Pedotransfer functions to estimate proctor test parameters under different tillage systems

Revista Brasileira de Ciência do Solo (2010)

Carina Rosa Álvarez Federico Guillermo Micucci Carolina Bustingorri Miguel Ángel Taboada

The Proctor test is time-consuming and requires sampling of several kilograms of soil. Proctor test parameters were predicted in Mollisols, Entisols and Vertisols of the Pampean region of Argentina under different management systems. They were estimated from a minimum number of readily available soil properties (soil texture, total organic C) and management (training data set; n = 73). The results were used to generate a soil compaction susceptibility model, which was subsequently validated using a second group of independent data (test data set; n = 24). Soil maximum bulk density was estimated as follows: Maximum bulk density (Mg m-3) = 1.4756 - 0.00599 total organic C (g kg-1) + 0.0000275 sand (g kg-1) + 0.0539 management. Management was equal to 0 for uncropped and untilled soils and 1 for conventionally tilled soils. The established models predicted the Proctor test parameters reasonably well, based on readily available soil properties. Tillage systems induced changes in the maximum bulk density regardless of total organic matter content or soil texture. The lower maximum apparent bulk density values under no-tillage require a revision of the relative compaction thresholds for different no-tillage crops.

Soybean growth under stable versus peak salinity

Scientia Agricola (2011)

Carolina Bustingorri Raúl S. Lavado

The production of soybean (Glycine max L.) has doubled in the last two decades. It is now being grown on both traditional arable lands and on marginal soils, including saline soils, in various parts of the world. Most research on crop tolerance to salinity has been performed using soils with stable levels of salinity. However, there are soils that undergo sudden increases in topsoil salinity for short periods of time. The aim of this study was to compare the effect of stable salinity concentrations with peaks of salinity for their effects on soybean vegetative growth, grain yield, and the accumulation of chlorides. The response of soybean growth was evaluated in pot experiments with the following treatments: Control (non saline soil), soil salinity level of 0.4 S m-1 (0.4S) or 0.8 S m-1 (0.8S), and soil subjected to salinity peaks of 0.4 S m-1 (0.4P) and 0.8 S m-1 (0.8P). The salinity levels were obtained by application of saline irrigation water. Soybean responded differently to stable salinity levels versus peaks of salinity. When salinity was a permanent stress factor, regardless of the salinity level (i.e. 0.4 and 0.8 S m-1), biomass production and differentiation of reproductive organs was greatly affected. For 0.8S treated plants, they never reached the reproductive phase. Conversely, only small differences in growth data were found between 0.4P and Control treatments, although an 80% decrease in yield was associated with the 0.4P treatment. To obtain a reasonable soybean yield, a leaf chloride concentration of 1 mg g-1 of Cl- in dry matter should be considered a maximum threshold.

Protective effect exerted by soil phosphorus on soybean subjected to arsenic and fluoride

Redox Report (2017)

Carolina Bustingorri Guillermo O. Noriega Raúl S. Lavado Karina Balestrasse

Objetive: Arsenic (As) and fluoride (F) are found in groundwater and soils around the world, causing different problems to crops. Because these elements compete against phosphorus (P) in soils and plants, their relationship is complex. The aim of this work was to study the oxidative stress of soybean plants subjected to different concentrations of As and F, and the effect of P.Methods: The following 10 treatments were carried out in each of two soils with different P content: three As levels (low 10 mg As kg-1, medium 50 mg As kg−1 and high 100 mg As kg−1), three F levels (low 160 mg F kg−1, medium 250 mg F kg−1 and high 500 mg F kg−1) and three As + F levels (same concentrations), and the control treatment (soil with the background As and F concentrations) Lipid peroxidation, chlorophyll, gluthatione contents and antioxidant enzymes activities were determination.Results: Increased lipid peroxidation and alterations in glutathione content, catalase, superoxide dismutase and peroxidase activities as well as in chlorophyll content revealed that As causes higher oxidative stress in plants grown in soils with low P content.Conclusion: Stress parameters in F treatments were less affected. Plants grown in soils enriched with P revealed a decrease in the toxic effects caused by As and F.

SOYBEAN RESPONSE AND ION ACCUMULATION UNDER SPRINKLER IRRIGATION WITH SODIUM-RICH SALINE WATER

Journal of Plant Nutrition (2013)

Carolina Bustingorri Raúl S. Lavado

The magnitude of crop growth and yield depends on the salinity level, the toxic ions present, and the irrigation system used. In order to study the effect of saline sprinkler irrigation on soybean growth and ionic accumulation in plant tissues a pot experiment was set up. There were three irrigation water quality treatments [electrical conductivity (EC) 0, 2, and 4 dS m−1]. Soybean aerial biomass was 25% lower than the Control when irrigation salinity was 4 dS m−1. Clearly salinity entering via leaves affected the grain filling stage and severely reduced soybean grain production (80% reduction) when salinity in irrigation water surpassed 2 dS m−1. Sprinkler irrigation aggravates soybean's low salinity tolerance and restricts its cropping in such conditions. For early stages two linear relationships between leaf chloride (Cl−) concentration (Y = 14.2–2x) or potassium (K+)/ sodium (Na+) ratio (Y = 5.3x−3.4) and soybean grain yield were found. Both relationships may be used as diagnostic tools for soybean growing under saline sprinkler irrigation.

Descompactación de suelos en siembra directa: efectos sobre las propiedades físicas y el cultivo de maíz

Ciencia del suelo (2006)

Carina Rosa Álvarez Miguel Ángel Taboada Carolina Bustingorri Flavio H. Gutiérrez Boem

No-tilled soils have higher penetration resistances and bulk density values than tilled soils. Shallow compaction may be alleviated using deep tillage practices. The objectives of this study were to determine the effects of soil alleviation on: 1- soil physical properties at maize sowing and harvest, 2- root abundance, maize yield and its components. Three experiments were conducted during the 2004/05 growing season. The experiments had a complete block design, with 2 treatments (control and deep-tilled) and 3 replicates, and were located at Junin, San Gregorio and Chivilcoy. Soil bulk density, soil water content, soil penetration resistance and infiltration rate were determined at maize sowing and harvest. At flowering maize root abundance, intercepted photosynthetic active radiation and leaf greenness were determined. Additionally, yield and its components were measured. Soil alleviation increased infiltration rate at sowing (P<0,05), but there were no differences at harvest. Soil alleviation reduced penetration resistances at sowing by 54%, 28%, 42 % at Junin, San Gregorio and Chivilcoy, respectively (P<0,05). Deep tillage increased root abundance at flowering at Junin and Chivilcoy (P<0,05). Maize yield showed a positive and statistically significant increase with soil alleviation. However, its magnitude was only 6,5% more than control yield. This result was in accordance with a 3% increase in intercepted photosynthetic active radiation. Yield response to subsoiling was positively related with the original soil bulk density at each site. Although the measured changes might improve water use efficiency, little impact on yield was observed due to a relatively humid cropping season. More research is needed in order to establish crop response in a wide range of water availability and soil compaction conditions.
