Cacti and succulents may do not do well, in a terrarium, as it gets too humid. For such plants, a dish garden is better. [5] A terrarium may in a closed container. The following plants are recommended [6] African violets, Aleo, Begonia, Bromeliad; Bonsai trees has been grown in dish gardens, for thousands of years, Peace lily, Philodendron ...
[10] [2] The drainage layer may be constructed via coarse gravel, stones, expanded clay aggregate, or may be wholly synthetic; the drainage layer is typically separated from the overlying substrate with a fine plastic mesh. [3] [10] Additionally, some bioactive terraria include leaf-litter, which can serve as food and microhabitat for the ...
Roughly speaking for agriculture (top layer soil), soil is 25% water, 25% air, 45% mineral, 5% other; water varies widely from about 1% to 90% due to several retention and drainage properties of a given soil. The role of soil water retention is profound; its effects are far reaching and relationships are invariably complex.
In some instances, subsurface drainage can be achieved simply by breaking up slowly permeable soil layers by deep plowing (sub-soiling), provided that the underground has sufficient natural drainage. In other instances, a combination of sub-soiling and subsurface drains may solve the problem.
The site will have been levelled for even drainage. Breaking up the soil. Compacted soil will be broken up by digging. This allows air and water to enter, and helps the seedling penetrate the soil. Smaller seeds require a finer soil structure. The surface the soil can be broken down into a fine granular structure using a tool such as a rake.
These plants tend to propagate in this manner anyway, and potting a new limb will give extra plants without having to sow new seed. Simple layering can also help when a plant has overgrown its pot and is drooping over the side. The long stem is layered into another pot until it roots, thus bringing it back to soil level. [6]
Purdue Improved Crop Storage (PICS) bags (formerly known as Purdue Improved Cow-pea Storage bags) [1] are bags developed by scientists at Purdue University [2] to store grain and seeds. They use hermetic storage technology to reduce loss of post-harvest cowpea ( Vigna unguiculata ) due to bruchid infestations in West and Central Africa .
Surplus water percolating through the soil profile transports soluble and suspended materials from the upper layers to the lower layers (illuviation), including clay particles [47] and dissolved organic matter. [48] It may also carry away soluble materials in the surface drainage waters. Thus, percolating water stimulates weathering reactions ...
