-Rural communities located in the Brazilian Northeast, especially in the semiarid zone, live with water shortages resulting from erratic rainfall. This work proposes the cultivation of saltbush (Atriplex nummularia) in the Rural Settlement Project of Boa Fé, Mossoró/RN as alternative to the disposal of reject brine from desalination plant on yield of forage. The statistical design was a split-plot design, being four treatments at the plots, related to irrigation with reject brine water, at different levels of soil moisture by moisture from Field Capacity (FC) (100, 85, 70 and 50% of FC) and in subplots and two levels of organic manure (without fertilized and fertilized) with four replications. The variables of yield and forage quality of saltbush were analyzed. It was observed that saltbush has a great production capacity in terms of fresh matter and drought for saltbush under a level of 85% soil moisture in relation to the field capacity of soil, presenting minimal loss of yield; however, this proved to be productive even with the dry soil. The total yield was satisfactory, showing its viability for forage production.Keywords: Atriplex nummularia. Water reuse. Salinity.PRODUÇÃO E QUALIDADE FORRAGEIRA DA ERVA SAL IRRIGADA COM REJEITO DA DESSALINIZAÇÃO POR OSMOSE REVERSA RESUMO -As comunidades rurais situadas no Nordeste brasileiro, em especial na região semiárida, convivem com a escassez de água resultante da irregularidade das chuvas nesta região. O presente trabalho propôs cultivar a erva sal (Atriplex nummularia) no Projeto de assentamento Rural Boa Fé, Mossoró/RN como alternativa à deposição do rejeito salino para a produção de forragem. O delineamento estatístico foi parcelas subdivididas, sendo quatro tratamentos nas parcelas, referentes a irrigação com rejeito salino em diferentes níveis de umidade do solo tendo como base a umidade na Capacidade de Campo (CC) (100, 85, 70 e 50% da CC) e nas subparcelas, dois níveis de adubação orgânica (não adubado e adubado), com quatro repetições. Foram analisadas variáveis de produção e qualidade da forragem da erva sal. Observou-se que, a erva sal possui boa capacidade de produção de matéria fresca e seca sob um nível de 85% de umidade do solo em relação à sua capacidade de campo, apresentando mínimas perdas de rendimento, porém, mostrou-se produtiva mesmo com o solo mais seco. A produtividade total foi satisfatória mostrando sua viabilidade para a produção de forragem.Palavras-chave: Atriplex nummularia. Reuso de água. Salinidade.

“…A. nummularia has been selected due its high growth rate and palatability for livestock. Reported yields range from 11 t ha À1 (Benjamin et al, 1995) ) and produced 15.6 t ha À1 biomass from four successive total harvests (Watson & O'Leary, 1993). The performance of species in field trials result from a range of soil and climatic conditions and management scenarios and these need to be taken into account in the development of regional or global estimates.…”

Bio‐mitigation of carbon following afforestation of abandoned salinized farmland

2011

As the global demand for food continues to increase, the displacement of food production by using agricultural land for carbon mitigation, via either carbon sequestration, bioenergy or biofuel is a concern. An alternative approach is to target abandoned salinized farmland for mitigation purposes. Australia, for example, has 17 million ha of farmland that is already or could become saline. At a representative, salinized, low rainfall (350 mm yr À1 ) site at Wickepin, Western Australia, we demonstrate that afforestation can mitigate carbon emissions through either providing a feedstock for bioenergy or second generation biofuel production and produce salt-tolerant fodder for livestock. A range of factors markedly affect this mitigation. These include hydrological conditions such as salinity, site factors such as slope position and soil properties and a range of silvicultural factors such as species, planting density and age of the planting. High density (2000 stems ha À1 ) plantings of Eucalyptus occidentalis Endl. produced a mean total biomass of 4.6 t ha À1 yr À1 (8.5 t CO 2 -e ha À1 yr À1 ) averaged over 8 years. Atriplex nummularia Lindl. produced a mean total biomass of 3.8 t ha À1 yr À1 (6.9 t CO 2 -e ha À1 yr À1 ) averaged over 4 years and approximately 1.9 t ha À1 yr À1 of edible dry matter annually to 8 years of age. With differences in salt tolerance between E. occidentalis and A. nummularia, we propose an integrated approach to treating salinized sites that takes salinity gradients into account, replicates natural wetland ecosystems and produces both fodder and biomass. Continued mitigation is expected as the stands mature, assuming that growth is not affected by the accumulation of salt in the soil profile. Such carbon mitigation could potentially be applied to salinized farmland globally, and this could thus represent a major contribution to global carbon mitigation without competing with food production.

“…A. lentiformis is native to the Mojave Desert and other southwestern U.S. deserts (Blank et al, 1998), where it provides valuable habitat and forage for native wildlife and livestock (Meyer, 2005). It can support high rates of net annual productivity and ET if water is available (Glenn and O'Leary, 1985;Watson et al, 1987;Watson and O'Leary, 1993;Steinwand et al, 2001). In the Owens Valley, California, it has a normal rooting depth of 3 m but the roots can extend to 5 m to reach the water table (Elmore et al, 1997).…”
