SOIL AND SOIL SOLUTION NUTRIENT CONTENT IN DRIP FERTIGATED CITRUS
(Soc Brasil Engenharia Agricola, 2015-05-01)
Soil solution analysis has shown to be a promising method for soil fertility diagnosis, mainly in fertigation systems. The objective of this study was to evaluate the behavior of nutrients in soil and soil solution by ...
Plant nutrients in a degraded soil treated with water treatment sludge and cultivated with grasses and leguminous plants
The objective of this work was to evaluate rates for applications of water treatment sludge (WTS) as a nutrient source for grasses and leguminous plants cropped in a soil degraded by tin mining in the Amazon Region (Natural ...

SOIL NUTRIENT CONTENTS AND ENZYMATIC CHARACTERISTICS AS AFFECTED BY 7-YEAR NO TILLAGE UNDER MAIZE CROPPING IN A MEADOW BROWN SOIL
(Sociedad Chilena de la Ciencia del Suelo, 2010)
Influence of Agroforestry and Traditional Management of Maize (Zea mays L.) on Soil Fertility
The aim of the work was to evaluate soil nutrient concentration at 0-5, 5-10, and 10-20 cm in maize (Zea mays L.) grown in sequence with black oats (Avena strigosa Schreb.) under Leucaena diversifolia alley cropping ...
Soil and leaf nutrient content of tree species support deciduous forests on limestone outcrops as a eutrophic ecosystem
(Sociedade Botânica do Brasil, 2015-06-01)
The leaf and soil nutrient status of plants has been used to infer structural and functional aspects at the ecosystem level. Such data are available for tropical and savanna systems growing on poor and acidic soils; however, ...
Micronutrient contents in the profile of a recovered soil with sewage sludge and native species of Atlantic Forest
The use of sewage sludge in agriculture and recovery of degraded areas has been shown as a promising alternative for its final destination. Studies on micronutrient levels after sludge application are necessary to avoid ...
Release of nutrients and organic carbon in different soil types from hydrochar obtained using sugarcane bagasse and vinasse
Hydrothermal carbonization of byproducts from the sugarcane industry generates a solid material (hydrochar) rich in carbon and nutrients with the potential to be used as a soil conditioner. In this context, the objective ...
