Special Issue Information

Dear Colleagues,

We would like to invite you to contribute to a Special Issue in the MDPI journal AgriEngineering.

The title of the Special Issue will be “Remote Sensing of Soil Moisture and Properties for Agricultural Applications”.

The constant search for higher yields and lower production costs is an objective present in 21st century agriculture. Water is a key input to ensure agricultural production and increase productivity. Compared to other inputs, water is less expensive and more important for agriculture.

The water content in the soil must be known so that the farmer can make the best decisions. Soil properties such as texture, soil density, porosity, and infiltration capacity, among others, are also used for this purpose. However, these factors present spatial and temporal variability. Therefore, a more detailed monitoring of these factors is needed, where agricultural producers are resorting to technology.

In this context, one of the advances in this area has occurred with the increasing use of aerial and orbital images in agriculture. The images provide information that can be used to determine moisture and other soil characteristics. For this, the use of data science and machine learning techniques plays a prominent role in the process of transforming data into soil information.

The following are some of the topics proposed for this Special Issue (not an exhaustive list):

-  Detection of physical-hydric characteristics of soil using remote sensing;

-  Determination of soil moisture via crop evapotranspiration obtained by remote sensing;

-  Remote sensing for soil mapping;

-  Development of soil-related indices based on remote sensing data;

-  Use of remote sensing to identify spatial and temporal variability of soil physical-hydric characteristics;

-  Integration of remote sensing data and sensors installed on the ground;

-  Monitoring of soil factors related to agricultural production.

We hope you will contribute your high-quality research, and we look forward to reading your valuable results.

This work aimed to evaluate the effect of calcium on the development of corn plants grown with the omission and excess of calcium in a nutrient solution. The experiment was conducted in a greenhouse from March to May 2012. Three concentrations of calcium (0, 200, and 600 mg Ca L−1) were added to the nutrient solution, which was renewed weekly, for a total of 40 days. The following variables were measured weekly: the number of leaves, average stem diameter, dry weight of the plant shoots and roots, and visual leaf diagnosis. The results showed that when the plants were deprived of calcium, their root systems were significantly reduced, as determined by the Tukey test (p ≤ 0.05). The plants with calcium deprivation had shorter roots and a dark brown color and displayed initial symptoms of chlorosis in their young leaves, which eventually led to necrosis and tipping. Hydroponics is promising and has shown satisfactory production results, contributing to the improvement of the environment, job creation, and increased profit for rural producers. Full article

The different conditions of soil vegetation cover combined with irrigation management and/or agricultural production systems can influence soil moisture content and crop yields. This study investigated the impact of agricultural production systems and center pivot irrigation management on soil moisture content during the cultivation of soybean and off-season corn crops. Two field experiments were conducted during the 2018–2019 growing season in tropical Cerrado soil conditions; one experiment consisted of the application of three irrigation water depths (0%, 50%, and 100% of the crop evapotranspiration) during soybean cultivation in a no-tillage system under ruzigrass (Urochloa ruziziensis) straw, and the second experiment consisted of the intercropped or nonintercropped cultivation of corn hybrids with ruzigrass in an agricultural area with and without the influence of eucalyptus reforestation. The volumetric soil moisture was measured using an electronic soil moisture meter (Hidrofarm), and the 1000-grain mass and yield of the soybean and corn were measured in the two trials. Irrigation and the no-till system did not influence soybean yields. The soybean cultivars NA 5909 RG and TMG 7067 IPRO presented TGM above 180 g, and this represented on average a 22% higher TGM than the BMX DESAFIO RR and CD 2737 RR. The presence of eucalyptus forest promoted a 1.5% increase in soil moisture in the corn crop. Soil management systems, such as irrigation, use cover crops, which may not increase the productivity of soybean and corn crops as expected. Full article
