AA International - Crop assessing -Pictorial Evalution Tools
Pictorial Evaluation Tools (PETs).
An objective, ground-based system for specialists/ non-specialists- no satellites, no cameras, no hearsay.
PET- Crops provides you with an objective means of rapidly assessing crop yields of EVERY FIELD you see by comparing your observations with the yields of photo-indicators of YOUR crops previously measured and recorded at harvest.
Look at the field, choose the closest corresponding photo-indicator, read the score, fine-tune the score above-below-or-between the NINE levels offered to guide you; and record the yield in tonnes per hectare (or kg/local area units) on forms provided for you in the PET-manuals for Excel analysis.
Pictorial Evaluation Tools (PETs). 
A standard method of body condition scoring by sight only- no herding, no handling, no touching. 
PET- Livestock allows you to assess livestock body condition by comparing your observations with photo indicators taken of camels, cattle, goats and sheep (fat-tailed and long-tailed) of recorded body condition score from 1(low) to 5 (high) - using one specific site on the body
Herd level- Look at the herd, choose the mode (most commonly occurring score) at or between the 5 grades to guide you; and record the score on forms  provided for Excel analysis. Individual level- score each mature animal; identify class (female-milking, dry, heifer/ gimmer; male- breeding, draught / pack, castrates, fat-stock, store stock) and determine means and ranges for specific classes.
The PET- Livestock manuals also include PET Forages, a pioneering adaptation of PET - Crops for each country's grasses-  to estimate dry matter yield of standing hay.
