Sample H. Remarks and recommendations.

This is a yellowish grey sandy loam, the sub-soil being very slightly heavier than

the top-soil. The water-holding capacity is fairly good. Soluble salts are low in amount.

The reaction of the soil is strongly acid.

The amounts of most of the mineral plant food constituents present are low,

especially phosphoric acid. Lime also is deficient in amount, whilst the potash may be

just sufficient for crop growth for the present. Although the percentage of nitrogen is also

rather low, the ratio of carbon to nitrogen is about normal.

The soil needs manuring with lime and phosphoric acid, whilst dressings of

potash and nitrogen would probably be advantageous.
