The practice of eliminating the vegetal cover of citrus orchards in Concordia (Entre Ríos) contributes to the degradation of the physical, chemical, and biological properties of the soil. The objective of this study was to evaluate the effects of utilizing different mulches on soil moisture and temperature, water status of the crop, incidence of weeds, and growth of a Nova mandarin orchard. This experiment was conducted in campaigns 2012/2013 and 2013/2014. The seven experimental treatments were: control; conventional chemical management; 6 and 12 centimeters thick rice husk mulch; 6 and 12 centimeters thick eucalyptus wood chip mulch; and plastic cover mulch of 250 microns thick. During spring and summer, the volumetric moisture of the soil increased between 16 and 96% with the use of the mulches (approximately 10 centimeters), with the largest increases observed in soil with eucalyptus wood chip mulches. The organic mulches decreased soil temperature up to a depth of 15 centimeters, achieving the lowest surface temperatures (0-5 centimeters), whereas the plastic cover mulch had temperatures values in between those of the conventional chemical management and the organic mulches. In periods of water deficit, the stem water potential was higher for the eucalyptus wood chip mulches and the rice husk mulch of 12 centimeters thick. The eucalyptus wood chip mulches and the plastic cover showed the best weed control. Additionally, the evaluated mulches increased the growth of stem and treetop diameters by 29 and 47% respectively.
