LENZ Chemical limitations to plant growth

LENZ Chemical limitations to plant growth

Understanding the chemical factors that limit plant growth is key to looking after your whenua and boosting its productivity. This interactive map tool helps you see how soil nutrients and other chemical properties vary across New Zealand, influencing what plants will thrive where.

You can explore things like soil pH, nutrient levels, and other chemical conditions that might limit your pasture or crops. This gives practical insights for managing fertiliser wisely, improving soil health, and supporting healthy ecosystems and can help you make better decisions about your whenua.
