Soil pH

Plant growth is severely restricted because aeration is poor when the soil is wet; in dry conditions, plant-available water is rapidly depleted and the soils become hard and cloddy high soil strength . Many strongly acidic soils, on the other hand, have strong aggregation, good internal drainage, and good water-holding characteristics.

Soil health

In 1978, Swiss soil biologist Dr Otto Buess wrote an essay 'The Health of Soil and Plants' which largely defines the field even today. The underlying principle in the use of the term “soil health” is that soil is not just an inert, lifeless growing medium, which modern intensive farming tends to represent, rather it is a living, dynamic and ever-so-subtly changing whole environment.
