“…Earlier researchers revealed that as soil temperature increased, weed germination was reduced significantly [32] [33]. An experiment conducted by [34] which testing 4 different mulches, i.e. EVA, LDPE, COEX, and BDP on lettuce confirmed that soil solarization was capable of suppressing the weed growth.…”

Weeds are the major problem in organic crop production. Soil solarization is a method using clear plastic films to increase soil temperature to control pest organisms such as fungi, bacteria, and weed seeds. The study aimed to evaluate the effect of different plastic mulch color on weed seed inhibition. The experiment was carried out in CAPS Research Station located in Air Duku Village, Bengkulu, Indonesia at 1054 m above sea level, arranged in Randomized Completely Block Design with 3 replications. Treatments comprised 4 different colors of plastic films, i.e silver-black, black, clear, and red as well as control (without mulch). Plastic mulch was laid on 1 m wide x 2 m long raised soil bed for four weeks from April 20-May 23, 2016. Soil temperature underneath plastic mulch at depth of 5, 10, 15, 20 cm from the surface were measured daily at noon. After incubation, soil sample was collected from 0-5; 5-10; 10-15; 15-20 cm depths. Weed seed germination of each soil sample was tested in the greenhouse. A number of weeds were observed after four weeks. The experiment indicated that a month of soil solarization using clear plastic mulch resulted in greatest soil temperature, increasing by 0.54-1.84% as compared to control. Treatment of plastic mulches was effective to suppress seed inhibition at the soil depth of 0-15 cm, as indicated by numbers of germinated weed and its dry matter. Longer soil solarization is necessary to obtain the highest reduction of weed growth in the tropical highland organic farming system.

“…It may also control S. halepense rhizomes through the solarization effect (Law et al 2008). Tarping can raise surface soil temperatures to over 60 C in the summer (Candido et al 2012) and 45 C in the fall (Horowitz et al 1983). Solarization has been used to control several weed species in vegetable production systems, including perennials such as nutsedges ( Cyperus spp.)…”

Johnsongrass [Sorghum halepense (L.) Pers.] is one of the most problematic perennial grass weed species in row-crop production across the southern United States. Control of this species is especially challenging in organic systems due to a lack of effective options. A field experiment was conducted at the Texas A&M research farm near College Station, TX, from fall 2019 to spring 2021 to evaluate various nonchemical options for managing S. halepense in the fallow season, implemented over 2 yr in the same locations. The treatments included disking once, disking twice, disking + immediate flooding, disking + flush irrigation + flooding, disking twice + flooding after the first frost, periodic mowing, acetic acid treatment, and disking + tarping. Disking + immediate flooding, disking + flush irrigation + flooding, and disking + tarping were the most effective treatments. Compared with the nontreated control plots, these treatments reduced S. halepense aboveground density (<9 plants m−2 vs. 64 plants m−2), aboveground biomass (<80 g m−2 vs. 935 g m−2), rhizome biomass (<4 g m−2 vs. 55 g m−2), rhizome node number (<25 nodes m−2 vs. 316 nodes m−2), and rhizome length (<42 cm m−2 vs. 660 cm m−2). Disking twice + flooding after the first frost did not show a consistent impact. Periodic mowing also reduced S. halepense density (12 plants m−2 vs. 64 plants m−2) and other variables compared with the control plots at the end of the study in spring 2021. Disking alone once or twice each growing season or repeated application of acetic acid failed to control S. halepense. These results indicate that well-timed nonchemical management practices such as tarping and flooding implemented during the winter fallow can be very effective in reducing S. halepense densities.

“…Soil solarization is a technique in which the soil, moistened and mulched with a transparent plastic film, is heated by solar radiation for several days up to thermal levels lethal or injurious for soilborne pests [3]. On the other hand, biofumigation consists of soil solarization in which some organic matrix is added to have both the release of biocidal gases, such as alcohols, aldehydes, sulfides and isothiocyanates, resulting from the degradation of soil organic amendments, and to have some biostimulant or biofertilizer effects [4][5][6].…”

Yield Response and Antioxidant Activity of Greenhouse Organic Pumpkin (Cucurbita moschata Duch.) as Affected by Soil Solarization and Biofumigation

In intensive cropping systems, soil fumigation, i.e., the use of gas chemical pesticides applied to the soil covered with impermeable plastic film, represents an effective method to control most of the soilborne pests. However, its general non-selectivity to the useful soil microflora and microfauna together with their significant environmental problems has limited their use. Numerous studies have concerned the application of less impactful but, at the same time, equally effective disinfection methods. These are techniques with a low environmental impact that are particularly suitable for horticultural systems. Among these, both soil solarization and biofumigation are popular techniques, even in organic vegetable cropping systems. This paper reports the results of a study to evaluate the effects of soil solarization on the yield response and the antioxidant levels of organic pumpkin (Cucurbita moscata Duch.). Solarization was carried out alone and with the addition of some organic matrices, such as compost, manure and green manure species. The evaluation of the antioxidant activity was carried out with DPPH (1,1-diphenyl-2-picrylhydrazyl radical) assay: DPPH has a specific absorption band, which disappears in presence of an antiradical compound, showing its antioxidant capacity. Our results revealed that the pumpkins grown in solarized soil had IC50, i.e., the concentration of sample which reduced the initial DPPH of 50%, values ranging between 0.6 to 18.0 mg mL−1, lower than the values of IC50 of pumpkins grown in non-solarized soil, which ranged from 36.0 to 43.6 mg mL−1. The obtained results highlighted the validity and utility of solarization for the organic vegetable crops. Furthermore, this technique has also shown its effectiveness in the long term since yield increases concerned several crops in succession. Finally, our results highlighted that heat treatment solarization can influence the level of several compounds in the pumpkin, and, therefore, also of the polysaccharides.
