Concentration of injetion solution and its effects on soil and on yield of fertirrigated banana cv. Terra Maranhão
Provedor de dados: 70
Autores: Coelho,Eugênio F.; Andrade Neto,Torquato M. de; Barros,Damiana L.
The Fertigation is the combined application of water and nutrients to a crop. It can be adapted to all types of agricultural crops. The objective of this study was to evaluate the effect of urea concentration in irrigation water on electrical conductivity of the soil solution and saturation extract along the first cycle of banana cv. Terra Maranhão. The experiment followed a completely randomized design with six treatments and ten replications. Treatments regarded for using three urea concentrations (1.0; 2.5 and 4.0 g L-1) in irrigation water applied by two micro irrigation systems (microsprinkler and drip). Results showed that there was a linear elevation of electrical conductivity of saturation extract and soil solution with the increase on...

Potassium estimation in the soil solution based on electrical conductivity and soil water content
Provedor de dados: 91
Autores: Andrade Neto,Torquato M. de; Coelho,Eugênio F.; Santana,José A. do V.; Santana Júnior,Edvaldo B.; Alves,Márcio da S.
The objective of this work was to evaluate and to validate models for estimating potassium in the soil solution as a function of bulk electrical conductivity (ECw), soil water content (q) and a soil solution electrical conductivity (ECss). Treatments consisted of using three concentrations of injecting solution of potassium chloride (1.0, 2.5 and 4.0 g L-1) which were applied by two trickle irrigation systems (microsprinkler and drip) during the first cycle of the banana crop cv. Terra Maranhão. Results showed that it is feasible to estimate potassium concentration in the soil solution from data of ECss and q obtained by time domain reflectometry (TDR) using an equation that combined a linear and a potential model. The estimated values of potassium...
