“…This method is found to be misleading. Often, after a dry period, rainfall dampens only the top section of the arable-humus horizon, so an assessment of the moisture content of the soil surface may suggest an abundance of water, while a few cm below the dampened layer the soil profile is not saturated (Wang et al 2018) [24] (Fig 3). On the other hand, watering the crop until the soil is saturated is both uneconomical and detrimental to the environment.…”

Current climate changes, including drought, represent one of the most severe and extreme natural phenomena, directly affecting the environment, economy and society, and increasingly leading to soil degradation. In drought-stricken areas, losses in agricultural production are driving up food prices. The world's demand for water will continue to grow further in the coming decades. In view of the presented facts, there is a tremendous need for a systemic approach to saving water in the process of soil reclamation and conducting multidisciplinary research in this field. The problem of fertilization is linked to reasonable irrigation. These processes ought to be synchronized and run simultaneously, under the control by the system. This paper presents a prototype measurement probe as an element of a measurement network and the results of tests of its application in under use. The purpose of this research was testing a cheap DIY to solution identify the availability of water resources in the soil layer where the major plant root mass is found, i.e., to a depth of up to 110 cm, and to rationalize the management and improve the efficiency of water use during irrigation, as well as to monitor the migration of water in the soil in the era of climate change. The conducted tests have yielded concrete conclusions - current climate change is already resulting in unusual situations, including the different behaviour of water migrating through the soil. Considering that a wide variety of soils and geological systems are present, it is extremely important to understand these mechanisms in great detail, which makes the created solution feasible. Such a detailed analysis of water migration in soil under use can very successfully support, for example, a low-cost precision irrigation (preventing drought), or fertilization, indicating periods when and where to introduce nutrients after rainfall so that they naturally reach the depth of the largest root mass as quickly as possible. The DIY solution can be crucial in Third World countries by conducting at least single, cheap soil moisture measurements, and in many other places affected by the problem of water deficit, it can be an alternative to extend existing monitoring systems.

“…Many scholars have investigated soil porosity to good effect but most of the existing research focuses on the influence of rainfall (Armenise et al., 2018; Lin et al., 2012; Wang et al., 2018), soil improvement measures (Ahmad et al., 2009; Josef et al., 2017), cultivation methods (Celik et al., 2012; Xue et al., 2018) and planting patterns (Iqbal et al., 2014; Park et al., 2011; Xia et al., 2019) on soil pores, and little attention has been paid to the influence of coal mining on soil structure. However, coal mining has led to the degradation of vegetation cover and soil quality and to the dumping of overburden materials in mining areas in north-west China (Bi et al., 2018; Li et al., 2015).…”

To study the influence of coal mining on the porosity of shallow sandy loam under conditions of shallow seam mining in thick, loose layers in north-west China, a typical surface sandy loam stratum in Shaanxi Province was taken as the study area, and experiments were performed to test the variation of soil porosity at different depths of 0–10 m in strata before, during and after mining therein. The experimental results demonstrate that the overall average porosities in the disc-shaped edge area, the disc-shaped edge area to the disc-shaped basin bottom area and the disc-shaped subsidence centre area of shallow sandy loam in mining increased by (23.51, 18.07 and 22.61%) respectively compared with that before mining. Mining meant that the soil porosity in the period of stable subsidence after mining changed significantly in the disc-shaped edge area and the disc-shaped edge to the disc-shaped basin bottom area. The disc-shaped edge area shows a trend of slowly rising porosity with the increase of depth, and the disc-shaped edge area to the disc-shaped basin bottom area shows a trend of gradually increasing first and then gradually becoming stable. Although the porosity in the central area of disc-shaped subsidence increased before mining, its trend was similar to that before mining. Although the change in soil porosity in the period of post-mining settlement stability is greater than that before mining, it is best fitted by a quintic polynomial. In general, the rate of change of soil porosity in the study area shows similar trends with depth. It showed a U-shaped variation that first decreased, stabilised for a distance and then gradually increased. This study provides theoretical support for surface soil remediation and ecological environment restoration in coal mining areas.
