Bulk Density Prediction for Histosols and Soil Horizons with High Organic Matter Content

Sidinei Julio Beutler, Marcos Gervasio Pereira, Wagner de Souza Tassinari, Michele Duarte de Menezes, Gustavo Souza Valladares, Lúcia Helena Cunha dos Anjos


ABSTRACT Bulk density (Bd) can easily be predicted from other data using pedotransfer functions (PTF). The present study developed two PTFs (PTF1 and PTF2) for Bd prediction in Brazilian organic soils and horizons and compared their performance with nine previously published equations. Samples of 280 organic soil horizons used to develop PTFs and containing at least 80 g kg-1 total carbon content (TOC) were obtained from different regions of Brazil. The multiple linear stepwise regression technique was applied to validate […]

Oxidizable organic carbon fractions of an ultisol under an alley cropping system

The input of organic matter to the soil by legumes in alley cropping systems may be an alternative for a sustainable soil use in the humid tropics. The objective of this study was to compare the input of oxidizable organic matter in a combination of residues from different legumes in alley cropping systems on an Ultisol. Two legume species were evaluated: leucena (Leucaena leucocephala) and pigeon pea (Cajanus cajan), which have high-quality residues, and Philippine pigeonwings (Clitoria fairchildiana) and acacia […]
