Orientação geográfica de estufas de polietileno e potenciais de água no solo no cultivo do melão rendilhado híbrido 'nero'
(2006-01-01)
This study aimed to verify the effects of four different minimum soil watler potentials (-30, -40, -50 e -70 kPa) and two different plastic tunnel positions (North-South and East-West) on net melon yield. The results showed ...

Pedofunctions applied to the least limiting water range to estimate soil water content at specific potentials
(2019-01-01)
The least limiting water range (LLWR) is a soil physical quality indicator that receives much attention. It has been criticized and put to the test regarding mathematical models that compose it since they describe the ...
Low-cost control and measurement circuit for the implementation of single element heat dissipation soil water matric potential sensor based on a SnSe2 thermosensitive resistor
(2021-02-02)
A low-cost signal processing circuit developed to measure and drive a heat dissipation soil matric potential sensor based on a single thermosensitive resistor is demonstrated. The SnSe2 has a high thermal coefficient, from ...
Potenciais de água no solo na produção de alface
(2009-12-03)
The scope of this experiment is to study the influence of soil water potential on lettuce productivity, particularly in relation to deficit and excess of water. Four lettuce cultivars (Americana, Roxa, Crespa and Mimosa), ...

Geotechnology applied to estimate soil loss by water erosion
(2015-01-01)
Water erosion is a major environmental problem that may compromise agricultural areas and the volume of water in a watershed. This paper presents the estimated soil loss in a watershed using Equation Revised Universal Soil ...
Manejo da Irrigação Para Otimização da Produtividade E Qualidade de Frutos de Tomateiro em Sistema de Plantio Direto
(2012-12-01)
There is much information on the adequate soil water matrix potential for returning irrigation in conventional soil tillage systems; however there is not enough information on the best soil water matrix potential for ...
