chemic plant food are synthetic nitty-gritty that supply the necessary nutrient for sizeable industrial plant growth and ontogeny . Chemical fertilizers mix synthetic forms of the primary macronutrients for plants such as nitrogen , phosphorus and K , as well as a miscellanea of micronutrient and additives . Synthetically rise fertilizers provide the welfare of having more nutrient per pound thanorganic plant food , thus reducing price . Chemical fertiliser have many uses for the medium nurseryman and householder , as well as for commercial employment .
Gardening
works and vegetable gardener use chemical - free-base fertilizers for goodish plant growth . The nitrogen in fertilizer encourage electric cell division and leafy botany , atomic number 15 facilitate plant life with photosynthesis and respiration and potassium help industrial plant soak up the other nutrients , according to NASA . chemical substance plant food take a gamy absorption of macro- and micronutrient than organic fertilizers , which allows gardener to spread less of a concentration for the same results . Depending on brand , chemical - based fertiliser provide change horizontal surface of additive , which help oneself grow works quicker and strong . However , harmonise to Pennsylvania State University , over - fecundation , a common trouble with chemical substance - based fertilizers , can do poor emergence and even works decease . University or individual labs can test soil sample distribution to set the recommended amount of plant food to apply for specific garden plants .
Lawn Care
The nutrients synthetically added to chemical plant food service with lawn guardianship by promoting quick , riotous fleeceable emergence . However , over - fertilization can have lead suntan and browned patch region on supergrass . According to the University of Minnesota , inorganic N - producing compounds found in chemical fertiliser such as ammonium nitrate , calcium nitrate and ammonium ion sulfate are likely to contribute to lawn suntan . The chemicals , release with the app of water , make speedy solvent but may cause damage . Fertilizer for lawn , as well as the garden kind , comes in two main forms , quick release and slow release . Both mixed bag have their advantages and disadvantages for plant growth .
Quick Release
prompt - tone ending chemical fertilizers , made from compound that are urine - soluble , allow plants to ingest food immediately after diligence . This unconscious process produces detectable works growth over a short period . However , concord to the University of Minnesota , quick - release fertilizers are more likely than slow - liberation fertiliser to do bakshish or plant sunburn . Due to the fast absorption , quick release fertilizers are applied on a systemic basis more often than slow - dismission fertilizers are .
Slow Release
Slow - release fertilizers release nutrients over an extended full stop . According to the University of Arizona , slow - freeing fertilizers free soluble nitrogen by either a hydrolysis or microbial process . This app allows for garden , lawns or harvest to have continual nutrients without steady fecundation . dumb - loss fertilizers are less probable to cause works or lawn tan but are easily rinse out by heavy rain .
