Four experiments were set up in a greenhouse. To search for any micronutrient element (s) that control plant growth of crop grown on subsoil of the Kamphaeng Saen Soil Series. There were (1) addition of one element as solid chemical, (2) addition of complete but one element as soil chemical; (3) spraying of one element solution; and (4) spraying of complete but one element solution. Prosol millet was used as indicator crop. All experiments showed that there was no problem concerning any micronutrient elements in growing plants on subsoil of the Kamphaeng Saen Soil Series. Fresh pressed cake, saw dust, rice husk and cattle manure at 50% (volume) were incorporated into 20 cm depth of subsoil of the Kamphaeng Saen Soil Series and supplied with 10-10-10 kg N-P2O5-K2O per rai as basal fertilizer and 8 kg N per rai as top dressing fertilizer. The supant cane was used as indicator crop. It was found for one year old cane (1982) that incorporation of fresh cake and cattle manure could increase the number of canesper stalk and cane weight up to more than twice and more than 21/2 times, respectively from no addition of organic substance to the soil. Fresh pressed cake was incorporated at 0, 12.5, 25% by volume of 30 cm soil to the subsoil sample of the Kamphang Saen Soil Series by fraction of 0.30 cm soil column and 30-60 cm soil column in cement tanks. Q 83 cane was used as indicator crop. Incorporation of fresh pressed cake at 25% to 30-60 cm soil and to 0.30 cm soil column also incorporated at 12.5 or 25% could increased cane yield during the first year crop (1981) but did not have an effect on yield for thew first ratoon crop (1982)
