Soil Water Content at Planting Affects Determining Agricultural Drought for Rainfed Spring Wheat

open access: yesAtmosphere, 2023
Agricultural drought often refers to water deficit in soil caused by a shortage of precipitation during a specific period in crop growing season, thus leading to final crop production failure. However, soil water content during planting may be related to

Experimental Study on Relationship between Free Load Swelling Rate and Water Content of Medium Expansive Soil

open access: yesAdvances in Civil Engineering, 2021
Expansive soil has the property of water swelling, which is related not only to the hydrophilic mineral composition of soil particles and the microstructure of soil, but also to the initial moisture content, dry density, and overburden condition of soil.
