Water Erosion in Oxisols under Coffee Cultivation [PDF]

Revista Brasileira de Ciência do Solo, 2018
ABSTRACT Water erosion is one of the main environmental impacts of land use. When soil and water losses occur, nutrients essential for the growth and maintenance of plants are removed, with harmful outcomes on the sustainability of agriculture and the environment.

STRUCTURAL QUALITY INDICATORS IN COMPACTED OXISOLS GROWN WITH CORN

REVISTA DE AGRICULTURA NEOTROPICAL, 2020
In the face of the elevated cost of economic and environmental order to recover degraded soil, the monitoring of the structural quality of the soil through physical and plant indicators is recommended. This way, this work aimed to verify which parameters may be used together with soil penetration resistance (PR), after compression induced by ...

Drying suppresses fine root production to 1 m depths and alters root traits in four distinct tropical forests. [PDF]

New Phytol
Summary Drying and drought in tropical forests, which have some of the highest net primary productivity on Earth, are likely to alter root dynamics, ecosystem function, and carbon (C) storage. We used a chronic drying experiment in four lowland Panamanian forests to investigate whether soil drying shifts tropical forest root production from surface to ...

Comparison of spatial interpolation techniques to predict soil properties in the colombian piedmont eastern plains

Tecnura, 2017
Context: Interpolating soil properties at field-scale in the Colombian piedmont eastern plains is challenging due to: the highly and complex variable nature of some processes; the effects of the soil; the land use; and the management. While interpolation

Terrain forms and spatial variability of soil properties in an area cultivatedwith citrus Formas do relevo e variabilidade espacial de propriedades do solo em área cultivada com citros

Engenharia Agrícola, 2011
The technique of precision agriculture and soil-landscape allows delimiting areas for localized management, allowing a localized application of agricultural inputs and thereby may contribute to preservation of natural resources.

Potential of Grasses in Phytolith Production in Soils Contaminated with Cadmium

Plants, 2020
Cadmium (Cd) is a very toxic heavy metal occurring in places with anthropogenic activities, making it one of the most important environmental pollutants. Phytoremediation plants are used for recovery of metal-contaminated soils by their ability to absorb

Opal phytolith extraction in oxisols [PDF]

Quaternary International, 2013
The analysis of phytolith assemblages is an important method in studies that uses the soil as an environmental record in order to reconstruct the paleoclimatic conditions. Despite being underused in soil science, this technique is used complementary to the analysis of pollen and other microfossils, as well as to evaluate silicon reserves in the soil ...

Relationships between soil class and nutritional status of coffee plantations Relacionamento entre classes de solo e o estado nutricional de lavouras cafeeiras

Revista Brasileira de Ciência do Solo, 2005
Farm planning requires an assessment of the soil class. Research suggest that the Diagnosis and Recommendation Integrated System (DRIS) has the capacity to evaluate the nutritional status of coffee plantations, regardless of environmental conditions ...

Solubilización de fosfatos por bacterias del género Burkholderia aisladas de oxisoles de la altillanura colombiana

Ciencia y Tecnología Agropecuaria, 2021
Los oxisoles de la altillanura en Colombia contienen hasta 400 mg/kg de fósforo. Sin embargo, la fracción disponible para las plantas es inferior a 3,5 mg/kg, lo que obliga la suplementación con fertilizantes fosfóricos.
