Chemicals accumulate in surface soil due to soil compacion 
If antibiotics, chemical pesticides, herbicides and fertilizers that are used
every year were diffused and decomposed in soil, the problem would not be as
serious. Unfortunately, the fact is that they actually accumulate in the 15 cm (6
in) belt below the surface because of a layer of compacted soil. Use of heavy ma-
chinery is a direct cause of soil compaction. Tractors are the main culprit. e
heavy wheels of a tractor press down on the soil and their effect can be meas-
ured as deep as 7 meters (23 ft). Repeated use of heavy vehicles turns the soil

layer at 15 cm (6 in) depth rock-hard. Because of this compacted soil layer, the
agricultural chemicals cannot penetrate deep into the soil and enter a break-
down cycle. Instead they will linger at the 15 cm (6 in) sub-surface level after
water has evaporated. is residue is highly detrimental to crop roots. JADAM
recommends you to stop using heavy tractors but use light vehicles instead and
minimize the use of chemical material. Come down from the heavy machines.
If you have to use tractors, then take the extra care so that the wheels will not
run over crop-growing area.

Elderly people will remember that just a few decades ago it was common to
grow pepper and harvest until the autumn frost. e farmers of old days did
not have microorganism products, synthetic fertilizers or get education on sci-
entiic pepper cultivation like their modern counterparts, however, they easily
grew wonderful peppers. Today, farmers have an abundance of products to
choose from; they have abundant opportunities to get education. Ironically, not
many farmers nowadays manage to grow and harvest pepper until the frost. e
situation has become such that some farmers would say that pepper is the most
difficult crop to grow on open ields. But for our ancestors, pepper was one of
the easiest. Why did it become like so? Is it because canker and other soil-borne
disease became rampant? en, we must ask again, why did it become rampant?
