Soil is composed of many particles of varying sizes. Soil scientists have classified soil particles into three major groups: sand, silt and clay. Sand particles are the largest and tend to hold little water but allow good aeration. Clay particles are very small in size and tend to pack down so that water does not drain well and little or no air can penetrate. Silt particles are medium sized and have properties in between those of sand and clay.

A loamy soil, then, is one that combines all three of these types of particles in relatively equal amounts. Loamy soil is ideal for most garden plants because it holds plenty of moisture but also drains well so that sufficient air can reach the roots. The best ratio is 20% sand, 40% clay and 40% organic material in silt... (Thanks to Purdue University Agricultural Science).

i dont know how much you need but the easiest and best way is to buy john innes composts.
these come in numbers 1,2, and 3, these refering to various types of content.of mix.
john innes is in fact a formulae and when made has also been sterilised, very important.
at this time of year you will be able to buy some bags on offer, bowers is the best brand.
i am not knocking making your own but j. innes is the real deal. look up on google if interested.
trust this helps.
