Fertilizers to suit a variety of specified

are materials of natural or synthetic origin used to provide plant nutrients
which are deficient in soils which is essential to the growth of plants.  There are primarily two kinds of fertilizers
made up with different formulations to suit a variety of specified uses:
Organic fertilizers and Inorganic fertilizers. Organic fertilizers are
fertilizers derived from animal matter, animal excreta (manure), human excreta
and vegetable manure. Compost and crop residues are good examples. In contrast,
the majority of fertilizers used in commercial farming are extracted from
minerals or produced industrially. An inorganic fertilizer, commonly known as
Chemical fertilizer is a material of wholly or partially synthetic origin that
is added to the soil to sustain plant growth. Many such fertilizers contain acids, such
as sulfuric acid and hydrochloric acid, D1 which tend to increase the acidity
of the soil, reduce the soil’s beneficial organism population and interfere
with plant growth. Generally, soil that is considered to be healthy, contains
enough nitrogen-fixing bacteria to fix sufficient atmospheric nitrogen to
supply the needs of growing plants. However, continued use of chemical
fertilizer may destroy these nitrogen-fixing bacteria. Furthermore, chemical
fertilizers may affect plant health.D2 


independent variable of my experiment (i.e. Organic and inorganic fertilizers)
effects all stages of growth of my dependent variable (i.e. Mustard
seeds).  Ironically, using too much of
fertilizers can alter the fertility of soil by increasing the acid levels in the soilD3 . Hence, though fertilizers may
seem to work in the short run, there are high changesD4  that you may not be able to use it
for the longer run as it affects the fertility of the soil and eventually the
growth of the plants. Thus, to prove this thesis, there are three different
concentrations of organic and inorganic fertilizer (i.e. low concentration,
moderate concentration and high concentration) used in order to observe the
trend of growth.

growth rate, germination rate, germination velocity, root length and many other
measures of growth are negatively affected by the increased acidity of soil D5 caused by fertilizers and more
specifically, chemical fertilizers. Hence, through this research paper,
germination without the use of any sort of fertilizer, namely a ‘controlled
germination D6 process’ of a mustard plant is also
to be conducted.


number of seeds will germinate with the use of organic fertilizer initially as
organic fertilizer nutrients release slowly over the course of weeks or months as opposed to
chemical fertilizers that are usually immediately available to plants. D8 However,
on the longer run fewer number of seeds will germinate with the use of chemical
fertilizer as it decreases
the acidity D9 of
the soil depleting its quality and affecting the growth of the plant.

Additionally, without the use of a fertilizer, the growth of the mustard seeds
will be similar to when organic fertilizer is used. However, the number of
seeds germinated might
differD10 .


Could you cite your source for this information?

CXT This is a relevant point, but  D2paraphrase this section
and either add a footnote to cite your source or list your references at the
end of the document.

Cite your source because this is a strong claim.


You might need to focus on a more holistic argument than just acidity, because
pH level may not be the only factor affecting growth of plants. Explore other
effects that fertilizers have on soil and seed germination rate.

Control not controlled. Control group is a set of specimens in which you do not
add any external agents, in this case fertilizers.

Clarify that this is your hypothesis.

You can talk about the rate of release in your preceding arguments instead of
repeatedly going back to soil acidity

Is it decrease or increase of acidity?? You are contradicting yourself here.

Differ in what way?
