Pome fruits

A balanced fertilization program for pome fruits is essential to obtain a high yield of good quality and good storage properties

Basic Information

Pome trees are very demanding in plant nutrients. The soil for cultivation should be fertile with a good water holding capacity and aeration, preferably with a neutral pH. In order to ensure a regular high yield, it is necessary to regulate tree growth through pruning, as this will have a positive impact on the size and color of the fruits.

Important instructions for use: If several products are mixed while using our product, unforeseen reciprocal effects may occur. It is not possible to foresee all conditions that can occur in practice (e.g. temperature, kind of water, crop protection agents). Therefore, it is highly recommended to test the compatibility and the application of the intended products on a small scale first. We disclaim any responsibilities for damages which may ensue from interactions based on mixtures – especially – with other products, crop protection agents, plant protection products or fertilizers and/or from unusual conditions (temperature, kind of water, etc.).

Detailed Description

The fertilization of pome fruits strongly depends on the age and phenological stage of the tree. In order to achieve an effective fertilization, it is important to know the available nutrients of the soil, so a soil analysis can provide the needed information.
Major parts of nitrogen (N), phosphate (P) and potassium (K) are applied in spring, mainly with granular SOP based NPK fertilizers, as it is crucial to supply the correct quantities of nutrients so that they are available during flowering. Calcium is also a very essential nutrient for the stability of the fruit’s cell walls, and it must be available for the tree after flowering until harvest. Calcium also has a strong impact on the fruit storage properties; it is most effective as a foliar application.

Zinc, boron, manganese and iron are the most important micronutrients for pome trees (foliar application).
Biostimulation, which is mainly used to alleviate the stress effect, has also a positive impact on the fruit quality and should be applied foliar.
For planting we recommend Basacote® Plus 6M/9M. Blaukorn® or NovaTec® as granular fertilizers are used in the stage of sprouting and bud development. For fertigation systems we recommend Hakaphos® or NovaTec®Solub. Trace elements can be given with foliar application, e.g. with Fetrilon® Combi. The biostimulant Basfoliar® Kelp SL can be appliacted during vegetative growth and fruit development.
