CHANGES IN SOIL PROPERTIES OF A CITRUS AGROECOSYSTEM INDUCED BY SEASON, AGE OF TREES AND SHEEP GRAZING
The effect of season, age of trees and Pelibuey sheep grazing on physical and chemical soil properties and earthworm populations were evaluated on a regosol eutric soil in Tlapacoyan, Veracruz, México, in a farm with 8 and 16 year-old orange trees (Citrus sinensis L. Osbeck) cv. Valencia during the spring and summer. Continuous sheep grazing during four years did not increase bulk density at 0-40 cm depth, decreased moisture content, increased P and K level, and increased earthworm populations from 85 to 237 individuals m-2. Soil moisture increased during the summer; therefore, electrical conductivity, pH, N, K and Ca were reduced as compared to the spring. The eight years-old plantation showed higher moisture, organic matter, N and P in the soil, but less K and Ca as compared to the 16 year-old one.
