“…SIRI-PRIETO et al (2007) relatam que a não-inversão das camadas de solo durante seu preparo melhora a qualidade deste, aumentando o carbono orgânico, diminuindo a densidade e aumentando a infiltração de água. HU et al (2007) afirmam que a longo prazo o plantio direto aumenta a agregação e a estabilidade dos agregados do solo.…”

“…O preparo do solo com covas grandes para o plantio do maracujazeiro-amarelo é um dos fatores que onera o custo de implantação, exige mão-de-obra (FERREIRA & ARAÚJO NETO, 2007) e pode desestruturar o solo (SIRI-PRIETO et al, 2007). Mesmo assim, a literatura atual recomenda covas entre 0,30 x 0,30 x 0,30m a 0,50 x 0,50 x 0,50m, inclusive em sistema orgânico (SILVA & OLIVEIRA, 2001;PENTEADO, 2004).…”

“…O não-revolvimento do solo e o uso de cultivo mínimo ou plantio direto melhoram a qualidade do solo, o que aumenta o carbono orgânico e a agregação das partículas diminui a densidade e aumenta a infiltração de água (HU et al, 2007;SIRI-PRIETO et al, 2007), fundamental para uma agricultura sustentável. Portanto, esses fatores estão diretamente relacionados a boas produtividades, à sanidade e ao vigor das plantas.…”

“…Releasing cattle to cultivated land for foraging was reported to cause soil compaction (Hamza and Anderson 2005). This affects associated soil physical properties such as BD, infiltration, and porosity (Siri-Prieto et al 2007). It significantly increases soil BD and decreases porosity in the upper soil profile (Binkley et al 2003;Chaichi et al 2005;Curran-Cournane et al 2010) and under similar soil type (Martínez and Zinck 2004;Sharrow 2007).…”

Susceptibility of soil to wind erosion in arid area of the Central Rift Valley of Ethiopia

Background: In Central Rift Valley (CRV) of Ethiopia, renewable land resources are under pressure. Acacia woodland clearance, frequent cultivation, crop residue removal and mono-cropping are among the major land mis-management practices in the area. This has largely been affecting the soil quality. The current study is aimed at assessing the impact of Acacia woodland conversion, and the subsequent mis-managements on selected soil physical properties, and their relation to the prevailing wind erosion in the area. For this study, four land use/land cover types, namely protected woodland (PWL), managed pastureland (MPL), parkland agroforestry (PAF) and treeless cropland (TLCL) were considered. Results: Higher (P < 0.001) macro-aggregates (>0.25 mm) fraction of soil was found under PWL and MPL while higher fraction of micro-aggregates (0.053-0.25 mm) of soil was found under PAF and TLCL. Soil under PAF and TLCL had higher (P < 0.001) proportion of aggregates of < 1 mm, implying potential susceptibility of the soil to wind erosion. Higher soil bulk density (BD) was found in the most top layer (0-15 cm) of TLCL and PAF, and this could be attributed to the trampling effect by animals freely released to these land use types. Conclusion: In the study area, conversion of native woodland to PAF and TLCL and the subsequent mismanagements negatively affected some soil physical properties, thereby enhancing severity of soil erosion by wind. In contrast, although not commonly practiced by smallholder farmers, soil under MPL is more stable and less susceptible to wind erosion.

“…Site-specific subsoiling improves crop production in the United States Coastal Plain soils . Siri-Prieto et al (2007a) compared cotton yield response to several tillage treatments under Alabama rainfed conditions with integration of winter-annual grazing and found that noninversion deep tillage following oat (Avena sativa L.) in a conservation tillage system, provided producers extra income while protecting the soil resource. However, it is unclear how peanut growth and yield will respond to tillage method in a sod-based rotation in the southeast United States.…”

Rotation of row crops with perennial grasses has been shown to improve soil quality characteristics, decrease pest incidence, and increase crop yield. Experiments were conducted in Florida during 2006 and 2007 at Marianna and Quincy to determine effects of termination date and subsequent tillage of established bahiagrass (Paspalum notatum L.) on peanut (Arachis hypogea L.) yield and market grade characteristics when rotating from bahiagrass to a row crop. Treatments included two bahiagrass termination dates (fall vs. spring) and six tillage methods [strip-till (inrow subsoiling), disk plus moldboard plow, disk plus chisel, disk plus paratill plus strip-till, disk, and strip-till with 45 kg N/ha]. Bahiagrass termination timing did not affect soil mechanical resistance, peanut yield or market grade characteristics, including percentages of sound mature kernels, split kernels, other kernels, and hulls. Although significant differences in soil mechanical resistance were detected among tillage treatments, peanut yield did not differ among the tillage methods except for the disk alone in 2007 at Quincy. Strip-till peanut yield did not respond to N application. When pooled over termination timing, peanut yields in strip-till, disk plus moldboard plow, disk plus chisel, disk plus paratill plus strip-till, disk, and strip-till plus 45 N were 4830, 5000, 4810, 4810, 4770, and 4620 kg/ha, respectively. These results indicate that when using perennial grasses in sod-based rotations, farmers have a wide window from fall to spring to terminate bahiagrass for optimum peanut production regardless of tillage system.
