I would consider it a great agricultural advance if someone could formulate a chemical that can be sprayed onto the soil, setting hard enough to resist strong (soil eroding) rain splash and foot-traffic, allowing air and rapid water penetration, blocking light, which is inert so as to have no adverse affect on the chemical or physical properties of the soil when ploughed in after harvest.

Any entrepreneurs out there?

There is a product called Asia Roads. It is a natural enzime used for road construction. Asia Roads is diluted in a water truck and mixed in the soil with a road grader, then the road is graded then compacted with a roller. It becomes harder than soil-cement. If the road needs to be broken up later there is no special disposal issues as with concrete or asphalt. It is used on rural roads, driveways mining roads, airport runways, military roads etc usually with a dual chipcoat top coat, and used for treating local soil for highway sub base to go under concrete or asphalt. Now you have a good excuse to buy a road grader, water truck and vibratory roller and a big chisel plow! (www.asiaroads.net)
