The economic impact on the environment and human health caused by conventional chemical intensive agriculture is causing scientist to re-assess the development of agricultural systems. Pesticides and processed chemical fertilizers have been shown to becausing environmental disruption which will nudermine the resource base on which agriculture production depends. The rise of sustainale agriculture, integrated pest management, organic agriculture, and other forms of alternative agriculture are a result of varmers and researchers searching for new solutions to the problem of food production which does not endanger the all important agriculture are a result of farmers and researchers endanger the all important agriculture resource base. Organic agriculture is one approach which has been developing more quickly in recent years with increasing consumer purchasing power. Organic agriculture has shown itself to be sa or more profitable, and in many cases as productive as conventional agricultural methods on some crops. Further development of organic agriculture, and low-input agriculture will require further modification of policies which overwhelmingly support high imput, chemical intensive agriculture.

This study is investigated by experimental method and FEM about the effect of notch root radious(ρ) on the fracture of GFRP. The smaller ρshowed the fracture behavior which was mainly caused by the propagation of the stable crack, but the fracture behavior in the larger ρwas mainly caused by the spread of damage. The experimental value of the nominal stress could be estimated by FEM simulation and the load-displacement curve could also be drawn. According to the results simulated damage zone by FEM, as the ρis smaller, the damage begin at low stress.
