The study evaluates and compares two procedures for selecting soil quality indicators (used the construction of indices, SQI) by using diverse chemical, physical, biological properties, role microbiological properties in SQI. Different environments were selected from an extensive agricultural production site rolling pampa, Buenos Aires, Argentina. plots included undisturbed soil, a grassland continuous tilled soils with four different surface horizon depths (25, 23, 19, 14 cm). Various...
While concerns about greenhouse gas (GHG) emissions and animal welfare persist, livestock farming offers unique ecosystem services. In Argentina, where significantly contributes to GHG emissions, particularly enteric methane (CH4), urgent action is required develop effective mitigation strategies while maintaining performance. This study assesses the potential of inclusion Lotus tenuis in natural grasslands mitigate CH4 improve forage quality Salado River basin, Argentina. Twenty-four beef...
Site preparation practices used during establishment of second rotation Pinus plantations on the coastal lowlands south-east Queensland became more conservative 1990s. Traditionally, site included stick raking residue into windrows, followed by burning. Areas subject to periodic saturation were then cultivated form continuous high mounds, while better drained sites contour strip cultivated. These replaced retention biomass hillslopes. Similarly, intensive disturbance was increasingly tillage...
A rainfall simulator and overland flow study was conducted to determine in situ eroded sediment size distributions for a range of forest road surfaces at 2 important commercial plantation centres subtropical south-east Queensland, Australia; parameters necessary running the CREAMS model assess erosion transport from road/table drain systems. Results revealed very low concentrations fine particles surface gravel roads, somewhat higher proportions ungravelled (dirt) surfaces. However, there...
A field study of sediment movement through vegetative barriers was carried out to assess the sediment-trapping effectiveness barrier types typically used in forest plantation management south-east Queensland, Australia, and develop a simple methodology for predicting these barriers. For sites at centre Queensland's 110 000 ha Pinus 45 Araucaria program, small flumes (plots) were established on range vegetation slope gradients, sediment-laden flows passed them. Sediment trapping plots...
One of the expected benefits no-tillage systems is a higher rate soil C sequestration. However, retention in not always apparent when applied, due e.g., to substantial differences type and initial content. The main purpose this study was evaluate potential management increase stock total organic soils Pampas region Argentina. Forty crop fields under conventional tillage seven undisturbed were sampled. Total C, N, their fractions stratification ratios storage capacity different managements...
South America covers a vast area with diverse climates and landscapes, high participation in the global production of food fibers. It is crucial to understand risks, vulnerabilities, opportunities that climate change brings this region. We analyzed increasing tension between agribusiness models smallholder models, opportunities, main adaptation measures can be adopted agricultural sector American countries facing change. This study review [...]
Abstract Microbial properties may help to provide an integrated view of changes in soil functioning associated with management or status. The fatty acid profiles membrane phospholipids ( PLFA ) can give the composition ecophysiological groups microbial communities, while catabolic response CRP estimate heterotrophic functional diversity soils, both relevant understanding role micro‐organisms soil. objectives this study were (i) evaluate and as tools characterize (ii) clarify relation among...
The studies reported in this paper were designed to evaluate the potential for disposal of sewage sludge commercial Pinus plantations at Beerburrum, 50 km north Brisbane. Soil descriptions and measurements hydraulic properties made three soils, covering range perceived site suitability application. Disc permeameters a rainfall simulator used characterize surface infiltration both with without sludge, ponded rings assess permeability upper B horizon. Although conductivities potentially high,...
Summary In Queensland, comprehensive site capability information is used to guide planning for Pinus plantation establishment. Prior dealing establishment, field surveys are provide suitability and assessment. Knowledge of as an input into selection preparation systems, design, taxon fertilizer prescription. The collected in, the knowledge inferred from, described in this paper.
Soil is a non-renewable natural resource, considered as the basis for food production. Changes in soil properties may indicate potentially beneficial or degradative effects of given management practice, so it important to select most sensitive act quality indicators. This research evaluated different approaches selecting indicators construction indices (SQIs). The sensitivity integrative SQIs, constructed by considering diverse chemical, physical, and biological properties, was compared with...
Bulk density is commonly measured in compaction, cultivation, land evaluation and site classification studies forestry. Typically, measurements are made using a small-diameter core sampler (an integral open drive sampler) which manually driven into the soil profile. The study reported this paper was designed to determine effects of size on bulk estimates, identify optimal sampling intensities for coastal lowlands south-east Queensland. Four sizes were tested (internal diameters 3.48, 4.83,...
This paper reports a study of the potential for off-site movements pollutants from sewage sludge broadcast onto soil surface in Pinus plantations established on coastal lowlands south-east Queensland. Laboratory studies size and settling velocity distributions rainfall-wetted showed that it is relatively coarse non-erodible. Field rainfall simulation at three sites pine forests near Beerburrum found no significant increase interrill erosion due to broadcasting sludge. (Most or all sediment...
Summary This paper examines continuing developments in inter-rotation management of steep-country Araucaria cunninghamii (hoop pine) plantations south-east Queensland, Australia. Current systems for clearfell residue and understorey vegetation during second rotation site preparation are described, their deficiencies briefly outlined. A number options retaining on hillslopes presented, potential use forestry, based preliminary trials, is assessed.
