Environmentally friendly, labour saving and cost effective 

Our world is changing quickly, customers are always looking for the best solutions and high quality grass seed products. However they are also looking to reduce inputs of herbicides, fertilisers and water to preserve our environment.

The R&D department of DLF has been working on products that need lower inputs for a long time. The aim of which was to combine the best grass seed genetics with all the nutrients needed by a seedling in a single coating, so as to improve the establishment of the plant but also reduce inputs and costs. Our first generation nutrient seed coating was iSeed.

Following significant continued product development & substantial laboratory, greenhouse and user trials, we are proud to introduce the 4th generation of nutrient seed coatings ProNitro which delivers faster establishment and represents even greater value for money.

A unique solution 

ProNitro  is a patented seed coating that focuses on improving nutrient utilization during the early stages of plant growth. Typical nitrogen content found in other commercial products is 1-2%, with the effects often being negligible. The ProNitro coating contains 15% nitrogen, a combination of both fast acting and slow release N. As the fertiliser is coated onto the seeds, the germinating and developing seedling receives the benefit, not the surrounding plants. The roots and shoots grow rapidly and the seedlings become strong and vigorous. This improves the use of all the available soil nutrients and decreases nutrient losses into the environment by fixation or leaching.This is particularly important when overseeding into a competitive sward. The nitrogen uptake with ProNitro is up to four times efficient compared to broadcast applied ordinary fertilisers.
