Transpiration of young cocoa trees under soil water restriction

Scientia Agricola, 2020
: Cocoa plantations in Brazil have been expanding beyond the borders of traditional regions by implementing a strategy based on irrigation and the establishment of crops exposed to full sunlight.

Transpiration response of palmer amaranth (Amaranthus palmeri) to drying soil in greenhouse conditions

Frontiers in Agronomy, 2022
Palmer amaranth (Amaranthus palmeri S. Watson) is a troublesome weed that can result in substantial crop yield loss in irrigated and rainfed agricultural systems of the U.S. Great Plains.

Impact of Irrigation Scheduling on Corn Yield and Water Balance in Sandy Soils of Central Minnesota Using the EPIC Model.

Irrigation and Drainage, EarlyView.
ABSTRACT Efficient irrigation scheduling is critical in sandy soils to achieve optimum yield and maximum net benefit with minimum environmental concerns. The Environmental Policy Integrated Climate (EPIC) model was used to study the impacts of autoirrigation of corn on crop yield and soil water balance during 2019–2021 at −300 and −450 kPa for loamy ...

Real Time Soil Moisture (RTSM) Based Irrigation Scheduling to Improve Yield and Water-Use Efficiency of Green Pea (Pisum sativum L.) Grown in North India

Agronomy, 2022
A field experiment on green pea (Pisum Sativum L.) was conducted under drip irrigation to determine the irrigation schedule based on real-time soil moisture measurements with irrigation treatments (main plots) and fertilizer treatments (sub-plots) in a ...

A Coupled AquaCrop–Richards Model for Improved Crop Yield Prediction Through Physically Based Soil Water Dynamics

Irrigation and Drainage, EarlyView.
ABSTRACT Crop modelling is essential for agricultural water management but often relies on simplified water balance routines that limit representation of soil moisture dynamics. To address this limitation, we developed a coupled model that integrates the 1‐D Richards equation, solved using a finite difference method into the FAO AquaCrop.

Machine Learning vs. Physics-Based Modeling for Real-Time Irrigation Management [PDF]

, 2020
Real-time monitoring of soil matric potential has now become a common practice for precision irrigation management. Some crops, such as cranberries, are susceptible to both water and anoxic stresses.

An Alert Regarding a Common Misinterpretation of the Van Genuchten α Parameter

Revista Brasileira de Ciência do Solo, 2018
Among the equations available to describe the relation between matric potential and soil water content, the soil water retention function, the most commonly used is the equation proposed by Van Genuchten in his 1980 landmark paper.

Field Studies on the Influence of High‐Voltage Direct Transmission Underground Cables on Soils Along the SuedLink Route in Southwest Germany

Journal of Plant Nutrition and Soil Science, EarlyView.
During regular operation of the SuedLink at a load ≤75 %, the average increase in temperature in the plowing horizon is expected to be less than 1.6°C in the soils along the route in Southwest Germany. ABSTRACT Background The SuedLink was planned as a high‐voltage direct‐current underground cable route. The construction itself is a massive intervention

Sewage Sludge and Cashew Bagasse Biochars Promote Changes in Selected Physical Attributes Related to the Structure of Degraded Dryland Soil

Journal of Plant Nutrition and Soil Science, EarlyView.
This study evaluated biochars from co‐pyrolysis of sewage sludge and cashew residues on physical quality of a degraded loamy sand soil. SPB applied at 20 Mg ha−1 reduced bulk density by 7.74%, whereas most porosity attributes were driven by soil reconsolidation rather than biochar. Aggregate stability varied with biochar type, with SPB promoting larger
