Abstract

This publication describes a fertilizer comprising at least one basic L-amino acid. The fertilizer is a solid composition wherein a substantial portion of the basic L-amino acid content is present as a monophosphate thereof. The term "a substantial portion" means that the fertilizer is comprised of a monophosphate of at least one basic L-amino acid as its predominant source of organic nitrogen. Thus, small amounts of other phosphates may be present, such as polyphosphates remaining from the preparation.

Fertilizer compositions having amino acids included

Introduction

Methods of improving soil and/or growth conditions have in principle been applied

since the first days of agriculture and horticulture. Starting with a very limited 5

understanding of mechanisms, it was recognised that the waste from the household

animals such as cows improved the growth of crops in the fields. As nitrogen,

potassium and phosphorus were identified as the key components required to

efficiently fertilize the soil, commercial preparations became widely available and the

principle of more is less was generally applied for decades, resulting in the by now 10

well-known over fertilization effects. While preparations including nitrogen,

potassium and phosphorus together with various other mineral nutrients still constitute

the standard in most plant culture, research is continuously improving with regard to

the refinement of fertilizer compositions to provide plants with what is needed for their

optimal growth. Specifically designed compositions for certain plants have been 15

developed, and different formats such as liquids and dry preparations are also provided

in order to balance a desired growth, feasibility of application and a minimal

environmental impact.

An ongoing challenge in coating technology is to provide for a release which is 20

extended to a prolonged period of time, at a rate which is adapted to the needs of the

cultured plant.

New fertilizer composition

This publication describes a fertilizer comprising at least one basic L-amino acid. The 25

fertilizer is a solid composition wherein a substantial portion of the basic L-amino acid

content is present as a monophosphate thereof. The term “a substantial portion” means

that the fertilizer is comprised of a monophosphate of at least one basic L-amino acid

as its predominant source of organic nitrogen. Thus, small amounts of other

phosphates may be present, such as polyphosphates remaining from the preparation. 30

The fertilizer comprises a monophosphate of at least one basic L-amino acid, and no

other phosphate(s).

The basic L-amino acid used may be L-arginine; L-lysine; or L-histidine, which may

include modified forms thereof, provided that they have maintained the herein 5

discussed properties for providing nitrogen to seeds or plants. Basic L-amino acids are

available from commercial sources. The basic L-amino acid may for example be

arginine, and the fertilizer may comprise arginine monophosphate optionally together

with additional nutrient(s) and/or binder(s), as discussed below. Monophosphates of

basic L-amino acids are easily prepared following well known methods. 10

The herein described fertilizer may further comprise at least one binder, which is well

known in this area. Binders may e.g. comprise mineral(s) and/or natural or synthetic

polymers, such as sugars or carbohydrates; salts; or minerals. Binders such as

polyvinyl alcohol (PVA) or calcium-containing salts and calcium-containing mineral...
