Nope, skip using coffee grounds on your houseplants. “You can cause a lot of damage with the active ingredients still in the grounds that will leach into the soil and potentially injure roots ...
The dry coffee grounds contain significant amounts of potassium (11.7 g/kg), nitrogen (27.9 g/kg), magnesium (1.9 g/kg), and phosphorus (1.8 g/kg). [5] The quantity of caffeine remaining in used coffee grounds is around 48% of that in fresh coffee grounds. [6] There are significantly less tannins in used coffee grounds than fresh coffee grounds ...
Salts dissolved from the soil accumulate at the soil surface and are deposited on the ground and at the base of the fence post. Saline incrustation in a PVC irrigation pipe from Brazil. Soil salinity is the salt content in the soil; the process of increasing the salt content is known as salinization. [1] Salts occur naturally within soils and ...
A wide variety of materials have been described as soil conditioners due to their ability to improve soil quality. Some examples include biochar, [3] bone meal, blood meal, coffee grounds, compost, compost tea, coir, manure, [4] straw, peat, sphagnum moss, vermiculite, sulfur, lime, hydroabsorbant polymers, [5] biosolids, [6] and rock flour.

Salinity in soil is caused by irrigating with salty water. Water then evaporates from the soil leaving the salt behind. Salt breaks down the soil structure, causing infertility and reduced growth. [citation needed] [14] The ions responsible for salination are: sodium (Na +), potassium (K +), calcium (Ca 2+), magnesium (Mg 2+) and chlorine (Cl −).
The salt concentration Cp can be taken as a part of the salt concentration of the soil in the unsaturated zone (Cu) giving: Cp = Le.Cu, where Le is the leaching efficiency. The leaching efficiency is often in the order of 0.7 to 0.8, [14] but in poorly structured, heavy clay soils it may be less.
Nutrients in the soil are taken up by the plant through its roots, and in particular its root hairs.To be taken up by a plant, a nutrient element must be located near the root surface; however, the supply of nutrients in contact with the root is rapidly depleted within a distance of ca. 2 mm. [14] There are three basic mechanisms whereby nutrient ions dissolved in the soil solution are brought ...
