ABSTRACT Bulk density (BD) is a soil physical property used as a soil quality indicator and variations in this measurement influence soil water content and carbon stock estimates. This study aims to compile a database of samples of bulk density, text

Pedotransfer functions (PTF) were developed to estimate the parameters (α, n, θr and θs) of the van Genuchten model (1980) to describe soil water retention curves. The data came from various sources, mainly from studies conducted by universities i

Environmental models often require soil maps to represent the spatial variability of soil attributes. However, mapping soils using conventional in-situ survey protocols is time-consuming and costly. As an alternative, digital soil mapping offers a fa

The growing need for PTFs frequently leads to the use of inadequate PTFs and databases, especially when dealing with data from different regions or climates, such as in tropical and temperate climate zones. Most PTFs have been developed for soils fro

The purpose of this article is to study the existence and uniqueness of quasi-Einstein structures on $3$-dimensional homogeneous Riemannian manifolds. To this end, we use the eight model geometries for 3-dimensional manifolds identified by Thurston.

Em agronomia, modelos de simulação têm sido utilizados como ferramenta de pesquisa, possibilitando organizar o entendimento das respostas das plantas a diferentes ambientes e, consequentemente, predizer a produtividade das culturas. Modelos de cre
