| Draggable item | arrow_right_alt | Corresponding Item |
|---|---|---|
Peaty | arrow_right_alt | Largest particles among the different soil types. It’s dry and gritty to the touch, and because the particles have huge spaces between them, it can’t hold on to water. |
Sandy | arrow_right_alt | When moistened, it’s soapy slick. When you roll it between your fingers, dirt is left on your skin. It retains water longer, but it can’t hold on to as much nutrients as you’d want it to though it’s fairly fertile. Due to its moisture-retentive quality, its cold and drains poorly. |
Clay | arrow_right_alt | Smallest particles among the three so it has good water storage qualities. It’s sticky to the touch when wet, but smooth when dry. Due to the tiny size of its particles and its tendency to settle together, little air passes through its spaces. Because it’s also slower to drain, it has a tighter hold on plant nutrients |
Silty | arrow_right_alt | Becomes heavily saturated with water, once drained, it turns into a good growing medium. In the summer though, it could be very dry and become a fire hazard. (I kid you not—it is the precursor of coal.) The most desirable quality of it, however, is in its ability to hold water in during the dry months and its capacity to protect the roots from damage during very wet month |
Saline Soil | arrow_right_alt | High salt content, it can cause damage to and stall plant growth, impede germination, and cause difficulties in irrigation. The salinity is due to the buildup of soluble salts—high salt contents prevent water uptake by plants, leading to drought stress. |
