“…Eucalyptus (Cromer et al, 1992). However, eucalyptus does show significant growth increases when grown with irrigation under more arid conditions (Minhas et al, 2015). Had our study been conducted on a more arid site, in finer-textured soil, or used a different water delivery method, we may have seen a positive response to irrigation in loblolly pine.…”

Understanding the processes driving forest productivity is a critical element in our efforts to maximize production of biomass and wood products and more efficiently utilize resources required for plant growth. We examined above and belowground growth and productivity of four tree specieseastern cottonwood (Populus deltoides), American sycamore (Platanus occidentalis), sweetgum (Liquidambar styraciflua), and loblolly pine (Pinus taeda)receiving irrigation and fertilization in the Upper Coastal Plain ecoregion of South Carolina, USA. Trees received treatments throughout an entire intensively-managed harvest rotation, which was nine years for cottonwood and sycamore, and 11 years for sweetgum and loblolly pine. Fertilization and irrigation positively affected growth and productivity of all tree species. Fertilization alone led to increases in stem volume index of up to 329% for cottonwood, 376% for sycamore, 261% for sweetgum, and 49% for loblolly pine. Loblolly pine grew the largest of all species tested, and sweetgum was the largest hardwood. Net primary productivity was driven by leaf and fine root tissue production. When accounting for the effect of tree size, belowground biomass decreased with increasing resource availability in sweetgum and loblolly pine, but not cottonwood or sycamore. These results help explain complex relationships between above and belowground tissues in woody species, and indicate that both ontogeny and resource availability can mediate allocation to belowground tissues.

“…Alguns autores como Minhas et al (2015), observaram esse comportamento em um povoamento de Eucalyptus tereticornis, ao avaliar por 10 anos o efeito da irrigação com águas residuais sobre a produtividade e eficiência no uso da água, e constataram que a irrigação com esgoto promove aumento do volume de madeira, e da eficiência do uso da água, quando comparada à irrigação com a água superficial.…”

Irrigação e fertirrigação no desenvolvimento de eucalipto

O objetivo do trabalho foi avaliar a influência da irrigação localizada e da fertirrigação sobre o desenvolvimento do híbrido de eucalipto Grancam, no quarto ano após a sua implantação. O delineamento experimental foi em blocos casualizados, com parcelas subdivididas. As parcelas foram dois sistemas de irrigação localizada (microaspersão e gotejamento) e um tratamento sem irrigação e, as subparcelas, a adubação convencional e a fertirrigação. Foram avaliados: altura de plantas, diâmetro a altura do peito e volume de madeira. Os resultados foram submetidos à análise de variância e teste Tukey a 5% de significância. A altura das plantas foi 13% maior no sistema gotejamento e 11% no sistema de microaspersão em relação à área sem irrigação. A irrigação promoveu maiores valores de diâmetro a altura do peito, resultando em aumento de 19,8% na produção volumétrica de madeira quando irrigada por microaspersão e 17,7% quando irrigada por gotejamento, em relação à área sem irrigação. A irrigação localizada aumenta a produção volumétrica de madeira para o híbrido Grancam, além disso, quando utilizada a irrigação por gotejamento, há aumento da eficiência do uso da água na produção volumétrica de madeira. A fertirrigação pode substituir a adubação convencional em florestas irrigadas.

“…Some recent studies (Forrester et al ; Hubbard et al ; Kallarackal and Somen ) show similar results, but the overall water use by trees seems to vary greatly, with specific site conditions defining soil type, evaporative demands, stocking density and even the salinity determining actual water use. In a 10‐year study conducted at CSSRI, Karnal, by Minhas et al () Eucalyptus plantation irrigated with sewage performed better than the groundwater. Consumptive water coincided with tree growth rates and increased until the sixth year of planting and stabilized thereafter.…”

Waterlogging and its associated soil salinity are a major impediment to the sustainability of irrigated agriculture. Although conventional engineering drainage technologies such as subsurface or vertical drainage combat the problem, they are costly and generate huge quantities of effluent which is difficult to dispose of. Biodrainage, which removes excess soil water by deep‐rooted fast‐growing trees through evapotranspiration using bioenergy, is an appropriate alternative. Plant consumptive water use varies between 6500 and 28 000 m3 ha‐1 yr‐1 and an ideal tree plantation lowers groundwater tables by 1–2 m over a time period of 3–5 years. Trees such as Eucalyptus, Populus, Casuarina, Dalbergia, Syzigium, Acacia, Prosopis, Leucaena, etc. are found to be effective in lowering shallow groundwater tables and reversing salinity trends. Integration of trees such as Eucalyptus and Populus along with crops in a unified agroforestry system, on approach roads, field bunds or on dykes of ponds in an integrated farming system, is another viable proposition. Irrigation of highly transpiring trees has also been proposed for reuse of wastewater and conservation of nutrient energy into biomass, leading to carbon sequestration, environmental sanitation and eco‐restoration. For effective understanding and implementation, several case studies on the role of biodrainage for managing waterlogging and salinity are discussed in this paper.
