|
|
Term
| some things UGFERTEX can do |
|
Definition
1. Calculate N, P2O5, K2O, Ca, Mg, S, micronutrients and lime requirements for a
selected crop based on soil test results, the soil management group, and a yield
level obtainable with good management.
2. Modify the nutrient requirements based on the farmer's actual yield goal, previous
crops, and presence of irrigation.
3. Estimate P2O5 and K2O additions required to raise soil test levels the number of
index units entered by the user (the default is 0)
4. Calculate the total nutrient requirement based on 1, 2, and 3.
5. If manure is to be applied, calculate the available nutrients in manure, calculate
the rate of manure to apply, and determine the amount of additional commercial
fertilizers required.
6. Provide additional comments to aid in timing and management of nutrient
applications.
7. Provide a graphically detailed printout of the analysis and nutrient
recommendations (commercial fertilizer, manure, or combination of both) for
field records . |

| Loss of bioavailable P to surface waters is of concern because... |
|
Definition
it can accelerate eutrophication in lakes and streams of
the state. |
|
|
Term
| the main pathways of P loss that the P index considers |
|
Definition
I) soluble P in surface runoff,
II) particulate P in surface runoff,
III) soluble P in leachate. |
|
|
Term
The total risk of P loss from a
field is computed by adding... |
|
Definition
the risk from each of the three pathways.
P Index = Risk of Sol. P in Runoff + Risk of Partic. P in Runoff + Risk of Sol. P in Leachate |

water table or tile water directly connected to surface water. |
