Estudo da salinidade do solo na machamba da ESUDER – Pambarra - distrito de Vilankulo

Abstract

The present study was carried out on the banks of the Govuro River with a water table that varied between (80 - 100)cm deep. The objective of the research was to improve the salinity of the soil in order to reduce the salinity of the soil for a favorable crop production. A randomized complete block design was used consisting of three (3) (80 - 100)cm consisted of three (3) treatments and five (5) blocks for a total of 15 plots where the treatments were (50, 100 and 200) % of irrigation recommended by the standard model model of salinity control, and applied 1.3 ton/ha. For the diagnosis of the effect of the treatments applied, 7 samples were taken, the first and the second were collected before were collected before the application of the treatments. The study consisted of collecting samples in the field, followed by field, followed by determinations of electrical conductivity. Humidity was measured in the The soil was moderately saline, and the moisture level was measured in the laboratory of the Chibuene Teacher Training Institute (IFP). moderately saline, and the level of salts decreases with increasing depth, although in some The level of salts in the soil depended on the amount of water to be adopted. The level of salts in the soil depended on the amount of water to be adopted. The treatments contributed significantly in minimizing soil salts. The level of salts in the soil depended on the amount of water to be adopted. The water level corresponding to 200% had the greatest effect on the reduction of salts. There were no significant differences in moisture in all treatments except at (20 - 40) cm depth where there was more moisture and with more irrigation specifically in the last sample.
