ABSTRACT Microorganisms have a fundamental importance in agricultural ecosystems and may be influenced by several factors, including soil management. The aim of this study was to evaluate the effects of cropping systems and soil covers on the microbial community in soil cultivated with muskmelon (Cucumis melo L.). The experiment was conducted in a randomized complete block design with four replications. The treatments were arranged in a split plot design with cropping systems (no-tillage and conventional tillage systems) assigned to the […]

The present study aimed at characterizing the main soil types under melon crop in the Apodi Tableland, state of Rio Grande do Norte. This investigation focused on the mineralogical soil features as an attempt to generate information for adequate soil and crop management. Three soil types were selected: Typic Haplocambids, Typic Eutrotorrox and Arenic Kandiustults. The mineralogy of sand, silt and clay fractions was evaluated through X ray diffraction analyses and scanning electron microscopy in complementary, undisturbed samples. The mineralogical […]
