118      Two cups (1 pint) fertilizer is equal to approximately 1 pound. Three-quarter pint limestone weights approximately 1 pound.

535      Broadcast dolomitic limestone as recommended, either in the fall or early spring.

630      Establishment: broadcast dolomitic limestone if recommended and 3 lbs 10-10-10 per 1,000 square feet over the area where the pecan tree(s) will be planted and mix into the soil to a depth of 10-12 inches.

For young trees: broadcast 1 lb 10-10-10 fertilizer distributed in a circle around the tree.  Repeat the application in June or July.  The following February, broadcast 4 lbs
10-10-10 for each inch of trunk diameter (measured 1 foot above soil surface) in a circle around the tree.   If the terminal growth is less than 2 to 4 feet, broadcast either 2 lbs
calcium nitrate
(15.5-0-0) or 1 lb 34-0-0 per inch of truck diameter in June or July.  Do not place fertilizer within 12 inches of the trunk.  Broadcast 1 lb zinc sulfate per tree for the first three years following
planting, spreading the zinc sulfate in a circle around the tree outside of the planting hole.  .

For bearing trees: broadcast 4 lbs 10-10-10 fertilizer per tree for each inch of trunk diameter (measured 4-1/2 feet above soil level) in mid-to-late February.  For good nut
production, terminal growth should be approximately 6 inches each year.  If the desired terminal growth is not obtained, adjust the fertilizer rate accordingly.  Zinc nutrition is very important for tree growth and nut production, best determined by analysis of leaves taken in July or early August.  Contact the Home and Garden Information Center at
1-888-656-9988 for leaf sampling and sample submitting procedures.  In the absence of a plant analysis recommendation, each year soil broadcast 1 lb zinc sulfate to young trees
and 3 to 5 lbs zinc sulfate for larger trees.  (Recommendation when phosphorus and potassium soil tests are L-L, L-M, L-S, M-L, M-M, M-S)

 

631   Establishment: broadcast dolomitic limestone if recommended and 1 lb triple superphospahte (0-46-0) and ¼ lb 34-0-0 per 1,000 square feet over the area where the pecan tree(s)
will be planted and mix into the soil to a depth of 10-12 inches.

For young trees: broadcast 1 lb triple superphosphate (0-46-0) and ¼ lb 34-0-0 fertilizer distributed in a circle around the tree.  Repeat the application in June or July.  The
following February, broadcast either 2 lbs calcium nitrate (15.5-0-0) or 1 lb 34-0-0 for each inch of trunk diameter (measured 1 foot above soil surface) in a circle around the tree.
If the terminal growth is less than 2 to 4 feet, broadcast either 2 lbs calcium nitrate (15.5-0-0) or 1 lb 34-0-0 per inch of trunk diameter in June or July.  Do not place fertilizer within
12 inches of the trunk.  Broadcast 1 lb zinc sulfate per tree for the first three years following planting.  Spread the zinc sulfate in a circle around the tree outside of the planting hole.
For bearing trees: broadcast 2-1/2 lbs 16-4-8 fertilizer per tree for each inch of trunk diameter (measured 4-1/2 feet above soil level in mid-to-late February, distributing the fertilizer
in a circle around the tree.  For good nut production, terminal growth should be approximately 6 inches each year.  If the desired terminal growth is not obtained, adjust the fertilizer rate accordingly.  Zinc nutrition is very important in pecan production, best determined by analysis of leaves taken in July or early August.  Contact the Home and Garden Information
Center at 1-888-656-9988 for leaf sampling and sample submitting procedures.  In the absence of a plant analysis recommendation, each year soil broadcast 1 lb zinc sulfate for
young trees and 3 to 5 lbs zinc sulfate for larger trees. (Recommendation when phosphorus and potassium soil tests are L-H, L-EX, M-H, M-EX)

 

632   Establishment: broadcast dolomitic limestone if recommended and 2 lbs 15-0-15 or equivalent fertilizer per 1,000 square feet over the area where the pecan tree(s) will be planted
and mix into the soil to a depth of 10-12 inches.

For young trees: broadcast 2 lbs 15-0-15 or equivalent fertilizer distributed in a circle around the tree.  Repeat the application in June or July.  The following February, broadcast
either 2 lbs calcium nitrate (15.5-0-0) or 1 lb 34-0-0 for each inch of trunk diameter (measured 1 foot above soil surface) in a circle around the tree. If the terminal growth is less than 2 to 4 feet, broadcast either 2 lbs calcium nitrate (15.5-0-0) or 1 lb 34-0-0 per inch of trunk diameter in June or July.  Do not place fertilizer within 12 inches of the trunk. Broadcast 1 lb
zinc sulfate per tree for the first three years following planting.  Spread the zinc sulfate in a circle around the tree outside of the planting hole.
