Patchy Pasture or Crop Growth
Uneven growth across fields
Many growers notice areas of pasture or crops that are thinner, slower, or weaker than surrounding areas. Even with consistent fertiliser, irrigation, and management, growth can remain patchy.
Patchiness is a common symptom of underlying system issues — not just poor management. Understanding the causes is the first step toward consistent, productive growth.
Common causes of patchy growth
Soil variability
Differences in soil texture, structure, and fertility can cause uneven nutrient and water availability across a paddock.
Low soil biology
Microbes help convert nutrients into plant-available forms. Areas with low microbial activity often show weaker growth.
Nutrient inefficiency
Even when fertiliser is applied uniformly, nutrients may not be fully available in all areas due to leaching, volatilisation, or low carbon and microbial support.
Plant stress
Drought, waterlogging, pests, or disease can reduce growth in specific zones, creating patchiness.
How to improve consistency
Addressing patchy growth usually involves improving the system as a whole:
Support soil biology to improve nutrient cycling and root access
Increase organic carbon where possible to feed microbes and retain nutrients
Manage environmental stress and soil conditions (drainage, compaction, irrigation)
Ensure fertiliser is applied efficiently, in ways plants can use it fully
Where our products fit (practical tools growers use)
Our products don’t replace fertiliser, but they help improve growth consistency by supporting soil function and nutrient efficiency:
Lazerhume
Enhances microbial activity, helping nutrients become more available across the paddock.
Restore
Adds extra system support in soils under pressure to improve uniform growth.
Optimise iO
Liquid platforms that support microbial activity and help stabilise nutrients in areas that struggle with patchiness.
Turbo N
Supports consistent nitrogen response, which can reduce uneven growth caused by inefficient nitrogen uptake.
These tools are most effective when used as part of a broader system, not as stand-alone fixes.
When this approach won’t help
Patchiness may persist if:
Soil compaction or drainage issues are unresolved
Soil fertility is extremely uneven or deficient
Chronic plant stress from pests or disease isn’t addressed
System improvements should always begin with basic soil and crop management.

Frequently asked questions
Will these products make growth uniform immediately?
Improvements take time as soil biology and system function recover, but visible benefits can be seen within a season.
Do I need to change fertiliser programs?
Not necessarily — these tools complement existing programs by improving nutrient uptake and efficiency.
How do I identify the cause of patchy growth?
Look at soil, plant stress, fertility, and drainage. Often multiple factors combine to create uneven growth.
Key takeaway
Patchy pasture or crop growth is rarely a single issue. By supporting soil biology, nutrient efficiency, and plant resilience, growers can achieve more uniform, productive, and resilient fields.
