This study was performed to evaluate the chemical properties and soil quality of strawberry, watermelon, and tomato-grown soils in the intensive plastic film houses. Soil testing data (43,288), uploaded on Korean soil information system (http://soil.rda.go.kr) from 2010 to 2019, were analyzed. The study showed that the average values of pH and organic matter (OM) have been maintained under the optimum ranges, whereas electrical conductivity (EC), available phosphate (Avail. P2O5) and exchangeable (Exch.) cations (K, Ca, and Mg) were increased by 1.2 times in strawberry, and 1.3 times in watermelon and tomato. In addition, the soil chemical quality was the lowest in tomato and followed by watermelon and strawberry. Especially, a chemical quality of tomato-grown soils revealed the most rapid decrease until 2019. In order to improve soil environment for strawberry, watermelon, and tomato cultivation under the plastic film houses, a comprehensive soil management technique such as application of rice straw, chelating agent and microbal material, deep tillage, cultivation of hyperaccumulator for salts should be used to reduce the accumulated nutrients, and considering the results of the soil testing, adequate amount of fertilizer, compost, and soil amendment should be supplied to ensure stable crop productivity.

“…In Korea, lily cultivation is carried out by protected cultivation [ 8 ], which is exposed to excessive input of fertilizer [ 15 ]. The contribution of a large amount of chemical fertilizer and compost increases salt accumulation in the rooting zone, and decreases the soil’s chemical and physical properties [ 16 , 17 ]. In addition, high salinity water frequently increases the accumulation of salts in soil [ 18 ].…”

Salt stress is a major constraint of crop productivity because it reduces yield and limits the expansion of agriculture. This study investigated salt tolerance in 26 cultivars of cut lilies (Lilium hybrids) by examining the effect of salt stress on the growth and morphological characteristics of flowers and leaves and their physiological properties (chlorophyll a fluorescence). Salt stress significantly affected the growth and development of cut lilies. Canonical discriminant analysis indicates that the middle leaf width, number of flowers, first flower diameter, petal width, and chlorophyll a fluorescence were correlated with salt stress, whereas plant height, the middle leaf length, days to flowering, and sepal width were less affected by the stress. The cultivars examined were divided into three groups: Group 1 included the salt-sensitive cultivars, which failed to develop normal flowers; Group 2 included cultivars sensitive to salt stress but tolerant to osmotic stress; and Group 3 was the salt-tolerant group, which developed commercially valuable flowers. In conclusion, the cultivars contained a variable range of cut flower characteristics and growth traits that can be employed for lily breeding programs and as material for molecular mechanisms and signaling networks under salt stress.
