Much has been written about the chinampas of central Mexico. One of the commonly repeated themes is that these wetland fields were self-irrigated from below in a process known as sub-irrigation. According to this model, water infiltrates the planting platforms from adjacent canals and then rises to the root zone by capillary action. Thus, chinampas are thought to have needed little supplemental irrigation, and produced dependable and high yields. Here I report the results of field and lab… 
The Chinampa: An Ancient Mexican Sub‐Irrigation System
The Chinampa is an agro‐hydrological system practised for many generations, built over shallow lacustrine wetland areas near Mexico City. It was developed by the Aztecs, a pre‐Hispanic culture who
Chinampas: An Urban Farming Model of the Aztecs and a Potential Solution for Modern Megalopolis
Urban horticulture is not as new as many people think. Throughout history, different techniques have been used to ensure sustainable urban agricultural production. A good example of this is the
Irrigation: Water Resources, Types and Common Problems in Egypt
Water is the most essential substance for human being and living organisms. Water scarcity in Africa is mainly economic due to the poor management of water resources. The Nile River is the major
Root length density and water uptake distributions of winter wheat under sub-irrigation
As the critical information to study flow transport in soil–plant systems, root distributions and root-water-uptake (RWU) patterns have been studied extensively. However, most root distribution data
Ecological engineers ahead of their time: The functioning of pre-Columbian raised-field agriculture and its potential contributions to sustainability today
The need to reconcile food production, ecosystem services and biodiversity conservation has spurred the search for more sustainable ways of farming. Archaeology offers examples of prehistoric
Applications of xerophytophysiology in plant production - peanut cultivation with the AnM method
The high leaf turgor maintenance is considered as the main one of the mechanisms for the yield increasing effect of the AnM treatment.
Solute Transport Under Water Table Fluctuations in a Fine Sand and a Sandy Clay Loam Soil
The redistribution of solutes within the soil profile caused by water table fluctuations by making use of a non-reactive tracer in laboratory studies on soil columns was dominantly attributed to convective movement of solute and was considered to be little influenced by diffusion.
Aquaponics : A Potential Integrated Farming System for Sustainable Agriculture and Aquaculture
Challenges to sustainability center around balancing the aquaponic system environment for the optimum growth of three organisms, maximizing production outputs and minimizing effluent discharges to the environment.


Wetland Agriculture in Pre-Hispanic Mesoamerica
U NTIL the late 1960s the swidden thesis was the usual explanation for preHispanic Mayan subsistence.1 By that time archaeological research in the Mayan-occupied lowlands indicated higher population
Yield Potential of Soybean Grown under a Subirrigation/Drainage Water Management System
Combination subsurface irrigation/drainage systems to manage water (add or remove) on poorly drained soils is a relatively new concept in the humid Midwest. The objective of this research was to
Intensive Wetland Agriculture in Mesoamerica: Space, Time, and Form
Abstract Geographers have led the effort to better understand Prehispanic, intensive wetland agriculture (“raised fields”) in Mesoamerica. An overview of that literature provides the database for a
Aboriginal Drained-Field Cultivation in the Americas
The three main types of land reclamation in aboriginal America were irrigation, terracing, and drainage, which was practiced in varied environments, including high-land basins, tropical savannas, and temperate flood plains.
Effect of Reduced Water Table and Fertilizer Levels on Subirrigated Tomato Production
Subirrigated fresh market tomato production in Florida uses raised, plastic-mulched beds and has traditionally used large amounts of water and fertilizer to ensure achieving targeted yield levels.
Peanut and Corn Yield Response to Subirrigation Through an Existing Drainage System
A water control structure was installed in an existing on-farm-drainage system to provide irrigation water by subirrigation. Performance of the water management system was evaluated and the yield
The common leaf-spot of cane fruits in Oregon affects especially the trailing blackberry. Trailing blackberries as used here include Loganberry, Youngberry, Boysenberry, Mammoth, Lucretia, the wild
Root Growth and Water Uptake by Maize Plants in Drying Soil
The roots of plants which were watered well throughout the 18 d experimental period penetrated the soil profile to a depth of 60 cm while the greatest percentage of total root length was between 20-40 cm and high soil water depletion rates corresponded with these high root densities.
Gardens on swamps.
The extent of the raised plots in the Xochimilco-Chalco Basin was much greater in the Aztec period than had been recognized, and archeological evidence has been obtained to substantiate the descriptions left by 1 6th-century chroniclers.
