N ORDER to produce a ton of dry hay on anacre of land it is necessary that the growinggrass pump up from that acre approxi-mately 500 tons of water. In order tosupply this enormous quantity of water,the soil must not only be in condition toabsorb and hold water well, but it must be porous enough topermit water to flow freely from soil grain to soil presence of large quantities of decaying organic mat-ter (humus) adds enormously to the water-holding capacityof the soil. One ton of humus will absorb two tons of wa-ter, and give it up readily to growing crops. Not only that,but the shrinkage of the particles of decaying organic mat-ter and the consequent loosening of soil grains keep the soilopen and porous. Furthermore, humus of good quality is exceedingly richin both nitrogen and mineral plant food. The maintenanceof fertility may almost be said to consist in keeping the soilwell supplied with humus. The first step in renovatingworn-out soils is to give them an abundant suppl
