免耕地块的谷物产量与传统耕作处理的谷物产量相当。免耕处理比耕地具有更高的有机质含量，并且通过控制土壤侵蚀，淤泥和粘土含量更高。两种耕作处理的表层土壤持水能力和水分释放特性存在显着差异。免耕地块中最高土壤温度的降低和有利的湿度状况刺激了生物活性，例如蚯蚓。虽然肥料对耕地没有反应，但灌溉可能由于严重的淋滤损失而产生负面影响。免耕技术有可能在高度易侵蚀的浅层热带土壤上实现连续耕作。
The grain yields in the no-tillage plots were equivalent to those of conventionally plowed treatments. No-tillage treatments had higher organic matter content and, by controlling soil erosion, the silt and clay content than the plowed plots. The water holding capacity and moisture release characteristics of the surface soil horizon were significantly different for the two tillage treatments. A decrase in the maximum soil temperature and favourable moisture regime in the no-tillage plots stimulated biological activity e.g. earthworms. While the fertilizer had no response on the plowed plots, irrigation had a negative effect due probably to severe leaching losses. No-tillage techniques have a potential in achieving continuous cultivation on otherwise highly erodible and shallow tropical soils.
