Embodiment 1
[0047] The urea nitrate of 10 parts by weight and the calcium hydrogen phosphate of 10 parts by weight (the particle diameter is 10% by weight at the content below 200 meshes) utilize Shinagawa mixer (manufactured by Dalton company) to fully mix to obtain a solid fertilizer composition (hereinafter referred to as "solid fertilizer"). Fertilizer Composition 1").
Embodiment 2
[0049] Use 10 parts by weight of urea nitrate and 10 parts by weight of calcium hydrogen phosphate (the particle size is 58% by weight at a content below 200 meshes), carry out the same operation as in Example 1, and obtain a solid fertilizer composition (hereinafter referred to as "solid fertilizer"). Composition 2").

Abstract
The present invention provides a solid fertilizer composition comprising urea nitrate and calcium phosphate; and a liquid fertilizer composition comprising urea nitrate and calcium phosphate both dissolved in water. These fertilizer compositions are fertilizers capable of feeding nitrogen, phosphoric acid and calcium which are crucial for the growth of plants, excelling in storage stability, and when dissolved in water, would not generate phosphate precipitates. These fertilizer compositions are suitable for use in a nutrient solution cultivation method, and, for example, the liquid fertilizer composition is applied to the stems and / or leaves of plants.
Description
technical field [0001] The present invention relates to fertilizer compositions, methods for their manufacture and methods for their use. Background technique [0002] In order to supplement the ingredients necessary for the growth of plants such as crops and flowers, as fertilizers, compound fertilizers that are a balanced mixture of various ingredients are generally used. In the case of direct fertilization in a solid state, plants can use the nutrients dissolved from the water in the soil, but there are excessive or insufficient nutrients, local differences in the concentration of fertilizers that cause adverse effects on crops, and salt accumulation. Obstacles to continuous cropping, fertilizer components flowing into groundwater and river water, etc. Therefore, fertilizers in the form of an aqueous solution that can easily supply essential components to plants are also generally used. This kind of fertilizer is called liquid fertilizer, and it is especially used in th...
