on plants at their peak growing cycle
. This is when the plant is leafing out for deciduous species, flowering, or putting on new growth after leaving the dormant winter stage. The time of year for fertilizing most plants would then be spring.
Can you farm without fertilizer?
Plants need nitrogen, and many plants depend on fertilizers to get enough. But scientists
have been growing plants without fertilizers
. … However, to make their food, and to grow properly, plants need nutrients (chemicals) such as nitrogen, phosphorus, potassium, and calcium from the soil.
Are fertilizers necessary?
Plants need to be fertilized
because most soil does not provide the essential nutrients required for optimum growth. … It took nutrients from the soil to build those plant tissues. By fertilizing your garden, you replenish lost nutrients and ensure that this year’s plants have the food they need to flourish.
How safe are fertilizers?
When used according to label directions, fertilizers
should cause little concern for human or animal safety
, but that can change quickly when important instructions go unread or ignored.
How do fertilizers cause water pollution?
Fertilization of surface waters (eutrophication)
results in, for example, explosive growth of algae which causes disruptive changes to the biological equilibrium [including fish kills]. This is true both for inland waters (ditches, river, lakes) and coastal waters. Groundwater is being polluted mainly by nitrates.
Why are fertilizers harmful to the environment?
When the excess nutrients from all the fertilizer we use runs off into our waterways, they
cause algae blooms sometimes big
enough to make waterways impassable. When the algae die, they sink to the bottom and decompose in a process that removes oxygen from the water.

- Use nitrification inhibitors.
How we can reduce the nitrogen?
We already know how to reduce our nitrogen footprint: use less nitrogen fertilizer,
eat fewer energy-intensive foods
, and try to minimize fuel-heavy forms of transportation, like airplane travel.
What steps can be taken to prevent the usage of pesticides in growing crops?
- Choose plants resistant to insects and diseases.
- Eliminate lost plants, which can be shelter to insects and diseases.
- Make weed control before blossom.
- Use physical controls such as traps, barriers, and mechanical removal.
What can be done to prevent eutrophication?
planting vegetation along streambeds to slow erosion and absorb nutrients. controlling application amount and timing of fertilizer. controlling runoff from feedlots. The best, easiest, and most efficient way to prevent eutrophication is by
preventing excess nutrients from reaching water bodies
.

How do you Fertilise plants?
The simplest and safest method of fertilising is to use
a slow release fertiliser
. Several of these will only become active when the soil is above a particular temperature or moisture level, so plants will absorb and utilize them only when they are actively growing and require nutrients the most.
