FORM 13-A621(I) (09-23-2013) 
The sum of irrigated acres harvested in Section 9 
should be equal to or greater than Section 2, item 4, 
column 2, Box C, total acres irrigated. 
Any harvested crop grown in the open not pre-listed 
should be entered under item 19 ‘all other crops.’ 
Report the crop name in the ‘specify’ area. Note: For 
winter wheat, report the acres harvested in 2013. 
Section 10 - Primary Method of Field Water 
Distribution, Water Source, and Acreage of 
Chemigation in Irrigation Water for Crops Irrigated in 
the Open in 2013 
For each crop with irrigated acres harvested reported in 
Section 9, report the primary type of irrigation system in 
the first column by selecting the appropriate water 
distribution ID code from the water distribution ID code 
list above the table. Report the number of acres irrigated 
from each water source (ground, on-farm surface, and 
off-farm suppliers). 
Then, for each irrigated crop, report the number of acres 
that were irrigated applying chemigation, that is, the 
application of fertilizers or pesticides through the 
irrigation water. Report the acres of commercial 
fertilizer application and acres for pesticide application 
separately. 
Note: For each crop, an irrigated acre harvested may be 
reported in both the fertilizer and pesticide columns. 
Therefore, for each crop, the sum of chemigation acres 
may total more than the corresponding irrigated 
harvested acres reported for that crop in column 1 of 
section 9. 
Report the acres of the irrigated crop by water source. 
Section 11 - Irrigation Area, Methods, and Water 
Applied to Horticultural Crops in the Open in 2013 
Report whether this operation irrigated any nursery, 
greenhouse, floriculture, mushrooms, propagative 
materials, or other horticultural crops grown in the open 
in 2013. If any horticultural crops on your operation were 
grown in the open, then complete this section. 
Item 2 - Report the total acres and irrigated acres for 
horticulture crops grown in the open to the nearest tenth 
acre. Report the acres only once even when multiple 
crops were harvested off the same land. Irrigation refers 
to the application of water to land or crops by any 
artificial or controlled means. 
Item 3 - Report acres for each horticulture crop listed to 
the nearest tenth acre. Report acres of each crop 
harvested, even when multiple crops were harvested off 
the same land, For example, if annual bedding plants 
and a nursery crop were harvested from the same 2 
acres, enter 2.0 acres in the Floriculture and bedding 
crops category and 2.0 acres in the Nursery crop 
category. For each category, enter the total acres grown 
in the open and irrigated acres. 
Report for each crop category grown on this operation 
the total acres in the open and irrigated acres in the 
appropriate category: 
a. Floriculture and bedding crops - bedding/garden 
plants, cut flowers and cut florist greens, indoor 
foliage plants, potted flowering plants 
b. Nursery crops - ornamentals, shrubs, shade trees, 
fruit and nut trees, vines, palms, ornamental grasses, 
evergreens not for Christmas trees, deciduous trees 
and shrubs, aquatic plants 
c. Sod 
d. Propagative materials - bulbs, corms, rhizomes, and 
tubers; cuttings, seedlings, linings, and plugs; flower 
and vegetable seeds; tobacco transplants; vegetable 
transplants 
e. Christmas trees and short rotation woody crops - A 
short rotation woody crop is a tree that grows from 
seed to a mature tree in 10 years or less. 
f. Other - If more than one crop was grown for this 
category, report the primary type of crop in the 
specify area. 
Item 4 - Report the area irrigated or watered for 
horticultural crops grown in the open in 2013 by 
irrigation method used on this operation. If more than 
one method was used, report area in all methods that 
apply. Report quantity of water in the unit of measure 
most used for each method. If the total quantity of water, 
column 2a, and the unit of measure, column 2b, is 
known, then skip column 3. 
Report for the following irrigation methods: 
a. Hand Watered 
b. Gravity Irrigation - refers to the free-flowing 
application of water. 
c. Sprinkler - Exclude hand-held sprinklers. 
d. Drip, trickle, or low-flow micro irrigation - the water 
is distributed down the rows by tapes which meter 
out small amounts of water at low pressure near the 
plant's roots. 
e. Subirrigation - this is sometimes referred to as 
water seepage. It is used to maintain a water table at 
a predetermined depth. Normally these systems are 
permanently in place below the rootline. Water is 
usually applied by using emitters. Include hydroponic 
in this category. 
The total area reported, by method used, should be 
equal to or greater than item 2, irrigated area, code 
0738.
