Fertilizers
Fertilizers are chemical compounds given to plants to promote growth; they are usually applied either through the soil, for uptake by plant roots, or by foliar feeding,
for uptake through leaves. Fertilizers can be organic (composed of organic matter), or inorganic (made of simple, inorganic chemicals or minerals).
They can be naturally occurring compounds such as peat or mineral deposits, or manufactured through natural processes (such as composting) or chemical processes.
These chemical compounds leave lawns, gardens, and soils looking beautiful as they are given different essential nutrients that encourage
plant growth.
They typically provide, in varying proportions, the three major plant nutrients (nitrogen, phosphorus, potassium: N-P-K), the secondary plant nutrients
(calcium, sulfur, magnesium) and sometimes trace elements (or micronutrients) with a role in plant or animal nutrition: boron, chlorine, manganese, iron,
zinc, copper, molybdenum and (in some countries) selenium.
Weed Control - Herbicides
A herbicide is used to kill unwanted plants. Selective herbicides kill specific targets while leaving the desired crop relatively unharmed.
Some of these act by interfering with the growth of the weed and are often synthetic "imitations" of plant hormones.
Herbicides used to clear waste ground, industrial sites, railways and railway embankments are non-selective and kill all plant material with which they come into contact.
Smaller quantities are used in forestry, pasture systems, and management of areas set aside as wildlife habitat.
