TILLAGE EFFECT ON SOIL ORGANIC MATTER, MYCORRHIZAL HYPHAE AND AGGREGATES IN A MEDITERRANEAN AGROECOSYSTEM
(Sociedad Chilena de la Ciencia del Suelo, 2010)
Estimating soil organic carbon in Mollisols and its particle-size fractions by loss-on-ignition in the semiarid and semihumid Argentinean Pampas
(Elsevier B.V., 2018-03)
Recent interest in soil quality assessment underscores the need for an accurate measurement of soil organic carbon (OC) and its labile fraction, i.e. particulate OC. The loss-on-ignition (LOI) method has been proposed as ...
Effect of indigenous mycorrhizal colonization on phosphorus-acquisition efficiency in soybean and sunflower
(Wiley VCH Verlag, 2011-08)
Despite a general consent about the beneficial contribution of arbuscular mycorrhizal fungi (AMF) on natural ecosystems, there is an intense debate about their role in agricultural systems. In this work, soybean (Glycine ...
Soil physical quality of mollisols quantified by a global index
(Universidade de São Paulo, 2015-03)
Indicators synthesizing the state of the structural quality and the function of the porous system are useful for assessing soil production capacity as well as the way it may serve natural ecosystems. This research aimed ...
Contribution of nitrogen mineralization indices, labile organic matter and soil properties in predicting nitrogen mineralization
(Sociedad Chilena de la Ciencia del Suelo, 2018-03)
The objectives of this study were i) to measure the nitrogen (N) mineralization potential; ii) to evaluate N mineralization indices and labile soil organic matter (SOM) fractions, and iii) to analyze their interrelationship ...
Conservation of ecosystem services in Argiudolls of Argentina
(MDPI, 2020-12-19)
Mollisols are a fundamental component of global agricultural production. In the Argentine Pampas region, 65% of the Mollisols belong to Argiudoll great group. These soils have an agricultural aptitude, with limitations ...
DTPA-extractable zinc threshold for wheat grain yield response to zinc fertilization in Mollisols
(Soil Science Society of America, 2021-09)
Determining soil Zn thresholds for wheat (Triticum aestivum L.) is still challenging because soil Zn tests have been poorly calibrated. Therefore, this work aimed to determine, under field conditions, the diethylenetriam ...
