Benefits of minimum tillage case study
In Hungary, the MARGINS project is being conducted near Lake Balaton - the largest lake in Central Europe. The lake is renowned for its beauty and wildlife. Its surrounding hilly landscape is covered with rich brown forest soil. This landscape is, however, prone to soil erosion -in particular, rills develop when soil is weakened by excessive tillage and exposed to intense rainstorms. If not ...

Application and principle of soil moisture sensor
Soil moisture sensor is a device for measuring soil moisture content. It plays a vital role in agricultural and environmental monitoring, allowing accurate assessment of soil conditions and timely intervention. In this article, we will explore the application and principle of soil moisture sensors. Soil moisture sensors work by measuring the electrical conductivity of soil. When soil contains ...

Evaluation of a Direct-Coupled TDR for Determination of Soil Water Content and Bulk Electrical Conductivity
Introduction Signal degradation in coaxial cables and interconnects is a long-standing problem in the practical deployment and calibration of time domain reflectometry (TDR) for soil water content monitoring. Acclima, Inc.1 has recently commercialized a TDR sensor (TDR-315) with all electronics required for waveform acquisition embedded in the probe head thereby avoiding signal degradation. Our ...

Genotypic variation in peanut for transpiration response to vapor pressure deficit
Conservation of soil water resulting from decreases in stomata conductance under atmospheric high vapor pressure deficit (VPD) conditions is a possible approach for enhanced tolerance of water deficit by crops. Water deficit is usually a concern in peanut (Arachis hypogea L.) since it is frequently grown on sandy soils with low water-holding capacity. Seventeen peanut genotypes were studied to ...

Evaluation of a Direct-Coupled TDR for Determination of 1 Soil Water Content and Bulk Electrical Conductivity
Signal degradation in coaxial cables and interconnects is a long-standing problem in the practical deployment of time domain reflectometry (TDR) for soil water monitoring. Acclima, Inc. has recently commercialized a TDR sensor (TDR-315) with all electronics required for waveform acquisition embedded in the probe head. We calibrated ten TDR-315 sensors and conventional TDR for apparent ...

Surfactant-Enhanced Desorption of Atrazine and Linuron Residues as Affected by Aging of Herbicides in Soil
Abstract In the present work, we studied the efficiency of two surfactants, one anionic (SDS) and other non-ionic (Triton X-100), in the desorption of atrazine and linuron after 0, 3, and 9 months of soil-herbicide aging time. Batch desorption studies were conducted in soil-water and in soil-water-surfactant systems. The kinetic pattern of desorption was biphasic, a slow desorption following an ...

Tillage requirements for integrating winter-annual grazing in peanut production: plant water status and productivity
The use of crop rotation systems involving winter-annual grazing can help peanut (Arachis hypogaea L.) producers increase profitability, although winter-annual grazing could result in excessive soil compaction, which can severely limit yields. We conducted a 3-yr field study on a Dothan loamy sand in southeastern Alabama to develop a conservation tillage system for integrating peanut with ...

Axle-load impacts on hydraulic properties and corn yield in no-till clay and silt loam
Wheel traffic-induced compaction in no-till (NT) farming can alter soil hydraulic properties and reduce crop yields, but specific information on the impacts of different levels of axle loads on the relationships between soil hydraulic properties and crop yields under long-term NT systems is limited. Thus, this study set out to measure the differences in soil hydraulic properties including ...

Types and maintenance of soil salinity sensors
Background: When people think of salt in relation to crops, the impression is that salt is bad for plant growth. However, it must be remembered that whenever we apply fertilizer, we are adding salt to the soil. So, when measuring soil salt, it can be a case of too much or too little. If the salinity is too high, the roots cannot absorb water. If the salinity is too low, the plants may lack ...
