Effectiveness of compost use in salt-affected soil in an automated greenhouse irrigation system

Abstract

Salinity problems reduce productivity on both irrigated and non-irrigated agricultural lands. Saline soils occur in arid and semi-arid regions where rainfall is insufficient to meet the crops’ water requirements and leach mineral salts out of the root-zone. Compost can play an important role in managing, mitigating, and improving the soil salinity negative effects. In this work, the compost effects on salt affected soil were studied. Therefore, physico-chemical parameters and morphological status of the plants divided into four plots in a greenhouse were studied. The first plot P0 is a control plot which was irrigated by fresh water, P1 was irrigated with fresh water mixed with compost, P2 and P3 were irrigated by saline water with an NaCl concentration of 5 g/L. An automated irrigation system was implemented to manage plots irrigation. The system was based on an electronic board and multiple sensors to track ambient temperature and humidity in the greenhouse, soil moisture and temperature of each plot, data was stored in a SD card. The results obtained showed that compost use increased stem growth by 23%, this percentage was improved by 10% for greenhouse tests.

A- Alleviating the harmful impact of salinity stress with different levels by using some organic techniques on vegetative growth characteristics of Wonderful cv. Pomegranate transplants

“…So, this will have a great impact on water and nutrient transportation as well as the production of gibberellin, cytokinin and auxin which strongly reflected on the quantity and quality of roots formed resulted in an increasing of lateral root length and intensity (Kheyrodin, 2022). Furthermore, the idea of using compost in mitigation the negative impact of the excessive using saline water is due to reducing the availability of interchangeable Na + around the root region by improving water infiltration and salt filtering which promote root production (Fouguira et al, 2023). Comparable results in improving root effectiveness in terms of establishment and elongation were strongly attributed to the safety application of Cyanobacteria "Spirulina platensis" which had valuable composition of macro and micronutrients in addition to polyamines which acquired by the decarboxylation of algal L-amino acids and acting as an active film surrounding the root zone against the biotic stress hence resulted in enhancing the overall plant growth (Mógor et al, 2018).…”

“…13 The plant grows under different pedoclimatic conditions. 14,15 In recent years, rosemary cultivation was successfully attributed in both arid and semi-arid regions with critical climate conditions. 16 This adaptable herb has several use in food, medication, spices, and cosmetics.…”
