Dr Forest’s 5-4-3 fertiliser is made from all natural ingredients:

Our fertiliser is valued for its percentage of organic matter rather than The NPK content.

Sustaining and improving soil makes good sense. Often the soil organic matter content is diminished due to intensive growing and the use of herbicides and synthetic fertilisers.

Good soil management can improve the nursery growers profits by reducing plant disease, improving plant growth and providing a stronger end-product that has much more chance of survival than the average garden centre plant.

Why our High Organic Matter Fertiliser can replace a traditional fertiliser.

Most organic matter added to a soil decomposes over a few years as animals and micro-organisms feed on it. This process releases nutrients for the plants to grow.

During this period of decomposition organic matter is often called the active fraction and this fraction can quickly change with changes in soil management.

Most of the remaining organic matter does not break down so easily – it can take many years. This more stable matter is known as humus. Both active and stable soil organic matter make important contributions to binding soil particles together into stable aggregates that give soil its crumb-like structure. They improve a soils workability, root penetration, and water and nutrient holding capacity. Soil organic matter can be both financially and environmentally beneficial to a nursery enterprise.


Properties of Fertiliser:

  • Water and air enter and circulate more freely in the soil.
  • Improved root penetration
  • Water-logging and surface water is reduced which in turn reduces soil erosion
  • Plant growth and establishment benefit from improved water and nutrient availability.
  • Soil workability improved which cuts cultivation costs.
  • The soil is more resistant to compaction
  • Storage and supply of plant nutrients –N P K and micro-nutrients is improved.
  • Cation exchange capacity which governs nutrient availability for plant uptake is improved
  • Soil needs less lime because of improved soil Ph buffering.
  • Carbon and energy are available for the soil micro-organisms that cycle nutrients and fight disease.
  • Contaminants are bound up reducing the negative environmental effects of pesticides, heavy metals and other pollutants.
