Plant growth, root development, and seed and fruit development are usually reduced in potassium-deficient plants. Often, potassium deficiency symptoms first appear on older (lower) leaves because potassium is a mobile nutrient, meaning that a plant can allocate potassium to younger leaves when it is K deficient.

John Innes compost is a set of four soil-based formulae for growing media, developed at the former John Innes Horticultural Institution (JIHI), now the John Innes Centre, in the 1930s and released into the public domain. The formulae contain loam, peat, sand, and fertiliser in varying ratios for specific purposes. These composts are used to ...
A soil test may be done to analyze the chemistry of a potting mix, despite the mix not necessarily being made of soil.

The main method is a saturated media extract (SME), which tests the chemical contents of a water extract of the mix.

Soil acidification refers to the process by which the pH level of soil becomes more acidic over time. Soil pH is a measure of the soil's acidity or alkalinity and is determined on a scale from 0 to 14, with 7 being neutral. A pH value below 7 indicates acidic soil, while a pH value above 7 indicates alkaline or basic soil.
