Air temperature in the greenhouse ranged from 15 to 28 °C, water supply was adapted to maintain soil moisture content around 15%% (w/w).
Plants grown under drained soil were watered daily to maintain soil humidity at field capacity.
This will help, in part, to maintain soil fertility.
Agricultural mulch films made have greatly contributed to the increase in the production of high-quality vegetables as they have been used to cover cultivated fields to maintain stable soil temperature and humidity, as well as to prevent weed growth.
Vermicompost stimulates to influence the microbial activity of soil, increases the availability of oxygen, maintains normal soil temperature, increases soil porosity and infiltration of water, improves nutrient content and increases growth, yield and quality of the plant (Arora et al. 2011).
Agricultural mulch films, which are used for covering cultivated fields to maintain a stable soil temperature and to prevent weeds from growing, are the most common and highly consumed plastic products on agricultural farm lands.
The experimental results show that BSCs increased infiltration during wet periods by increasing significantly greater hydraulic conductivity and macroporosity (p < 0.01), and reduced soil evaporation by maintaining a lower soil temperature than PSCs and IPZs during dry periods.
Contrastingly, a thicker and permanent snowpack maintained circum-zero soil temperatures during winter which limited the microbial community's turnover and release of organic and inorganic N.
Plants of 'Penncross' were exposed to 35 °C soil temperature (heat stress) or 20 °C (control) in water baths while air temperature was maintained at 20 °C in growth chambers.
