ABSTRACT Soil salinity is a major abiotic stress on plant growth in coastal saline soil. The objective of this study was to screen the optimal combination of organic materials with beneficial bacteria for application under real field conditions to improve coastal saline soil. A two-factor pot experiment was carried out with corn in coastal saline soil for 26 days. In the naturally aerobic environment, a split-plot experiment was conducted with different rates of organic materials (organic fertilizer and mushroom residue) […]

Wastewater application to soil is an alternative for fertilization and water reuse. However, particular care must be taken with this practice, since successive wastewater applications can cause soil salinization. Time-domain reflectometry (TDR) allows for the simultaneous and continuous monitoring of both soil water content and apparent electrical conductivity and thus for the indirect measurement of the electrical conductivity of the soil solution. This study aimed to evaluate the suitability of TDR for the indirect determination of the electrical conductivity (ECse) […]

Nitrogen and potassium applications affected the nutrient concentration and accumulation of sweet pepper, cultivar Mayata, grown in a protected environment. An experiment was conducted in a protected environment in Eutrostox, during 34 weeks from November, 1996 to August, 1997, with the following treatments: control and combination of three rates of N (13.3; 26.6 and 39.9 g m-2) and three rates of K (5.5; 11.0 and 16.6 g m-2). All plants were watered by trickle irrigation and the urea and KCl […]
