Three integrated services that turn complex soil and plant data into simple, profitable farm management decisions.
How It Works
We collect soil and leaf SAP samples from your orchard or pasture to establish a precise biological and nutritional baseline.
Samples are tested for microbial biomass, F:B ratio, and full SAP nutrient profiles through accredited laboratories.
We translate raw lab data into clear, jargon-free reports that show exactly what your soil and plants need right now.
Every report includes specific biological interventions, input recommendations and timing schedules you can act on immediately.
Pillar 1
Your soil biology is the foundation of everything. Without knowing your Fungal-to-Bacterial (F:B) ratio and total microbial biomass, any regenerative strategy is guesswork.
We track the key biological indicators that determine whether your soil can support high-performing tree crops or perennial pastures:
Tree crops like macadamias, avocados and citrus evolved in fungal-dominant ecosystems with F:B ratios of 2:1 to 5:1. Most South African commercial soils sit at 0.1 to 0.3—a bacterial-dominated state caused by decades of tillage, synthetic fertiliser and calendar fungicide programmes. This mismatch is the root cause of chronic nutrient deficiencies, rising pest pressure and escalating input costs.
We recommend baseline testing followed by seasonal monitoring. This gives you a clear trajectory—you can see the biology shifting in response to your management changes, not just hope it is working.
Pillar 2
Traditional soil tests tell you what is in the ground. SAP analysis tells you what the plant is actually absorbing right now. That distinction is the difference between guessing and knowing.
SAP (plant sap) analysis measures the concentration of nutrients circulating inside your crop's vascular system at the moment of sampling. It captures real-time nutritional status—what the plant has taken up, not what is theoretically available in the soil.
Raw SAP data from the laboratory is noisy and difficult to read. Nutrient interactions, antagonisms and synergies mean that individual numbers in isolation can be misleading. Our interpretation service translates those numbers into a clear nutritional picture:
When you know exactly what the plant needs, you stop broadcasting blanket fertiliser applications. Targeted interventions based on SAP data typically reduce total fertiliser spend while simultaneously improving crop nutrition and resilience.
Pillar 3
Data without action is wasted money. The third pillar of the Succession Soils Method turns your soil biology and SAP analysis results into concrete, implementable field interventions.
Every assessment cycle delivers a clear, prioritised action plan tailored to your specific crop, soil type and growth stage:
The key is sequencing. We do not ask you to make dramatic, all-or-nothing changes. Instead, we phase biological interventions alongside your existing programme, using SAP data as a safety net. As the biology builds, we systematically reduce synthetic inputs—only when the data confirms the soil can take over. This is how you avoid the yield dip that destroys most regenerative transitions.
Our management protocols are specifically designed for subtropical tree crops (macadamias, avocados, citrus) and perennial pastures in KwaZulu-Natal and Mpumalanga. We understand the unique soil chemistry challenges of these regions, including acid soils, aluminium toxicity and high summer rainfall.
Common Questions
Pricing depends on the size of your operation and the number of sampling points required. Contact us for a tailored quote. Most commercial orchards start with 4–8 sampling points across representative blocks.
We collect leaf SAP samples at specific growth stages, send them to an accredited laboratory, then provide you with a detailed interpretation report. The report explains what your plants are absorbing, identifies hidden deficiencies and antagonisms, and gives you precise corrective input recommendations with rates and timing.
No. The Succession Soils Method is specifically designed to avoid abrupt changes. We phase biological interventions alongside your existing programme and only reduce synthetic inputs when SAP and soil data confirm that the biology can take over. This is how we avoid the yield J-curve.
The F:B ratio measures the relative biomass of fungi versus bacteria in your soil. Tree crops and woody perennials perform best in fungal-dominant soils (F:B of 2:1 to 5:1). Most commercial agricultural soils in South Africa are heavily bacterial-dominant (0.1 to 0.3), which limits the soil's ability to cycle nutrients, hold water and suppress disease.
Soil biology responds to management changes within a single season. Measurable shifts in the F:B ratio are typically visible within 12–24 months. Input cost reductions often begin in the first year as targeted SAP-based interventions replace blanket fertiliser applications.
Our primary focus is KwaZulu-Natal and Mpumalanga, where we have deep knowledge of local soil chemistry and climate conditions. However, we can consult with tree crop and pasture operations in other subtropical regions of South Africa on a case-by-case basis. Contact us to discuss your situation.
