Effects of soil management systems on soil microbial activity, bulk density and chemical properties
(Empresa Brasileira de Pesquisa Agropecuária (EMBRAPA), 2001-12-01)
Este trabalho teve por objetivo estudar os efeitos de diferentes sistemas de uso e manejo na densidade do solo nas suas propriedades químicas e na atividade microbiana em um Latossolo Vermelho distrófico (Oxisol). As ...
Use of compost from olive oil by-products as soil amendment: effect on physical and chemical properties of loamy-sand soils
(ISHS, 2014-10-30)
Compost obtained from olive oil by-products are usually characterized byhigh potassium (K) and phosphorous (P) content as well as moderate to high electrical conductivity (EC) levels. Amending soils with compost may represent ...
Light acidification in N-fertilized loess soils along a climosequence affected chemical and mineralogical properties in the short-term
(Elsevier, 2016-04)
Some evidences indicate that N-fertilization of crops decreased pH values of loess soils of the Argentinean Pampas in the last decades. We analyzed the A-horizons of four N-fertilized (F) and non-fertilized (NF) paired ...

Impact of cattle grazing on temperate coastal salt marsh soils
(Wiley, 2015-06)
Over the last two decades, grazing intensity has increased in the temperate salt marshes of Samborombón Bay (Argentina) due to agricultural expansion and the displacement of domestic livestock to these areas. We investigated ...

Soybean fungal soil-borne diseases: a parameter for measuring the effect of agricultural intensification on soil health
(2014)
The aim of this study was to investigate the influence of agricultural intensification on soil microbial diversity, chemical and physical parameters, and the decrease of the incidence of sudden death syndrome (Fusarium ...
Adsorption and transport of imazapyr through intact soil columns taken from two soils under two tillage systems
(2015)
The objective of this work was to study the sorption and transport of imazapyr (IMZ) in two soils with different physical–chemical properties, subject to long-term conventional tillage (CT) and no-tillage (NT) systems. ...
Soil physical properties under different cattle stocking rates on Mollisols in the Buenos Aires Province, Argentina
(2018-09)
This study evaluated the impact of different cattle stocking rates on different soil physical properties in different soils in an integrated livestock no-till agricultural system. We evaluated three stocking rates ...
