It requires an examination of the environmental impacts of each proposed application of a PPP to combat a defined harmful organism in a defined crop.
The typology forgoes the detection of fixed defined crop rotations but has its focus on crop sequence properties and a consideration of the main characteristics of crop rotation practice: i) the transition frequency of different crops and ii) the appropriate combination of crops with different physical properties (e.g. root system, nutritional needs) and growing seasons.
Borras et al. define 'flex crops' as "crops that have multiple uses (food, feed, fuel, fibre, industrial material, etc).

In this paper we define the cropping system yield potential as the output from the combination of crops that gives the highest energy yield per unit of land and time, and the cropping system yield gap as the difference between actual energy yield of an existing cropping system and the cropping system yield potential.
Flowered wallpaper and portions of decorative carpet define the cropped edges of the composition.
Four general layouts may be defined: large crop farms, large stock farms, farms in underdeveloped areas, and small to medium mixed farms.

The water quality of river introduces its potential to use in agriculture for defining the cropping pattern and in industrials to develop the type of industry.
