The effect of winter flood irrigation with saline water on groundwater in a typical irrigation area
Flood irrigation in the winter has been widely applied in northwest China for several years, but little attention has been paid to the flood irrigation program to date. In order to seek a reasonable irrigation quota, a flood irrigation experiment using two common quotas (1,800 and 1,200 m3 ha−1) was conducted in an area irrigated by saline water in the Nanjiang basin with shallow ...

Effects of magnetized water application on soil and maize growth indices under different amounts of salt in the water
Application of low quality water for irrigation is compulsive in facing water scarcity. Use of a magnetic field is an approach to overcome this challenge. This study examined the impact of magnetic field technology on improving germination under water of different salinity levels. An experiment was conducted to determine the effects of saline water levels, i.e. (S1):0.5, (S2):2, (S3):4 and ...

What is Soil EC Sensor?
Soil EC (Electrical Conductivity) sensor is an essential tool for modern agriculture, enabling farmers to optimize crop yields by measuring the nutrient levels in the soil. EC sensors measure the soil's ability to conduct electricity, which is a proxy for soil salinity and nutrient content. This article will explore the basics of soil EC sensors, their applications in agriculture, and the factors ...

Characterizing and classifying variability in corn yield response to nitrogen fertilization on subfield and field scales
Marked spatial and temporal variability in yield response to N fertilizer observed in individual yield response trials creates a high degree of uncertainty when estimating economic optimum rates (EORs) of N for a group of trials and when extrapolating these rates from one location to another. A survey was conducted to characterize and classify variability in yield response to N on subfield and ...

Measurement of Steady-State Soil Water Flux across a Soil Horizon Interface
Soil horizon interfaces have been shown to be focal points for localized, three-dimensional redistribution of water and solutes in field soils. Therefore, understanding of the physics of water flow and transport in layered soils requires experimental observations of the magnitude and variability of local soil water flux under a variety of well-defined boundary conditions. We developed a time ...

The Accurate Way to Soil Moisture Sensing
Why Acclima soil moisture sensor technology is superior in terms of accuracy and cost Permittivity is a property of matter and is well characterized especially for materials that are electrically non-conductive. Water in its pure form is non-conductive. Permittivity quantifies the charge holding capacity for insulating materials. It is the ratio of stored electric charge to an applied electric ...

Multiscale control of vegetation patterns: the case of Doñana (SW Spain)
The early studies about the plant ecology of Doñana carried out at a small scale showed that the main process controlling vegetation composition of the stabilized dunes was soil water availability. However, the extrapolation of this model to larger spatial scales failed to explain observed vegetation patterns. In this work, the vegetation patterns and the processes causing them are studied at a ...

Evaluation of zone soil sampling approaches for phosphorus and potassium based on corn and soybean response to fertilization
Soil sampling approaches have been compared based on soil-test variation. This study evaluated sampling approaches for P and K based on yield response to fertilization. Strip trials were established on four fields for P and three fields for K managed with corn (Zea mays L.) and soybean (Glycine max L. Merr.) rotations and evaluated 3 or 4 yr (27 site-years). Treatments replicated three to four ...

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 ...

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 ...

Effect of biochar on maize yield and yield components in rainfed conditions
Int. J. Agron. Agri. Res. 12(3), 46-51, March 2018. To investigate the maize yield and nutrient concentration in its leaves as affected by biochar from different organic materials (wheat straw and sugarcane bagasse), a field experiment was conducted on maize crop during 2013 at koont research farm chakwal. The treatments were control, wheat straw biochar at 5t ha-1, and 10t ha-1, sugarcane ...

Variable Rate Seeding with Drone Imagery
Getting a good crop canopy across the entire field is important for better crop quality and higher yield. One way of achieving this is by varying the amount of seeds. In recent years more and more farmers have started using variable-rate technology. By coupling the tractor’s GPS equipment with the seed drill, the seed amount can be varied across the field based on a predetermined plan. The ...
