Agriculture & horticulture

The basis of good, productive soil is a good porous crumb structure with an ideal composition of one third soil, one third air and one third moisture. However, on many farms, this basis is far from achieved and we often find extremely dense soil profiles and, varying in depth, even hard, obstructive layers, resulting in a lack of oxygen, bad rooting, disrupted water management and reduced soil strength.

Following on from the work of Johannes Görbing (1877-1946), O. J. Cleveringa (1890-1980) and Johannes Bron (1920-1989) we also use the ‘Spade Test’ (spatendiagnose) developed by Görbing in our soil research in the 21st century. The spade test is a unique, visual observation method with which the plant/soil relationship can be studied, thus contributing to producing ‘living soil’ as the basis of optimum soil fertility and sustainable agriculture.

In the Spade Test, profile pits are dug and special attention is paid to the relationship between the visually observed soil structure and the development of the root systems of plants. This enables us to track down structure defects. The effect of structure defects (e.g. obstructive layers) on the growth of grass and plants is clearly and attractively displayed by such things as root development. Knowledge of the rooting of plants is the basis of healthy agriculture and horticulture.

The Spade Test gives us a faithful picture of the processes going on underground in relation to the growth of the plant above ground.

The BRONCORRECTOR takes the entire structure of soil profiles to a considerably higher level. In particular, dense, obstructive layers regain their porosity and thus allow the passage of water. But the capillary action and air capacity are also improved.

The result is that you have better control over the all-important ‘water management’ so that, in wet periods, the water gradually sinks to the subsoil to supplement the groundwater. In a dry period, the root-bearing layers remain moist due to improved capillary action. The advantage of a good crumb structure and healthy soil is that the plant roots can develop healthily and strongly, resulting in a stronger plant.
