“…Soil temperatures did rise above the 27.5°C threshold again in July 2017, but it was after plants were well established. Similarly, Kader et al (2017) found that soybean yield in a region experiencing very hot summer weather was greatest with a paper mulch compared with black PE mulch because of the root zone cooling effects. During the critical time when the pepper transplants were becoming established in June, average, minimum, and maximum air temperatures were greater in 2018 (24.0, 19.3, and 30.4°C, respectively) than in 2017 (22.8, 17.7, and 28.9°C, respectively).…”

Plasticulture systems with polyethylene (PE) mulch and drip tape are common for production of peppers (Capsicum annuum L.) in the United States because of their soil warming, moisture conservation, and other advantageous effects. However, disadvantages include disposal costs and plastic pollution of the environment and temperature stress in warm climates with black mulch. Use of biodegradable plastic mulches (BDMs) is becoming more common, as they provide the same benefits of PE mulch without the disposal problems. In 2017 and 2018, we conducted experiments in Knoxville, TN, comparing production of pepper fruit with five different BDM [one white-on-black (WOB) and four black], one black PE mulch, one brown creped, paper mulch, and bare ground control treatments. We also measured the durability and effectiveness of weed suppression of the different mulches over the growing season compared with a hand-weeded bare ground control. Most mulches were degraded, with 40% to 60% of the soil exposed by the end of the season, with the exception of the paper mulch, which was completely degraded at the end of both seasons. Yields were similar among treatments in 2017, with the exception of Naturecycle, which had the lowest yield. Weed pressure was severe, especially in 2018, largely due to early penetration of all mulches except paper by nutsedge. Due to the early and season-long weed pressure and heat stress in black mulches, there were fewer healthy plants in all black-colored mulch treatments in 2018, leading to reduced yields in these treatments. Paper mulch was the only treatment that prevented nutsedge growth; therefore, this treatment and the hand-weeded bare ground treatment had the greatest yields in 2018. WOB also had yields comparable with paper and bare ground plots in 2018, likely due to the cooling effect of the white mulch. The results suggest that in hot climates and in fields infested with nutsedge, paper mulches perform best for midseason pepper cultivation due to the cooling effects and superior weed control.

“…Moreover, the suitability of soil moisture and temperature for crops is changing in different growing stages. Organic mulching degrades to the soil that enhances organic matter consequently increases the water holding capacity of the soil (Kader et al 2017c).…”

Agricultural water resources have been limited over the years due to global warming and irregular rainfall in the arid and semi-arid regions. To mitigate the water stress in agriculture, mulching has a crucial impact as a water-saving technique in rain-fed crop cultivation. It is important mainly for preserving soil moisture, relegating soil temperature, and limiting soil evaporation, which affects the crop yield. Mulching has many strategic effects on soil ecosystem, crop growth, and climate. Mulch insulates the soil, helping to provide a buffer from cold and hot temperatures that have a crucial activity in creating beautiful and protected landscapes. This study has accumulated a series of information about both organic and plastic mulch materials and its applicability on crop cultivation. Moreover, future research potentials of mulching with modeling were discussed to quantify water loss in agriculture.

“…The increase in volumetric moisture content may be as a result of greater capillary forces under the nylon and plastic cover accumulated water from lateral flow through the buffer zone (Kader et al, 2017). These plastic and nylon cover also prevented soil surface evaporation (Doring et al, 2005), thereby conserving moisture in the soil (Shah et al, 2013).…”

An in-depth knowledge on the soil thermal properties under different soil solarization techniques is essential for soil treatment against soil-borne pathogens. This paper presents an investigation on effects of different soil solarization materials on soil thermal properties, organic matter and aggregate stability under field conditions. This study evaluates three materials: translucent whitish plastic (TWP), transparent nylon (TN) and black nylon (BN) each at three thickness levels (0.05, 0.10 and 0.15 mm) and control (bare soil). The parameters investigated in this study included soil temperature, organic matter, bulk density, volumetric moisture content, thermal conductivity, volumetric heat capacity, heat flux, thermal diffusivity and thermal effusivity. The results showed that the soil solarization materials varying in thickness influenced the soil heat energy transfer and had a significant effect on soil bulk density and volumetric moisture content. The results revealed that transparent nylon at a thickness of 0.05 mm recorded the highest soil temperature (62 o C) and was significantly higher than black nylon at a thickness of 0.15 mm (44 o C) and the bare soil (41 o C). Transparent nylon at a thickness of 0.05 mm also recorded the highest organic matter content (19.60 g kg -1 ). The bulk density of the bare soil (1.57 Mg m -3 ) was significantly higher than the bulk densities of soils covered with solarization materials. Transparent nylon at thickness of 0.05 mm had the highest volumetric moisture content (0.116 m 3 m -3 ) while translucent whitish plastic at a thickness of 0.15 mm recorded the lowest (0.401 m 3 m -3 ). Transparent nylon at a thickness of 0.05 mm transmitted the highest quantity of heat through a unit length of soil per unit cross-sectional area (2.50 W mk -1 ). The variation in volumetric heat capacity between the solarization materials was highly noted in transparent nylon (TN) at a thickness of 0.05 mm (2.65 J (m 3 K) -1 ) and less in bare soil (control) with a value of (1.65 J (m 3 K) -1 ). Transparent nylon with thickness of 0.05 mm transferred the highest heat per unit area of soil (42338.25 W.m -2 ), while bare soil transferred the lowest. The highest thermal diffusivity (1.35 m 2 s -1 ) was recorded in the soil with no solarization material. The soil under transparent nylon with thickness of 0.05 mm recorded the highest exchange of thermal energy (2.57 Jm -2 K -1 S -1/2 ) with the environment and was significantly higher than other solarization materials. The transparent nylon had the highest soil macro aggregate stability. This study will help farmers in terms of choice and adoption of affordable conservation methods in treating the soil against soil-borne pathogens.
