This problem involves consideration as to the effect of external conditions such as light, heat, moisture, altitude, manuring and other cultural matters, and as is obvious, such considerations may, and do, vary greatly with different plants. Such considerations are to some extent within the scope of the knowledge and skill of the well-trained farmer and the careful distiller. But there are other considerations of a much more abstruse character to be taken into account, and here only the chemist can undertake the necessary investigations. The questions which present themselves for solution are, broadly, some such as the following —... 

Stored solid manures acts as a source of N20 production/consumption and emission. Covering heaped manure shows reduction in NH3 emissions but has no effect on N20 emission, while other studies showed that both were reduced. The addition of chopped straw reduced N20 emission by 32% from the small scale of cattle manure. [54], Slurry or liquid manure with no cover showed negligible N20 release, while slurry with straw cover might act as a source of emission [55]. N20 emission occurs following manure application to soil [56], Various factors that affect N20 release from soil include (i) type of manure, (ii) soil type, (iii) manure composition, (iv) measurement period, (v) timing of manure application, (vi) amount of manure applied, and (vii) method of application.
