Apples

How we can help

Our biological programme for apple orchards ensures rapid orchard establishment, which means you will harvest your first crop sooner. This is due to the programme improving the soil, which creates bigger, better shaped trees with more extensive root systems.

Healthier trees also mean better quality fruit (including dry matter percentage, colour and flavour) and optimal yields. Other benefits include higher nutrient uptake by the tree, and more resilient plants during environmental stress, and longer fruit storage.

Our soil programme also benefits the orchard by remedying soil compaction problems by repairing soil aggregate formation and increasing carbon sequestration which helps with soil aeration and drainage.
