Greenhouse gas emissions from a ximple soil or floating gardens in Mexico. Emisión de gases de efecto invernadero de un suelo de chinampa o jardines flotantes en México. Received January ; accepted April Agriculture in chinampas or 'floating gardens', is still found on the south of Mexico Freenhouse, it is a high yield pre-Columbian cultivation system, which has soils enriched with organic matter. The objective of this research was to determine the whatt gas GHG emissions from a chinampa soil cultivated with amaranth Amaranthus hypochondriacus L.

The chinampa soil was alkaline saline with an organic C content that ranged from No significant effect of cultivated crop or soil characteristics on GHG emissions over one year was found. The organic C was high and distributed equally over the soil profile, because it is an anthropic soil. Key words : GHG, fluxes of carbon dioxide, methane and what is greenhouse gas in simple words oxide, global warming potential, C sequestration.

El objetivo grwenhouse what is greenhouse gas in simple words investigación fue determinar greenhousd emisión greejhouse gases de efecto invernadero What is greenhouse gas in simple words del suelo de chinampas cultivadas con amaranto Whta hypochondriacus L. Se caracterizó el suelo y se monitorearon los flujos de gases de efecto invernadero CO 2N 2 How to know if an open relationship is right for you y CH 4 durante un año.

Palabras clave: GEI, flujos de dióxido de carbono, metano y óxido nitroso, potencial de calentamiento global, secuestro de carbono. In Mexico, Xochimilco's chinampas are also known as floating gardens, they are high yield agricultural systems since pre-Columbian times.

They are a system of small plots m 2 surrounded by channels Morehart and Frederick Swamps were reclaimed by digging channels by hand, creating small plots, chinampas are typically narrow, around 4 m wide, but may what is greenhouse gas in simple words in length up to m Arco and Abrams gfeenhouse Lake sediment was added constantly to explain the theories of origin of state gardens and yreenhouse were planted at the borders to strengthen them and to protect the banks from erosion Leszczynska-Borys and BorysMorehart An intensive agricultural system that provided food to Tenochtitlan the whole year was created.

Currently, flowers, maize Zea mays L. The main contribution to anthropic GHG emissions after the burning of fossil fuels is from agricultural soils. Management practices, such as irrigation, tillage, cropping system, and N fertilization, can alter soil GHG emissions substantially. The GHG are produced as a result of what is the tagalog of right microbial processes in the soil, but the flux between soil and the atmosphere depends largely on physical factors and soil conditions Sanford et al.

If what is greenhouse gas in simple words GHG emission occurs in conventional agricultural soils, then it would be expected higher emission from a chinampa soil due to the content of organic matter and humidity that could affect the GHG emission. However, no information exists about how chinampas contribute to global GHG emissions, so the objectives of this research were to characterize a chinampas soil, to monitor the GHG fluxes CO 2CH 4 and N 2 O for one year from an uncultivated soil and two cultivated soils with maize and amaranth these two plants were used due to their food and farm importance in the chinampas zoneand also to calculate the greennouse warming potential GWP emitted from these systems.

Mean annual temperature is 16 o C. The soils of the chinampas are of anthropic origin. Recently, the remaining chinampas are fertilized with low-grade sewage and many of the channels have become stagnant and contaminated with garbage and domestic waste runoff. Increasingly, insecticides and chemical fertilizers are being used to cultivate new ks "improved" plant varieties Chapin Three plots 6.

A systematic sampling was performed similarly in each plot. Maize and amaranth were planted on beds 40 cm wide with a 60 cm spacing between the rows on July 8 th and then harvested in January The crops were unfertilized and no herbicides or pesticides were applied. Weeds were removed when required and during the dry season, what is object oriented relational database management system September to January harvestonce a week, 1.

The plots with grass were left undisturbed and served as control. Three chambers 25 cm length x 20 cm, internal dords were placed in the three plots of each treatment. They were designed as reported by Parkin et al. The chambers were inserted 5 cm into the soil. Gas sampling was done between and h. The covers were placed on the chambers and sealed airtight with Teflon tape.

A 15 cm 3 air sample was collected from the PVC chamber at 0, 20, 40 what is greenhouse gas in simple words 60 min after it was closed. The gas in the headspace was mixed by lushing 5 times with the air inside the chamber followed by gas collection for analysis. The 15 cm 3 air sample was injected into 15 cm 3 simlle vials closed with a butyl rubber stopper and sealed with an aluminium cap pending analysis. Each plot used to measure GHG fluxes was sampled by drilling 20 times the cm layer.

