The increase in global demand for food and biofuels, has led to an high demand for agricultural products. That situation implies
an intensification of production systems, and develop strategies to ensure stability against drought, and moreover a better levels
of productivity. Objectives that could be achieved with the irrigation of crops; however, it can promote negative impacts due to
cumulative effects on soil quality, which depend on the chemical composition of the water used. This paper show the results of
a national study of freshwater quality, on 100 river watersheds (up to 100,000 ha), which correspond to a cumulative drainage
area of 70% of country surface. In these freshwaters the following parameters was evaluated: electrical conductivity, concentration
of major cations (Na, K, Ca, Mg), alkalinity, and pH. The results showed Ca, Mg, K, and Na concentrations in ranges of 0.0-
45.1, 0.0-14.1, 0.019-16.8, and 0.78 -139 mg L-1, respectively. The alkalinity was in range of 32 to 420 CaCO3 mg L-1, and this
variable was the most important contribution to get the different values of electrical conductivity of water, which had values
between 71.6 and 1047 micro Siemens cm-1. These features allow propose at least 3 freshwater ecoregions (coastal and
central-south; basalt; Northeast and southeast) at Uruguay, based on the chemical composition of studied freshwaters. Moreover,

development of irrigation, because they have a SAR below 10. MenosThe increase in global demand for food and biofuels, has led to an high demand for agricultural products. That situation implies

Abstract:
Weedy rice (Oryza sativa) is a close relative of domesticated rice and a noxious weed prevalent in rice fields in world regions where rice is grown. Weedy rice management has remained challenging to farmers, mainly due to the weed’s physiological and morphological resemblance to rice cultivars. The introduction of Clearfield rice provides an alternative solution and an additional tool for integrated weed management. Clearfield rice-based programs result in the cleanest rice fields in the southern U.S.
However, persistent application of the imidazolinone herbicides (imazethapyr, imazamox, and imazapic) in Clearfield rice raises concerns about the possible evolution of resistance to ALS-inhibitor herbicides in weedy rice and the transfer of resistance trait. The risk of resistant weedy rice evolution is much higher in Asia, Latin America, and other tropical regions where there is no winterkill and rice is planted at least twice each year. Herbicide carryover to rotational crops is also a concern. We summarized the progress of commercialization of Clearfield rice in 15 countries across the continents of America, Asia and Europe. In some countries, imidazolinone-resistant weedy rice outcrosses have been found abundant, thereby negating the utility of Clearfield technology. The persistence of imidazolinone herbicide residues in the soil is a concern in regions where multiple crops are planted in a year, or the following year. These challenges should be anticipated by countries that are considering adopting Clearfield#1; rice technology. Issues associated with gene escape, resistance evolution in weedy rice, and herbicide carryover to rotational crops remain to be resolved. Research to achieve sustainable solutions for weedy rice management, must be continued and intense educational programs for growers must be sustained. MenosAbstract:
