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 ...
Soil phosphorus extracted by Bray 1 and Mehlich 3 soil tests as affected by the soil/solution ratio in Mollisols
(Taylor, 2011-01)
Different relationships between soil-test methods results have been reported in several agricultural regions. Differences in the same soil-test procedure (e.g., soil/solution ratio) exist between soil-testing laboratories ...
Nutrientes no solo e na solução do solo na citricultura fertirrigada por gotejamento
(2015-01-01)
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 ...
Evaluation of soil extractants for silicon availability for sugarcane
(2018-10-21)
Adequate evaluation and interpretation of silicon (Si) phytoavailability in soil is a key to fertilizer recommendation. This study was conducted to determine the effect of soil texture on the choice of Si extractant, and ...
Assessing the relations among the features of the land cover and of the soil on the soil-water interactions through a functional eco-hydrological indicator
(2019-09-01)
Soil Water Repellency (SWR) is an important ecological property that has implications in the soil and water management and is a useful functional eco-hydrological indicator driven by several natural and human factors. In ...
Scaling to generalize a single solution of Richards' equation for soil water redistribution
(São Paulo - Escola Superior de Agricultura Luiz de Queiroz, 2011)
Using scaling methods, a single solution of Richards' equation (RE) will suffice for numerous specific cases of water flow in unsaturated soils. In this study, a new method is developed to scale RE for the soil water ...
Effects of potassium salinization in the production of fertirrigated red peppers under green houseSalinização por potássio na produção de pimentão fertirrigado sob ambiente protegido
(2019-03-29)
The objective of this study was to evaluate potassium doses in the production of sweet pepper, 'Gaston' cultivar, and effects on soil solution extract, using extractors. The research was installed in the greenhouse of the ...
Invariant Solutions of Richards' Equation for Water Movement in Dissimilar Soils
(SOIL SCI SOC AMERMADISON, 2012)
Scaling methods allow a single solution to Richards' equation (RE) to suffice for numerous specific cases of water flow in unsaturated soils. During the past half-century, many such methods were developed for similar soils. ...
Soil Solution as Affected by Plant Residues and Nitrogen Rates
(Taylor & Francis Inc, 2010-01-01)
Cation mobility in acidic soils with low organic-matter contents depends not only on sorption intensity but also on the solubility of the species present in soil solution. In general, the following leaching gradient is ...
Gypsum application, soil fertility and cotton root growth
(Inst Agronomico, 2019-04-01)
Since there is no consensus on phosphogypsum (PG) rates to be used in agriculture, a better understanding of its effects on the soil solution is needed. Cotton root growth was evaluated as related to Al and Ca activity in ...
