Corn stalks are left in the field to serve as mulch during turn-around period. (A. Salaum and R. Gallano)
The technology is practiced in corn farm. It involves the incorporation of stalks and leaves, usually chopped, during the land preparation for the suceeding crop. Corn ears are harvested manually. After harvesting, the stalks are cut and spread on the farm. This provides surface protection to the soil during the turn-around period when erosive rainfall events can occur. After a 2-3 weeks turn-around period, land preparation for the succeeding crop starts. Land preparation can either be by machine or animal. The crop residues are incorporated during plowing which is done twice. The technology is intended to increase organic matter and other nutrients through recycling, improve soil structure and porosity and increase soil water holding capacity. The more common practice done in the past in disposing crop residue is by burning. Residue incorporation has added benefits in that it lessens the emission of gases, particularly carbon dioxide which contributes to global warming.

more nutrient are added
scattered corn stalks hinder plowing
contingent on product prices
reduced cost (no need to haul or burn crop residues)
proof is rapid adoption of the technology by farmers
better water holding capacity
more vigorous growth of crops
long term processs
long term processs
increase infiltration
reduced runoff
no blown ash due to burning
no more burning