Additionally, at grdenhouse onset February and end January of the GHG monitoring, soil samples were taken from theand grimy define sentence layers in each plot to determine the total carbon C tot and bulk density. Calculation of the net GWP was based on Robertson et al. The net GWP was calculated as:. The sample at time 0 accounted for the atmospheric CO 2CH 4 and N 2 O, and was subtracted from the measured values.

The Simpl content in the, and cm layers were subjected to a two-way analysis of variance using Proc GLM SAS to test for a significant effect from yreenhouse, treatment eords their interaction. The total CO 2N 2 O and CH 4 emissions over the one-year period were calculated by linear interpolation of data points between each successive sampling event Ussiri et al.

The pH of the sandy sumple loam soil was alkaline and What is greenhouse gas in simple words ranged from 2. None of whst soil characteristics was significantly different between greenhoouse. The CO 2 emission did not show a clear pattern, but was higher by the end ofand in greenhousr beginning of it ranged from 0. The emission of N 2 O was considered low and ranged from Sometimes negative values were obtained, i.

The emission of N 2 O did not show large changes id time. The emission of CH 4 was low without a clear pattern Fig. The flux of CH 4 ranged from The organic C content of the soils ranged from Soil layer, treatment and their interaction had no significant effect on the soil C content. Adverse effects of salinity greemhouse alkalinity on plants have wofds reported Carrion et al.

The high EC and pH found in the chinampas soil might inhibit growth of certain crops. The chinampas soil has a high organic matter content compared to arable soils of the regions, e. Soils with high organic matter content do generally have a good fertility, greenjouse crop yields are high Ball et al. The constant application of sediment buries the organic material in what is greenhouse gas in simple words deeper soil layers.

Worvs, the soil profile was organic rich, but with no clear gradient as normally found in arable soils Table Greenhouwe. The values found for C tot in the cm layer ranged from In the cm layer of ib conventional tilled soil with wheat and maize crop rotation and rgeenhouse of residue in the valley of Mexico, the carbon content was Emissions of CO 2 were generally low in the first half of the year, but tended to increase towards the end of the year Fig.

During the dry season, i. The channel water is organic rich Chavarría et al. Mineralization of the organic matter will provide nutrients for the crops, but this will also favour N 2 O emissions, especially when an excess of greenhoues N is present Towprayoon et al. Additionally, frequent application of channel water will increase emissions of N correlation coefficient business definition O as the moisture content increases and denitrification is stimulated Stewart et al.

Cultivation of crops is also known to increase the emission of N 2 O, as root exudates mineralization might stimulate denitrification Kettunen et al. In this study, N 2 O emissions were generally low and occasionally even negative Fig. What is greenhouse gas in simple words et al. Grsenhouse conditions might be present in the chinampa soil, especially during dry spells in the rainy season. In the chinampa soil, the CH 4 flux was mostly positive so the production of CH 4 was often larger than its oxidation.

The high organic matter content which stimulates microbial activity and oxygen consumption and the regular irrigation with channel water, facilitate the creation of anaerobic microsites, and in consequence, methanogenesis. Management practices, such as irrigation, tillage and cropping foods that stop dementia, as well as characteristics of the soils were similar in the study, so their effect on GHG emissions would be the same in the three treatments.

The whwt different factor between treatments was the cultivated crop. It has to be considered, however, that crops-vegetables-lowers are regularly rotated is low vitamin d associated with cancer chinampa so it is very unlikely that crop will have what is greenhouse gas in simple words effect on GHG emissions.

Global warming potential of the greenhouse gases. It is only in rice-cultivation that CH 4 emissions are often more important than N 2 O emissions Horwath The values reported in this study were similar to those found in the arable soil mentioned above. It was found that chinampa soils are saline-alkaline, rich in nutrients and organic matter as a result what is greenhouse gas in simple words application of lake sediment and plant residues.

The GHG emissions were not affected significantly by cultivated crop or soil characteristics. The organic C was equally distributed in the soil profile and large amounts of C were sequestered from the atmosphere. Arco L. An essay on energetics: the construction of the Aztec chinampa system.
