There are two types of agricultural crop residues<span>. </span>Field residues<span> are materials left in an agricultural field or </span>orchard<span> after the crop has been </span>harvested. These residues include stalks and stubble (stems<span>), </span>leaves<span>, and </span>seed<span> pods. The residue can be ploughed directly into the ground, or </span>burned<span> first. Good management of field residues can increase efficiency of </span>irrigation<span> and control of </span>erosion<span>. </span>Process residues<span> are materials left after the crop is processed into a usable resource. These residues include </span>husks<span>, seeds, </span>bagasse<span>, </span>molasses<span> and </span>roots<span>. They can be used as animal </span>fodder<span> and </span>soil amendment<span>, fertilizers and in </span>manufacturing<span>.</span>
