Description
Various vegetation experiments by soy beans and corns were made for the purpose to utilize the waste liquor from pulp mills as the soil improvement materials. The results were as follows :
1. The most suitable application of the waste liquor to the soil must be done 1-2 weeks before seeding, and the later application delayed the germination of the crops.
2. The waste liquor was especially effective for the volcanic soil, and effective for the loam soil, from the view point of soil texture.
3. The waste liquor has the same or more soil-improving effect, compared with compost.
4. About 500kg application of the waste liquor for 10 ares is considered most suitable for the growth of plant.
