Embodiment 1

[0030] Urea nitrate was dissolved in water to prepare aqueous solutions with total nitrogen concentrations of 140 ppm, 280 ppm and 420 ppm. As a control, urea was dissolved in water to prepare an aqueous solution with a total nitrogen concentration of 140 ppm.

[0031] A cultivation test was carried out using Komatsuna "Xia Lotte" (Takii Seedling Co., Ltd.). The test period was 24 days from early November to early December. To Neubauer pot (Neubauer pot) (inner diameter 11.3cm, height 6.5cm), fill 500ml culture soil (combination love dish No. 1 (kumimei love dish No. 1), manufactured by Katakura Chitsukarin Co., Ltd.), and add the above preparation Each urea nitrate aqueous solution or urea aqueous solution, so that the soil moisture content in the pot is 50-60%. 20 komatsuna seeds were sown in each pot, and the ground surface was watered with a watering can as needed until germination. After germination and cotyledons unfolded, each aqueous solution of urea nitrate and aqu...

Abstract

A liquid fertilizer for soil cultivation that realizes use of urea nitrate substantially not having been utilized as a fertilizer to date and attains exertion of strikingly enhanced fertilizer effects. There is provided a liquid fertilizer for soil cultivation comprising urea nitrate wherein the content of urea nitrate is in the range of 0.006 to 1.2 wt.%. By application of this liquid fertilizer for soil cultivation onto the soil surface and/or in the earth while avoiding direct contact with the leaves of germinating crops, crop cultivation can be carried out without phytotoxicity.

Description

technical field [0001] The invention relates to a liquid fertilizer for soil cultivation and a method for cultivating crops. Background technique [0002] For a long time, people have been studying the use of urea nitrate as a nitrogen fertilizer, but urea nitrate is a strong acidic substance. When solid urea nitrate such as powder or block is used, it will cause phytotoxicity at the position in contact with the crops. achieve practicality. [0003] Patent Document 1 teaches the use of a nitrate aqueous solution of urea as a foliage treatment agent. However, since urea nitrate is used to treat the stems and leaves of crops, phytotoxicity occurs, and thus urea nitrate cannot be effectively used as a fertilizer in practice. [0004] Patent Document 1: Japanese Unexamined Patent Publication No. H11-158010 Contents of the invention [0005] The object of the present invention is to provide a liquid fertilizer for soil cultivation which can show a particularly excellent fert...
