A by-product of cotton manufacturing, cottonseed meal as a fertilizer for the garden is slow release and acidic. Cottonseed meal varies in formulation slightly, but is generally made up of 7% nitrogen, 3% P2O5, and 2% K2O.
Bone meal is also useful for balancing out other high nitrogen, organic soil amendments. For example, rotted manure is an excellent source of nitrogen but it tends to lack significant amounts of phosphorus.

The Uni-Mill under-driven models are designed with an optimal, spacer-less gap (to avoid metal-to-metal contact); this offers a major benefit compared with over-driven conical mills where the distance between the screen and impeller has to be set manually using spacers. This makes tooling changes on under-driven mills faster and easier,
Nitrogen must be kept at higher pressure than CO 2, making N 2 tanks heavier and more expensive. Nitrogen gas has become the inert gas of choice for inert gas asphyxiation, and is under consideration as a replacement for lethal injection in Oklahoma.
Nitrogen dioxide is the chemical compound with the formula NO 2.It is one of several nitrogen oxides. NO 2 is an intermediate in the industrial synthesis of nitric acid, millions of tons of which are produced each year which is used primary in production of fertilizers.At higher temperatures it is a reddish-brown gas that has a characteristic sharp, biting odor and is a prominent air pollutant.
A high-energy ball mill operated at room temperature under a nitrogen gas flow can be successfully employed for preparing a single phase of NaCl structure TiN powder. The as-milled powders were consolidated into bulk samples, using a PAS method.
