“…Model watermark 200SS, Tension-based soil moisture sensors have been considered the best method to determine if a crop needs water since most vegetables experience reductions in yield and quality under prolonged periods of high soil water tensions. Tension thresholds that optimize production have been determined for many vegetable species [17,19], including broccoli [20], cabbage [21], cauliflower [22], lettuce [23,24], potato [25], and tomato [26]. An advantage of tension thresholds is that they are less influenced by soil texture than volumetric moisture thresholds.…”

Using evapotranspiration (ET) data for scheduling irrigations on vegetable farms is challenging due to imprecise crop coefficients, time consuming computations, and the need to simultaneously manage many fields. Meanwhile, the adoption of soil moisture monitoring in vegetables has historically been limited by sensor accuracy and cost, as well as labor required for installation, removal, and collection of readings. With recent improvements in sensor technology, public weather-station networks, satellite and aerial imaging, wireless communications, and cloud computing, many of the difficulties in using ET data and soil moisture sensors for irrigation scheduling of vegetables can now be addressed. Web and smartphone applications have been developed that automate many of the calculations involved in ET-based irrigation scheduling. Soil moisture sensor data can be collected through wireless networks and accessed using web browser or smartphone apps. Energy balance methods of crop ET estimation, such as eddy covariance and Bowen ratio, provide research options for further developing and evaluating crop coefficient guidelines of vegetables, while recent advancements in surface renewal instrumentation have led to a relatively low-cost tool for monitoring crop water requirement in commercial farms. Remote sensing of crops using satellite, manned aircraft, and UAV platforms may also provide useful tools for vegetable growers to evaluate crop development, plant stress, water consumption, and irrigation system performance.

“…Similar results were also found in other reports. Wang (2011a) found that the maximum soil temperatures in the soil surface layer were 4°C to 6°C lower in straw mulched plots than in non-mulched plots. Kar (2003) showed that the soil temperature was 3°C to 4°C less in rice straw-mulched plots than in nonmulched plots.…”

“…Mulching improves water conservation by reducing soil evaporation rates and increasing the water-use efficiency. Plastic mulch combined with drip irrigation has been used as an effective water-saving measure for the cultivation of potato in North China (Wang et al, 2011a;Liu et al, 2017;Zhang et al, 2017a).…”

Li et al. : The effect of mulching on soil temperature, winter potato (Solanum tuberosum L.) growth and yield in field experiment, South Abstract. The growth of winter potato, which is mainly planted in South China, is negatively affected by low temperatures. However, mulching is an effective method to increase soil temperatures. Here, the effects of black plastic, white plastic and rice straw mulch were assessed on soil temperatures, as well as on potato growth and yield through field experiment. The daily mean temperatures increased by up to 7.5°C and 6.5°C under black and white plastic mulch, respectively, compared with no mulch. Furthermore, the emergence rates and dates were accelerated by mulching, with the greatest tuber yields being observed under the black mulch treatment in two growing seasons. Additionally, mulching altered the soil's fertility properties and soil microorganism composition. Taken together, mulching with black plastic film is an effective method that benefits winter potato production in Typical Pearl River Delta Plain in south China.

“…Drip irrigation also provides application of soluble fertilizers and other chemicals along with irrigation water. Among modern irrigation techniques, drip irrigation has been shown to be a more water efficient alternative than furrow irrigation for potato (Wang et al, 2011). In fertigation Nutrient use efficiency could be as high as 90% compared to 40 -60% in conventional methods.…”
