loop systems for products output on pig farms and cattle farms using biotechnology for the preparation of livestock manure for irrigation of fields in the production of forage crops have been developed. The biotechnology of accelerated preparation of sewage and liquid livestock manure is based on the principles of their mechanical separation into fractions with the subsequent preparation of liquid concentrated organic fertilizers using nutraceuticals, which speed up the processes of their preparation in a much shorter time than using traditional technologies. A closed-loop system for products output on sheep and pig farms and cattle farms using biotechnology is proposed. The basis of biotechnology in the processing of solid livestock manure is the principle of accelerated components composting using nutraceuticals. The implementation of accelerated preparation system of sewage and livestock manure for irrigation of pastures and fertilization of fields for forage crops contributed to an increase in their yield up to 20.54%. At the same time, the milk yield per forage cow increased by 8.47-14.20%; average daily weight gain - by 13.30–47.73%.

The Maltese agricultural sector faces many challenges including lack of organic matter in its soils. The use of organic fertilizers such as cattle or rabbit manure partly addresses this problem. Different doses of manure of rabbit and cattle manure at specific irrigation regimes were used to assess the growth of crops and production of fruit on aubergine and green pepper plants. The overall mean number of green peppers recorded was significantly different than the mean number of aubergine for all four doses of manure applied, using both rabbit and cattle manure, up to an optimum mean number of fruit produced, the optimum being reached at dose 3 for green peppers and dose 4 for aubergines. Additionally, the mean number of fruit was significantly higher when grown in rabbit than in cattle manure. The mean weight of fruit recorded varied significantly between green peppers and aubergines at the highest dose of rabbit manure. When Nitrogen Use Efficiency (NUE) was investigated, the highest nutrient efficiencies were achieved at the higher fertilizer application rates of rabbit manure while for aubergines, the weight increase was not as significant and it may therefore be possible to compromise yield for a better efficiency.

The study on soil organic matter (SOM) is of great importance to regional cultivated land use and protection. Based on data collected via continuous and high-density soil samples (0–20 cm) and socio-economic data collected from household survey and local bureau of statistics, this study employs geostatistics and economic statistical methods to investigate the spatial-temporal variation of SOM contents during 1980–2010 in the urban fringe of Sujiatun district in Shenyang City, China. We find that: (1) as to temporal variation, SOM contents in the study sites decreased from 30.88 g/kg in 1980 to 22.63 g/kg in 2000. It further declined to 20.07 g/kg in 2010; (2) in terms of spatial variation, the closer to city center, the more decline of SOM contents. Contrarily, SOM contents could even rise in outer suburb area; and (3) SOM content variation may be closely related to human factors such as farmers’ land use target and behaviour including inputs of chemical and organic fertilizers, types of crops and etc. These findings are conductive to grasp the overall trend of SOM variation and the influence of farmers’ land use behaviour on it. Furthermore, they could provide support for policymakers to agricultural planning and land use monitoring, which consequently aids the improvement of soil quality and food production in the urban fringe areas.
