Agricultural Materials

Abstract

PROBLEM TO BE SOLVED: To obtain an agricultural material in the form of a nonwoven fabric carrying a fertilizer excellent in the so-called easy splitting properties represented by tear strength, good in compatibility with soil and facilitating fertilizer application operations by supporting a fertilizer response regulating type fertilizer between plural specific staple fiber nonwoven fabrics. | | SOLUTION: This agricultural material is obtained by supporting a fertilizer response regulating type fertilizer between at least two staple fiber nonwoven fabrics. One of the staple fiber nonwoven fabrics comprises cellulosic fibers and thermally fusible fibers and is a first staple fiber nonwoven fabric fused by the thermally fusible fibers. The other staple fiber nonwoven fabric comprises the cellulosic fibers or the cellulosic fibers and the thermally fusible fibers and is a second staple fiber nonwoven fabric fused with the thermally fusible fibers or unfused therewith and having a larger specific volume than that of the first staple fiber nonwoven fabric. | | COPYRIGHT: (C)2000,JPO&Japio | | SUBJECT of the Invention | | The agricultural materials of the nonwoven fabric field which can reduce a fertilizer|manure application operation|work, plant growth management, etc. are provided using fertilizer effect control type|mold compound fertilizer. | | Furthermore, there exists an intensity|strength, and also tear is easy and provides the fertilizer of the shape of a nonwoven fabric which was excellent in the conformability|familiarity to soil. | | PROBLEM to be solved | | They are the agricultural materials which carry|supported the fertilizer effect control type|mold fertilizer to at least 2 sheet(s) of staple fiber nonwoven fabric, | | Comprising: | | A cellulosic fiber and a heat-fusible fiber mix this staple fiber nonwoven fabric, | | And the 1st staple fiber nonwoven fabric melt|fused for this heat-fusible fiber, a cellulosic fiber or this cellulose fiber, and a heat-fusible fiber mix, | | And agricultural materials characterized by the specific volume consisting of a 2nd staple fiber nonwoven fabric which is large from said 1st staple fiber nonwoven fabric.
