Effects of physicochemical soil properties of five agricultural soils on herbicide soil adsorption and leaching
(Pontificia Universidad Católica de Chile. Facultad de Agronomía e Ingeniería Forestal, 2011)
EFFECT OF NITROGEN FERTILIZATION ON YIELD AND QUALITY OF WATERMELON, CV. TOP GUN
(Univ Fed Rural Semi-arido-ufersa, 2017-01-01)
Nitrogen (N) is the second most important nutrient required by watermelons that can limit their growth and affect fruit quality when deficient. We evaluated the soil (N-nitrate) and foliar N contents and soluble-solid ...
Mass spectrometry of organic matter influenced by long-term pedogenesis and a short-term reclamation practice in an Oxisol of Brazil
(Agricultural Inst Canada, 2016-03-01)
Little is known about the influence of soil pedogenesis and reclamation practices on the chemical composition of soil organic matter (SOM) in eroded Oxisol. We examined the long-term influence of pedogenesis and 8 years ...
The effects of land management (grazing intensity) vs. the effects of topography, soil properties, vegetation type, and climate on soil carbon concentration in Southern Patagonia
(Academic Press Ltd - Elsevier Science Ltd, 2016-08)
Grazing is an economically important activity in Southern Patagonia?s steppe and woodland ecosystems. In the past, emphasis has been on maximizing the provisioning capacity of these ecosystems with little concern for the ...
Quantifying soil compaction in persimmon orchards using isum (Improved stock unearthing method) and core sampling methods
(2020-07-01)
Agricultural activities induce micro-topographical changes, soil compaction and structural changes due to soil cultivation, which directly affect ecosystem services. However, little is known about how these soil structural ...

Factors affecting Hg (II) adsorption in soils from the Rio Negro basin (Amazon)
(Sociedade Brasileira de Química, 2005-06-01)
Mercury (II) adsorption studies in top soils (top 10 cm) from the Rio Negro basin show this process depends strongly on some selected parameters of the aqueous phase in contact with the soils. Maximum adsorption occurred ...
