Chemical properties and enzyme activity in a sewage sludge-treated soil
(Marcel Dekker Inc, 2002-01-01)
A soil sample was taken from the top 0-20cm at Jaboticabal county, São Paulo State, Brazil, air dried, sieved to 5mm, and placed into pots (2700g per pot). Sewage sludge was air-dried, ground to 2mm, and thoroughly mixed ...

An alternative approach for the determination of soil water mobility
(SCIENCE PRESS, 2008)
A new laboratory method was proposed to establish an easily performed standard for the determination of mobile soil water close to real conditions during the infiltration and redistribution of water in a soil. It consisted ...
Bottom-up effects may not reach the top: the influence of ant-aphid interactions on the spread of soil disturbances through trophic chains
(The Royal Society, 2012-06-20)
Soil disturbances that increase nutrient availability may trigger bottom-up cascading effects along trophic chains. However, the strength and sign of these effects may depend on attributes of the interacting species. Here, ...

SPATIAL VARIABILITY OF SOIL PROPERTIES IN AN AGRARIAN REFORM SETTLEMENT
(Soc Brasileira De Ciencia Do Solo, 2015-11-01)
The study of soil chemical and physical properties variability is important for suitable management practices. The aim of this study was to evaluate the spatial variability of soil properties in the Malhada do Meio settlement ...
Soil physical properties and wheat root growth as affected by no-tillage and conventional tillage systems in a Mediterranean environment of Chile
(ELSEVIER SCIENCE BV, 2008-06)
No-tillage systems affect soil properties depending on the soil, climate, and the time since its implementation. In heavy no-tilled
soils a surface compacted layer is commonly found. Such layer can affect root growth and ...

Pedoenvironmental indicators of soil in Western Amazonia, Brazil
(Springer, 2020-12-01)
This study aimed to ascertain what soil attributes may be an indicator of natural and anthropic pedogenic changes in top grassland (TG), low grassland (LG), ecotone zone (EZ), and forest (F) in Western Amazonia. Twenty ...
