ABSTRACT Soil erosion in tropical environments causes environmental, social and economic damage. Canephora coffee crops are impacted by soil erosion and testing alternatives to mitigate this damage is a current need. This study aimed to evaluate the losses of sediment, organic carbon, nutrients and surface runoff caused by water erosion in between-rows spacing of Coffea canephora Pierre ex A. Froehner plants in management with and without cover crops, and the effect of the intensity of rains on sediment loss and […]

ABSTRACT Improper management of rangelands can cause land degradation and reduce the economic efficiency of livestock activity. The aim of this study was to evaluate soil properties and quantify plant biomass production in four natural rangeland management systems in the Santa Catarina Plateau (Planalto Catarinense) of Brazil. The treatments, which included mowed natural rangeland (NR), burned natural rangeland (BR), natural rangeland improved through the introduction of plant species after harrowing (IH), and natural rangeland improved through the introduction of plant […]

An experiment was carried out at the Bebedouro Experimental Station in Petrolina, state of Pernambuco, from January 1999 to December 2001, on a sandy Yellow Eutrophic Argisol, with the objective of evaluating the effect of green fertilizers associated with liming and mineral and organic fertilization on the soil chemical attributes and the yield and quality of irrigated melon (Cucumis melo). A randomized complete block design with split-plots and four replications was used. The treatments assigned to the main plots were […]
