Loam soi

  • Most garden soils are loam soils.
  • This is an ideal growing soil with optimum balance of sand, clay and humus.
  • In reality the perfect loam rarely exists. Most types of loam are either sandy or clayey.
  • The best loam is a rich, dark brown soil, made up of between 50 and 60 percent of sand particles and about 30 percent of clay.
  • The other constituent of loam is humus, the valuable organic compound formed by decayed vegetable and animal material.

Only a few bog plants prefer a clay soil, while most of the commercially grown flowers cannot be grown on clay soil because of poor drainage. A perfect garden soil consists of 1/4th clay, 1/6th humus, ½ sand and ½ lime. But there is hardly any soil which is ideal or perfect to this extent, but many of the loamy soils come very near to this characteristic. A sandy soil is not suitable for growing most of the commercial flowers, firstly, because it has got a very poor water holding capacity and secondly, these soils lack sufficient nutrients.
