Soil health refers to the capacity of soil to be used productively without harming future productivity, the ecosystem or the environment. This approach emphasises the integration of biological with chemical and physical characteristics of soil quality that would have an impact on farming’s profitability and on the environment.
To maintain and improve soil health, ZZ2 uses compost and manure, compost teas, effective microbes (EM), long dormant periods (of up to seven years) and crop rotation. ZZ2 works closely with the Cornell Soil Health Team (USA) that developed indicators for change in soil status. We also collaborate with Cornell University, the Universities of Stellenbosch, Pretoria and Limpopo to investigate new prospects of using biological means to improve soil health.
The carbon content of the soil (important for microbial life and diversity) is increased and sustained through rotation and limited tillage.
The use of pesticides is contained because of its negative impact on microbial diversity.
Soil erosion is not allowed at all. All fields, orchards and roads are governed by a strict protocol of contours and drainage systems.
