Potential for increasing soil nutrient availability via soil organic matter Improvement using pseudo panel data
(Scientific Research Publishing, 2014-07)
Fixed and random effect models were applied to a pseudo-panel data built of soil analysis reports from tobacco farms to analyze relationships between soil characteristics like soil organic matter (SOM) and soil nitrogen ...
Delineation of management zones with soil apparent electrical conductivity to improve nutrient management
(Elsevier, 2013-11)
Site-specific management demands the identification of subfield regions with homogeneous characteristics (management zones). However, determining subfield areas is difficult because of complex correlations and the spatial ...
Pay it forward: refuse dump from leaf-cutting ants promotes caterpillar digestive performance by increasing plant nitrogen content
(Wiley Blackwell Publishing, Inc, 2019-02-09)
1. The activity of soil-disturbing animals that increase soil nutrients can affect the carbon : nitrogen (C : N) ratio of plants, which, in turn, may determine the transfer of energy and nutrients through higher trophic ...

(Universidad Nacional de Misiones. Facultad de Ciencias Forestales. Instituto Subtropical de Investigación Forestales, 2000-12-01)
Se determinó el contenido de los nutrientes nitrógeno, fósforo, potásio y magnesio en hojas de algarrobo negro (Prosopis nigra, Gris.), medido secuencialmente en ejemplares de buen estado sanitario, ubicados sobre ...
Nutrient Release Dynamics in Argentinean Pampean Soils Amended with Composts under Laboratory Conditions
(MDPI, 2022-03)
Composted manure is the greatest nitrogen (N) source in organic agriculture, where the use of chemical fertilizers, except the use of rock phosphate as P source, is not allowed. The aim of this study was to evaluate the ...
Fine roots of Prosopis flexuosa trees in the field. Plant and soil variables that control their growth and depth distribution
(Springer, 2018-12-15)
Fine root growth in natural vegetation is difficult to predict due to its regulation by soil and plant factors. Field studies in arid ecosystems show a variety of root responses to soil resources and to plant aboveground ...
Biosolid compost amendment increases soil fertility and soybean growth
(Taylor & Francis, 2020-11)
This study evaluates the effect of soil amendment with biosolid compost with wood shavings and yard trimmings on soil fertility, and soybean (Glycine max) biomass, productivity, nutrient uptake, and potential accumulation ...
Propiedades del suelo y productividad de Pinus taeda l. en la mesopotamia argentina
(2014)
Nuestro objetivo fue establecer la vinculación entre algunas características edáficas y el crecimiento de P. taeda, en su zona de plantación comercial en la Mesopotamia Argentina. La ...
Above- and below-ground nutrient tissue concentration and leaf pigment changes in Patagonian woody seedlings grown under light and soil moisture gradients
(Taylor & Francis, 2011-10-28)
To understand the ecophysiology of natural regeneration above- and below-ground nutrient tissue concentration and leaf pigment changes in Nothofagus pumilio (lenga) seedlings grown in three light intensities (4%, 26% and ...
Soil conservation in Polylepis mountain forests of Central Argentina: Is livestock reducing our natural capital?
(Wiley, 2010-06)
Mountain forests and their soils provide ecological services such as maintenance of biodiversity, provision of clean water, carbon capture and forage for livestock rearing, which is one of the principal economic activities ...
