Problems solved by technology

[0023] Preferably no more than 20% of the powder particles will have a particle size of less than 150 μm (also referred to herein as “fertilizer dust” or “dust”), since having more than 20% of the powder particles with a particle size of Too low for an efficient process, e.g. causing machine vibrations, increased porosity of finished product, high incidence of downtime, etc.

Abstract

According to some demonstrative embodiments, there is provided herein a spherical fertilizer granule having a specific gravity of more than 1.94 g / cm2 and less than 3% porosity.

Description

technical field [0001] The present invention relates to fertilizers derived from any material of natural or synthetic origin, which are applied to soil or plant tissue to supply one or more phytonutrients necessary for plant growth, in particular to fertilizers having the shape of spheres. Background technique [0002] For proper growth, plants require nutrients that are normally found in the soil (nitrogen, potassium, calcium, zinc, magnesium, iron, manganese, etc.). Fertilizers are sometimes required for desired plant growth as these enhance plant growth. [0003] This plant growth is met in two ways, traditionally with additives that provide nutrients. The second mode in which some fertilizers work is to enhance the efficiency of the soil by altering its water holding capacity and aeration. Fertilizers typically provide three main macronutrients in varying proportions. [0004] Nitrogen (N): leaf growth; [0005] Phosphorus (P): the development of roots, flowers, seed...
