The plot P50 was cultivated with only chemical fertilizer, P51 was lying fallow with only wastes added, and P52 was cultivated and fertilized by both ways. After 14 months the soils were analyzed again. The plots texture was found to be sandy loam whose organic matter widely increased, and the pH shifted from acidic to rather neutral.
