VALUE<br />
This is a comparis<strong>on</strong> between the crop yield from obtained<br />
from MANURE applicati<strong>on</strong> and that from INORGANIC<br />
FERTILISER. The proporti<strong>on</strong> <str<strong>on</strong>g>of</str<strong>on</strong>g> MANURE TOTAL NUTRIENT<br />
c<strong>on</strong>tent equivalent to applicati<strong>on</strong> <str<strong>on</strong>g>of</str<strong>on</strong>g> INORGANIC FERTILISER<br />
applied according to best practice. It takes into account the<br />
facts that<br />
a) <strong>on</strong>ly a proporti<strong>on</strong> <str<strong>on</strong>g>of</str<strong>on</strong>g> the nutrients c<strong>on</strong>tained in MANURES<br />
are in forms available for PLANT UPTAKE<br />
b) proporti<strong>on</strong>s <str<strong>on</strong>g>of</str<strong>on</strong>g> the nutrients in MANURES, especially<br />
nitrogen, may be lost (e.g. through AMMONIA<br />
VOLATILISATION or LEACHING) from the plant/soil<br />
system.<br />
The increase in yield, or nutrient c<strong>on</strong>tent, <str<strong>on</strong>g>of</str<strong>on</strong>g> a sec<strong>on</strong>d or<br />
subsequent crop after the applicati<strong>on</strong> <str<strong>on</strong>g>of</str<strong>on</strong>g> ORGANIC<br />
FERTILISER (e.g. LIVESTOCK MANURE) that can be<br />
attributed to the initial applicati<strong>on</strong> <str<strong>on</strong>g>of</str<strong>on</strong>g> organic fertiliser.<br />
The increase in the yield <str<strong>on</strong>g>of</str<strong>on</strong>g> a crop arising from applicati<strong>on</strong> <str<strong>on</strong>g>of</str<strong>on</strong>g><br />
PLANT NUTRIENTS e.g. in FERTILISER or MANURE.<br />
The absorpti<strong>on</strong> <str<strong>on</strong>g>of</str<strong>on</strong>g> PLANT NUTRIENTS through the roots, or<br />
sometimes the leaves, <str<strong>on</strong>g>of</str<strong>on</strong>g> plants.<br />
The amounts <str<strong>on</strong>g>of</str<strong>on</strong>g> PLANT NUTRIENTS needed, in additi<strong>on</strong> to<br />
those already c<strong>on</strong>tained in the soil, to obtain a desired,<br />
optimum crop yield.<br />
The total amount <str<strong>on</strong>g>of</str<strong>on</strong>g> a PLANT NUTRIENT c<strong>on</strong>tained in e.g.<br />
LIVESTOCK MANURE in both inorganic and organic forms<br />
The amount <str<strong>on</strong>g>of</str<strong>on</strong>g> a PLANT NUTRIENT c<strong>on</strong>tained in e.g.<br />
LIVESTOCK MANURE in chemical forms that can be,<br />
potentially, immediately taken up by plants.<br />
PLANT AVAILABLE NUTRIENT<br />
The value or worth <str<strong>on</strong>g>of</str<strong>on</strong>g> MANURE etc. (e.g. euros/m 3 ) based <strong>on</strong><br />
the cost <str<strong>on</strong>g>of</str<strong>on</strong>g> providing the same quantities <str<strong>on</strong>g>of</str<strong>on</strong>g> PLANT<br />
NUTRIENTS that it c<strong>on</strong>tains as INORGANIC FERTILISER. It<br />
should be stated whether this is based <strong>on</strong> TOTAL or<br />
AVAILABLE MANURE nutrient c<strong>on</strong>tent.
