Fast Facts


Crop yield is greatly influenced by plants being able to access the required amount of nutrient. They need to be able to access every nutrient that they require, and in a balanced and timely way.

Providing information so that Farmers and Growers can not only understand a crop’s growth stages, but also the optimum timing periods for fertiliser application, and the product best designed to deliver the best yields and outcomes, is an important focus for RLF.

The Crop Guides Growth Stages information that follows depends wholly on the RLF products identified as being the most appropriate. Our products are based on world-leading science and technology that ensures that nutrients are delivered directly to the plant. By following the regimes recommended by RLF, many benefits can be achieved for Farmers and Growers around the world.

The Fast Facts that accompany this information seek simply to give some quick background perspective to the relevance and the importance of this crop as it plays its part in providing the world with the food that it needs.
