ABSTRACT
The use of seed cake, obtained after the extraction of oil, particularly that of non-edible seed, as a manure is well known in agriculture. The use of neem cake has also been recommended for this purpose. Keeping in view the importance of this in agriculture, the Indian Standards Institute (Anonymous, 1977) has given specification No. 8558 for neem cake, for manuring, which is as follows:
• Maximum moisture (percent by mass) 10% • Maximum water soluble organic nitrogen on moisture free basis (percent by mass) 2.
