TO FIND OUT THE EFFECTS OF FERTILISERS ON THE GROWTH OF A CROP

Introduction:

A fertiliser is a mineral, which we put in plants to make a plant grow properly. There are three main minerals in a fertiliser, which is very important these are:

Nitrates, phosphates, potassium.

Nitrates - provide nitrogen, which is needed, for making protein.

Lack of nitrate stunt growth and yellow older leaves.

Phosphates - provide phosphorous needed for photosynthesis a respiration.

Lack of phosphates make poor root growth and purple younger leaves

Potassium - helps biological agents called enzymes to work properly. These enzymes are needed for photosynthesis and respiration.

Lack of potassium makes yellow leaves and dead spots

Farmers and gardeners use this kind of fertiliser because is make them grow bigger and good looking plants. Bigger and better means more money for them because the heavy the plant is the more money the farmers make.

Prediction:

I wish to find out which dose of fertiliser makes the best crops.

The general effect on the growth of plants used by fertiliser is that is that is give the plant good mineral for it to grew properly without any bad things happening e.g. yellow leafs

 

My prediction is that the cup with the 2* dosage makes the best crops.

I think this may happen because the 2* dosage have more advantage then the rest because it have a high amount of dosage which might makes the crops grow faster quicker.

The normal amount of dosage will come next because it has a normal of dosage a typical plant need.

The half amount of dosage will come next because it have the amount of dosage mixture of fertiliser with water, which have the minerals and water a plants need.

Join now!

The pot with the water will come last because it has no fertiliser to help it grow which mean there are minerals, which helps it grow.

What might happen if I use?

Twice the amount of dosage - I think it will grow the best crops out of them all because of the high amount of dosage.

Half the amount of dosage- I think it will grow but now as well as the 2* the amount of dosage because it only has half the amount.
